Pile Driving Sheet Pile with Limited Access

Our client in Port Angeles suffered a landslide due to improperly managed stormwater pipes and heavy rains.

We used our micro-excavator, along with our […]

Fort Worden State Park Sand Dunes

Our crew worked an interesting project at Fort Worden State Park in Port Townsend. The critically imperiled sand-verbena moth (Copablepharon fuscum) uses the yellow sand verbena (Abronia latifolia) for 100% of it’s life cycle.

The second parcel, a 20-acre forested wetland near Uncas Creek in Jefferson […]

Live Stakes on Landslide in Agnew

Our crew rappelled down a large landslide headscarp and installed hundreds of live stakes. We then hydroseeded the area and placed hay to provide some protection and drought buffering.

WSDOT I-5 Pole Inspections in Tacoma

Our utility inspectors tested luminaire poles on WA Interstate 5 in Tacoma using non-destructive methods.
