The comprehensive scope of work on the NRD Habitat Restoration project at Vigor Shipyard in Seattle, Washington involved the demolition of various structures including piers, shipways, whirly cranes, and an existing substation. Following the demolition, our team meticulously addressed environmental concerns by removing contaminated sediments, allowing for their upland disposal. Clean sediment and riprap were dredged and repurposed onsite to create new intertidal habitat areas.

A critical aspect of the project involved the construction of protective measures for the newly formed slopes. Orion implemented new slope armoring, along with riprap featuring quarry spall bedding and geogrid to provide stability and longevity of the restored areas. Simultaneously, a segment of an existing pier was reconstructed utilizing new steel pile, cast-in-place concrete, and crane rails to meet the shipyard's future operational needs. Timber pinch piles were strategically driven to support underwater slopes in an area that has a building above it.

Orion successfully executed the installation of a new stormwater system. This comprehensive system included conveyance piping, catch basins, lift stations, and detention tanks as well as upgrades to an existing treatment system. This project emphasizes our commitment to responsible infrastructure development and ecological restoration.
