What Quigg Bros does

Quigg Bros., Inc. is a fourth-generation, family-owned heavy civil construction company headquartered in Aberdeen, Washington, operating since 1937 with roots in Grays Harbor dating to 1897. The company delivers a multi-discipline construction portfolio spanning pile driving and cofferdam work, marine construction (tug boats, barges, derricks, precision dredging, wharf and jetty work), jetty and bankline construction backed by company-owned rock sources, road and bridge construction with a large inventory of false work and deck panels, fish passage and stream enhancement, industrial construction and maintenance, aggregate production and recycling, and marine terminal operations, plus dedicated environmental services. Customers are predominantly government and public works agencies in Washington State, including King County Parks, the Washington State Department of Natural Resources, the City of Aberdeen, and the Washington State Parks and Recreation Commission.

The business operates on a project-based contracting model, pursuing work through competitive public bidding for government clients and direct negotiation for industrial clients, with pricing quoted per project and not publicly disclosed. Capital intensity is a defining structural feature: the company maintains a substantial fleet of marine vessels, cranes, false work, deck panels, and aggregate production facilities, and owns several rock sources with a special relationship with the operator of the largest granite source in the Pacific Northwest. This vertical integration in marine and aggregate capability, combined with an EMR factor below 1.00 for over 18 years and membership in AGC, AGC of Washington, and ISNetWorld, supports prequalification for sensitive public works.

Go-to-market is direct and reputation-driven, with marketing limited to a professional website, project photo galleries, and earned media through award coverage and project announcements. Distribution is single-channel domestic field sales; there is no consumer product, software platform, app, or external investor base. The company is independently owned by the Quigg family across four generations, with third-generation President John Quigg, Secretary/Treasurer Matt Zepeda, and active fourth-generation members Charlie Quigg, Neil Quigg, and Peter Ewen in day-to-day roles.
