Cable-stayed bridges have gained popularity as a design solutionfor long-span applications in north america. With their advent and implementation, several significant contractual, technical, and personnel-related controversies have evolved that threaten to slow the implementation of this design concept. These problems are reflected in the conflicts and claims currently plaguing the industry. A variety of constructability concepts collected from a unique blend of owners, designers, suppliers, and contractors associated with recent cable-stayed bridge projects are described. The constructability concepts relate to tower design and construction, cantilever deck design and construction, composite deck design and construction, stay-cable configuration and construction, posttensioning component operations, reinforcing steel details, prefabrication operations, stressing operations, grouting operations, closure, and general work sequencing. The concepts provide a starting point for review of designs for efficient and economical construction.
