What We Build

Full Service.
One company. One Team.

Active Construction self-performs underground utilities, site preparation, road construction, wetland mitigation, project management and site remediation services. Here is the work we put in the ground.

Roadway & Street Improvements

City streets, arterials, roundabouts, and complete-streets buildouts — HMA paving, grind-and-overlay, curb/gutter/sidewalk, ADA ramps, bike lanes, illumination, traffic signals, retaining walls, guardrail, and channelization across Pierce, King, Thurston, Kitsap, and beyond.

Site Development & Earthwork

Residential plats (27- to 174-lot), commercial site work, mass excavation, clearing/grubbing, structural fill, retaining walls, parking lots, demolition, TESC/SWPPP, and full underground utility installation for private developers, school districts, and public agencies.

Fish Passage & Stream Restoration

Fish-barrier removal, culvert replacement (CMP to box culvert), engineered log jams, levee setbacks/revetments, stream bypass and channel realignment, floodplain excavation, riparian habitat planting, and wetland creation — primarily for counties, WSDOT, and conservation districts.

Water, Sewer & Storm Utilities

Standalone wet-utility projects — water mains (4-inch through 12-inch+), sanitary sewer, force mains, storm conveyance, detention/retention systems, and culvert replacements. Often a secondary scope on roadway and site-development jobs; primary on dedicated utility extensions and upgrades.

Parks & Trails

Paved multi-use trails, picnic and pedestrian shelters, sport courts, bicycle pump tracks, community gardens, off-leash dog areas, site furnishings, fencing, irrigation, riparian planting, and environmental remediation/open-space restoration at state and county parks.

Emergency Response

Rapid-response mobilization for infrastructure failures and disaster repair — road-slump reconstruction, bridge scour repair, stream diversion, and temporary BMPs on compressed timelines.

One contract. One team. One point of accountability.

Main Street Multipurpose Path Crew Positive Feedback

ACI was recently featured in a Seattle Times article from local City of Bellevue residents that wish to acknowledge our crew’s work.
This was a challenging project with many changes to navigate but Brett and Tyler did an excellent job staying in constant communication with local residents, maintaining excellent housekeeping and pushing the project towards a successful completion. A lot of the time contractors receive bad reviews and communication regarding disruption of traffic, so it’s always nice to hear good things from the public.
Hats off to Brett and Tyler for their hard work!
You can reference the Seattle times article linked in this announcement.
