Project Summary

ATM coastal engineers developed a Beach Nourishment Plan for the Town of Palm Beach, Florida. The one-mile project was developed based on an analysis of coastal survey data, and geotechnical investigations. ATM engineers developed a plan for a supervised field acquisition of vibracore sediment samples to confirm material suitability, and refine the area of cut within a previously identified borrow area. A 900,000 cubic yard beach nourishment project was designed to provide total protection for 15-year storm design. Design plans and specifications were prepared. A field of 11 groins was designed using 26-ton concrete modules, foundation mattresses, and armor rock to reinforce the beachfill. ATM conducted final phases of the project which included final design specification, government permits and approvals, establishment of Erosion Control Line, obtaining Federal and State grants and permits, all bidding contract documents, contractor selection, and contract award.

A fast-track schedule provided all construction permits in three months. A comprehensive biological and performance-monitoring program was developed and implemented. A highly unique project maintenance program was formulated with a 10-year permit to allow for timely implementation. Construction of the project was completed in March 1996 with ATM responsible for all construction management services.
