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.
Joint ventures worked through
- Metro Bild consortium
- Metro Sifer consortium
Work done in a joint venture is credited to each member firm, so a venture has no page of its own and never appears beside its members: that would count one section twice.
