Hastings Update— Mike Burton (Dore & Whittier), Donna DiNisco (DiNisco Design (See Attached) 2. LCP Project Update —Donna DiNisco (DiNisco Design) Donna DiNisco reviewed a slide presentation which updated the committee on site plan, interior plans, and specific sustainable goals for the project. Sustainable Goals • All Electric Building • VRF System & ERU supported by Peer Review. The VRF system is appropriate for building size and spaces. • Energy use savings over code at 48.9% • Greenhouse gas emission reduction is over code at 37.9%. • Energy Goal exceeds Stretch Energy Code by 30% • CO2 levels: System design optimizes carbon Dioxide dilution through Fresh air distribution, expects a range between 720-810 ppm. Various Rooftop Solar Options were reviewed, along with a Parking Lot Study for the use of Solar Canopies. • Solar design maximizes roof space. • Discussion on solar canopies and timing of solar installation vs. Building and site construction. Discuss running conduits to traffic islands during project in anticipation of solar canopies. Solar on the roof and canopy's could net up to 322,000/kwh/yr +/- 130,000 consumption, nets 190,000/kwh production. Some discussion followed on the use or application of excess generated solar. 4. PBC Co-Chair Discussion There was some discussion over the need to appoint a new co-chair to the committee. It was elected to carry this discussion to the next meeting. Motion to adjourn was made and seconded: Meeting adjourned at 9:10pm.

D&W MHES PBC MEETING M. Burton from DWMP discusses the 12-14-17 presentation that is being shown to the PBC. The agenda includes: Design Development Cost Reconciliation, Value Engineering, Proprietary Letter Approval, PBC Approve VE/Total Project Budget. 2. DD COST RECONCILATION M. Burton discusses the Reconciliation Recap slide. Reconciliation was held w/TOL, DiNisco, Walsh, and DWMP on 12/11/17 at WBI's office. The team received estimates from Walsh Brothers and AM Fogherty which were reconciled to a 1% variance. AM Fogarty's reconciled estimate will be used for the DD Submission to the MSBA on 1/18/2018. The next slide presented shows the Reconciled budget compared to the MSBA 3011 form. The bottom of the slide and sheet indicates that from the SD estimate to the Reconciled DD estimate, the delta is$1,270,390.00. The target for direct construction cost is$41,215,000, which equals $1.1 million in value engineering options that need to be taken to maintain the budget. RS 3. VALUE ENGINEERING RECAP/PROCESS P��c:7a�II-E MA Ac:;;�:: AItC,�ll'I"V?C"T"S M. Burton discusses the Value Engineering Recap/Process slide. On 11/9/17, the PBC reviewed Ncvburvpor, ,MA COW the VE log. The PBC reviewed ROMS (rough order of magnitude) and confirmed which items 978.499� '29911 ph °```'�"�'�`�"��"� 978.499.2944 d ix www,doreo dwhirrier.com should be estimated. The PBC requested other TOL feedback on the VE items. This included the school department(superintendent, principal, and a school committee member rep), and DPF (Mike Cronin). The VE log was updated with the comments from these departments. The PBC were handed a new updated VE log to review tonight. On 12/19/17 there will be a School Committee meeting held to review the log for the first time, and a meeting on 12/21/17 with a joint meeting between the PBC and SC to review together. J. Himmel a PBC member, stated that he understood according to Town of Lexington bi-laws, that ultimately the PBC and SC will make a recommendation to the Town Manager, Carl Valente, who makes final decisions/approval. 6. PROPRIETARY LETTER APPROVAL M. Burton discusses proprietary items. The project team discussed proprietary items with the TOL. From the discussions, it was determined that the TOL is using specific software that all tie into their system. This includes ExacVision Software (building management system software), Vivotec Security Cameras (standard cameras used across the district), DSX software, controls, and equipment(access control system used in all buildings), Sargent DG1 TE keyway (standard keying system used across district), LCN door closure unit, Von Duprin door exit devices, Aiphone A(entry door communication devices), Night Eclipse IP/BacNet(lighting controls), Tritium/Niagara N4 with NICS statement, IP BacNet protocol open license, software, service took, Distech Eclipse IP/BacNet, Bosch addressable security keypads and controllers, and Honeywell Firelite (fire panel addressable systems). After discussion, the PBC agreed that these systems must be proprietary in order to be cohesive with the TOL systems. 7. PBC APPROVAL VE/TOTAL PROJECT BUDGET Following tonight's meeting, and after the SC meeting held on 12/19, that at the joint PBC/SC meeting we will ask for the following approvals: ➢ VE Items to Incorporate ➢ Total Project Budget ➢ Proprietary Letter Approval Hastings portion of the meeting ended at 7:07pm DORE AND WHITTIER MANAGEMENT PARTNERS, LLC.
