This includes construction estimate, schedule, and value engineering suggestions. • SBA contracted BR+A to perform a building energy model and Life cycle costing analysis for implementing option 2 and to add higher insulation values in the walls and ceiling. • SBA, BR+A, Shawmut and Town of Lexington met.January 29, 30, February 5, 7, 12 (with Energy and Sustainability Committee members), 13, 26, and March 3 to discuss the options, costs, and schedule impacts of the various scenarios. Findings • The technical analysis found that implementing the project in one phase instead of two should only extend the occupancy date by 4 to 6 weeks, with an opening of the first week in March. • The capital costs to perform the work in two phases increases direct costs approximately $382,000, increasing project costs $484,000. • The existing building has good insulating properties, and adding additional insulation does not improve comfort or enough energy savings to justify the expense. • Replacing the chiller and boiler with more efficient, newer equipment would result in a simple pay back of 27 years LEXINGTON COMMUNITY CENTER — March 5, 2014 Steffian Bradley Architects United States • United Kingdom o Canada • China A&E Design Development & Construction Documents 6.5% $162,000 7.0% $349,000 A&E Bidding & Construction Administration 2.5% $62,000 2.5% $125,000 FF&E $75,000 $125,000 Transition Costs $0 $50,000 Consultants (legal, testing) $10,000 $101000 Commissioning $15,000 $50,000 Total Estimated Soft Cost for Phase 1 , Hard Cost + Soft Cost $3,011,000 $5,945;000 Project Contingency 3.0% $88,000 3.0% $175,000 3,099,000 $6,120,000 Other Considerations Sidewalk Design $20,000 $20,000 Sidewalk Construction $100,000 Additional Fees (Constructability & Carriage House Evaluation) $50,000 $80,000 '.• 1#1 '�. 1 #11 LEXINGTON COMMUNITY CENTER— March 5, 2014 Stettian Bradley Architects United States • United Kingdom • Canada • China LEXINGTON COMMUNITY CENTER — March 5, 2014 Steffian Bradley Architects United States • United Kingdom • Canada • China • Sufficient cooling capacity to cool rooms to 74 degree F, per Town guidelines. • Sufficient heating capacity to heat rooms to 70 degree F, per Town guidelines. • New energy recovery ventilation to provide efficient ventilation for offices and assembly areas as recommended per American Society of Heating, Refrigeration, and Air-conditioning Engineers Standards. • An accessible entrance into the Mansion from the patio, and replacement of the patio stones with an accessibility compliant surface. • A sidewalk extending from Marrett Road to the existing Community Center sidewalk. • Repairs to building envelope including trim/facia/sealants. LEXINGTON COMMUNITY CENTER — March 5, 2014 Steffian Bradley Architects United States • United Kingdom • Canada • China vvnat is roc • Neither a 250 kw generator nor a 450 kw generator (required to maintain environmental conditions) since the installed cost of the small generator exceeds $500,000. • An integrated manual transfer switch with distribution for connection of a portable 250 kw generator, as installed cost exceeded $250,000. • Additional insulation in wall cavities. It was estimated that, due to the amount of wood trim and detailing, opening the walls, replacing the insulation with foam to increase the R value from 19 to 30 would cost over $850,000, but yield only $47/yr in savings. • Similarly, adding additional batt insulation above the ceiling to increase R - value from 30 to 50 would cost approximately $50,000 and yield only $10/yr in savings.

FY15 to FY21 assumes a 3.5% annual increase based on assumed growth in the CPA surcharge of 3.5% annually. 3 Given that these projects constitute preservation of historic resources, the annual debt service payments could be applied to mitigate or meet the 10% threshold required under the CPA, thus precluding the need to setaside a portion or all of the amounts shown in row 7 above. Relatedly, debt service for Wright Farm could be applied to mitigate the 10% threshold for open space shown in row 6 above. 4 Current Estimate of total project cost.
