GBS Infrastructure Construction
Bulgaria
- Sections
- 6
- Length
- 105 km
- Median slip
- −2 mo
- Median overrun
- –
Slip measured on 5 of 6 sections built.
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
- AM Struma 3.2.2 Consortium
- Struma Lot 3.3 Consortium
- Struma – 1 Consortium
- Struma-Lot 2 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.
