Concord building committee reviews $171 million middle-school estimate; debates solar, soils and cuts

Concord School District building committee members on Sept. 10 reviewed a reconciled cost estimate of $171,000,000 for a proposed new middle school at the Runlet site and discussed options — including geothermal, rooftop solar and a long list of value‑engineering items — to reduce taxpayer impact and schedule risk.

Barb, an architect with HMFH, told the committee that the reconciled total includes the building, site work and soft costs and warned the group that the site’s soils were worse than expected. “It's a $171,000,000,” Barb said, listing the roughly $123,000,000 building cost and about $20,000,000 in site work as the primary components of that total.

The estimate and follow‑up discussion matter to taxpayers because the district’s finance staff presented scenarios showing how borrowing and rebates could change property tax bills. Jack, the district’s finance presenter, said one financing scenario would result in an initial increase of about $228 a year for an owner of a $350,000 home, and noted that net reductions are possible in subsequent years if the district uses trust funds and anticipated rebates.

Why it matters: committee members said the project’s cost, timeline and the district’s ability to capture federal tax credits could determine whether the district proceeds now or delays, which would increase escalation and risk. Architects and estimators also said site conditions require ground improvements that add time and expense and make renovating the existing school on its current footprint infeasible without moving students off site.
