Frenchman's Harbor

This residential development is located at the corner of Donald Ross Road and Ellison Wilson Road in northern Palm Beach County. WGI’s Structural Solutions Division provided design services for construction of three box culverts, two bridges, 7,500 linear feet of seawall, 3,200 linear feet of retaining wall, and wood docks for each lot.

The site is environmentally sensitive and contains both wetland and upland areas. To protect the area, approximately 3,200 linear feet of retaining wall was installed, effectively dividing the upland development area from the wetland area. There are two man-made canals bisecting the upland development area, which gives each lot a waterfront location and easy access to the Intracoastal Waterway. These canals required installation of approximately 7,500 linear feet of seawall and allow each lot to have their own dock. An existing waterway flows through the center of the site and a unique underwater box culvert separates the wetland waterway from the man-made canal, allowing for uninterrupted flow of water, without mixing the two water bodies.

WGI also provided construction phase services, including shop drawing review, RFI responses, and attending preconstruction meetings and periodic milestone meetings. WGI was on site during construction to observe construction activities, including concrete placement, pile installation, sheet pile installation, dock installation, bridge deck installation, and post-tensioning. Being the engineer of record and CEI for this project allowed WGI to quickly and efficiently solve any construction-related issues that arose during construction.
