After years of work and getting its necessary approvals in place over the summer, the Police Department Building Committee is nearing a construction date. In a recent update to the Town Council, members of the committee talked about finances, among other business: On Sept. 19, the Board of Selectmen approved nearly $360,000 to start construction of the project, which is expected to cost about $29 million. The town has a contract with SLAM Collaborative, an architecture group with an office in Glastonbury, to renovate the police station. Turner Construction Company joined the project in March. Joe Zagarenski, the town’s senior engineer, said the entire project should total about $29 million, a budget total approved by the Board of Selectmen on Sept. 5.
