After the latest round of updated cost estimates for the $94 million school project showed a $2.8 million shortfall, the the School Building Committee chose from a lengthy list of options provided by SMMA Architects to trim costs.
At several milestone points during the school project, the project team performs a new round of cost estimating; the latest estimates marked the end of the 60% Construction Documents phase. As it did after the first round of cost estimates last October came in about $9 million over budget, the SBC employed “value engineering” to decide where to save money This phase is when the specifications and details of building envelope and mechanical systems are decided, “so this difference in cost estimates is not unusual,” the SBC said earlier this month.

The biggest VE item by dollar amount is changing all proposed fiber cement rainscreen to brick, saving almost $507,000. The SBC has not yet decided on which of two brick options to select (see the Sept. 11 presentation starting with slide 18 labeled “Current design”).
In recent weeks, architect and longtime Lincoln resident Edmund Stevens has raised concerns about the school project on LincolnTalk several times, saying that the proposed removal of the bell tower “is nothing less than barbarous” and that the school building design resembled “a strip mall.” At the SBC’s second value engineering meeting on September 4, he objected to some of the proposed design elements and the SBC process in general. “I don’t think anybody really knows that this building looks like… it’s total chaos,” he said.
Stevens kept trying to speak after being asked to desist and said, “You’re not going anywhere!” But SBC member Peter Sugar silenced him with raised voice, saying “Neither are you, sir!”
Stevens afterwards told the Lincoln Squirrel that he had not participated in school project discussions up until now because he had been “out of circulation” with lymphoma, and because he initially thought the design would be “at least up to the level of the town hall renovation, which was excellent.” He said he did not vote at the Special Town Meeting that narrowly rejected a state-approved design in 2012 but could not recall why.
Going into the third and final value engineering (VE) meeting last week, “our VE decisions continued to be guided by our project principles, and no decision was without vigorous discussion and understanding,” said SBC member Kim Bodnar. “There were no easy or hardest items to cut. All VE items were met with rigorous scrutiny and an understanding of how they impacted the project.”
The project now moves into the 90% Construction Documents phase, when the final details are fleshed out in preparation for putting the project out to bid for areas that are subcontracted such as plumbing and HVAC, etc. This phase will be complete by the end of December and one more round of cost estimates will take place before the bid documents are finalized.
