Bonneville Dam PIT Tag

This project required the installation and removal of a temporary contractor-designed sheet pile cofferdam to facilitate the removal of a 40’ portion of the Bonneville Powerhouse II Corner Fish Collection System. The largest fish-counting antenna of its kind was then installed during a very short in-water-work period. Slayden was able to overcome a significant amount of high water conditions and meet the Owner’s power generation/fish passage needs. Formal partnering sessions were held during the contract and were facilitated by Mr. Bob Couch, the US Army Corp of Engineers, Portland District Chief of Construction.

The project required coordination of multiple regulatory agencies, the Owner, and their multiple operators. This project also included the coordination of transporting and installing the Government furnished multi-million dollar antenna equipment with the Government suppliers. Several significant design changes occurred which required design modification by Slayden, the Army Corp of Engineers, and the equipment suppliers. The partnering efforts throughout this project allowed for the project to meet the schedule and exceed the results of the fish-counting antenna while working through adverse weather and flood conditions on the Columbia River.

Management Skills that Help Reduce Costs

"We have been impressed with their management skills, starting with preconstruction where they performed value engineering that reduced costs, lead procurement with detailed bid packages that brought our project qualified subcontractors and manufacturers and produced a schedule that would get our project completed on time. Slayden has continued this into the construction phase by managing the work to stay on schedule."
