At least 80 percent of the ceiling at Westwood’s new 32,000-square-foot library have been removed as officials seek to learn why the wooden slats began to fall to the floor in January.
Library officials reopened the High Street building this week after extended closures the last two months, and after tradesmen were called in to remove the ceiling by hand.
Members of the library’s Board of Trustees said in a news release Monday that a team of investigators and specialists have been gathered by the town’s Permanent Building Committee to determine liability and research what kind of new ceiling should be installed.
“This will require a careful examination of alternatives, costs, and public safety,’’ they said in a public apology.
