Abstract:

Remedial work to an existing bulkhead at a deep-water berth for Port Everglades, Florida, has been done with substantial savings through the application of innovative design concepts. The use of a performance specification in the acquisition of steel wall components has allowed the Port to accept a composite H-Z wall section. This section provided a 331 ton (300 metric ton) savings over the lightest deep Z-sheet pile section capable of meeting the design requirements. The use of diagonal post-tensioned auger cost piles in lieu of the traditional horizontal rod/dead-man wall provided additional savings. Both concepts have provided a combined savings of 24% in the materials/construction portion of the project.
