Two case studies are presented that provide an overview of aspects of design aiming at improved constructability. The first case study discusses the design of two segmental cantilever bridges constructed in very difficult site conditions. The second deals with the design of two long river crossings for a motorway, employing the segmental span-by-span erection technique using precast segments. The first case study focuses on features of design, detailing and measures for construction-stage stability that were studied with the objective of making the structure erection-efficient and cost-effective. The second case study views similar objectives by concentrating on conceptual planning, study of alternative designs and review of alternative erection techniques. Both case studies involve turnkey projects, the first one financed by an international financial institution and the second financed by a consortium of private financiers.
