Project Specifics

Located next to the cruise terminals in St. Thomas Harbor, the Yacht Haven Grande facility was designed to become a world-class yachting destination. As the primary marine consultant for the harbor restoration project, Geosyntec evaluated the market for the proposed facility, recommended a design layout based on market demand, and assessed the financial viability for the proposed restoration.

Geosyntec Scope of Services

We provided engineering design and construction oversight for the final marine facility, which offers more than 16,000 linear feet of total berthing capacity and incorporates two distinct components: one targeted to megayachts and the other to traditional marina tenants. The megayacht basin provides flexibility for varying characteristics, including 48 slips that include dedicated slips for vessels between 80 and 175 feet, docks that allow alongside-berthing of vessels up to 350 feet in length, enhanced site security, in-slip fueling, waste-oil recovery and pumpout service, high-capacity electrical supply (up to 600A), and separate docking facilities to provide owners and guests with the level of exclusivity they demand.

Complete design and construction documents were developed for the demolition, dredging, and revetment rehabilitation along the 1,500 linear feet of shoreline. Geosyntec also completed detailed design of the marina electrical system and provided design criteria, review, and coordination of marina pier and plumbing utility design-build project components. We also supported all phases of project construction.

Notable Accomplishments

This project was honored with the 2020 PIANC Marina Excellence Design Jack Nichol Award for outstanding marina design. It was also the first North American marina to ever be awarded Gold Anchor Platinum Level accreditation from The Yacht Harbour Association.

Note: At the time of this project, Geosyntec practitioners were contracted as ATM, which was acquired by Geosyntec.
