Concord School District committee reviews updated middle school design; elevators, stormwater and HVAC costs flagged

Designers and Concord School District officials gave the Building Committee a detailed update on the new middle school design, showing a refined site plan with separate parent and bus drop-offs, covered walkways, alternate athletics layouts and internal layout options for a multipurpose/auditorium space. The committee discussed elevator placement and capacity, stormwater detention needs for the downtown site and an updated life‑cycle cost analysis comparing ground‑source heat pumps and conventional natural‑gas boilers.

The presentation, led by Holly (project presenter), laid out a parent drop‑off on Conant/South Street, buses entering at a separate rear entrance, a covered walkway linking parent and bus entrances and multiple field layouts (three soccer fields in the preferred option versus a baseball/softball configuration). Holly said, "So here's the site plan that's been further developed," and walked the committee through circulation, covered walkways and locations for service and maintenance access.

Why it matters: the site and building choices will shape construction cost, student safety and long‑term operating expenses. The committee will use alternates and a life‑cycle cost analysis to decide which tradeoffs to accept before issuing construction estimates and finalizing a budget.

Most important elements presented

• Site circulation and safety: Designers showed separate routes for parents and buses, a covered walkway, and staff parking tucked behind the building. Committee members flagged an existing four‑way merge where Abbot Downing’s parking lot exits and described current parent behavior—dropping and walking across traffic—that the new layout aims to reduce. Staff said there will be bus‑only signage at the rear entrance and staff parking behind the building to discourage drivers from entering the bus zone.

• Athletics and outdoor space: The preferred site plan depicts three soccer fields (one potentially turf) and a separate play area, plus a layout alternate with baseball/softball diamonds and one multiuse field. Designers noted a planned buffer of shrubs and retention of an existing row of trees where possible to screen neighbors.

• Building program and spaces: The academic wing preserves three team pods stacked over three floors, a central cafeteria that opens to a north courtyard, music and theater spaces north of the entry, a 5,000‑square‑foot multipurpose room on the northwest corner, fitness/OT/PT and maker/robotics spaces. The media center sits above the public entry with a visible tech/help desk. Designers said they had consolidated most special‑use classrooms to the first two floors to improve circulation and ramp access.

• Auditorium and multipurpose options: The proposed theater is a flat‑floor, flexible space intended to allow larger ensembles; designers proposed curtains and a pipe grid for hanging lights and sets rather than a permanently raised stage. The design shows retractable bleachers and loose seating to reach a total capacity the presenters described as about 450 people (280 in retractable bleachers, approximately 20 on the floor and about 150 in a balcony).

Accessibility and vertical circulation

Committee members pressed on elevator capacity and placement. Presenters said the current design includes two elevators: one larger elevator sized to accommodate a stretcher and a second, somewhat smaller elevator adjacent to the ramp and stair. Several committee members expressed concern that a single elevator serving parts of the program could create delay for students temporarily unable to use stairs (injuries, mobility needs) and asked staff to study moving or re‑siting an elevator to shorten travel distances. Designers confirmed elevator footprints can be adjusted and said they would evaluate a centrally located elevator option and place a second elevator on a budget contingency/alternates list.

Stormwater, site constraints and utilities

Because the selected downtown site is more constrained than the previously considered site, civil engineering work is under way to design required stormwater detention. The presenters said limited surface area will likely require mostly underground detention systems (rain gardens on site where possible), and they warned that underground detention can add cost and require coordination with parking and potential future solar or geothermal layouts. The civil engineer is designing stormwater retention and will include those requirements in the upcoming cost estimates.

Energy systems and life‑cycle cost analysis

The project team said it is revising the life‑cycle cost analysis to account for natural‑gas condensing boilers with an air‑cooled chiller as one option and ground‑source (geothermal) heat pumps as another. The team stated it has contacted local utilities (Liberty Gas and the electrical provider Unitil) to gather connection and service information. Presenters noted that federal incentives previously available under the Inflation Reduction Act had been a factor in earlier analyses; recent federal legislation developments were described as changing the tax‑credit picture for solar PV though credits for ground‑source heat pumps remained available at the time of discussion. The life‑cycle cost analysis will include operational cost, greenhouse‑gas impact and tax‑credit scenarios and will be returned to the district sustainability committee for review.

Budget and schedule direction

Design completion is targeted for July 17. The committee was told a private construction estimator will need about a month to price the design and the team will present a set of priced alternates (cafetorium vs. separate multipurpose room, one vs. two elevators, turf vs. grass fields) to inform a new budget by September. The committee directed staff to: (1) finish the life‑cycle cost analysis including greenhouse‑gas comparisons; (2) complete civil/stormwater designs for the site; (3) collect utility connection fees and constraints; and (4) compile a menu of alternates for pricing.

Decisions and next steps

No final construction selections were made at the meeting. The committee set design completion and estimating milestones and asked the project team to return with costed alternates and updated analyses. The meeting adjourned on a motion moved by Miss Vaughn and seconded by Miss Fox; the committee voice vote was recorded as "Aye."

Ending note: The project team will return with updated cost estimates and alternates; the committee expects a revised budget in September and anticipates discussing elevator placement, stormwater solutions and HVAC selection before final approvals.
