Ductile Iron Piping Systems Used in the Design and Construction of the Panama Canal Third Set of Locks Project

The Panama Canal expansion is a $5.25-billion project sponsored by the Panama Canal Authority, which includes $3.2 billion for the design and construction of the third set of locks. Buried beneath the new sets of locks’ footprint are 80,000 feet of ductile iron pipe, providing potable water, dewatering and fire protection service to the new locks’ facilities and the surrounding communities. This paper will discuss the pipe design, selection, design/build challenges encountered during the process and how it affected the pipe manufacturing and scheduling. It will demonstrate how the use of three dimensional (3D) modeling software was used to coordinate the ductile iron pipe with other buried utilities. It will present a unique installation of 30-inch and 24-inch potable water flanged ductile iron pipe crossing underneath the lock structure that required a 450 psi hydrostatic test on the 30-inch pipeline after installation. Due to the unique high performance requirement, which reached beyond normal testing criteria for water piping, special design and testing for the joint system was developed for this project. The paper will also describe how teamwork and cooperation among the designer, the contractor and the equipment manufacturer/supplier were essential for the successful construction and operation of the ductile iron piping component of the overall megaproject.
