City Council Meeting: June 23, 2009
Agenda Item: 1-F
To: Mayor and City Council
Subject: Pier Structural Upgrades and Gangway Project
Staff recommends that the City Council authorize the City Manager to negotiate and execute a professional services agreement with URS Corporation in the amount of $430,000 plus 10% contingency in the amount of $43,000 for a total amount not to exceed $473,000 to provide design services for the Pier Structural Upgrade and Gangway Project.
The Pier Infrastructure Assessment Study recommended safety improvements to the Santa Monica Pier including Municipal Pier structural upgrades and the construction of an emergency gangway. The Municipal Pier structural upgrade is intended to replace a structurally deficient section of the existing Municipal Pier with a new structure that is capable of handling the loads imposed by emergency vehicles. The emergency gangway will allow the evacuation of the Pier to the west in the event of a fire or other emergency. URS Corporation is recommended for final design services including the preparation of bidding documents associated with the implementation of these improvements. Funds for final design services are available in the annual Capital Improvement Program budget.
On April 10, 2007, the City Council authorized a professional services agreement with Moffatt & Nichol to provide engineering design and inspection services for the Pier Infrastructure Assessment Study (Study). The Study was a comprehensive inspection and condition assessment of all of the Pier’s above-water and underwater structural components. The Study provided an evaluation of the under-deck piping systems, the loading capacity of the concrete portion of the Municipal Pier, the remaining portions of the Newcomb Pier deck, the deck over the Santa Monica Aquarium, the Pier’s lighting and fire protection systems, and the furniture and fixtures of the Pier. The Study was completed and delivered in November 2008 and included recommendations for a 10-year capital improvement plan for the Santa Monica Pier. It was forwarded to Council via an Information Item on May 19, 2009.
The Study recommended two priority safety improvements to the Santa Monica Pier –the Municipal Pier structural upgrade and the implementation of an emergency gangway. The Municipal Pier structural upgrade will continue the process of upgrading the Pier to an H-20 (twenty-ton truck) capacity to provide adequate access for emergency vehicles and firefighting equipment. The Study included preliminary design details for the replacement of the existing Municipal Pier over the surf and tidal zone, which is the area approximately bordered by the high tide line on the East and the low tide line on the West. The proposed improvements include replacing the current all-timber construction with concrete piles, concrete pile caps, and timber stringers and decking. The use of concrete in this area is recommended because this portion of the Pier is over water and concrete will provide higher durability and lower maintenance in the surf zone.
The addition of an emergency evacuation gangway to the western end of the Pier was also identified in the Study as a priority. A gangway would allow the evacuation of the western portions of the Pier in the event that a fire or other emergency prevented passage on the existing Pier. The emergency gangway would be stored at deck level when not in use and would be used to load evacuees onto waiting vessels in the event of an emergency.
