Contract Amount: $66,732,456

Project Duration: July 2000 - August 2002

Project Description:

This project, performed as joint venture, involved the construction of a 3,600 linear foot concrete wharf and partial yard improvements at Berths 57/58. The concrete wharf is supported by 48” diameter precast concrete cylinder piles and 24” octagonal precast concrete piles. The wharf included 100’ gauge crane rails with an electrical power trench and a high energy absorbing fender system. In addition to the wharf construction work, Manson performed 2,400,000 cubic yards of dredging and rock removal and 400,000 tons of rock slope protection. The dredge spoils were used to create an upland fill area. Wick drains were installed in the fill followed by placement of a surcharge. 

The soft, existing soils beneath the inshore side of the wharf were stabilized with cement deep soil mixing (CDSM) and a landside row of hollow prestressed, precast concrete cylinder piles, 48” in diameter, was installed. These larger 48” piles provide the required lateral strength for the wharf to resist the large seismic loads in the soft bay mud, eliminating the need for a rock dike.

Manson Construction received an “Outstanding” performance evaluation from the Port of Oakland on this project.
