Final Design and Contractor Selection Following completion of the permitting process, led by the US Navy and US Fish and Wildlife Service, NWSF contracted with Coastal Geologic Services to develop the final design and refine estimated quantities to be removed. NWSF developed bid documents and project specifications and advertised the project through legal notices in the Whidbey News Times/South Whidbey Record and through Skagit Publishing. Bid information was also posted and updated as needed on Builders Exchange of Washington (31TUwww.bxwa.comU31T), an on-line plan center. Bid advertisements included a project summary, pre-bid meeting information, and instructions for bidding. A mandatory pre-bid meeting was held with potential contractors on site August 15, 2018. Four contractors submitted bids. The bid opening was held on August 28, 2018. Under Washington State public works laws, the use of public funding requires that contracts are awarded to the qualified lowest bidder. Qualifications are defined in the bid documents to ensure bidders and contractors have successfully completed projects that incorporated similar scope, habitats, permitting requirements, size and value, and methods. Neptune Marine, Inc of Anacortes, Washington was selected as the qualified lowest bidder. NWSF received four bids ranging from $206,153 to a high bid of $454,338. The engineer’s estimate for the work was $210,314. Contract documents were developed between NWSF and Neptune Marine in anticipation of September 25, 2018 start date. Construction Implementation Neptune accessed and transported all equipment and materials on and off site using a landing craft. Heavy equipment and dump trucks were offloaded onto the beach and worked at lower tidal cycles to remove debris, whereas higher tides were required for loading onto the landing craft for transport off site. This resulted in gaps in construction timing to accommodate tidal cycles. Neptune worked for two weeks, were off for two, and then completed the work. Neptune began with stacking of large rock, smaller angular rock, and concrete bags into distinct piles at strategic locations along the shoreline to allow for the landing craft and equipment to minimize movement along one line parallel to shore and maintain only one or two paths perpendicular to shore as required in the permits. Once most of the rock and concrete was piled up, they worked on removing the tire wall and then the creosote walls. Removal work alternated with offloading as tides allowed. Final cleanup included removal of remaining angular rock large and small, replacement of large woody debris that was moved to allow for work to occur, and a final grading of the beach to minimize tire tracks from equipment and ensure no holes remained from rock or debris removal. For offloading, dump trucks were staged on the beach traveling across steel plates to eliminate sinking into the sediment and to displace the weight of the trucks and loads. Trucks were loaded with materials, then driven onto the landing craft. The Navy base seaplane ramps were used to offload trucks which then transported materials to a local pit near Oak Harbor. All rock and concrete were sold or given back to the pit for reuse in exchange for use of the site. Tires were processed for recycling or disposal as was the miscellaneous metal and other debris from the gabion protection method. Creosote-treated materials were reprocessed after initial offloading and sent via rail to the Allied Waste facility in eastern Washington where creosote-treated wood is approved for disposal. Construction oversight was provided by Coastal Geologic Services and Northwest Straits Foundation. Oversight consisted of managing for permit compliance (NWSF) and ensuring materials were removed in the quantities and manner expected. Neptune proved to be efficient and thorough in their work. Construction and all demobilization of equipment and materials was completed on October 15, 2018. Results: Project outcomes 21.34 tons of creosote-treated wood removed 36.53 tons of tires removed 1,511 tons of angular rock and armor stone removed 304.96 tons of concrete bags removed
