The second phase of an extensive project to replace the Annapolis City Dock bulkhead began in October 2015 and was completed in Spring 2016. EBA designed both phases of the project and also provided construction management and construction phase services, including inspection and testing.
In all, the project involved installing 700 linear feet of cantilevered steel sheet pile with concrete cap bulkhead, as well as new slips and timber mooring piles. The project also included upgraded utilities, water connections, and fire protections systems for the dock’s 17 boat slips.
Phase 2 focused on protecting the inner City Dock. One key to project success was using a cantilever design for the new bulkhead instead of a tie-back system connected to a deadman. This minimized the total area disturbed for construction, reducing environmental impacts, impacts to businesses (parking and traffic), costs, and potential historic/archeological impacts through less excavation.
The project had to be completed within an aggressive 6-month timeframe, between the end of the Fall Boat Show and before the start of the Spring Boat Show. The entire project team worked together to meet this demanding schedule. The bulkhead replacement project was not only completed on time, but also came in under budget.
The project received the Outstanding Project Award in the American Council of Engineering Companies Maryland (ACEC/MD) 2017 Engineering Excellence Awards competition and the 2017 Outstanding Civil Engineering Achievement (Small Project) Award from the American Society of Civil Engineers (ASCE) Maryland Section.
