Constructability of cable-stayed bridges

The application of cable-stayed structures has increased during the last few years in North America. The implementation of these new structures has led to serious problems in the design and construction process. This paper provides an analysis of the most significant problems identified by owners, designers, and contractors. The owner-related problems include difficulties in four areas: the contract system, the bidding process, field representation, and project document reviews. Designer-related problems include incomplete design, lack of access to specification development, overly congested areas, and restrictive tolerances. Constructor-related problems include engineering requirements, inexperienced personnel, project planning, and shop-drawing specification. The paper proposes several modifications to mitigate the problems encountered. The paper includes suggested changes under the current contract environment, a modified current contract environment, and a completely new contracting approach for bridge construction. Each of the suggested changes are explained and analyzed for their potential benefits to the project outcome.
