The long-awaited Knock Knock Children’s Museum has hit another snag after years of slow-downsand problems.

The museum was supposed to have a contractor in place by the end of this month, but BREC Superintendent Carolyn McKnight said the bidder who they wanted to hire pulled out of the running this week.

McKnight said the remaining bids are above the $6 million that has been raised for the building’s construction. She said she will meet with Knock Knock Children’s Museum officials next week too see if there’s any wiggle room in the budget and to chart their next course of action.

“We’ll have a plan mid to late next week about Knock Knock,” she said.

The Children’s Museum will be located on City-Brooks Community Park property on Dalrymple Drive near the LSU campus. Projections for its groundbreaking and completion have continued to be pushed back, as it was at one point scheduled to break ground in the summer of 2014.

The building’s renderings show it perched on a sloped hill, with three peaks and large patches of windows.

Overall, those leading the effort to build the museum have raised more than $9.4 million to build it and to stock its interior learning zone spaces. Most recently, the museum secured donations totaling $850,000 for a construction-themed building and learning zone.
