Underground Utilities

Water, Sewer, & Storm

Underground utility installation demands precision, experience, and accountability. For more than 30 years, OSG Dozing has installed storm drainage, sanitary sewer, water distribution, fire protection, and infiltration systems for commercial, public, tribal, and industrial projects throughout the South Puget Sound region. We self-perform every phase of utility installation, eliminating subcontractor handoffs and providing a single point of responsibility from excavation through final restoration.

Our crews are trained to OSHA excavation and shoring standards and approach every project with detailed planning, verified utility locates, and a strong commitment to safety and quality. By combining experienced field crews with modern construction technology, digital project tracking, and precise layout tools, we improve coordination, accuracy, and efficiency throughout the installation process. By self-performing both earthwork and underground utilities, we streamline project sequencing, reduce coordination issues, and help keep schedules on track. The result is reliable infrastructure, efficient execution, and installations that pass inspection and perform as designed.
