Services
Trenchless Technology
Our trenchless engineering services utilize advanced methods like CIPP lining, pipe bursting, and horizontal directional drilling to repair underground utilities without disruptive excavation. This approach reduces surface damage, lowers costs, and accelerates project timelines while maintaining structural integrity. We specialize in adapting these technologies to Alaska's challenging geotechnical conditions.
Condition Assessments
We conduct comprehensive evaluations of existing utility systems using CCTV inspections and physical assessments to identify failure mechanisms. Our team has analyzed over 600,000 feet of Alaskan sewer and water mains, providing detailed reports with repair recommendations and cost estimates for municipalities and private clients.
Pipeline Assessment
Our certified engineers perform detailed pipeline assessments using closed-circuit television cameras and PACP-certified evaluation methods. This process identifies structural defects, corrosion, and flow issues in sewer and water systems, forming the basis for targeted rehabilitation strategies that maximize infrastructure lifespan.
Construction Management
We provide full-cycle construction administration services including quality control, submittal reviews, and stakeholder coordination. Our team ensures compliance with design specifications during implementation, managing over 80% of our design projects through successful completion while maintaining open communication between all project parties.
Horizontal Directional Drilling
Our HDD solutions enable efficient pipeline installation beneath obstacles like rivers, roads, and airport runways. We've successfully completed projects in challenging Alaskan conditions, including the Anchorage Airport water main installation, using specialized equipment and geotechnical analysis to ensure precise, minimally invasive pipeline placement.
