Cianbro Says 'Specs' Followed on Chesapeake Bridge Job
Cianbro Corp., the contractor on a problematic Chesapeake Bay Bridge concrete repaving project, has provided detailed comments to back up its contention that it adhered to specifications and procedures approved by the Maryland Transportation Authority, the bridge's owner. For example, the Pittsfield, Maine-based company said, it repeatedly told the authority that the specified matrix restorer was breaking the overlay bond, not restoring it.
Delamination on parts of the repaved deck caused the state to have Cianbro redo a large portion of the overlay work and prompted state Transportation Secretary Robert L. Flanagan to bring in an outside review panel to determine what caused the problem. Flanagan also is restudying a planned second phase of the bridge project, which will delay its completion date for months.
