Canton School Building Committee approves geothermal contract amendment, $1.545 million in invoices; reviews budget, schedule, sustainability and site lighting

The Canton Public Schools School Building Committee on March 19 approved a contract amendment to cover a completed geothermal test well and authorized $1,545,440.60 in project invoices while receiving updates on the project budget, schedule, sustainability incentives and design decisions for the new GMS building.

The committee voted to approve Consigli Contract Amendment No. 2, which moves $141,415 into the construction budget line for a geothermal test well whose work was completed Jan. 6. Jen Carlson, a Left Field representative who presented the item, said, "That well was all that work was completed by January 6," and explained the amendment shifts completed preconstruction work into the construction budget category.

The committee also approved four invoices totaling $1,545,440.60, including Left Field invoice No. 22 for $205,112, AI3 invoice 14B for $1,180,578.60, Consigli invoice No. 3 for $158,899 (which includes the geothermal amendment amount), and a $851 invoice for legal review by Brooks and Dorensis. The motion to approve the invoices carried by roll call vote.

Why it matters: the amendments and invoices move already-completed work into the correct budget lines and keep the project on its document-and-cost schedule as the design advances toward MSBA submission milestones. Committee members reiterated a continued focus on preserving contingency funds while advancing design development.

Budget and schedule highlights Committee members were shown a monthly budget snapshot that reports $28,676,302 as committed to date through amendments and contracts and roughly 6% of the construction budget held in contingencies. The transcript did not provide a precise "spent-to-date" figure in a consistent numeric form; that value is not specified in committee materials distributed at the meeting. The presentation included a contingency balance listed roughly as $11,720,706.

On schedule, the consultant team said documentation work is continuing through mid-2026 with a two-year construction target and planned occupancy in fall 2028. Design-development milestones cited in the presentation included intermediate milestone submissions to the Massachusetts School Building Authority (MSBA) and a 100% documents target in early June of next year to support estimating and early work packages.

Sustainability and incentives Design consultants told the committee the project is tracking to pursue Mass Save incentives and is being configured to maximize potential reimbursements by meeting the program’s higher-tier requirements. Justin (design consultant) said the project is "on target to pursue tier 1" and that the committee will be asked to vote at the next meeting to formally enroll in the program. Consultants and members emphasized there is no guarantee incentive levels will remain unchanged; presenters repeatedly described future incentive amounts as subject to change at the state or utility level.

Design, materials and program feedback Design leads John (design consultant) and Justin reviewed material selections and program adjustments informed by staff meetings with Principal Mulhern and GMS educators. Key material and design choices presented: - Sheet linoleum for corridors and high-use areas to reduce off-gassing and ongoing maintenance (no cyclical stripping/waxing); carpet tile in office areas for spot replacement; porcelain tile in restrooms and quarry tile in kitchen areas. - Acoustic ceiling tiles (ACT) in most classrooms, painted gypsum board and select exposed or wood-paneled decorative zones in larger public spaces. - Exterior cladding proposed as roughly 80% brick with fiber-cement panel and PVC trim; a PVC roof membrane; concrete sidewalks and decorative pavers at primary entries.

Staff programming feedback included changes to the gym/dining visibility (adding shading to limit distraction), relocating gear/computer storage closer to the gym, mirroring chorus/performing arts riser orientation, and refining egress and parent pickup paths so visitors can reach the nurse’s office without transiting the student dining space. Consultants said they will present updated plans to staff before school ends in May.

Solar readiness and PV options Consultants confirmed the building is being designed to be "solar-ready": roof structure and conduit pathways will be included so photovoltaic arrays can be added later as an alternate. Justin said PV is currently an add-alternate in cost estimates and will be designed into the project so it can be installed later if budget and buyout allow. Committee members asked for cost estimates for PV and were told those will be included as alternates in the estimating set.

Geotechnical and geothermal work, abutters notice The team reported additional geotechnical work planned over April vacation: about 24 borings and five test pits to refine subsurface and infiltration design now that the building footprint is locked. The permanent geothermal well field is planned under the hockey rink; consultants said the previously completed test well will be part of the final field. The committee scheduled an abutters meeting after the April 16 SBC session to notify nearby residents about planned site borings and enabling work.

Site lighting and neighborhood concerns Committee members discussed whether to include athletic lights for the relocated basketball courts and hockey rink. The synthetic turf field and its athletic lighting were already included in the project scope; lighting for the hard-surface basketball court and hockey rink was not budgeted. Members expressed concern about late-night organized play and neighbor impacts and leaned toward limiting those surfaces to general site/safety lighting rather than full athletic lighting. Consultants will include ad-alternate line items for full athletic lights on the estimating set so the committee can see costs before deciding.

Votes at a glance - Approval of SBC meeting minutes (Feb. 26, 2025): motion by Bob McCarthy, second by Bob Benedetti; roll-call votes recorded in the meeting transcript show a majority of aye votes with one abstention (Mary Graziano); motion passed. - Consigli Contract Amendment No. 2 (geothermal test well, $141,415): motion by Mr. Scollins, second by Mr. McCarthy; roll-call vote result recorded as 8–0 in favor. - Project invoices (Left Field $205,112; AI3 $1,180,578.60; Consigli $158,899; Brooks and Dorensis $851; total $1,545,440.60): motion by Bob Benedetti, second by Mary Graziano; roll-call vote result recorded as 8–0 in favor.

What’s next The committee will receive the virtual walkthrough and updated renderings at the April meeting; a community/abutters meeting will follow the April 16 SBC meeting to explain April-vacation site work. The committee will be asked at a future meeting to vote to enroll in Mass Save Tier 1 incentives and to approve any alternate line items the committee chooses to add after the estimating set.
