LCP/Pelham Road — (School Committee attended the meetinq on an informal basis), Donna DiNisco & Rick Rice (DiNiscos Designs) Donna presented updates to the LCP design including alternative options discussed at the previous meeting. The goal is to look at it as a comprehensive approach, being mindful of future expansion. • The Preferred Option, (referred to as Option 0), has not changed and shows future expansion for 4 classrooms. This option also addresses Public Safety Requests. Roof top mechanicals are a concern due to the low elevation of the site. This option provides Public Safety vehicles the ability to drive around to the back side of the building. • Option 1 allows for future expansion away from the wetlands moving it to the North side of the property nearest Pelham road thus making the possible expansion less disruptive to the school. The thought is to build now in the Preferred Option expansion area since there is uncertainty of Conservation Regulations 3, 5 or even 10 years from now. This option precludes Public Safety vehicles from driving fully around to the back of the facility. • Option 2 creates a "U" shaped building and provides a courtyard look for the playground area. This design is 850" sq. ft. larger because of the longer corridor at the center of the "U., and reduces future expansion options from 4 classrooms to 2 classrooms. This option provides Public Safety vehicles the ability to drive around to the back side of the building. An all-electric system HVAC would utilize a VRF System & ERU is being recommended. The equipment evaluated is relatively new and currently only available from Daikin. The system design is supported by independent peer review and is appropriate for the building size and spaces. Summit meeting is scheduled for next week to submit the cost findings. Superintendent Czajkowski asked about security. Donna stated the same security protocols like all other elementary schools will be in place. Control of visitors entering, a window in the vestibule for visibility, and a card access system to name a few. 201 BEDFORD STREET• LEXINGTON, MASSACHUSETTS 02420 The director of the preschool program thought the Preferred Option was the better of the options because it grouped classroom at both ends of the building rather than all at one end, While no vote was taken, the School Committee seemed partial to the Preferred Option. 2. Fire Station Project—Jeff McElravy(Tecton Architects). Derek Bride (CES Engineering) Jeff McElravy presentation showed the site plan has not changed, exiting is still the same and Camilla Place parking area is still being proposed on the building side of the drive and is still a work in progress. Floor plan changes showed: • Removable partitions were incorporated to the Day Room, and the bathroom was relocated so it does not open into the Day Room • The second floor was reworked to move all Bunk Rooms along the Camilla Place side, and the office area was reworked. • The front gable area above the juncture between the main administrative wing and the truck bay wing was opened up more to allow for better drainage, and some windows were added to the back side of the building. Jeff stated the plan is still looking to be LEED Silver. Jeff stated some costs have grown related to design and soil concerns. Additionally, additional items have been added to the project that were not there before: the traffic signal needs to be relocated at the apparatus entrance and the OptiCon Traffic System that is currently in the basement needs to be relocated. These cost were not part of the original budget. DPF stated the traffic system was due for replacement and will be bundled with the Fire HQ project. The insulated solid sectional apparatus bay doors shown on the plans have a better lifecycle cost over 25 years versus insulated glass sectional doors. As part of a sustainability and VE discussion, Jeff discussed the cost payback related to changing from the proposed VRF system to a gas fired boiler and air cooled chiller with fan coils. He also suggested that the domestic hot water be upgraded from natural gas to a combination of solar thermal/gas or hybrid heat pump tanks. Temporary Fire HQ site and floor plans were reviewed and new estimates were discussed. 3. Visitors Center Update Don Mills (Mills Whitaker Architects) Don Mills slide presentation showed the adjustment to the east side elevation, and the addition of a limited access service door and windows on the Meriam Street side of the building. Comparisons of the 2016 Conceptual and 2017 Schematic Plans were discussed. Project cost savings can be achieved with material changes. Roof options will also effect costing. DPF stated cost are higher than a year ago. Collaboration is still needed with HDC in design costing. PBC feels a better layout of the cost information is needed for presentation to the Board of Selectmen and the subsequent Summit. Motion to adjourn was made and seconded: Meeting adjourned at 10:30pm. PBC Meeting 09.06.17 2
