Past Performance

Marble Beach: This project involved restoration of the shoreline in a highly culturally sensitive area where erosion was ongoing.  The project was approx. 600’ long and 140’ in depth.  All access was via barges including equipment delivery, personnel delivery and all material deliveries.  Barges were loaded 5 miles downstream of the project location at a public boat launch.  A barge loading facility was constructed at the boat launch while maintaining public access.  Materials included 6000 tons of riprap, 2500 tons of quarry spalls, 900 lineal feet of structural retaining wall, topsoil and other misc. materials.

This area was known to be a Native American burial ground with human remains exposed.  We were not allowed to disturb the ground surface in any way.  All equipment worked off of equipment mats and barges in order to not disturb the ground surface until sufficient material was placed to protect the ground. 

Humboldt Jetty:  S.E.A independently reconstructed the Humboldt jetty and the jetty concrete cap which had endured years of storm damage. Jetty work consisted of placing and interlocking stone ranging from 8 to 25 tons in order to repair the jetty prism, as well as pouring over 3000 yards of two foot cap on top of the jetty. 

Heise Roberts Levee: This project was performed for the US Army Corps of Engineers in Eastern Idaho along multiple locations of the Snake River, both publicly and privately owned.  S.E.A. was able to coordinate with all property owners and government agencies in order to mitigate any damages to the land.  Work on this project included mining, sorting, transporting and placing over 23,000 cubic yards of material.

Kachess Dam Modifications Phase-1: In efforts to move forward with the Dam Modification plans, S.E.A. Construction completed plans of building an access road and installing a box culvert for the first phase. An additional site staging area was created to assist in the future. The first phase included hauling over 10,000 tons of crushed rock and 20,000 CY of excavation, the removal of more than 500 20" DBH logs, and 50 logs with root wads. They were then hauled to the forest service location to maintain a tidy and safe environment for workers and the wildlife.   

MCR Cape Disappointment Erosion Repair: S.E.A. Construction hauled over 6,000 tons of riprap and placed for emergency erosion control at the Cape Disappointment Coast Guard Station. There was active erosion that required quick response to protect the coast guard station. The riprap was obtained from Portuguese Point Quarry, owned and operated by S.E.A. Construction to provide quality rock for a variety of clients. Despite adverse winter conditions, the work was completed in a fast and timely manner. 

Point Chehalis Revetment Repair FY18: This project was performed for the US Army Corps of Engineers in Westport, WA and included the repair of 900' of existing revetment. Work included procurement, delivery, and placement of new under layer filter stone, core/chinking material, armor stone, and re-working/relocating existing relic armor stone as needed from leeside of the revetment.

Soledad WWTP Levee Repair Site 2, 3 & 4: S.E.A. Construction repaired the Soledad WWTP levee in Monterey County after it sustained localized damage following the atmospheric river system storms in 2023. The repair included excavation, subgrade preparation, compaction, placement of bedding material and rock soil protection (RSP). This project consisted of three separate repair areas each with unique challenges to successfully execute. S.E.A. was successful in completing the project within its tight deadline of 39 days, including preparing and submitting all submittals, mobilizing, completing all work, and demobilizing. 

Quillayute Rialto Revetment Repair: S.E.A. Construction hauled and placed 6,000 tons of armor stone to restore a section of the jetty that has sustained severe damage from the winter storms. Due to the extent of the damage and the need to protect the town of La Push, rapid response and efficient execution were critical. Despite challenging winter conditions, the work was completed safely and within the contracted timeframe.
