Improving Productivity on a Troubled Bridge Project.

This paper presents a case study of a bridge constructed under adverse conditions in rural Florida. The major challenges facing the contractor were clearly identified through analysis. The bridge was constructed by an established, experienced bridge contractor that faced many daunting challenges in the construction of the bridge foundation, ranging from overdesign to the project manager managing his first construction project. However, the biggest challenge was unforeseen site conditions; namely, some of the most difficult clay imaginable through which to drive piles. These challenges forced the contractor into several tactical maneuvers. In sharing both the methods adapted by the contractor and the results of the adaptations, this paper quantifies for researchers and practitioners how a good contractor made sound, fundamental decisions to overcome severe challenges, improve productivity rates midproject, and eventually make the project a success. A seeming disaster early on, the project was eventually completed in less than the contract duration and at a sizable profit for the contractor. [ABSTRACT FROM AUTHOR]
