f Lexington Public Schools Executive Schematic Design Summary Lexington, Massachusetts Report of: Lexington Permanent Building Committee HMFH Architects, Inc. HMFH Architects, Inc. 130 Bishop Allen Drive Cambridge, MA 02139 FAX•617.876.9775 6 1 7 . 4 9 2 . 2 2 0 0 www HMFH . c o m October 16, 1997 Permanent Building Committee Report for the School Renovations and Additions Project The Permanent Building Committee (PBC) was created in 1967 by Town Meeting Bylaw to provide ongoing expertise and expenence in managing town building projects The PBC is charged with managing the design and construction of all town building projects The committee consists of five members appointed by the Town Manager for three year PBC Members terms Members serve as volunteers and are selected for their expertise m managing design and construction projects The committee currently William R Bruckman, Chair includes, 1 engineer, 2 construction managers, a designer, and one open Peter Kelley position As specific projects are brought forward the end user of the Peter D Johnson building has the opportunity to appomt two additional members to Mary Lou Touart represent its interests for that project. For the School Renovations and open position Additions Project the School Committee has appointed two architects with expertise in managing large projects to represent its interests School Committee Appointees The PBC charge includes hiring professional assistants, obtaining bids, and entenng mto contracts on behalf of the town for plans, Jonathan Himmel specifications, and construction In each case the town agency or board Phil Porcelli that owns the building must approve the plans and funding authonzation must be in place In the past, the PBC has overseen the building of Clarke Library Project Appointees Middle School, the town pool complex, the 1975 addition to Cary Memonal Library, the 1985 additions and renovations to the schools, the Jay Lucker renovation of the police station, and the reopening of Hastings The PBC Walter Pierce reports directly to the Town Manager and provides penodic reports to the Selectmen and Town Meeting as required for individual projects School Renovations and Additions Project Goals • Develop cost effective plans • Address public safety issues associated with parking, student drop-off, and extenor lighting. • Develop project scope that meets requirements for 59% state reimbursement Meet building codes to comply with handicap access, fire protection requirements, earthquake design, etc Extend buildmg life 20 years Reflect School Committee Policy Obtam funding authonzation from the town • Address deferred maintenance and renewal of roofs, wmdows, heating, electrical, plumbing, road, and parkmg systems • Provide additions as required to meet 25% enrollment growth over the next 10 years while maintaining current class sizes • Reclaim dedicated space at the elementary schools for art rooms, music rooms, computer rooms, and special education • Do not provide dedicated space for foreign language, Lextended day, or science at the elementary schools • Equivalent (equal facilities) between the six elementary and two middle schools School Renovation and Addition Program Goals The process of developing the goals for this project has been ongoing smce 1993 At that time the school committee and selectmen authorized the Archetype study to generate cost estimates for upgradmg school and town buildings to current standards The school buildings range in age from 24 to 49 years old and the electncal, heatmg, plumbing, and fire safety systems have reached the point where they must be replaced or repaired. The Archetype study recommended spending 66 million dollars on the school buildings to deal with deferred mamtenance and renewal of flooring, roofs, doors, windows, heating, electrical, and plumbing systems for the school buildings In 1995, the Building Fmance Committee (BFC) cut the Archetype plan to 34 million dollars by proposing to repair only those systems that protected the buildings from further damage As part of their plan the BFC recommended that a space utilization study be undertaken to deal with enrollment growth at the schools In the summer of 1996, the Permanent Building Committee (PBC) hired the architectural firm, HMFH, to carry out the space utilization study As part of this study the School Committee held public meetings to review and define their policies concerning class size, enrollments, and dedicated space for art, music, special education, foreign language, Lextended day, and computer labs With these revised policy guidelines m place, the PBC directed the efforts of HMFH to develop cost effective plans for the additions needed to meet growing enrollments and the educational program This study was completed m January and led to a Town Meeting appropriation of 2 4 million dollars to develop comprehensive plans and cost estimates for the entire project mcludmg renovations During development of these plans, HMFH emphasized that in order to qualify for state reimbursement the plans must be cost effective, address school committee policy, meet building codes, extend the useful life of the buildmgs for 20 years, address enrollments for the next 10 years, and have funding reimbursement reduces the direct cost of the project to the town by 59% authorization from the town State reimbursement reduces the direct cost of the nroiect to the town by 59%.As such, the PBC directed HMFH to develop plans that meet the requirements for state reimbursement. The PBC also asked HMFH to address public safety issues associated with parking, traffic flow, and exterior lighting because the state will pay 59% of these costs as well The primary goal of everyone involved in this project has been to develop a cost effective long range plan that meets the need to renew the buildings, provides adequate facilities for the schools, and fits within the financial plans of the town as a whole Dunng the development of the plans, the PBC (with school committee participation) has held over 50 public meetmgs to review and optimize the planned renovations and additions The majority of the cost of the proposed project (roughly 80%) is to renew the buildmgs, roads, and parking. The remaining 20% of the cost addresses increased enrollments and accomodates the educational program. Major Cost Cuts to Improve Cost Effectiveness • Renovate existing schools and retain existing classroom sizes • Many small decisions reduced project costs - use minimum size for new classrooms - elimmate and reduce, where possible,hallways in additions - reduce landscape plantings by 50% - use asphalt and/or precast curb instead of granite curbing - use concrete mstead of stone walkways - minimize replacement of internal plumbing - refurbish instead of replace univents - reduce built-in storage cabinets - do not enclose walkways at high school - keep existing windows as much as practical • Some decisions reduce future mamtenance costs but add cost to the project - cover soffits and facias with aluminum instead of painting - install playground safety surface instead of re-mulching every year Developing Cost Effective Plans to Meet the Project Goals The first cost estimate to meet the project goals was roughly 200 million dollars This plan increased the size of existing classrooms to meet state guidelines and provided smaller elementary and middle schools that would encourage cohesive neighborhoods and provide a better learning environment The plan called for eight, 350 to 400 student elementary schools and three, 500 to 600 student middle schools To mcrease the size of existing classrooms, walls had to be torn down and rebuilt in the elementary and middle schools The state guidelines for classroom size allow a range from 900 to 1100 square feet. Almost all of the existmg rooms at the middle schools and many of the existing rooms at the elementary schools are less than 900 square feet. By meeting with the state Department of Education, the Architects established that the state would allow existing rooms to remain their existing size if they came close to their guidelines ( i e rooms greater than 800 square feet) The School Committee voted to sacnfice the educational and neighborhood benefits of smaller schools and maintain existmg classroom walls as much as the state would allow These two decisions cut the project from 200 to 140 million dollars Unfortunately, there were no more large reductions m project scope and cost that would not be in direct conflict with the project goals However, by working with the architects, the Department of Education, and the school department, the PBC was able to reduce the project by another 30 million to the 110 million dollar range To do this, hundreds of decisions were made to determine whether a particular floor should be replaced or not and what types of matenals should be used to use to replace the floor, etc Part of the decision making process mcluded the effect of choices on future maintenance costs There were instances where costs were added to the current project so that future maintenance costs would be reduced. An example of this was the PBC's decision to recommend covenng the extenor soffits and facias with aluminum instead of just painting them Some of the major items that reduced the project cost consist of: creating all buildmg additions with rooms sizes at the minimum of the state guidelines, eliminating and reducing hallways m the additions wherever possible, using asphalt and/or precast concrete instead of new granite curbs, reducmg all landscape plantings by 50%, ehmmatmg imgation, seeding instead of using sod, keeping existmg windows at Bndge and Bowman, and minimizing the replacement of piping, etc The net result is a project that meets the project goals at minimum cost to the taxpayer To reduce the cost of the project further will require sacnficmg the project goals School Renovations and Additions Project Cost (million of 1997 dollars) Cost Element Gross Town Cost Cost Enrollments 14.0 6.3 Policy 5.5 2.4 Special Education 2.7 Art/Music 1 9 Computer Rooms 0.9 Deferred maintenance/renewal 66.4 29.8 BFC deferred maint./renewal 31 0 State req'd. add. deferred maint./renewal 29 4 PBC deferred maint./renewal 6.0 Traffic Safety/Site 12.3 5.5 Parking/roads/drainage 11 1 Lighting and landscaping 1.2 Total 98.2 44.0 Traffic Safety/Site Enrollments 13% 14% Policy C�..y'1� rtyy •. 6% Deferred maintenance/renewal 87% Project Costs The total estimated cost of the project m 1997 dollars is 98.2 million dollars Of this the town will finance 44 0 million and the state will finance 54.2 million. The project costs can be divided into four major categones. enrollment driven costs at 14 0 million, School Committee policy driven costs at 5 5 million, deferred maintenance/ building system renewal costs at 66 4 million, and public safety/site costs at 12 3 million. The costs associated with enrollment driven and School Committee policy both translate into requirements for space within the schools. The approximate change m cost associated with changing a particular school committee policy or enrollment change can be calculated by multiplying the additional space requirements (m square feet) by the amount allotted by the State per square foot for the type of school. For example, adding a room for Lextended day at each of the elementary schools would increase the required space by 7200 square feet. The allowable amount for elementary schools is $153 oer square foot which would have increased the project cost by approximately $1,101,600 In a similar fashion, elum hating the 6000 square feet for computer rooms at the elementary schools would decrease the project cost by approximately $918,000 The School Committee used this type of analysis as part of their policy making process The town costs associated with deferred maintenance and building system renewal can be subdivided into three categories 1) the cost required to protect the buildings (the BFC recommendations); 2) system renewals/code compliance (require for state reimbursement) and 3) items recommended by the Permanent Building Committee that are prudent to do as part of the project, but are not required to qualify for state reimbursement. The system renewal and code compliance required by the state extend the life of the buildings' heatmg, electrical, and plumbing systems for 20 years and update the buildings to meet code requirements for earthquake protection, the Americans with Disablities Act, health and safety requirements and fire protection. The PBC recommended items consist of replacement of some older window systems, replacement of all asbestos containing floors, and replacement of some items to reduce future maintenance costs. The costs associated with rebuilding the sites are subdivided into two categones, parking, traffic flow, and drainage, and lighting and landscapmg. None of the site work is required to qualify for state reimbursement. However, the PBC strongly recommends that this work be included to solve traffic safety problems and allow reconstruction of the roads and parking lots with the advantage of state reimbursement. The parking and roads will have to be reconstructed within the next ten years and the town will have to pay the full cost if the site w; of included in the project. Alternatives to Initially Proposed One-Phase Project: • Review and accept applicable deductions to reduce overall cost • Look at building a new Diamond Middle School : Determine impact regarding use of existing school while new being built Review opportunity for tying addition into main spaces (i.e. auditorium) and maintaining parts of existing school for future non-academic use. After further investigation, it was determined that there was not enough land to accomodate all needs (such as appropriate playing fields) to accomodate the concept. • Discuss increasing size of addition to Diamond and renovating Clark with no addition: Potential for increasing enrollment to Diamond significantly • Re-evaluate impact of dividing the project into two phases • Sacrifice project goals established by the School Committee • Increase class size to reduce new construction requirements • Eliminate specialized spaces such as music rooms, art rooms, etc. • Yearly appropriations for Capital Improvements of$5 million for the foreseeable future 4 Alternatives to Proposed Project Lexington's school buildings have reached an age where they require major renovations of all building systems and the growth in the school population has created needs for more space at the elementary, middle, and high schools Any alternative project will have to sacnfice one or more of the project goals Much effort and thought by many town boards and concerned citizens has gone mto establishing these goals The Permanent Building Committee believes these goals represent the best interest of the town and we do not recommend sacnficing any of the project goals However, the PBC has identified 6 2 million dollars of possible cuts These cuts diminish the quality of the project in significant ways but they do not sacnfice the goals of the project. The cuts include many individual items like continue the use of oil-fired boilers instead of switching to gas-fired boilers or refinish existing bookcase instead of replacing them Each individual cut is identified in the detailed cost estimate for the project. The Permanent Building Committee looks forward to public debate to help determine which cuts should be taken Dividing the project into multiple smaller projects or delaying portions of it simply defers the work that needs to be done to renew the buildings For instance if we chose to only do the middle schools at this time, the needs at the elementary and high schools would not go away Ultimately the overall project cost would increase because there are certain economies that anse by combining the projects For example, design costs vary from roughly 13 per cent for a relatively small project to as low as 8 per cent for a very large project. Larger projects also attract larger more qualified contractors, so that the chance of getting a good contractor for a larger project is better Delaying does allow more time for making decisions, but it won't improve the overall cost. Undertaking a smaller project that doesn't meet the requirements for state reimbusement is not an attractive option The Building Finance Committee report looked at the cost of a project that would essentially protect the buildings, but would not address school committee policy, growing enrollments, building system renewal or reconstruction of the parking and roads The cost to the town of a project with the scope of work presented in the BFC report including all design and engineering expenses is roughly 31 million in 1997 dollars The town would eventually have to complete all work that was left undone without the benefit of state reimbursement The Permanent Building Committee, the Capital Expenditures Committee, and the Appropriations Committee all support putting the proposed project forward to public debate, town meeting, and ultimately a debt exclusion ovemde vote Specific information is contained in this report that will allow everyone to understand the project and pass judgment on its value to the town is Or � 2" w .coo e''' coo i "' e-" o cl !%t „ 0,0 E 0 ro OA O ,3:1 941 .2 CD w to-A '> w CoD. , (I) r+ % 0. o ° fi3 �` o. •e G c2,, � i 2. .. a' 0 n-cs o oD coco vCD 2 2 '' 9s i co ovaQ 0 v <3. ., o o s 0 e. - .-o +, et co y, 0 CD ..ue+ 0 to OA ,t 0 u, O " ° i 5 . ,* r ` n° ' O ° r ,* (D ?

Fri e/5/97 Progress Rolled Up Task 1111.111111111 Milestone • Rolled Up Milestone /\ Schedule The next step for this project is to gam funding approval from the town this fall If funding is approved construction documents would be generated for each of the schools during the first six months of 1998 The construction documents will be submitted to the State for approval for reimbursement on a school-by-school basis begmnmg with Diamond and Clarke m March of 1998 and ending with Bowman and Fiske in June of 1998 After submittal, approval from the State takes 2 to 4 weeks Once approval is m place actual construction can begin. The project construction schedule has to mmmvze the level of inconvenience, meet the space needs for growing enrollments, and allow efficient execution of the project even though the buildings are occupied during much of the construction In general, additions will be completed before renovations start so that the new space can be used during renovation. Construction at each school or building will begin in the spnng and carry through three summers and two complete school years This allows three full summers of construction on an unoccupied building. Enrollment growth is most pressmg at the middle schools and is expected to be 10% over the next three years. The middle schools are currently at capacity The shop and home economics areas were already converted to regular classrooms in 1996 To meet the enrollment increase in the middle schools the Clarke and Diamond projects will start in Spring of 1998 and finish m Fall of 2000 At the high school the roofs on buildings G, H, and J require replacement today Needs for other major renovations are imminent and the plan calls for the start of the high school project in the Summer of 1998 just after the middle school projects begin. Work on the high school will be complete m the Fall of 2000 At the elementary schools enrollments have begun to level off and the immediate needs are being met by using portable classrooms and the temporary use of art rooms, music rooms, and computer rooms as regular classrooms. The construction project will restore art, music, and computer rooms to all the elementary schools and eliminate the need for portable classrooms The six elementary schools will be done in pairs starting in the Sprang of 2000 Construction is planned at Hannington and Hastings from Spring of 2000 to Fall of 2002, at Bndge and Bowman from Spring of 2002 to Fall of 2004, and at Estabrook and Fiske from Spnng of 2004 and to Fall of 2006 There is no doubt that students, teachers, parents, and townspeople will all expenence inconvenience during construction. The first pnonty during all phases of the project will be public safety Throughout the project the PBC and the project team will publicly address concerns of citizens, teachers, students, and parents involving traffic, noise, dirt, and safety as they anse Homeowner Tax Bill Impact for Phase 1 Including all interest expense Peak Year Average Total Tax $ $ per Year $ per Year for Project over 28 yrs $200,000 Home 157 85 2458 $300,000 Home 235 127 3686 $400,000 Home 314 169 6144 $500,000 Home 392 212 7373 Yearly Homeowner Tax Bill Impact for Phase 1 400 •, • 350 N 300 - .. ` N .. , MI / I >. 250 , , I' , ,� a 200 - ' 1 i O ` — —$200,000 Home 5 150 ' ...� 1 ` . a o i, .00.*�. ` "'x"$300,000 Home 100 : / �. - - - $400,000 Home 50 r 7 ..*•,-• _, — -- — $500,000 Home • 0 1995 2000 2005 2010 2015 2020 2025 2030 Year Phase 1 Project Financing Phase 1 Schools Project Cost Net to Town Lexington High 13,232,922 Diamond Middle School 6,659,654 Clarke Middle School 5,501,359 Harrington Elementary School 3,248,165 Phase 1 Total I 28,642,100 Phase 1 of the proposed project would be financed via a debt exclusion override not from the tax levy The tax receipts authonzed by a debt exclusion could not be used for purposes other than the proposed building project. The project represents a major capital investment for the town that extends the useful life of the school buildings for more than 20 years The cost of the project is not a normal yearly operating expense and needs to be outside the proposition 2 5 limit, so that operating budgets will have adequate funding. In order to spread the cost over the useful life of the buildings, a series of 20-year bonds would be used to fund the project. With this approach, future citizens who benefit from the project will also have the opportunity to share the cost of the project. Short term financing will be used initially pending the start of reimbursement payments from the state During this penod the town enjoys the advantage of earning mterest on the borrowed money until it is spent. As parts of the project become complete the short term bonds will be converted to 20 year bonds. Shortly thereafter reimbursement payments from the state will start. The state payments will come in twenty equal payments based on 59% of the total project cost including mterest expenses The principle of each bond will be paid in twenty equal yearly payments with a yearly interest payment based on the outstanding principle This results m a variable payment rather than the level payment that most people are used to with their home mortgages. By using equal principle payments the town reduces its interest expense and protects its credit rating. The net result is that the debt exclusion must provide different levels of funding each year This funding reaches a peak of 3 1 million dollars in 2006 assuming long term mterest rates of 5% and short term rates of 4%. The average yearly funding over the life of the bonds is 1 7 million dollars per year All of this translates mto a yearly peak tax impact of$235 on a $300,000 house in 2006 and an average tax payment over the life of the bonding of$127 per year Project Management Selectmen Capital and School Voters Appropriations Committee Committees Town Meeting Richard White Jeffrey Young Town School Manager Superintendent John Ryan Permanent John Moynihan Town Director Building School Dept. of Finance Committee Facilities Dir Financial Fay DeAvignon Management 4 i Owner's Staff Representative Clerk of the Works and Consultants Project Management Management of a project of this scope will require hinng professional construction management staff to manage the design and construction and financial management staff to properly execute the bonding and investment of the funds John Ryan, the Town's chief financial officer, will direct the financial management and needs to retain additional part time financial management and clerk services for this purpose For construction management, the PBC has retained an Owner's Representative who will be responsible for day-to-day direction of the Architects, Engineers, and Contractors The Owner's Representative is an expenenced manager of large construction projects who will become a full time employee as construction progresses The Owner's Representative will hire consultants and Clerks-of-the-Works as necessary to venfy that the plans and construction are properly executed. Clerks-of-the- works are expenenced construction professionals who work at the construction site and inspect the Contractor's work pnor to approving payment for the work. The PBC anticipates that 3 Clerk-of-the-Works will be required at the peak of the project The Owner's Representative reports to the PBC on a weekly basis and reports directly to John Moynihan, the School Department Facilities Director on a daily basis The costs associated with these service qualify for state reimbursement and are included in the overall project cost. To be sure that the project stays on track the PBC proposes quarterly project reviews where the Owner's Representative, along with the PBC and School Department will present the project status to the Selectmen, the School Committee, the Capital Expenditures Committee, and the Appropnations Committee In addition to these meetings, the project will be presented to town meeting annually to show the current status of construction and spending plans The plans will be updated as required to reflect changes m enrollments, town finances, etc as required Description of Categories Used to Summarize Construction and Project Costs Site Costs: Consists of all work done to prepare each site for new construction, new utilities, relocated parking areas and improvements to existing paved areas and walkways In addition, this category also includes minimal new/relocated landscaping, site lighting, and playground improvements Renovations: This category covers all work necessary within the confines of the existing building/s to accommodate programmatic changes, building code compliance/Americans with Disabilities Act regulations deferred maintenance and the like Also included here is the work necessary to repair and/or replace items on the exterior envelope such as roofs, masonry, windows, etc Additions: All construction costs associated with the new additions required to accommodate increased enrollment and programmatic needs. Design Contingency: An allocated sum of money (generally calculated as a percentage of the proposed construction costs)to be used to offset costs incurred by ongoing refinement of the design process and the details generated in the construction document phase In this project, a contingency of 5% forrenovations/additions and 10% for sitework has been held. General Contractor Overhead & Profit: Those costs incurred by the General Contractor dunng the construction process. This category includes items such as G C staff salanes/benefits, on-site trailers, utility costs directly related to construction, cleaning, protection, permits and insurances Profit is also included in this percentage. Design. Furnishings.

Additions will be made to the campus in three different areas. First, a new Library Reading Room is added to the main building, (G) Along with support spaces located in the existing G Building,this will establish a new centrally located Library/Media Center Second,a row of undersized Science Labs is expanded by a small addition to fill out an overhang at the Science Building. Third, an addition is built at existing Receiving to expand receiving, storage,and custodian facilities. Traffic flow on the site is also significantly revised. A new main entrance to the campus is established off Worthen Road. This will create a new image for the school as well as clarifying and simplifying circulation, security, and other functional issues related to access to the High School. Regular vehicle circulation is removed from the central courtyard in order to reinforce and improve the pedestrian environment in this space. Program. Parking: The Worthen Road parking lot is reconfigured for student parking. It will include a new vehicle access directly from the street. Independent loops are established for safe and convenient parent and bus drop-off The rear lot off Waltham Street is used for staff parking and service,with access from this area to Muzzey Street for emergency vehicles only This will improve control over auto circulation through the site.It will also serve to emphasize the quieter, more pedestrian orientation of the Muzzey Street access to the school. Vehicle access from Muzzey Street will be limited to a drop-off loop behind the ABC Building for high school students and LABB vans. The total amount of parking on the campus is increased in this scheme. Main Entrance: A new main entrance for the High School is established off Worthen Road. A new central Administration Cluster for the Principal is placed in the G Building facing Worthen with clear view of the entrance and parking areas. Bus and parent drop-off are being designed into this area to give Administration a clear view of the comings and goings related to this. There are two separate entrances planned for this location. One will serve as the main entrance to the school,adjacent to Administration and just in front of the new Library/Media Center This move will reinforce the corridor through here as the"Mainstreet"of the campus,linking the Library with Administration,the Gym and the Auditorium. The second entrance is for athletics and opens onto the Gym and into a newly reconfigured Locker/Shower complex and Fitness Center New canopies will provide shelter for the two entrances as well as serving to unify and improve this face of the high school. This area, which could currently be considered the back of the school, will become the new front image of the updated campus. Department Reconfiguration. Departments and room layouts are being reconfigured throughout the campus in order to de-emphasize the current house system. Flow through the buildings is reestablished on both floors to encourage intercommunication between faculty and students in all disciplines. Departmental Clusters are distributed around the campus and provide office space,resource area,and storage space for each department. Lexington Public Schools September 2, 1997 Library/Media Center. The library will be moved out of the Science Building to provide space for the expanding Science Department and to provide a more central location which will serve all students and faculty better It will move into an important location opposite the main entrance which is appropriate for a space so important as the heart of the high school campus. The required support spaces will occupy the existing spaces along the old G Building corridor, vbihile the new Reading Room breaks out of this space into the courtyard. This will provide a pleasant environment for access to and use of the multi-media resources that the Library will contain, while making efficient use of existing spaces. Commons Wing: The area of the main building which formerly contained Industrial Arts and the Cafeteria will be reorganized and expanded. This area will contain two open Commons areas to function as cafeterias and other purposes,Music, and a new receiving/storage area. The existing Kitchen will remain as it is. The loading area off the parking lot is reconfigured to serve this area adequately Commons will open to outdoor eating patios in good weather One of these faces the central courtyard. The other faces the southern courtyard which will also include the new Library Reading Room addition. Science: The Science Building is renovated in order to provide additional Science Labs. Existing,undersized Labs on the First Floor are expanded to be equal to those above. The existing tiered Lecture Hall is not well utilized and will be demolished to make room for Science Resource and Project Rooms, an office and a significant amount of new storage space. Physical Education. The current locker/shower area will undergo a significant reconfiguration in order to accommodate a new Fitness Center and improved team and training facilities. Under utilized shower facilities will be reduced in size and new offices for the Athletic Director will be built at the new Athletic Entrance. Coach and teacher offices will be improved. Fine Arts: New music facilities for band, and orchestra will be created in the former Industrial Arts Wing. Much needed storage for music equipment and materials will be added to this area. This will make good use of the high ceilings and relative acoustic isolation of this area. The current Drama Room on the second floor above the present Administration space will be expanded to better serve its use. The Art Department will get a new CADD Drafting Room. All mechanical systems will be renovated.A new automatic sprinkler system will be installed.Existing plumbing fixtures will be replaced where necessary The domestic water services will be replaced due to the age and poor condition of the existing services.The HVAC systems in the school are 42,40,and 33 years old with the exception of the new 1 year old steam boiler plant in the original Main building.Most of the systems will be replaced with the exception of unit ventilators-which will be refurbished,and ductwork-which will be reused wherever possible-all existing ductwork will be cleaned.The existing oil fuel system will be converted to a gas fuel system.All motor-driven equipment will be replaced.All steam valves will be replaced.A new temperature control system will be installed.The boilers and associated equipment serving the 1962 additions will be replaced.Steam and condensate piping will be tested and replaced where required. Electrical systems will be completely updated and will provide an expansion of educational technology of the recently installed data network.New energy efficient lighting will improve light quality New emergency lighting will provide proper illumination of all egress and assembly areas for safe evacuation. Power will be upgraded to accommodate the demands of a modern educational environment. HMFH Archit+cta Lexington High School Parking Data i I ExistifR Bats' 3'3 Total !

Site area. 20 acres Building area. 147,297 gsf(126,832 gsf existing+20,465 gsf new addition) Current enrollment 1 680 students Projected design capacity 800 students A compact three story addition will be constructed at the main entrance to the Clarke School in order to accommodate the increased student population. It will also allow space within the building to reconfigure the small triangular classrooms that characterize the building. This addition will establish a new entrance image for the project. It will also provide improved vertical circulation and a sense of orientation for this multilevel hillside school. The triangular classrooms with portable partitions are reconfigured into larger,more useful rectangular rooms with fixed partitions. Program The proposed plan includes 7 team clusters for major subjects,shared by the 9 teams,9 Science Labs,5 Foreign Language Labs,2 Art Rooms with kiln,storage for projects and supplies, 2 Music Rooms(a Music Classroom and an Orchestra)with Practice Rooms and instrumental storage,2 Team Project Rooms,4 Computer Labs, including the CADD Lab, with storage,3 Spec.Ed.Classrooms,a Learning Center,5 Resource Rooms,2 Speech and Language Rooms and a Conference Room, Spec. Ed. Center Offices,Health Suite,Cafeteria,Auditorium and 3 Gym Stations, including a Fitness Room. The Library will be reconfigured to provide adequate space for a reference room,class spaces,conference,office,storage and A/V room. A Guidance Suite will include 3 guidance counselors' and one psychologist office,as well as a conference room. The Administration Suite will be reconfigured and renovated. The teachers support spaces will provide adequate office, work and storage space,as well as a teachers' room and dining area. Renovations: Traffic organization will be improved. Bus and parent drop-off will be reconfigured and the number of parking spaces will be increased. Existing roadways will be repaired and resurfaced. Site lighting will be improved. All existing windows will be replaced by new aluminum windows. All exterior steel doors will be replaced. All exterior louvers will be replaced. All interior walls will be painted. Door openings and clearances will be modified to comply with ADA requirements. All doors to remain will be refinished. Existing tectum panels will be removed and new acoustic material will be installed where required. Existing vinyl asbestos tile will be abated. All classrooms and corridor will receive new VCT New carpet will be installed in Administration,Music Room,Orchestra Room,Spec.Ed.Rooms,all Computer Lab areas, including the CADD Lab,teachers' spaces,and the Library New resilient athletic surfacing will be installed in the Gymnasium. Operable partition in Gymnasium will be replaced by Vinyl net partition. The wood stage floor will be refinished and made accessible by a new wheelchair lift. New epoxy flooring will be installed in the kitchen. All toilets will be ADA accessible and will receive new ceramic tile flooring. All acoustic ceiling tile will be replaced to accommodate the sprinkler system and other work.Existing chalk/tack boards will be repaired. New vertical blinds will be installed. New projection screens will be installed. Extensively renovated classrooms will receive limited amount of new casework. Casework in existing classrooms to remain and in Science Labs will be repaired and refinished. Asbestos containing materials will be abated and removed. A new passenger elevator will be provided in the addition to serve the school from a more central location. Auditorium seats will be re-upholstered wherever necessary All lockers in corridors and locker rooms will be painted. All mechanical systems will be renovated and the building converted from electric to gas fired heat. A new automatic wet suppression sprinkler system will be installed. Existing plumbing fixtures will be replaced where necessary to meet energy codes and ADA requirements. Faucets and flush valves will be replaced. The main runs of cast iron sanitary and storm piping below the building,are anticipated to remain. A new,gas-fired,two-unit domestic water heating plant will be installed. All valves in the domestic water piping systems will be replaced. The existing dedicated Science acid waste system which runs to an outside manhole, is anticipated to remain. However,new pH monitoring and control equipment will be installed. The HVAC systems in the school are either three years or twenty five years old. Most of the system will be replaced or modified with exception of the classroom unit ventilators(heat pumps)and the general duct work system. These heat-pump units will be converted(by replacing the reversing valve to an expansion valve for cooling only and replacing the electric heating coils with hydronic heating coils)to reduce heating costs. A central boiler system and a hydronic piping system will be introduced. This plant would have the biggest impact on energy usage of the building. Replacing costly electric heat with natural gas fired hydronic system is a large capitol investment yet can triple the heating system efficiency In general, all motor dnven equipment will be replaced excluding the new classroom unit ventilators;but including exhaust fans,unit heaters and air handling units. These systems are all beyond their normal life expectancy Renovated rooms would be looked at to see if any of the existing equipment can be reused. New rooftop and split-system(DX electric cooling and hydronic heating)unit ventilator units will be used for the redesigned spaces and new addition. Existing ductwork which can be reused will be cleaned before it is reused. The existing electrical system is 26 years old. The existing distribution equipment is at its life expectancy however it is in good condition and will be selectively maintained. The system will be modified to satisfy renovations of building and mechanical systems. The fire alarm system will be replaced to meet the requirements of today's ADA and fire protection codes. Communication and security demands of today make essential the replacement or installation of telephone, sound/intercom and paging,video CATV,clock program and security systems. The newly installed data system will be expanded and altered to accommodate the new addition and the reconfigured classrooms. Energy demands regarding lighting have been addressed as a result of a Utility Co retrofit of lamps and ballasts. These light fixtures will be cleaned and relamped as ceiling work is done to install sprinklers. Power will be upgraded to accommodate the demands of a modern educational environment. 1 Clarke Middle School Parking Data w Proonid b.rsMot Toa. 414 i .,. \ ►AMINO ARG. 10 SAYS 5 ENTRY LION ' 1 J)J !N.C.ACCEHISLL'SIACCI 7-� a tWST*NO EVERGREEN THEE,TYP J 4 leo, ••••• PARKINS ARG. 14 SAYS •0 ,, MIMS CANOPY TREE.TYP ..

The central boilers and associated equipment will be replaced. The two firetube steam boilers will be replaced with two(either cast iron sectional or fire tube) steam boilers. All steam traps and valves will be replaced. Steam supply and condensate return piping will be cut to have it inspected for corrosion levels. The boilers will be sized to accommodate the existing school and the new addition and expanded Library New hot water piping circuits will need to route from the Boiler Room to these additions. Steam to water converters(located in the Boiler Room)will be used to make hot water to heat the new spaces. This system will also be used to heat the expanded Library, replacing the existing hydronic system. The HVAC boilers will be natural gas fired and the existing#4 oil storage and transport equipment will be removed. Most motor dnven equipment will be replaced including exhaust fans,unit heaters and air handling units. These systems are all beyond their normal life expectancy Newer systems would have higher efficiency premium motors along with new controls that will increase the comfort level of the building throughout.The new addition(s) will be served by hot water classroom unit ventilators located at the perimeter Rooftop units with electrical air conditioning will serve the Administration Area and other interior spaces. All Electrical systems will be completely replaced. The newly installed data network system and video CATV will be expanded to accommodate the additional classrooms,Computer Labs and CADD Drafting.
