Funding for the stalled Concord-Carlisle high school building project has been restored, more than six months after the state yanked $28.8 million worth of grant payments over concerns that the project had ballooned over budget and scope. The original agreement between the district and the Massachusetts School Building Authority granted the district $28,781,100 in state reimbursement; in the letter from the state dated Jan. 10, the grant is reduced to $28,587,347. At the end of June last year, the state halted grant payments to the district, saying that the $92.6 million project had veered off schedule, and that its design was over scope and budget. Last March, according to school officials, the project was poised to run between $15 million and $17 million over its $75.1 million building construction budget; those costs have since been reined in. The project was expected to break ground this past fall, but it has been on hold while district officials reworked building design plans. In the district’s newsletter, officials say that in spite of delays, the project is expected to be completed by December 2015. The next Building Committee meeting is scheduled for Wednesday at 7 p.m. in the library at the Concord-Carlisle High School.
