Beginning in January 2010, and building on the 2008 Maguire Group Study, we interviewed Department personnel to determine the space needs for each division within the Department, we prepared an engineering analysis of the building, and we undertook a preliminary zoning and wetlands analysis of the site. Preliminary schematic design options were developed to meet the identified space needs. These options were reviewed with the Permanent Building Committee and over a series of meetings were refined leaving two viable options. One option calls for an addition to and renovations of the present building. The other option calls for building a new structure on the site. Preliminary construction cost and project cost estimates were also prepared for both options. We concluded that, due to modernization and updates to the Massachusetts Building and Life Safety Codes and the enactment of accessibility legislation since the facilities were originally constructed, a major work project undertaken on the building would expose serious Building Code, Life Safety Code and Accessibility Code deficiencies. Its heating, ventilating, air - conditioning, and electrical systems are past their expected useful life, are inefficient and we believe should be replaced. The Fire Station, in addition, is experiencing a structural failure of its apparatus floor and is greatly undersized for its present occupancies and uses. For instance, some of the staff is housed in a trailer adjacent to the building and they are forced to leave some of their apparatus outdoors. Currently, the Fire Department has 11,800 SF of space in the 1947 building but needs a total of 25,100 SF. The 1947 building was designed to support a town community that was half the size of the current population and generated as many calls in a year as are now responded to in approximately two months. The major shortcoming of the building is lack of space. The significant space shortage confirmed in this study should be addressed with a new building. We recommend demolishing the existing building and constructing a new one on the present site. From a response time perspective, the location of the Fire Station is almost ideal. Because of the traffic intersections at the site, the fire apparatus should exit onto Bedford Street rather than onto Camellia Place. Having all the apparatus exit onto Bedford Street cannot be done within the framework of the existing building. The costs to renovate and add on compared to the costs for building a new building are virtually identical. 1 The cost estimate comparisons, including hard construction costs, so- called `soft' costs, and contingency show: Fire Station, Renovation and Addition $13M to $14M Fire Station, New $13M to $14M Temp. Shoring; Cribbing for Apparatus Floor $450,000 If as recommended, it is decided to design a new station on the current site, we project that the A/E fees and owner's costs to complete Design Development, Construction Documents, and Bidding would be in the range of $800,000 to $900,000. These tasks could be completed within the course of a year thus obtaining bids for a subsequent funding request for construction which would be made at a later Town Meeting. The funding request for construction would include fees for construction administration, designing furnishings, and some of the LEED certification fees. In the event that funding for this project is postponed, the further failure of the Fire Station apparatus room floor slab should be addressed in the short term. The shoring of the floor is estimated to cost $450,000, pending discussions with specialty contractors. This shoring would consist of timber cribbing and should be routinely inspected to gauge its condition and remaining life expectancy. Replacement of the slab is not recommended because doing so would require that the building be made seismically resistant at far greater expense. Addressing other major issues with the building fabric and systems can probably be postponed 5 -7 years. However, regular maintenance and normal replacement of failed mechanical and electrical systems should continue. 2 LEXINGTON FIRE STATION SCHEMATIC DESIGN STUDY REPORT Space Needs Summary The present main Fire Station was built in 1946 and has 11,841 SF of space. An additional 972 SF in the form of a trailer housing the Fire Prevention Bureau and an equipment tent of 216 SF have been added in the rear yard. At the time it was built, the Fire Department staff was half full time paid personnel and half "call" or volunteer firefighters. The staff of the Department then was engaged largely in suppression and a limited amount of emergency medical transport. Other significant changes since 1947 affect the space needs of the Department.

In 1993, Lexington commissioned the "Lexington Public Buildings Facility Study ". It stated that the main Fire Station "needs modernization and expansion ", and noted that the Town "should look at the potential for a new Station." In 2000, the "Space /Building Needs Advisory Committee Report" identified a number of shortcomings with the existing building, both in space deficiencies and physical conditions and went on to recommend replacement. In 2008 the Town commissioned the Maguire Group, an A/E firm to study the building. They recommended that the Department needed 22,206 SF to perform its present and future functions. Donham & Sweeney- Architects was retained in January 2010 to review and update the Maguire Study and prepare options for schematic design solutions to meet the Department's needs. Our first step was to revisit the previous space needs study, looking carefully at how the department functions and particularly at their furnishings and equipment needs. In addition to our experience with approximately 20 other fire stations, we took into considerations the recommendations of the National Fire Prevention Association [NFPA 1500] and the Unified Facilities Criteria issued by the Federal Government for use by the Air Force, the Navy, and the Army Corps of Engineers. Our Space Needs Study indicated that 25,134 SF was needed looking ahead 20 to 25 years. This need is comparable to other similar towns.

We found that the present building is woefully inadequate for the tasks being carried out by the Department and that the facility has a number of technical and functional areas of concern. The present building is too small for present staff, equipment & services. This is most clearly seen in compromises to critical operations and equipment: apparatus must be parked outdoors; the Fire Protection Bureau is housed in a trailer. The physical constraints of the building pose challenges to the day to day operation of the Department: apparatus doors are too narrow and too short to accommodate newer apparatus, existing apparatus clears the door openings by 1" and hits the doors when there is snow on the front apron, there is no training space within the building and there is no decontamination space for Fire Fighters, EMTs and EMT equipment. The building contains many issues which, under the present Massachusetts Building Code, would be considered deficiencies. Most prominently, there is no sprinkler system, little universal access, insufficient ventilation and a grossly inefficient heating system. Two of the largest issues regarding the structure itself are the basement and the apparatus floor. The basement leaks badly and cannot be fixed. This is due to the particular nature of the site and the fact that groundwater passes through the site at a high elevation. Considerable funds would need to be spent simply to keep the basement from flooding from time to time let alone prevent the moisture issues that stem from uncontrolled water vapor penetration on a daily basis. The apparatus floor is failing structurally. A full report can be found in Appendix B. It can be briefly stated that the floor possesses only enough strength to avoid a catastrophic failure and is slowly failing. Because the floor system has exceeded its safety factor and is overstressed by a small amount, the failure rate is slow. However, new heavier apparatus cannot be accommodated. With the exception of a large through -wall structural crack in the right rear corner of the Apparatus room, the fabric of the building is in good condition for a 63 year old building. It is our recommendation that if work to replace the station is not carried out, at a minimum, the slab should be shored up as a temporary measure to stop its continued failure. In addition, other deficiencies should be remedied as funds permit. The existing site is well located for response times and a fire station use there should be continued. 0 Due to the extensive nature of renovations required of the present structure and the particular constraints imposed by the configuration of the building, it costs no less to renovate than building new and renovation results in dysfunctional relationships between the particular uses within the building. Detailed structural, mechanical, electrical, and plumbing systems are near the end of their useful life. A detailed analysis of these systems can be found in Appendix C 10 LEXINGTON FIRE STATION SCHEMATIC DESIGN STUDY REPORT Preliminary Plans, Option A- Addition and Renovation SITE PLAN / / IFT EXISTING BUILDING EXISTING SITE PARKING: 29 SPACES 0' 25' 50' 100' F= NEW BUILDING TOTAL DESIGNED PARKING: 29 SPACES II LEXINGTON FIRE STATION SCHEMATIC DESIGN STUDY REPORT Preliminary Plans, Option A- Addition and Renovation FIRST FLOOR PLAN LEGEND smPVLM ROOM ❑ FIRE SUPPRESSION �o ■ ADMINISTRATION PUBLIC ACCESS MECHANICALISERVICE 4.

However, in addition 4 other public bodies will have a design review role; the Board of Zoning Appeals, the Conservation Commission, the Historic Districts Commission, and the Lexington Design Advisory Committee. We recommend that some strategy be developed to coordinate design review among these different bodies. ZONING Reuse of the existing Fire Station lot for an expanded or new Fire station is a permitted use under Lexington's Zoning By -Law. However, a Special Permit with Site Plan Review is required from the Board of Appeals. A traffic study is needed for this Review. In addition, a series of Variances from the Zoning By -Law are needed, including; FAR; 0.20 is the maximum permitted, the plans shows an FAR of 0.36 Site Coverage; 25% is the maximum allowed by Special Permit, the plans show a 30% coverage Height; the maximum allowed is 45', the hose tower is 50'3" high. Parking; 37 parking spaces are required, 33 are provided Parking; 5' building setback required, 2' provided A complete Zoning Analysis can be found in Appendix F. WETLANDS The north corner of the site appears to be in a vegetated wetlands. A botanist will need to flag the edge of the wetlands and the flagging must then be confirmed by the Conservation Commission. Most likely, a full public review of the proposed design by the Conservation Commission and an Order of Conditions will be required. Meeting notes with Lexington's Conservation Officer will be found in Appendix G. 21 HISTORIC DISTRICTS COMMISSION The Fire Station site is within the Battle Green Historic District. The Commission consists of 5 members and they have issues a set of design guidelines that apply to all the Districts. The town will need to apply for a Certificate of Appropriateness and one or more public hearings will be required. The Commission encourages early informal meetings with them as the design is being developed. DESIGN ADVISORY COMMITTEE This Committee consists of 9 members and 8 associates, all of whom are required to be design professionals. The Committee's charge is "to assist the Town in providing professional design guidance for Town buildings ". Their recommendations are made to the Board of Selectmen. 22 LEXINGTON FIRE STATION SCHEMATIC DESIGN STUDY REPORT Preliminary Cost Estimate Summary We estimate the total project costs for the renovation of and addition to the existing building, inclusive of fees, furnishings and other "soft' costs, to range between $13M and $14M with fees and expenses required to bring construction bids to a Spring 2013 Town Meeting ranging from $800,000 to $900,000. The funding request for construction would include fees for construction administration, designing furnishings, and some of the LEED certification fees. The costs for a new building are expected to be the same. Project cost summaries follow. Detailed preliminary construction cost estimates can be found in Appendix E. The detailed construction cost estimates were performed prior to gaining an understanding of the time frame for any future construction work and therefore only show escalation into spring 2011. Subsequently we have been directed to assume construction work would begin in Spring 2013.

This long schedule allows for the extensive public review process required for this project on this particular site. The chart below describes the recommended steps and timing. 27 Fall 2010 Spring 2011 Fa112011 S rin 2012 Fall 2012 Spring 2013 Fall 2013 Presentation to BOS 10/4/2010- 11/9/2010 Spring Town Meeting 03/21/2011 - 5/21/2011 - Design Development 07/01/2011- 11/01/2011 Permitting 11/01/2011- 05/11/2010 Construction Documents 05/01/2012- 11/01/2012 Bidding 01/02/2013-03/01/2013 Spring Town Meeting 03/20/2013- 04/24/2013 Construction Contract Award 05/01/2013- 06/01/2013 Construction 06/01/2013-09-01/2014 27 LEXINGTON FIRE STATION SCHEMATIC DESIGN STUDY REPORT Building Deficiencies and Recommended Work Aside from lack of space, the three principal deficiencies affecting the building are: - the failing apparatus room floor - overhead doors to the apparatus room that are too narrow and too short - persistent water penetration into the basement Other deficiencies are described in the Mechanical and Electrical Engineering Report, Appendix C. They are the expected maintenance and end -of- useful -life items one would expect in a 63 year old building. None of these systems is expected to fail completely in the next 5 to 7 years. The failing apparatus room floor is described in detail in our Structural Engineer's Report found in Appendix B. A report with similar conclusions was prepared by CBI Consulting in 2007 for the Town. The reports indicate the engineer's opinion is that the floor is unlikely to fail completely in the next 3 to 5 years, but it is important to note that the floor cannot support heavier apparatus than currently sits on it. If the Town should decide not to go forward with the recommendation to replace the building in the next 2 to 3 years, then we recommend that the apparatus floor be temporarily shored with timber cribbing. This temporary "fix ", if performed in the next year, is likely to cost in the neighborhood of $450,000 and result in minimum disruption to the Department. The alternative solution, replacement of the slab, is likely to cost in the neighborhood of $1M to $1.5M and require relocation of the Department temporarily at significant cost. Enlarging the apparatus room overhead doors will result in extensive structural changes to the front of the building, most likely requiring seismic upgrading of the building and temporary relocation of the Department. We do not believe that such a significant investment is justified, particularly since, when complete, the building will still be too small for current activities.. The persistent water penetration is a problem that cannot be rectified without an extraordinary expenditure of funds. The Town has already tried moderately priced means of solving the problem to no avail. This is a problem that will only go away by replacing the building with one that has no basement or by constructing an addition that houses the functions currently housed in the basement and abandoning the basement. 29 LEXINGTON FIRE STATION SCHEMATIC DESIGN STUDY REPORT Fire Station Location We understand that discussion has occurred over the years as to whether the space pressure could be relieved in the present building by building a third fire station in the southwest sector of Town. We are told that previous investigations of this solution reveal that a third station would require that staff be added to the Department. Such costs are significant and not politically palatable. Belmont MA, for instance, reduced their number of fire stations from 3 to 2, in part for this reason. Discussion has also occurred on the topic of abandoning the present building and constructing a new one elsewhere, thereby avoiding the costs of temporary relocation. However, studies have shown that the present building is nearly ideally located from a call response time point of view. The National Fire Prevention Association [NFPA] sets a standard of a preferred response time of 4 minutes and an acceptable response time of 6 minutes. The Insurance services Organization [ISO] sets a standard of a 1.5 mile radius for an engine company response and a 2.5 mile radius for a ladder company response. The maps in Appendix H show that the present location achieves the 2.5 mile radius for about 95% of the Town and the 1.5 mile radius is achieved for about 75% of the Town. Moving the Headquarters Fire Station more than a few blocks negatively alters these relationships. 31 LEXINGTON FIRE STATION SCHEMATIC DESIGN STUDY REPORT Appendices A. Detailed Space Needs Report B.

Structural Systems Analysis ROOME & GUARRACINO, LLC Consulting Structural Engineers 48 Grove Street Somerville, MA 02144 Tel: 617.628.1700 Fax: 617.628.1711 June 2, 2010 Mr. Jeff Shaw, A.I.A. LEED AP Donham & Sweeney Architects 68 Harrison Avenue Boston, MA 02111 Reference: Lexington Central Fire Station - Lexington, MA Existing Conditions Study Dear Jeff: This letter summarizes our findings regarding the present condition of the structure of the Lexington Central Fire Station Building in Lexington, Massachusetts, and our recommendations regarding future uses of the structure. These observations and recommendations are based on information provided to us by your office, as well as, our field observations of May 6, 2010. There are existing Structural and Architectural drawings for the original building construction, and as such, we have a good understanding of how the building is framed. Our field observations were only visual surface observations, we have not cut any holes in building finishes, to verify structure, nor have we done any testing to determine the structures underlying condition. Existing Conditions On May 6, 2010, I toured the existing Lexington Central Fire Station Building with Brett Donham, of Donham & Sweeney Architects, the project architects. The existing Lexington Central Fire Station is an L- shaped structure. The main building is two stories, plus full basement, accessible attic, and roof, and is for personnel and administration uses. There is a single story wing for the apparatus bay with a maintenance bay behind. This building was built in 1945 to be a fire station, and has functioned as such ever since. The administration/personnel wing of the building has a full cast -in -place concrete foundation, with a framed basement floor slab and spread footings. Most of the first floor (used for offices, the kitchen, and common room) is framed with 2x10's @ 16" c/c dimensional lumber supported on either concrete bearing walls or steel beams and posts. A small portion of this floor (under the old alarm, battery, and utility rooms) is framed with a one -way reinforced concrete slab. The second floor, which houses the living quarters, is also framed with 2x1O's @ 16" c/c dimensional lumber supported on either steel beams, wood framed bearing walls, or an 8" brick bearing wall on the interior, and multi -wythe masonry bearing walls on the perimeter. The attic is partially accessible and framed with 2x1 0's bearing on wood framed partitions that form the second floor corridor walls. The gabled roof is framed with 2x 10's @ 20 "c /c rafters spanning from exterior bearing walls to a ridge board, wood board planking, and asphalt shingles. Exterior walls above the first floor are generally 12" thick, multi -wythe unreinforced brick masonry bearing walls. The unreinforced masonry bearing walls also act as shear walls to provide lateral stability for the building under wind and seismic loadings. ROOME & GUARRACINO, LLC Page 2 The apparatus bay wing is attached to the personnel /administration wing of the building, and is a single story structure. The apparatus bay floor and the maintenance bay floor behind are a framed two -way reinforced concrete slab and a one -way reinforced slab respectively. Both slabs are supported on reinforced concrete beams, piers, and spread footings. Below each slab is a limited access crawl space area with exposed earth. In the SE corner of the apparatus bay, there is a small steel framed mezzanine, used for weight training that is supported off the framed slab floor and off the exterior masonry bearing walls. There is a wood framed storage mezzanine at the south end of the maintenance bay. The gable roof of the apparatus bay is framed with four steel trusses clear spanning from side to side. Steel beam purlins span between the trusses at the ridge and at third points between, supporting 2x6 rafters, wood board planks, and asphalt shingles. A plaster ceiling is hung from the bottom chord of the trusses over the apparatus bay. The roof of the maintenance bay is essentially flat, and framed with clear spanning steel beams and 2x10 rafters spanning over the steel beams. Lateral stability is again provided by the 12" thick unreinforced mylti -wythe masonry bearing walls. Steel lintels span all masonry openings. Based on notes on the original structural drawings, the floors of the administration/personnel wing were designed for a live load of 50 psf, the sloping roofs for a live load of 25 psf, flat maintenance bay roof a live load of 40 psf, and the apparatus and maintenance bay floors for a live load of 250 psf. Our analysis of the framing using the allowable stresses gleaned from the drawings, indicates that in all cases except for the apparatus bay floor, that the structure was in fact designed for the stated loadings. We find that the apparatus bay in actuality is capable of carrying in the neighborhood of 200 psf (based on design standards of today). Based on the stated loadings, other than the first and second floors (offices and residential) and the maintenance bay floor, the code mandated live loads of today are higher than those presently designed for. The sloped roof live loads are below present code mandates, and the flat roof loadings for the maintenance bay does not include adequate loads for drifted snow. The apparatus bay floor load of approximately 200 psf is well below the loading required for modern trucks. While the structural framing for most of the administration/personnel wing is not visible, as ceiling finishes cover the framing, there is no evidence of major structural distress. There are signs of significant water infiltration into the basement, as evidences by some puddles on the floor and new water marks about 16" up on the walls. The basement floor slab is also badly cracked in a number of areas, (specifically in the boiler room) possibly the result of water pressure from below. There is some cracking in the tops of the foundations walls, most noticeably at corners. The upper floors and the roof show no evidence of structural problems. There is no evidence of significant foundation settlement or major foundation wall cracking. The interior masonry partition/shear wall looks good, with no signs of cracking. The exterior of this portion of the building looks good, with only some very minimal cracking of masonry that will need repointing. The structure of the apparatus bay wing is not in as good condition. The floor of the apparatus bay is showing some significant deflections and is severely cracked in a number of locations. (Most likely the result of being overloaded.) When reviewed from the underside, in the crawl space, some of the cracks appear to extend entirely through the slab, as evidenced by efflorescence and water staining, and there are areas of spalling concrete and exposed and rusting reinforcing steel. The slab of the maintenance bay also shows some cracking. There is a large vertical crack in the interior of the SE corner of the apparatus bay, which appears to be related to the cracking of the exterior masonry corner. This masonry corner appears to have partially separated and moved outwards. It was patched at some point in the past. ROOME & GUTARRACINO, LLC Page 3 The bearing wall between the apparatus bay and the maintenance bay is also showing signs of distress, probably settlement related as is the nearby corner. The roof and attic framing appear to be in good condition, although there. is significant sign of efflorescence and moisture in the masonry of the east gable end wall. Some lintels are showing signs of rust, but other than the SE corner of the apparatus bay (previously mentioned) the exterior masonry walls appear to be in fairly good condition with only very minor cracking in need of repointing. Despite the problem mentioned, the building structure generally appears to be in fairly good condition and well maintained. Addition/Renovation Feasibility It is our understanding that you are interested in a number of possible options for renovating and adding to the existing structures, in an effort to add needed space, and to accommodate changes in program. Option 1. Provide a new separate structure for the apparatus and other spaces as needed, move office and administration uses into the present apparatus bay, and do minimal structural work to the existing building. Under this option any new structure would be structurally isolated by an expansion joint from the existing structure. The new structure could be built to any size and configuration, would be designed and built to the requirements of the latest edition of the State Building Code, and would have no impact on the existing structure. Our review of the existing structure indicates that minor renovations to the existing structure are possible, as long as the exterior load bearing masonry walls and the interior load baring masonry walls are basically left in tact, as they provide the lateral bracing system for the structure. Large -scale removal of these shear walls would violate the building code provisions against weakening an existing building's lateral system, which would necessitate a seismic upgrade to the entire structure, which we do not recommend as it is usually very difficult and costly. Turning exterior windows into doorways by removing the masonry below the sill is not a problem, but significantly increasing the width of a number of exterior openings or combining openings by removing masonry jambs may trigger an upgrade. Our analysis of the lateral loads on the structure as required by the Mass. Building Code in Section 3408, and our discussion with you about renovation options, indicates that structural work proposed would be classified as "Level 1 Work ". Under "Level 1 Work" the interior and exterior shear walls must be left intact, while some of the interior partitions are not structural and may be modified or removed. Any additions attached directly to the existing structure would have to be kept small, so as to not trigger a complete seismic upgrade of the building. A small roof or canopy would be small enough so that it could be connected directly to the existing structure, and not pose any structural complications. Any larger addition would need to be separated from the existing structure by an expansion joint (as discussed above). Under the present seismic code expansion joints generally need to be 2" to 3" wide for each level above grade. (The roof of a two story building would have a 6" to 9" joint.) Generally, minor structural changes required to add or modify stairs, elevators, add mechanical openings, or add roof skylights are fairly simple, and do not have a major impact on the existing building structure. The apparatus bay could be used for personnel and offices uses, as those uses have a much lower live load requirement than the present truck loadings. Mechanical upgrades to the building are also feasible. New openings required for ducts, piping, etc. in the roof deck or in the framed floors can be accommodated as long as the openings fall between the existing framing ROOME & GUARRACINO, LLC Page 4 members and do not interfere with the framing. Small openings, 12" or less, can be accommodated with out any additional framing. Larger openings may need some supplemental framing between primary structure. New major openings that would interrupt existing framing can also be accommodated by adding new framing if necessary. Under this option, we would recommend that the apparatus bay floor slab be repaired and sealed to keep our moisture from the crawl space below. (Fill cracks, repair severely corroded reinforcing steel, and patch spalled concrete.) Additionally, exterior brick should be repointed where needed, corroded lintels should be cleaned of rust and repainted with a zinc rich paint (replaced if severely damaged), the corner foundation cracks should be repaired, and the large vertical crack in the SE corner of the apparatus bay repaired. Collar ties (2x6's) should be added to the existing roof framing of the large gable roof over the administration/personnel wing of the building. Option 2. Keep building essentially as is, do minimal structural work to the existing building other than rebuild the apparatus bay floor. Our review of the existing structure indicates that minor renovations to the existing structure are possible, as long as the exterior load bearing masonry walls and the interior load baring masonry walls are basically left in tact, as they provide the lateral bracing system for the structure. Large -scale removal of these shear walls would violate the building code provisions against weakening an existing building's lateral system, which would necessitate a seismic upgrade to the entire structure, which we do not recommend as it is usually very difficult and costly. Turning exterior windows into doorways by removing the masonry below the sill is not a problem, but significantly increasing the width of a number of exterior openings or combining openings by removing masonry jambs may trigger an upgrade. Our analysis of the lateral loads on the structure as required by the Mass. Building Code in Section 3408, and our discussion with you about renovation options, indicates that structural work proposed would be classified as "Level 1 Work ". Under "Level l Work" the interior and exterior shear walls must be left intact, while some of the interior partitions are not structural and may be modified or removed. The removal and replacement of the apparatus bay floor would be permitted under "Level 1 Work" as it is not considered part of the seismic resisting system or effective seismic weight, and it is a "framed floor laterally braced by foundation walls ". Generally, minor structural changes required to add or modify stairs, elevators, add mechanical openings, or add roof skylights are fairly simple, and do not have a major impact on the existing building structure. Mechanical upgrades to the building are also feasible. New openings required for ducts, piping, etc. in the roof deck or in the framed floors can be accommodated as long as the openings fall between the existing framing members and do not interfere with the framing. Small openings, 12" or less, can be accommodated with out any additional framing. Larger openings may need some supplemental framing between primary structure. New major openings that would interrupt existing framing can also be accommodated by adding new framing if necessary. Under this option, we would recommend that the apparatus bay floor be removed, that all unsuitable soils be removed down to the competent soil bearing elevation, (presumably the elevation of the present footings) and that controlled structural fill be placed. Based upon geotechnical engineering information that we have from nearby projects, in lieu of removal and replacement of soils, a soil improvement option of "Rammed Aggregate Piers" could be used to eliminate the need to take potentially contaminated soils off site. In either case a new 8" thick slab -on -grade w /reinforcing ROOME & GUARRACINO, LLC Page 5 steel and welded wire fabric (for crack control) could then be installed for a new apparatus bay floor. that would be able to safely support the loads imposed by any modern day pieces of equipment. Additionally, exterior brick should be repointed where needed, corroded lintels should be cleaned of rust and repainted with a zinc rich paint (replaced if severely damaged), the corner foundation cracks should be repaired, and the large vertical crack in the SE corner of the apparatus bay repaired. Collar ties (2x6's) should be added to the existing roof framing of the large gable roof over the administration/personnel wing of the building. Option 3. New construction. For cost and flexibility reasons, we would recommend that any new construction (either a complete new building or a separated addition to the existing structure) be framed in structural steel, with a slab -on- grade for the lowest level floor, steel beams and concrete on steel deck for all framed floors, and steel beams and steel roof deck for the roof. Braced frames of structural steel would be the least expensive system for providing stability for wind and seismic loadings. Based on the information that we were able to glean from the existing drawings it appears that any new foundations would be spread footings. Other structural systems and building types are possible and can be properly vetted once an actual building layout is proposed.

The building is zoned in half (East and West). The first and second floors of each half of the building are on the same zone, as steam piping is up fed from the basement, through the first floor, and to the second floor. Steam condensate is returned to the boiler feed system by gravity. The West zone control valve is controlled by a wall mounted thermostat located on the first floor and the Eats zone is controlled by a wall mounted thermostat on the second floor. This piping configuration, limited zone control and the high number of terminal heating units with damaged or malfunctioning controls typically results in un -even space temperature control and complaints.

RECOMMENDATIONS In general the Fire Station's heating, ventilation and air conditioning systems do not meet the thermal comfort needs, energy efficiency and code - requirements of a modern day Fire Station. Therefore we recommend the following HVAC system replacements: Heating System: The existing steam boiler and steam radiator heating system is extremely in- efficient in comparison to today's energy efficient heating systems. A large amount of heating fuel cost is wasted through piping heat loss (un- insulated piping, steam traps, etc.), inadequate zone control, and as a result of using operable windows for ventilation (and as a means of temperature control in areas which over -heat) during heating seasons. The existing steam and condensate return piping distribution system has exceeded its useful service life and will continue to require increased maintenance and repair costs. We recommend that the existing steam boiler is replaced with a high efficiency gas -fired condensing hot water boiler plant, consisting of boiler, pumps equipped with VFD drives, DDC controls (including outdoor air reset) and accessories. A new steel /copper piping distribution should be provided to replace the existing steam piping. The piping should be designed and installed in a manner which provides improved zone control capabilities through the use of two - way modulating zone control valves and remote wall mounted thermostats. GARCIA • GALUSKA • DESOUSA Consulting Engineers Inc. Lexington Fire Station Lexington, MA Existing Conditions Systems Report J #640 017 00.00 L #30749/Page 12 /June 23, 2010 The basement, first and second floor areas of the building should be heated by terminal hot water heating systems. Energy efficient heating systems such as fan coil units could be installed to replace the existing steam radiation as part of a building renovation project. Fan coil units could also be used to provide air conditioning to areas utilizing the same piece of terminal equipment. The apparatus bay and repair garage unit heaters should be replaced with new hot water heating unit heaters. Alternatively, a radiant floor heating system could be installed for these areas and smaller unit heater could be provided for supplemental heating. Ventilation: We recommend that a new mechanical ventilation system be designed and installed to provide year -round ventilation for the building. It is recommended that a new ventilation system be provide with energy recovery and supplemental heating and cooling capability. This would allow the system equipment and associated ductwork distribution system to be sized based solely on ventilation and make -up air requirements. This approach would result in lower first installed cost, improved energy efficiency and improved thermal comfort and indoor air quality. The apparatus bay vehicle exhaust air system appears to be in good condition, and it appears that the system fans and ductwork distribution system could be re -used. It is recommend that the system is fully tested, repaired as required, and commissioned if the system is re- configured as part of a renovation project. Additional modifications, such as additional ductwork, fans, control, etc would likely be required if the apparatus bay and garage are expanded as part of a renovation. Air Conditioning: While the existing AC system air handling units and associated air cooled condensing units have been installed rather recently and appear to be in good condition, we recommend that a new energy efficient air conditioning system is installed. The existing AC unit condenser efficiencies are below building code energy efficiency requirements. In addition the units are under -sized to properly temper mechanical ventilation required by the building code. The existing air handling units and air cooled condensing units could potentially be re -used to serve the AC needs of dedicated areas of the building or could potentially be used by the Town for another building. As described above, a hydronic heating and air conditioning systems such as a fan coil unit system could be utilized to provide both heating and cooling to the building. An indoor modular high efficiency chiller, connected to a remote split system with an air cooled condensing unit located outdoors, would provide chilled water to the fan coil units through a steel and copper piping distribution system. Chilled water pumps would be equipped with variable speed drives for increased energy efficiency. GARCIA • GALUSKA • DESOUSA Consulting Engineers Inc. Lexington Fire Station Lexington, MA Existing Conditions Systems Report J #640 017 00.00 L #30749/Page 13 /June 23, 2010 Controls: We recommend that all new HVAC systems are controlled by a newly installed direct digital control, energy management system for improved thermal comfort control and energy efficient system operation. General Notes: While preparing our HVAC system existing conditions study and system recommendations report, we have reviewed the previous Existing Building Evaluation report dated 12/23/2008 by Maguire Group, Inc. In general, we concur with the existing conditions findings outlined in that report. We would also agree that if a renovation and addition project did not occur that there are numerous HVAC system repairs and improvement that should occur. In this instance, we would recommend that the highest priority, major repair items would include the following: Inspection and testing of the steam heating system; Replacement of all defective control valves and steam traps; Replacement of bathroom and shower room exhaust fans; and installation of insulation on bare steam and condensate piping. If a building renovation and HVAC system renovation did not occur, the following HVAC systems would most likely need to be replaced with the next ten (10) years. 1. Steam boiler, associated boiler feed pump set and controls. 2. Three (3) main stream zone control valves. 3. Majority of individual radiator thermostat control valves would require replacement. 4. Steam return condensate traps would require continual maintenance and replacement. 5. Fuel Oil Tanks 6. Basement Heating Unit 7. Steam radiators would require continual repairs. 8. Bathroom exhaust fans. 9. Second Floor Dormitory central exhaust air fan 10. First and Second Floor AC units and associated ACC condensing units would require repairs. 11.

Municipal sewer and municipal water service the Building. The majority of the plumbing systems are original to the building. Portions of the system have been updated as part of building renovation projects. The plumbing systems could continue to be used with maintenance and replacement of failed components; however other non - dependent decisions will likely force the plumbing upgrade. The plumbing fixtures are in fair condition. Attempts have been made to upgrade a few bathroom fixtures however no fixtures meet current accessibility codes. Current Access Code requires accessible fixtures wherever plumbing is provided. In terms of the water conservation fixtures, their use is governed by the provisions of the Plumbing and Building Code. Essentially, the code does not require these fixtures to be upgraded, but where new fixtures are installed, as may be required by other codes or concerns, the new fixtures need to be water conserving type fixtures. Fixtures: The water closets are predominately floor mounted vitreous china with manual flushometers. Urinals are wall hung vitreous china with manual flushometers.

The majority of roof drainage is collected by a series of gutters and downspouts which discharge below grade into 6" PVC piping. A couple downspouts on the side of the Maintenance Bay discharge onto the asphalt. Typical Downspout Termination Typical Bedford St Downspout Termination There is groundwater puddling on the floor of the basement Storage Room with no means of draining it by gravity. We're told that the ground water table is high causing the water infiltration condition. There are reports that there are two sumps and pumps, one in each crawl space which pump infiltrating ground water and pumping it to the storm drainage system however we could not confirm this.

GENERAL NOTES: While preparing our Plumbing system existing conditions study and system recommendations report, we have reviewed the previous Existing Building Evaluation report dated 12/23/2008 by Maguire Group, Inc. In general, we concur with the existing conditions findings outlined in that report. We would also agree that if a renovation and addition project did not occur that there are numerous Plumbing system repairs and improvements that should occur. In this instance, we would recommend that the highest priority, major repair items would include the following: Provide an MDC Gasoline /Oil /Sand interceptor and connect the Apparatus Bay and Maintenance Bay floor drains to the interceptor and discharge into the municipal sewer; provide basement under slab drainage piping and pumps to bring about a dry basement; provide accessible toilet room fixtures on the first floor; convert the oil water heater to a high efficiency gas water heater with a recirculation system and master mixing valve; upgrade locker room with new water conserving plumbing fixtures. RECOMMENDATIONS: Provide the domestic water heater with a master mixing valve to allow the storage of water at 140 degrees to avoid Legionaire's Disease. Provide the water heater with a recirculation system to provide fixtures with hot water within seconds and avoid wasting water. Provide service sink faucets faucets with vacuum breakers to protect the potable water and comply with code. Insulate all water piping at the water heater to conserve energy. Provide a Gasoline /Oil /Sand Interceptor for the Apparatus & Maintenance Bay floor drains and connect to the sanitary sewer. The interceptor will keep gasoline & petroleum products and sand out of the sanitary and storm sewers and comply with the plumbing code. Provide basement below slab drainage piping and pumps as may be recommended by Geo- technical Study to bring about a dry basement. GARCIA • GALUSKA • DESOUSA Consulting Engineers Inc.

LEXINGTON FIRE STATION SYSTEM NARRATIVE SECTION 15500 - HVAC PAGE 2 June 21, 2010 L #31068/J #640 017 00.00 B. Powerplant The primary equipment located in the powerplant will include a two high - efficiency 400 MBH gas -fired condensing boiler located in the proposed mechanical room. The boiler will be vented by a stainless steel breeching which will terminate above the roof. Combustion air for the boiler room will be ducted directly from the outside through a galvanized inlet duct provided with motor operated dampers. Heating hot water will be distributed throughout the building through a fiberglass insulated copper distribution system which will include a primary and standby in -line pump each at approximately 80 GPM. Each pump will be provided with a variable frequency drive which will vary flow in the distribution system as control valves modulate open and close resulting in energy savings. 2. Chilled water will be generated by a 40 ton high- efficiency air cooled chiller. The chilled water system will be provided with a mixture of propylene glycol and water to prevent freezing at a concentration of approximately 35% by weight. Chilled water will be distributed throughout the building through a fiberglass insulated copper distribution system which will include a primary and standby in -line pump each at approximately 90 GPM. Each pump will be provided with a variable frequency drive which will vary flow in the distribution system as control valves open and close resulting in energy savings. C. Ventilation System The central ventilation system will include an air handling unit, with an approximate capacity of 7000 cfm, which will be of the 100% outside air design. The air handling unit will be provided with MERV 13 filters, direct expansion (or chilled water) cooling coil discharging 65 °F air at relatively low humidity level, supply and return fans with variable frequency drive, hot water heating (or gas fired furnace) with modulating control, energy recovery coil, and hot gas reheat. The unit will provide ventilation air to each induction unit through a fiberglass insulated galvanized sheet -metal distribution system. The supply air to each space will be returned through a separate galvanized sheet -metal return air system back to the air handling unit where it will pass through an energy recovery coil which will transfer heat from the exhaust air stream to the outside air intake stream for preheating.

Space Heating and Air Conditioning Heating and air - conditioning of the individual heated and air - conditioned occupied areas will be through the use of ceiling mounted air induction units. Each unit will be a combination of supply air and return air which through the primary air provided to the induction unit through the ventilation system, will induce room air and mixed with the primary ventilation system air where it will pass through the heating and cooling coils located within the induction unit for redistribution to the space. Control valves located in both supply lines of the hot water and chilled water branch piping system will receive control signals from space mounted thermostats to operate the respective control valve to maintain the space temperature setpoint. Each induction unit will be provided with a unit mounted drain pan which will collect condensate during dehumidification and through a separate PVC condensate drain system will discharge the condensate to the building exterior. 2. Ceiling mounted return air registers will be installed in each occupied room which will return air back to the ventilation system air handling unit in an equal amount to the primary air provided to each induction unit where it will pass through a unit mounted energy recovery coil. E. Apparatus Bay /Support Areas The Apparatus Bay will be provided with ceiling suspended horizontal unit heaters located in front of each overhead door. Each unit heater will be provided with a separate wall mounted thermostat for area control. Heating hot water will be distributed to each horizontal unit heater through the central recirculating hot water distribution system which will be located at the ceiling of the space. The apparatus Bay will also be provided with a carbon monoxide /carbon dioxide monitoring and control system which will automatically energize a specialized area exhaust system as contaminant levels rise throughout the space. In addition, a vehicle exhaust capture system will be the primary source of combustion byproduct collection which and will include a primary exhaust system located at the ceiling of the apparatus bays with individual flexible tailpipe connections which will attach to each vehicle venting to a specialized centrifugal exhaust fan located at the ceiling of the space discharging to the exterior. As the vehicles are started and exit the building, the exhaust system will automatically start, and as the vehicles leave the building a specialized breakaway connection from each tailpipe will allow unobstructed exit. 2. The support areas which include turnout gear, gear storage, and generalize maintenance will be provided with heating and ventilation air from the central boiler and air handling systems. A dedicated exhaust fan will be provided and interlocked with the ventilation air system operation.. 3. The proposed drying tower will be provided with an individual roof mounted exhaust fan which will be energized by a single wall mounted switch in the area of the tower when hose drying conditions occur. 4. The proposed DeCon /Bio Hazard rooms will be provided with an dedicated exhaust fan which will be energized by a single wall mounted switch in the area.

Entryways, Stairwells: Entryways, vestibules and stairwells will be heated by hot water cabinet unit heaters. G. The tele -data server room, and elevator machine room will be provided with dedicated split system AC units with remote outdoor condensing units. H. The kitchen will be provided with a dedicated kitchen exhaust fan and make -up air system. I. Automatic Temperature Controls (DDC) Automatic temperature controls will be of the DDC (direct digital control) /electronic actuation design for the operation of all HVAC systems and equipment. A central communication network will be provided for the monitoring of all space temperatures, system setpoints, and overall control for the entire HVAC system. A central PC will also be provided as a user interface for access to the entire automatic temperature control system. 5. HVAC SYSTEM DESCRIPTION (OPTION A - RENOVATION / ADDITION) A. In general the HVAC systems described above would be installed as part of a Renovation /Addition. However the following revisions to the system would need to occur: The renovated existing building area ceiling heights would not allow for the installation of active chilled beam(induction) units. Therefore we recommend that vertical type 4 -pipe fan coil units are installed to serve these areas. It is proposed that 4 -pipe induction units be installed to serve the addition areas of the building provided that sufficient ceiling height is provided. 2. The boiler plant capacity described above would need to be increased to account for increased floor area and the existing building envelope construction. It is estimated that (2) boilers with a capacity of 600 MBH each would be required and that hot water pumps would have a capacity of 120 gpm each. 3. The chiller plant capacity described above would need to be increased to account for increased floor area and the existing building envelope construction. It is estimated that the chiller capacity would have an approximate capacity of 50 tons and that chilled water pumps would have a capacity of 120 gpm each. 4. Lastly, due to existing ceiling height restrictions within the existing building, it is likely that two (2) ventilation air handling units would be required in order to better match the unit size and associated ductwork sizes to the renovation and addition building areas. It is estimated that (2) air handling units, each with a capacity of approximately 4000 cfm, would be required. GARCIA • GALUSKA • DESOUSA Consulting Engineers Inc.

The site would be classified as a redevelopment site which provides a little more flexibility as compared to a new site. Mark said that the D &S team would represent the PBC before the Conservation Commission and the Board of Appeals.

What I did say is that you may be able to make the case to keep the limits of pavement as exists by showing significant improvements to the resource area and buffer zone by implementing stormwater management best management practices and removing invasive species from the natural buffer along the edge of the wetland and enhance with native plantings. I also suggested meeting informally with the Commission once you have the wetlands boundary delineated on a survey plan and some sketches to get some feedback from the Commission before finalizing the design.

Early this summer we had a topographic and utility survey of the site prepared for the Town. It showed a small body of water just to the northwest of the site. When I looked at the site on Tuesday this week, the water had evaporated leaving mud behind. The site has paved parking surfaces that are closer than 50' to what had been the edge of the water and what is now mud. The adjacent building, which houses Ne[lios Gourmet Shop, has a 4" CI pipe that drains onto the ground and then into the body of water or mud. The site is strongly preferred as the location for the Fire Headquarters, new or renovated and expanded. The Fire Departmant needs to roughly double the size of the present building. Emergency vehicle response time and access to multiple radial roads from the site is considered ideal. Howefver the site is small and determining the location of the wetlands edge and the 50' buffer will be critical to the site design and the usability of the site for an expanded Fire HQ.

Donham distributed copies of the Draft Space Needs Report for the Police Department. Questions were raised as to whether some of the spaces described were too generous. D &S was asked to compare Lexington's space needs with other towns. The generator[s] should be secure. A space layout for the Fitness Room was requested. The Police Department was asked to prioritize their space needs and explain how their operations will be improved by the space increases. Chief Corr will be setting up an internal review of the Draft. B. Donham reported that a contract for a topographic and utility survey of the fire station site had been let and the survey was expected by May 5 or 6. The Draft Zoning Analysis showed that several Variances and Special Permits will be needed. A meeting will be set up with Dave George to review the Draft including whether the fire station is in an historic district. Site plan options for the Police Department expansion were reviewed. A decision was made that this project would not include moving the White House to make room for the Police Station. D &S was directed to a parking expansion layout prepared by David Handlin. The project is generally on schedule; the site analysis is ahead of schedule while the analysis of the existing buildings is behind schedule. The next meeting is May 11.

Donham described the changes to the zoning analysis resulting from a meeting with Dave George, the Town's Zoning Administrator. Both buildings are in different Historic Districts. Both buildings will probably need a number of items of zoning relief. D. George said there is a possibility that town Counsel might rule that town buildings are exempt from zoning regulations. That has not been confirmed. D &S to send a copy of the zoning analysis with these meeting notes. • B. Donham distributed a copy of the revised Space Needs summary for the Fire Department. The fire Chief said it was generally acceptable and details can be worked out in the design phase. • Discussion was held on the issue of the petroleum plume clean-up on the Fire Station site. M. Barrett was asked to contact the Town Manager to determine what kind of encumbrance on the future use of the land this presents. • J. Shaw presented 2 concept design options for the Fire Station. Comments included; • Look at the possibility of a new station on the site • Addition to the present building does not need to be a "Colonial" copy; t a well designed contemporary building is preferred over a poorly designed fake Colonial • One ambulance is cross staffed with a ladder truck • Traffic signaling needs to be reconfigured; the cost for doing that should be included in the report • B. Donham described his meeting with Police Department staff and the resulting changes [additions] to the Space Needs Program. There was expressed some concern about the increases to the size of the range, the locker room and the sallyport. The Committee asked for comparative data with other police stations. The sally port envisioned by the Department is a 68 Harrison Avenue 4 Head Tide Church Rd.

J. Shaw presented 3 concept design options for the Police Station. Comments included; o Range to be eliminated. D &S to include in the report the costs for a new inexpensive facility at the Hartwell Avenue site. o Explore possibility of the main level of the addition being raised above the main level of the existing facility; requires ramps or elevator for accessibility. The project is generally on schedule; the zoning analysis is ahead of schedule, the concept design work is on schedule, and the analysis of the existing buildings is behind schedule. The next meeting is June 8. D &S was asked to bring some rough cost estimates.

J Shaw presented an option that retained the existing building and one that proposed a completely new structure. Scheme A shows renovations and additions to the existing building. The structural engineer says the revised Building Code sets limits on the amount of renovation that can be done to the existing building without completely gutting it to install a seismically resistant new structure. An earlier approach of creating a second floor in the present apparatus room has therefore been abandoned. Scheme A will require a complete reworking of the intersection [curbing, radius, lights, utility poles, etc.], which will, in turn, require the Mass Highway Department to review and approve any changes (road is a State Highway). The floor plan is stretched out and not very efficient because of working with the existing building and, as a result its floor area is larger by 2,194 S.F. Other issues needing to be addressed in Scheme A include; o The Captain runs the morning roll call in the Day room and needs to be close o There needs to be a security separation between administration and suppression staff /spaces o The boiler needs to be serviced without going through the administration spaces o The shift commander vehicle needs to be closer to Captain's Office. o Locate Medic trucks 1, 2, and 3 next to one another in the first 2 bays o The first line response is Medic 1, Engine 1, Engine 2, ladder, staff car 68 Harrison Avenue 4 Head Tide Church Rd.

Office, and Captain Office, all on the second floor • The administration side to house Hazmat Office, Fire Prevention, and Fire Investigation • Use of the training Room is mostly internal, not public and needs to have good straight access to the Apparatus Room. • Locate the contaminated W/D next to deluge shower • Eliminate First Aid Triage. Make First Aid Storage twice as big • The EMS Office needs a secure closet for narcotics storage Scheme B is a new building with 5 apparatus bays facing Bedford Street and the administrative wing in the rear. Because it is more efficiently laid out this scheme has about 2,000 SF less floor area than Scheme A. comments included; • Captains and Lieutenants should be closer to the apparatus room • The Kitchen/Dining and the Day room each need to accommodate 10 people • The Plan Review Room should have an outside window • The hose tower should have a stair and a standpipe for training purposes. They will hang 12 lengths of 50' hose • Locate the Assistant Fire Chief next to Fire Investigation and Fire Prevention. Reverse with HazMat Parking Needs are; 0 9 -10 for the suppression shift 0 9 -10 for the shift change 0 5 Administration o 10 -12 public and emergencies • Total is 33 to 37 spaces. -2- Donham & Sweeney Brett Donham, Principal, AIA A R C H I T E C T S Jeffrey D.

Detective, Lexington Police Department Detective, Lexington Police Department Lexington Police Department Project Manager, Department of Public Facilities D &S D &S D &S The purpose of the meeting was to review 2 options for the layout of program for the Police Station. The major difference being the location of the sallyport and detention areas. The discussion compared the features of each arrangement and comments were not specifically related to individual plans. Those comments received include: • The OIC location is critical; preference would be to have the space centrally located to all parts of the building. Also important is quick access to detention. Location in option A was preferred. • Training Room: should have direct public access to public lobby and public bathrooms so there will not be any need to buzz the public back and forth. • Detectives: should be directly accessible to evidence and court prosecutor. Consider placing all these spaces on 3rd floor. • Police Chief prefers to be on the South side of the building if possible, but with good accessibility to critical operations. • At this department, officers bring evidence to Report Writing before depositing in secure evidence lockers. Evidence is then collected from the secure lockers by the evidence clerk and taken to Evidence Processing room. Report Writing should be adjacent to Evidence Processing or should be close to commanding officers area with proximity to Evidence Processing. • Vehicle entrance and exit to Sallyport should be reversed; prisoners are typically held on the passenger side of the cruisers' back seat. • Animal Control office needs public access, from the exterior or interior. • Revise walk paths on both site plans to correspond to the program arrangement on the plans. Police provided the number of full size lockers and half -size lockers, they are as follows: • Female Lockers; 15 � Y wide and 5 � T wide • Male Lockers; 52 � Y wide and 5 � T wide In order to properly plan for the mechanics area of the garage D &S asked the Department to provide the height from the floor to the top most part of a cruiser sitting on the mechanics lift raised to its highest point. 68 Harrison Avenue Boston MA 02111 6 1 7 4 2 3 1 4 0 0 donhamandsweeney. c om 4 Head Tide Church Rd.

Donham described the results of the structural engineering study for both buildings, a copy of which has been given to M. Barrett. Both buildings are in non - compliance with the seismic requirements of the new Building Code. Retrofitting both buildings with seismic resistant structures is very expensive. To avoid that cost, any addition must have a 3" wide soft joint with the original building and new openings in the masonry walls must be very limited in size. The structural slab in the apparatus room is failing, has sagged and has cracks that extend through the slab. The structural engineer believes it will continue to function at least to mid -2011 and perhaps beyond, but is unwilling to predict when it will fail to the extent of putting the apparatus at risk. He said "something needs to be done soon ". J. Shaw presented two sets of plans for the Fire Station. One is a renovation /addition and the other is a new building. These plans resulted from 2 meetings with the Fire Chief. J. Shaw described the constraints offered by the existing building and the increase in floor area resulting from trying to reuse the building. He also described the significant traffic difficulties with all apparatus trying to exit or enter via Camilla Avenue onto Bedford Street. The Permanent Building Committee offered the following comments; o In the parking table, indicate the number of existing spaces as was done with the Police Station o In the new building design try to avoid the small setbacks at the second floor because of the extra cost o In the new building try to put the stairs in -board so exterior walls are freed up for windows 68 Harrison Avenue 4 Head Tide Church Rd. Boston MA 02111 Post Office Box 265 617 423 1400 Alna ME 04535 donhamandsweeney.com 2 0 7 5 8 6 6 0 0 0 B. Donham presented one set of plans for the Police Station. These plans grew out of extensive consideration by Police Department staff and 2 meetings with them. A copy of the Sixth draft of the Space Needs Program was distributed. The program area has grown from 24,450 SF on 4/13/10 to 28,126 SF in the Sixth Edition. Increases were primarily in the Garage, the Sally -port, the Lobby, and the Lockers [as a result of moving from 30" to 36" lockers and increasing the number of lockers]. The Police Chief said the Dispatch needs to be larger, and secure space, preferably indoors, needs to be provided for 2 emergency generators. He also said he needs a serviceable range that is large enough to train on; the present one is too short and an outdoor range, reproducing real -world conditions, is preferred. The present range is contaminated with lead, he said. The Committee instructed D &S to construct the base building pricing with refurbishment of the present range in the building plus a new indoor /outdoor rang at Hartwell Avenue. An alternate should include a new indoor range at the Police Station. Other comments from the Permanent Building Committee; o Document the gross to net area for each building o Provide cost estimates and elevations at the next meeting on 7/13. The estimates are to include plans with and without seismic upgrades as well as the costs to extend the useful life of both buildings by 10 years. MEP narratives will be needed as well o The 7/13 meeting will include members of the HDC on an informal basis o There will be a special meeting on 7/27 that includes the Capital Expenses Committee and possibly a representative of the Boar of Selectmen -2- Page 1 of 1 Avi Shoss From: DONHAM, BRETT Sent: Tuesday, July 20, 2010 12:13 PM To: Shaw,Jeff Cc: Avi Shoss; Nicholas Derr Subject: Lexington Notes to be circulated to PBC; add your notes added Police Station B. Donham presented the revised plans and the first pass at the elevations for the building. Comments for PBC and HDC members included the following; -all the new construction should read as new; his preference was to not mix the new looking new and the new looking old -the small addition pieces should now be so different from the old, they should incorporate the "feel" or the spirit of the old -the massing looks OK -make things look more like our 2 Belmont Fire stations -show the building in context; show the White Building and Cary Hall -use Sketch -up to show the building in 3 dimensions -show the chimneys and the elevator penthouse -show the radio antenna which might be as tall as 75' -show trees -make the rear garage smaller -the white finish on the new siding is too much of a contrast -the issue is one of proportions and scale Fire Station J. Shaw presented the revised plans for the new Fire Station and the old plans for the renovation /addition option. The meeting confirmed that the renovation /addition option did not make sense. There were very few comments on the elevations. One person suggested replicating the 2 forms of the present apparatus portion of the building and placing the 2 gabled elements side by side. One or two people referred again to the Belmont Fire Stations designs as something that was more appropriate than what was being shown. We were asked to bring photos of the Belmont stations to the next design review meeting. There was consensus that the site was very well located in terms of response time and optimal coverage for the Town. Public Safety Building The study document should list the specific spaces that are redundant if one has two separate buildings, should discuss the location issues for proper response time and should make a guess at the budget and cost difference between a single public safety building and separate Police and Fire Stations. Other Cost estimates are need for the option of short term necessary repairs for both buildings. All cost estimates should reflect an assumed bid date of the Spring of 2012 with an assumption that funds for construction documents would be voted at the Spring Town Meeting in 2011. Unresolved was the question of whether the Spring 2012 Town Meeting would be presented with a cost estimate or with actual bid prices. 9/30/2010 Donham & Sweeney Brett Donham, Principal, AIA A R C H I T E C T S Jeffrey D.

These changes will be incorporated into a revised space needs program and revised plans. Each generation of plans prepared by D &S gets postedat the fire station for review & comments by the officers and fire - fighters. • The department would like to remove some of the existing wood paneling and install it in the new building. • The revised plans should be sent to Chief Middlemiss & Mark Barrett by Friday 6 August. • John Livsey, Town Engineer, is hiring a traffic engineer for another issue in town but will add to his scope to study the access / egress issues at the fire headquarters. • A previous Town Manager approved the access to Neellio's Gourmet Shop to avoid a second cut out on Bedford St. • B. Donham to send M. Barrett a memo on the wetlands issues and request a meeting with Karen Mullins the Town's Planning Director and Conservation Officer. • Three sumps were installed and are tested • Only the sump in the boiler room have ever reported hazardous materials. The belief is that the sump which needs to operate regularly because of a high water table, draws in the contaminated water. • If the basement is abandoned and the sump pump is turned off, then the remediation effort can stop & the equipment & piping can be removed. • There will be a meeting with the PBC on 8/10/10. The agenda is not yet set but is likely to include the following: • Review the revised powerpoint slide show • Review the two programs that show existing spaces, programmed spaces, designed spaces and the difference between programmed and designed spaces • The reasons why the Fire HQ addition/renovation plan option doesn't work, put in writing. 68 Harrison Avenue 4 Head Tide Church Rd.

The table of square footage comparisons prepared by D &S was reviewed. The PBC asked that Yarmouth and Lexington Actual be removed, leaving Lexington Existing, Lexington Programmed, Hudson, and Franklin. The PBC asked that D &S not show the complete list of spaces in the comparison chart, but rather, bunch them into categories. J. Himmel will determine the category groupings and provide that information to B. Donham. B. Donham described the work needed to both buildings in the next 5 to 10 years. The Fire Department apparatus room slab needs to be shored up. D &S doesn't recommend replacing it since the ultimate solution D &S recommends is to replace the building. Other work is identified in the engineering reports and consists of replacing equipment that is or will wear out. M. Barrett reported that the cost identified 2 years ago to replace the slab was $1M. Comments from PBC and Selectman Burnell included; -we need to justify why the size of the two buildings needs to be doubled -don't do any further work on a combined Fire and Police Station [Public Safety Building] -can offices be combined to create more flexible space? -work on only the Fire Station for now, but don't do any more design work -the existing floor area for the Fire station should include the trailer housing the Fire Prevention Bureau -a site meeting with the Selectmen will be scheduled; updated comparative information is needed for that meeting. -D &S to get staffing levels for both stations at the time they opened. 11/17/2010
