Construction Errors: Bridge Pier Case Studies

Three case studies of bridge‐pier‐related problems are presented. The first two concern problems during the construction of new bridge piers, while the third examines the reconstruction of an existing bridge. The first case is associated with an error in a construction drawing, the second involves inadequate pier survey, and the third is related to poor judgment in the inspection of the bridge‐pier base. The enabling causes of these problems were poor planning and supervision prior to and during construction stages. As design and construction of bridges becomes more and more complex, component details can be easily overlooked without adequate planning and supervision. Despite their significance for pier performance, such problems are generally unreported, and even if they are investigated, the results are seldom publicized. These problems, which cause project cost overruns and delays, can be avoided by emphasizing stricter quality‐control measures.
