Visitors Center— Don Mills (Mills Whitaker Architects) Don's presentation showed updated floor plans and discussed suggested changes. Budget and Schedule were also reviewed. • Don recommended a slate roof with copper for the slope areas. Slate is less expensive from a life cycle cost and keeps with the HDC want for authentic materials. Wood shingles are in the budget. Although slate is an extra $40,000, the Architect had other items discussed below that can offset the extra $40k. • The 2nd floor shows a slight revision for the staff coat closet. • The 1 st floor review discussed the BOS's recommendation for the staff bathroom to be an accessible one. It was stated that there is an accessible bathroom in the building on the basement level accessible by elevator. It was stated a staff bathroom is needed. How this would affect the much needed stockroom area was discussed and suggested further conversation with the BOS is needed. • White oak flooring will be used for the 1 I floor creating a warmer environment compared to the originally suggested concrete floor. The white oak also provides a cost savings. Use of the 1 It floor and basement for exhibiting various displays and artifacts was discussed. A request to install a projector and screen in the Revolution History Room will have further discussion on how it could be set up and that it could be purchased after the construction bid. • Site materials discussed the use of stone dust leading up to brick walkways. Bluestone to be used under the veranda. A walkway to the Buckman Tavern was proposed. The Projected Budget: $4,575,000 Bidding Period: Feb. — Mar. 2019 Construction: May 2019 [after Patriots Day] — March 2020 [before Patriots Day] 201 BEDFORD STREET 9 LEXINGTON, MASSACHUSETTS 02420 2. Westview Cemetery—Justin Humphrey(TBA Architects), Dave Pinsonneault (DPW Justin's presentation reviewed the Cemetery Building Program, which does not include a crematorium at this time. As the original proposed plan showed, it will be a single story building consisting of administrative space, a 4 bay garage & maintenance area, and outdoor material storage bins. • The front entrance has been reworked for the potential of adding a crematorium or pavilion in the future. • The main entrance to the building would now be off Westview Street. The building's exterior is proposed with metal clad and brick materials. PBC asked about the utilities. Justin stated it will be an electric building, (gas not being used), with water coming in off of Westview. The building will have its own septic system. There is an estimated $300,000 savings taking gas and sewer connection out of the plan. PBC suggested that it might be prudent to size the septic system for a possible expansion. It was stated an AD HOC committee is being formed to review the crematorium. Town Meeting member Narain Bahtia spoke, giving information on the crematorium and stated he is working on a Warrant Article to appear at the next town meeting. He stated that only one retort would be required. DPW stated they would like to get funding through construction for this project at the Fall Town Meeting and get the process going. Dave stated they would like to break ground by spring and be done before winter. 3. Hastings School — Michael Burton (Dore & Whittier), Frank Morse (Walsh) Minutes submitted by Christina Shefferman Hastings portion of meeting started at 8:35 pm. M. Burton starts meeting by following power point presentation regarding 90% Construction Documents of the Maria Hastings Elementary School Project. The agenda followed stated: • 90% CD Cost Estimate Reconciliation Recap • Construction Budget Comparison/Progression • Total Project Budget • Value Engineering • Approval to submit 90% CD Submission Reconciliation Recap: • Reconciliation held w/ DiNisco, Walsh, & DWMP on 8/8/18 @ WBI Office • Estimates from Walsh Brothers and AM Fogerty were reconciled to a >1% Variance • AMF Reconciled estimate to be used for 90% CD Submission to MSBA(August 13th, 2018) • Financial approvals to be sent o MSBA upon PBC approvals M. Burton goes on to review Budget Development (side-by-side) comparison slide. PBC Meeting 08.16.18 2 The slide shows the SD, DD, 60% CD, and 90% cost estimates reconciled with the comparisons. Overall the 90% CD estimate reconciliation shows a revised assumed total and a variance from budget. The assumed total is $52,971,525 with a variance of$1,893. M. Burton reviews the Estimate Comments slide. This slide shows: • Estimate adjusts design contingency to $100,000 • Estimate adjusts Escalation contingency to $250,000 • Reconciled estimates showed savings of approx. $635k • Current budget addressed Sitework issues identified during Early Release Package Boulders $3k Mulch $8k Playground revisions $20k Unsuitable soil removal and import (Actual) $400k Unsuitable soil removal and import (Projected) $200k Total: $631 k M. Burton reviews Total Project Budget slide. The slide shows: Total Construction Cost: $52,971,525 Soft Costs: $10,306,000 Owner's Contingency: $2,000,000 Total Project Budget: $65,277,524 After reviewing 90% reconciliation information M. Burton reviews remaining VE items slide. After reconciliation the team reviewed and added new VE items to the list that can be taken. M. Burton states that N.1, remove spray foam from exterior cavity wall with a value of$110,148 should be taken since the building already has a moisture vapor barrier. The spray foam is an additional step that is not needed. DiNisco has reviewed with the commissioning agent, as part of the envelope it is not required based on their energy model or the R value. DiNisco to further review with LEED engineer and LEED consultant to determine if necessary. Further N.2 from the VE was also recommended to be taken, remove 4" chain link fence from north and south elevation with a value of $35,000. The fence is an added cost that is not needed and or required on the north and south side of the property. M. Burton states that the prequalification team evaluated all SOQ's received for the public trade qualification process. All but one contractor was prequalified. Drawings will be available to the contractors on 9/10/18. A motion was made by J. Himmel and seconded by D. Perry to approve the 90% CD reconciliation of$52,971,525 and to submit the 90% CD package to the MSBA. Discussion: J. Himmel asks that the approval be based on what was approved back at SD with a value of$52,973,418. Vote: All in favor. Motion passes. PBC Meeting 08.16.18 3 A motion was made by J. Himmel and seconded by D. Perry to approve the recommendation from the prequalification committee of the prequalified trade contractors based on the evaluation conducted. Discussion: None. Vote:All in favor. Motion passes. Hastings portion of the meeting ends at 8:53 pm. 4. Lexington Children's Place— Donna DiNisco, (DiNisco Designs), Vivian Low(DiNisco Designs) Donna updated the committee the late start for demolition was due to National Grid's delay on getting the natural gas on site capped. Demolition is now underway; however, S&R is slightly behind schedule with an original date of completion by Sept. 1St. S&R is working hard to wrap up demolition before Sept. 11 to • Filed sub bids have been received and need to be awarded by Sept. 10th. The GC bid date has been extended. • A review of the August 1St, 2018 Green Engineering Report stated: "Figure 1 below presents the energy use index (EUI)of the Code Baseline and the Proposed Design. In summary the design exceeds ASHRAE 90.1 2013 requirements with 50% site energysavings. This translates to a LEEDv4 energy cost savings of 20.6%. It is important to note the distinction that Code references energy use performance while LEED references energy cost performance. The Green House Gas(GHG) emissions for the proposed design are estimated at 34.5 MTCO2e, an approximately 40.2% reduction from the Code Baseline." • PBC discussed the topic of gas onsite brought up at the Aug. 28th BOS, SC and PBC meeting. There is apparently a big misconception in town about the intent of this emergency gas fire element and the presents of gas on the site. The existing building had gas service. The gas fired element being proposed is strictly for emergency use during the coldest months of the year should there be a utility company power outage. The proposed emergency generator is being sized to provide power to run the life safety requirements of the building, primary functions related to the buildings required `resilience' rating, and the two VRFs service the classroom wings. The option is to upsize the generator and burn more fuel generator electric or supply an inexpensive gas fired element to heat the administrative wing. Further discussion is needed regarding using gas for backup use only. 5. School Master Plan Discussion— Kate Colburn (School Committee) Kate addressed that the last School Master Plan was in 2014, with projects being completed and new ones beginning. Enrollments continue to rise, and the SC suggests taking a new look at the current Master Plan. Kate would like to form a group of 15 people from various committees, and is looking to start efforts in Sept. and complete the review by the end of the school year. Mike Cronin suggested that PBC members interested in participating on the School Master Plan should email him. PBC Meeting 08.16.18 4 6.
