  • From providing detailed engineering design to designing site-specific construction aids, our long history has taught us that each construction project has its own set of unique challenges.

    We have developed the necessary means to be successful: an understanding of the technical and operational aspects of the project, close collaboration between the Owner, Contractor and Engineer, and a seasoned team that understands the administrative aspects of working with the Corps of Engineers. Every project is distinctive and this is where we excel by understanding the needs of all team members, and providing timely support.

    Coffman has provided construction support engineering services to multiple contractors in the Pacific Northwest Reservoir System. At the Lower Granite Juvenile Fish Bypass project, we have designed stoplogs, custom temporary shoring, a steel bulkhead/caisson, temporary drill rig platform over the tailrace, and fall protection systems. We have also designed multiple construction aids such as tainter gate jacking systems to support trunnion replacement, and temporary cofferdams to support breaching a dam in Alaska for fish migration. In addition, we have extensive experience in mechanical and electrical system design for cranes, drive systems and hoists.
