Stop log replacement, Gilchrist dam

The project required replacing dam flashboards without draining the lake. Pacific Underwater Construction (PUC), under the leadership of Dan Smith, provided the answer. His dive team helped to effectively remove and replace flashboards while maintaining the lake’s water surface and the plant’s production. Dan had the tools for every approach used to preforming underwater demolition and reconstruction. We could not have completed the work without PUC and Dan.

Power Plant Inspection Carmen Reservior

Pacific Underwater Construction was of good value during runner inspections of our hydropower plant. PUC was responsive with EWEB requests for certifications and safety plans and they were helpful during discussions to develop a realistic inspection plan. During implementation, the dive crew adapted well to unexpected conditions and worked well with EWEB inspectors to figure out the best ways to accomplish the inspection goals with the tools available. I would consider PUC for future underwater work.

Between the years of 2001 and 2003, Pacific Underwater Construction and its owners; Dan Smith and Robert Waterbury were engaged in the cleaning and inspection of ASPA’s 1,000,000 gallon above ground potable water storage tanks.
The scope of work for this included vacuuming and removal of all debris and sediment up to 4” thick, digital still photography, video documentation and non-destructive testing where applicable.
They followed AWWA standard M42 and C652-92 and ADC (Association of Diving Contractors) Standard 11 “Commercial Diving in Potable Water Facilities” as being more stringent that the current ANSI/AWWA standards.
Pacific Underwater Construction exceeded our expectations in both the tank cleaning and inspection reporting. We not only intend to utilize their services for all of our future diving and inspection needs, we would be pleased to recommend them as an asset to any potable water facility.
