7:00 -The meeting was called to order—Cafeteria
1. 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.
