PIPE JOINT FAILURE CAUSED BY AN INADEQUATELY SPECIFIED CONSTRUCTED ENVIRONMENT

A number of 96-in. (244-cm) diameter AWWA C-302 concrete pressure pipe joints failed during installation. The failures were caused by an AWWA specification used in the wrong environment, lack of adequate pipe inspection, failure to understand the implications of the pipe specification joint tolerances, and failure to take into account pipe specification dimensional tolerances in the specified constructed pipeline environment. The pipe specified was AWWA C-302 Concrete Pressure Pipe, with "Carnegie" steel joint rings. Some of the contributing causes were improperly specified pipe bedding, a pipe standard specification which was inappropriate for the project conditions, failure to adequately inspect the pipe, and failure to store the pipe in the specified vertical position. The author identifies the causative factors and recommends steps which can be taken to avoid similar expensive pipe and bedding modifications, repairs, jobsite delays, and remedial measures which were required on this project.
