Emeryville Breakwater Replacement
Work involved the bathymetric survey, site reconnaissance, coastal engineering analysis, engineering design, opinion of construction cost, and the preparation of construction drawings and specifications for the replacement of the deteriorated timber breakwater with a concrete structure. The design consisted of precast concrete panels and batter piles and a cast-in-place concrete deck and cap. Half of the structure provides fishing and public access. Special details were included in the design to enhance water circulation and encourage native oyster colonization. A design challenge consisted of specifying sheet pile and batter pile lengths for the highly variable foundation soil profile.
The work also included design for replacement of a windsurfing launch ramp. NCI performed construction engineering and resident inspection during the construction.
