Sustainable Group, Inc.

Scope Of Work

In advance of the delivery of several new small boats to USCG Base Alameda, CA, this project required the repair and reconfiguration of the jet dock facility at the base. Sustainable Group teamed with Jet Dock Systems Inc. of Cleveland, Ohio to furnish the required material and the trained technicians to complete the required work. The innovative Jet Dock System uses a series of interchangeable modules that are filled with water to allow the small boats to drive onto the dock and then filled with air to lift the entire boat and dock out of the water. The simple procedure is then reversed to lower the boat back in to the water. The system is virtually maintenance free and has been deployed at countless marinas and military bases around the world. This project specifically required the modification of six existing 25 foot docks to 29 foot docks to accommodate the new Coast Guard Response Boat Small II (RBS II) boats. In addition, one entirely new 35 foot dock was constructed for the new Long Range Interceptor (LRI) small boat. Upon removal of the first existing jet dock assembly from the water, extreme corrosion of the aluminum support structure was observed. This condition was immediately brought to the Coast Guard’s attention and a modification was issued to replace the structural members. Additional zinc anodes were also affixed to the docks in order to prevent this corrosion from occurring in the future due to a very high degree of electrolysis within the estuary. Sustainable Group key personnel self-performed many of the construction activities for this project including towing the jet docks to the temporary work area, removing the jet docks from the water, and transporting the refurbished jet docks back to the operational location. On-site construction management, safety oversight, and Quality Control/Quality Assurance (QA/QC) services were also self-performed.
