UNIVERSITY OF WASHINGTON
OCEANOGRAPHY PIER RENOVATION

2005 ASCE Seattle Section Outstanding Award for Excellence in Small Projects

CG Engineering participated in this project as engineering prime consultant for the University of Washington. A condition assessment of the existing pier was completed in a written report format. Recommendations for pier renovation were completed along with a construction cost estimate. Construction documents addressed permitting issues, fire safety and light provisions for the Department of Fish and Wildlife. CG worked with the University, the Department of Fish & Wildlife, and other permitting agencies to provide 60% ambient light transmission for migrating salmonoids by using steel grating on the deck. This project also involved the installation of 18 new steel piles and replacement of timber members above pile caps.

MACKAYE HARBOR PIER

CG Engineering was chosen by the Tulalip Tribes of Washington to provide permitting services and structural engineering evaluation and design for the renovation of an existing pier approximately 12 feet wide & 700 feet long and several accompanying floats.

The pier is wood framed with timber piles. Much of the renovation had been completed previously without a permit and the Army Corp of Engineers required an "after the fact" permit. This required a JARPA permit application & coordination with other state & federal agencies.

MEADOWDALE MARINA PIER RENOVATION

CG Engineering is providing civil and structural engineering for this project involving the renovation of the Meadowdale Marina Pier. Structural design involves the replacement of 277 timber piles with 230 steel piles in the existing pier. Approximately 27,000 lineal feet of creosote treated pile caps and 45,000 square feet of timber decking will be removed. The adjacent concrete pier and metal building added in the 1970s will remain. A pedestrian walkway will be designed at one side of the access ramp. Steel deck grating will be designed, allowing ambient light transmission for migrating salmonoids as required by the State Fish & Wildlife Department. Civil design will include the layout for water, sanitary sewer, and storm sewer with water quality treatment located in the parking areas. The design of the sanitary sewer holding tank and pump station will be required to service the pier development.
