Excavation and underground utilities
We dig the hole, hold it open, and put in everything that goes underground: storm, sewer, water and power. One subcontractor from the first silt fence to the last patch of asphalt, in Seattle, Mercer Island, Bellevue, Kirkland and the cities around them.
What we do
Everything below grade, on site and in the street
General contractors bring us in for the dirt and keep us for the pipe, on private property and in the public right of way. One subcontractor for both means one contract, one schedule, one set of trucks and nobody arguing over who owns the trench.
Excavation and shoring support
Mass excavation, structural excavation and subgrade prep, export and import, and digging alongside the shoring crew.
Storm drainage
Storm mains, detention, infiltration, dispersion, catch basins, downspout tightlines and footing drains.
Sewer
Sewer mains, manholes, side sewers and pipe lining.
Water
Water mains, hydrants, valves, fire and domestic water services.
Power and communications
Primary power duct banks and vaults are a specialty. Secondary power and communications too, all to utility standards.
Demolition and restoration
Structures and site concrete out at the start. Curb, sidewalk and asphalt back at the end.
CAD Truck, on our jobs and for hire
Our CAD Truck (conveyor aggregate delivery) places rock, sand and soil where a dump truck cannot reach. We run it on our own projects and hire it out as a stand-alone service.
How we work
We tell you what the drawings don’t
Before we price a job we work out how it will actually get built, step by step. When a duct bank will not fit the way it is drawn, or a pipe runs close enough to undermine a foundation, we say so in the bid and offer a way through it.
Then we write the scope in plain language, in the order the work will happen, and go over it with you before anything is signed. Most of our customers have worked with us for ten to twenty years. That is what we want with every new customer.
Customers tell us this is why they call. On one recent job, checking the survey against what was actually in the ground showed that a storm main the city had required was never needed. It came out of the design. Read how that happened.
