BREMERTON, Wash. - The new Bremerton Marina, officially opened with a grand celebration on May 31, 2008, has already received two regional awards.

In May of 2008, the Port received two awards; the first was an Outstanding Civil Engineering Achievement Award from the local chapter of the American Society of Civil Engineers, and the second was a Project Achievement Award presented by the Construction Management Association of America, Northwest Chapter.

The Outstanding Civil Engineering Achievement Award was given in recognition of the Bremerton Floating Wave Attenuator. It is a 1,440 foot-long floating concrete wave attenuator installed to expand and upgrade the Port of Bremerton’s Marina in downtown Bremerton. The 24.5-foot wide solid floating structure not only attenuates wind waves and ferry wakes but also serves as a public park, which allows non-boaters convenient and safe access to the waters of Sinclair Inlet. The design (by Art Anderson Associates) and construction of the floating wave attenuator utilized several unique elements:

1. State of the art analysis to determine attenuation performance and hydrodynamic behavior of the floating structure.

2. The use of cast-in-place ready-mixed concrete to fabricate the pontoon hull sections. The concrete mix design utilized a blend of lightweight fine aggregate imported from Colorado and normal fine aggregate.

3. Post-tensioning of the 12 individual concrete pontoon sections to create a single 1,440 long floating structure that is moored with separate mooring lines. Reid Middleton provided construction support engineering services.
