Contract 15-03-06 consisted of the realignment and a 1045 linear feet extension of a Baltimore City storm drain from an existing outlet at the Fairfield Marine Terminal Wet Basin, to a new drainage structure adjacent to existing Pier 5. The project entailed driving H-pile and steel sheet pile for a temporary coffer dam and a permanent endwall and utility trench. The 13' by 8' box culvert installation consisted of a combination of pile supported cast-in-place sections and pre-cast sections. The excavation and installation of the box culvert was complicated by the fact that the invert is six feet below the water table. This required an extensive dewatering effort, especially to divert flow from the existing culvert during the tie-in process. A portion of the project also entailed traffic flow realignment through a well-traveled intersection to complete the tie-in with the existing culvert.
