CMU block will be ongoing over the next few weeks. The preparation for paint was beginning. On the second floor, the mechanical, electrical, plumbing (MEP) rough was ongoing, followed by installation in the ceiling, water pipe installation, and induct installation. The second floor was slightly behind schedule. Outside of the building, the utilities were ongoing until the weather worsened. Installation of the retaining wall and preparation for the walkways was ongoing. There were photos presented of the interior and exterior of the building. The schedule was adjusted due to the temporary electrical work, and that was moved into April. The substantial completion date was adjusted from March 12 to April 9. Celis requested a single line diagram (in the works) which shows, that solar can be used even when there is a utility company power outage. It was reported that there was an envelope commissioning agent and a building commissioning agent that had been active since the inception of the project. There was also a commissioning agent specific to the BMS control system that would be onboarded soon. It was asked what the status of the switchgear was. It was reported that based on the change order, it was planned to come in on March 24, 2024. Update on Solar Canopy Jeff McElravy reported that at the October 23 Historic District Commission (HDC) meeting, there was a discussion about continuing the presentation due to the late arrival of design documents. It is anticipated to present on November 2nd. The presentation that was prepared for the October meeting was forwarded to everyone. There were suggestions to extend the landscaping behind the enclosure and to get a color sample for the steel. A physical sample will be sent to Mark Barrett and then will be available to any member of HDC. From a design standpoint, the foundation packet was out for pricing. The structural system was being worked through, and it was suggested that the Q-Cells panel could go down to a quarter inch per foot slope. According to Q-Cells, the minimum pitch was three degrees, This, then led to a couple of revisions so that the total slope did not exceed the height limits. Snow loading was discussed. The Q-Cells panel only had a 75 PSF snow loading capacity, and there were significant snow load issues being dealt with. Work was being done so that the snow would not be distributed from the upper canopy down to the lower canopy level panels. If the numbers could not be done appropriately, a different panel would be looked at. On November 2nd, the package will be presented to the HDC. There were comments about landscaping on the other side of the bike path, and the engineers were getting a survey of that area competed. After the survey, additional landscaping would be added. Dan Voss asked if the shade analysis was done. Jeff McElravy reported that it had not been completed yet. The model will be running to see what the impact of shading was. It was asked when an estimate would be received, and a firm date was not known at this time. Mark Barrett reported that the framework pricing would likely be available within the next few weeks. Jon Himmel asked if Q-Cell was a specific manufacturer. Jeff McElravy reported that it was and that it was dependent on the final procurement method. He reported that the mounting system allows for the greatest push and pull loads, and they were trying to maximize the opportunity for the snow load capacity. It was reported that the only changes included additions to landscaping. It was discussed that the final design and pricing information was hoped to be finalized within the next few weeks. Cindy Arens asked for the information to be sent to the Sustainable Lexington Committee, and it was stated that it would be. It was asked if other panels were reviewed before they were re- designed. It was reported that the engineer was reviewing them. Alternate panel options for snow load had been provided, but the panels had a different dimension. The relationship of panels to snow load will be pursued for best fit. It was asked if there was anything significant about funding. It was reported that there was not. Update on Lexington High School Project / Architect Selected Mike Burton provided an update on the Lexington High School Project. He reported that they were in Module 3 after completing the designer selection. Interviews were held on October 3rd, and the Committee chose SMMA to be the designer. It was also the Lexington team’s first-ranked designer. Matthew Rice and Erin Prestileo from SMMA introduced themselves. Matthew Rice shared his screen to present information on SMMA. SMMA is an integrative design firm with 200 employees. The firm designs projects that are responsible, well-crafted, and beautiful. They have designed the new Somerville, Waltham and Winchester high schools. Matthew Rice is the lead project architect, and Brian Black is the lead designer. Community engagement would be a critical component of the project. The school building committee (SBC) would be working with SMMA during the project. Community engagement would continue throughout the project. Stakeholder groups would be asked to provide input. It was suggested that four primary focus groups be created which would interface with the 46 boards, commissions, and committees represented by the stakeholder groups.
