The District Wharf in Washington DC is a $3billion waterfront redevelopment project that features a mile of new bulkhead, 3 marinas, 5 new piers, a mooring field, and 6 over-water buildings.  It is one of the most popular destinations in Washington DC and has been very successful.  This presentation will present lessons learned during the design, permitting, and construction of the project, as well as what works and what doesn’t work after 5 years of operations, based on interviews with the engineers, owners, operators, and contractor involved.
