Waterfront Infrastructure

Art Anderson Associates contracted with Winzler & Kelly as the lead design consultant for the overwater portion of this $13-million combined passenger ferry maintenance and terminal facility. The ferry maintenance and terminal facility project is an adaptive reuse of former U.S. Naval Shipyard Facility Mare Island. We provided concept and preliminary designs for the POF terminal and maintenance facilities.

The current phase of the project involves development of final designs and specifications for waterfront facilities and the barge and float structures. Art Anderson Associates is developing designs and specifications for the barge structure, potable water, sewage, lube oil, fueling, fire suppression, compressed air, urea, HVAC and electrical systems. Other work includes naval architectural calculations and hydrodynamic analysis of the service barge.

We are also working on structural calculations, connection and transfer span details and structural and mechanical specifications for the terminal portion of the project. The terminal function of the facility requires segregation of passengers from industrial activities, for both safety and Homeland Security requirements. The terminal function also requires ADA accessibility for passenger access, and operational flexibility to alternate slip usage for four slips, from terminal operations to maintenance operations and back again during any given shift. Art Anderson Associates personnel helped develop the required permit drawings and environmental documentation for design and construction, ensuring an environmentally sound facility.

Art Anderson Associates is participating in the largest tidal wetland restoration project on the west coast. About 85% of these historic marshes were lost in the last century due to urbanization or being diked off for salt production. In 2003, the US Fish and Wildlife Service and Department of Fish and Game acquired 15,000 acres of these salt ponds for restoration, an area the size of Manhattan. Part of the restoration plan involves breaching levees to allow tides to flow back into the ponds, which will allow them to become natural marshlands once again. While this will do much to restore habitat, it presents challenges for flood control.

Our scope of work on this design-build project involves design development and construction documents for flash weirs and water control structures at the Ravenswood Pond SF2. This 240-acre pond will be reconfigured to create islands for nesting birds and shallow water habitat for shorebird foraging. Two water control structures, two steel-frame wildlife viewing platforms, and numerous berms and islands will be constructed, in addition to raising levees by 1-2 feet. The water control structures are being constructed to achieve target water depths, adequate flushing to ensure water quality, protecting the perimeter levee and bike path from flooding and habitat management flexibility.

We are also working with the contractor, Triton Marine Construction, to identify and capitalize on value engineering opportunities. Some of these opportunities have included substituting recycled concrete as fill, substituting a wood valve control structure for a concrete vault, and using precast, prestressed concrete piles instead of plastic-coated wood piles. So far in the project, we've identified $135,000 in project cost savings using value engineering.

Art Anderson Associates provided comprehensive design and construction services for the expansion of the Port of Bremerton's marina on the Bremerton waterfront. The $34 million project expanded the marina by approximately 300 berths and incorporated an award-winning breakwater system. We provided full civil, structural, mechanical and electrical engineering design; landside and naval architecture; and bid/construction support services for of all elements of the project, including the marina floats, repositioning of the USS Turner Joy, passenger ferry terminal improvements and the primary element of the breakwater system, a state-of-the-art floating concrete structure that is approximately 8,000 long tons and over 1,400 feet in length.

The main breakwater consists of twelve precast bodies constructed of high-performance, lightweight concrete, independently post-tensioned and enabling rigid connections that allow the breakwater to behave as a single structure. The design was developed as a result of extensive physical and numerical modeling, and is protects against both wind and the long-period wake waves of passing ferry traffic. The project has already received accolades, in large part due to the accomplishments of the floating breakwater design. It won the Outstanding Civil Engineering Achievement Award from the American Society of Civil Engineers (ASCE) Seattle Section and ASCE Region 8, and is a nominee for the national Outstanding Civil Engineering Achievement Award.

Art Anderson Associates provided all overwater design for the Port Orchard Intermodal Terminal, which includes the design of a new passenger only ferry terminal and transit transfer facility that is accessible to the handicapped.  The terminal serves Kitsap Transit's Bremerton-Port Orchard passenger ferry route, and is the berthing location for the agency's ferries and Kitsap Harbor Tours vessels.

The concept design phase included the selection of float and pier types, float moorage systems and access to the floats and boats. Constraints included minimizing shading of the water, providing access through a 20-foot tidal range to people who have difficulty with stairs or steep ramps, waters unprotected from the wind (from the north) and the ability to build the facility without shutting down ferry service or impacting the adjoining guest moorage.

The Port Orchard ferry has no terminal employees, so access had to be provided without assistance at all tidal ranges. A system of ramps and an elevator were both studied as a means of providing handicap access with the elevator being viewed as far superior to the ramps. Follow-on work included a retrofit of the terminal's fendering system to reduce wear and tear on the historic ferry Carlisle II.
