TITLE
Recommendation to authorize City Manager to execute the Seventh Amendment to Contract No. 31687 with Bellingham Marine Industries, Inc., for an additional $162,300, plus a ten percent contingency of $16,230, for a total increase not to exceed $178,530 to perform emergency maintenance dredging and repair of the Peter Archer Rowing Center Dock, located in the Alamitos Bay, for a revised contract amount not to exceed $39,510,295. (District 3)
DISCUSSION
On May 20, 2010, the City Council awarded a contract to Bellingham Marine Industries, Inc. (BMI), for the design, engineering, and construction of the Alamitos Bay Marina (ABM) rebuild (project). Due to the magnitude of the ABM project, the Department of Parks, Recreation and Marine (PRM) and BMI agreed to segregate each basin rebuild into phases.

The Rowing Center is maintained and operated by the Long Beach Rowing Association, with subleases to California State University, Long Beach and Long Beach Junior Crew, for the shared use of the indoor and outdoor premises. The floating dock has suffered from an increase in sediment accretion beneath it limiting the dock’s functionality during low tides and weakening its overall structural integrity. During low and extremely low tidal events, the dock rests on a mound, becomes deformed and saturated and creates a tripping hazard that must be repaired. The combination of these conditions results in the observed “crown,” which continues to impact its floatation (Exhibit B). The floating dock was designed to have a low freeboard to accommodate the launching and retrieval of rowing shells. Dredging is now required to alleviate this abnormal condit...
