No section this firm built records both a contracted duration and a delivery date, so there is no slip to report.
No section this firm built records both an estimate and a final cost.
Only construction counts toward these figures. A design contract is listed on the firm's page and never folded in, because a construction overrun belongs to whoever built the thing.
