摘要:

In this paper representational data are given that can be used for the planning of single-span prestressed bridge construction. The project-network is represented, together with the critical path and time–cost relation, which has been calculated. Schedules for manpower and equipment required for project completion are also shown, as well as the owner's cash flow. The application of such data to construction of similar projects in different locations and/or in the future is discussed. The bridges under consideration were constructed using precast, prestressed concrete beams and the deck was castin situto act compositely with the beams. To establish these data, the daily work reports and progress payment certificates of five bridges, built in southern Ontario between 1976 and 1980, have been analyzed. Average values, based on the data of the five bridges, were utilized in this analysis.
