Visitor Center Update— Don Millis (Millis Whitaker Architects) Don informed the committee of the latest project status which included the Massachusetts Architectural Access Board (MAAB) approval of the Limited Use/Limited Access Elevator, HDC Hearing scheduled for early January 2019 and 50% CD Pricing for early January 2019. The project budget is $4,575,000 (hard costs & soft costs), and the bidding period is scheduled February— March 2019. Construction is slated for May— March 2019. • Interior layout was reviewed and Historic District Guidelines were discussed. • The use of an electronic display versus a bulletin board, and a kiosk with built in iPads to look up area information were discussed. Content for the electronics would have to be developed. • Exterior wall materials, lighting, roofing materials and colors were discussed. Other exterior components such as bike racks, trash cans, benches & cameras will keep the same style as already seen around town. A proposed gas duct vent on the exterior of the east side of the building for an Energy Recovery Unit (ERU) system was discussed. The gas system would only be used during a power outage and is being proposed to make the building resilient. Gas currently exists on the property. Further discussion is needed regarding use of gas backup with the Board of Selectman. Don discussed how the exhibit fabrications will take place. This is a large part of the project consisting of display cases, cabinets, graphic panels, etc.; with an Exhibit Manufacturer working on this. • Furniture package and ways of procuring FF&E's were discussed. • Construction concerns brought up were the possibility of work at the Battle Green area being done at the same time, and landscaping at the Visitor Center site in the early spring. DPW: Some of the Battle area pathways will be put on hold to allow for matching the walkways with the Visitor Center. 201 BEDFORD STREET 9 LEXINGTON, MASSACHUSETTS 02420 Don: Mentioned some walkway concerns. He asked for documentation on the approved use of aggregate for the walkway. 2. Westview Cemetery Dave: Informed the committee the AD Hoc Crematory Study Committee had their first meeting. They will have their next meeting in Jan. 2019. A meeting with the public will also be scheduled. DPW is still looking to get their building to Spring Town Meeting for approval. • Need to release the architect now to be ready for Town Meeting and to have design development documents by the end of Jan. 2019. PBC: Asked who is doing Justin's estimates. Need to confirm if being done in house or outside. It was stated Justin will be 90% end of February and 95% at the end of March 2019. PBC recommends to proceed with design on current schedule and to meet Spring Town Meeting requirements. Seconded—APPROVED. 3.

Burton reviews budget development slide (side by side) comparison. The slide shows a progression of all iGMP1, 2, 3, and where we came in with Final GMP summary breakdown. 12/13/18 PBC presentation is attached for further details. 5. CM Contingency(w/in GMP): M. Burton reviews CM Contingency slide. The slide includes: Construction (CM) Contingency$1,298,300 Approved: $0 Pending: $263,978 Forecast: $2,571 Balance: $1,031,751 Remaining: 79% 6. Owner Construction Contingency(outside GMP): M. Burton reviews Owner(GMP) Contingency slide. The slide includes: Owner (GMP) Contingency$1,500,000 Approved: $30,246 Pending: $387,780 Forecast: $267,239 Balance: $814,735 Remaining: 54% DiNisco performed additional test pits to determine further soil conditions and exposure. Previously we included $420,000 for final sitework phase unsuitable soil removal. After review of the additional test pits and soil conditions with Welch, phase 2 was revised and assumed to be $350,000. $200,000 is included in the GMP, $150,000 is shown as forecast as indicated above. 7. Value Engineering: M. Burton reviews Value Engineering slide. On 11/8/18, the PBC approved the recommended VE list. Following the PBC Meeting, DPF reviewed with LPS and a couple changes were made. Changes include removing 100% of bird houses, keeping the granite curb, removing tile in stairwell, and removing portals. The project team is recommending taking $175,868 in VE this evening. Up to $150,000 for removal of spray foam is still up for review. D. Perry was not present at the previous PBC meeting. D. Perry still advocates on keeping the spray foam in the building. D, Perry felt the spray insulation would provide a better seal if utilized. His concerns also include proximity to route 128, fumes, gases, and sound. After reviewing the concern with The Green Engineer, DiNisco Design's LEED consultant, it was determined that removing the 1"foam insulation does not affect the performance of the building, that the windows are the weaker link for noise and air infiltrating into the classrooms. DiNisco noted that windows facing 128 are triple pane to help mitigate these issues. D. Perry still feels that doubling up the resistance with both the AVB and the foam would be beneficial. C. Favazzo recommends that the project team reach out to Ned Lyon from SGH, Simpson Gumpertz & Heger, a national engineering firm that design, investigates and rehabilitates structures, building enclosures and materials for a final review of the design, options, and overall recommendation regarding the spray foam. PBC Meeting 12.13.18 3 A motion was made by. J. Himmel and seconded by D. Perry to keep spray foam in the project should SGH affirm that it makes a superior closure system. If found no benefit, then will be removed from the building scope. M. Cronin to circulate information from SGH and a recommendation will be made via email. Vote: All in favor. Motion passes. S. iGMP 3 Approval M. Burton reviews Final GMP handout. The 11x17 document shows the budget broken down by trade within the GMP. C. Favazzo asks whether the GMP amount of$52,973,418 included any Owner Change Orders. M. Burton responds that OCO #1, and #2 have been executed by TOL and were included in forecast slides for contingency but not included in the GMP. All executed Owner Change Orders will raise or lower the agreed upon GMP value of $52,973,418. A motion was made by J. Himmel and seconded by P. Coleman to approve Final GMP 12/13/18 as presented in the amount of$8,765,638 and approve the total GMP value in the amount of $52,973,418. Vote: All in favor: motion passes.
