Round Butte Dam Hydro Project Selective Water Withdrawal Structure
Portland General Electric
In 2007, Portland General Electric (PGE) and the Warm Springs Tribe of Indians began work on the latest improvements to the 40 year old Pelton Round Butte Dam Hydroelectric project. The objective was to construct a $130M facility that would meet the tightening regulatory requirements under their federal operating license. This one-of-a-kind project is known as the Selective Water Withdrawal (SWW) facility, and was completed in Spring 2009.
The SWW is a 260 foot tall, 6.5M lb structure, built of steel and concrete in four major components: the selective water bottom (SWB), the vertical flow conduit (VFC), the selective water top (SWT), and the fish transfer facility (FTF). Due to the size and nature of the project, the components were built independently in the water. The SWT and FTF are floating structures.
The different types of equipment that K&N provided on this project are as unique as the project itself. Cranes, compressed air systems, process control systems, and hydraulic gates located 250 feet below the lake surface are just a few of the distinctive features that K&N was responsible for.
The SWW will modify the surface currents in Lake Billy Chinook to mimic the downstream flow of the three contributing rivers in order to aid fish migration. The SWW is designed to pass the entire flow of the Deschutes and Metolius Rivers through the top (SWT) structure. The major objectives of this project are to reorient the surface currents toward the dam, safely capture migrating salmonids, and manage downstream water quality during seasonal discharge events. This will all be accomplished while meeting discharge permit regulations and maintaining hydroelectric generation capacity. This project stands as the largest hydro project contained entirely within the state of Oregon.

Post Street Substation Install Reactor and Switchgear Floor
Avista Corp.
This project had many challenges: it was a fast track project, performed in a dangerous electrical environment, requiring the incorporation of new structural components into a historical building and all this without interrupting the electrical power supply to the Downtown Spokane area. We were contracted to fabricate and install a new flooring system incorporating structural fiberglass and steel components. All work, including change orders, was completed within the schedule. Changes were minor and resulted from differing site conditions. A universal 3-dimensional drafting program was utilized by the design department to compile the details of materials provided from all the various suppliers. This assured a quality of detail that was outstanding and very necessary to the quick start-up and completion of the project. A sample detail is shown.

Cougar Dam Bridge Crane Rerate
U.S.A.C.E. Portland District
This project required the retrofit of controls and equipment for rerating the bridge crane from 60T capacity to 62.5T capacity. Provided mechanical, structural and electrical modifications as follows: perform pre-rehabilitation inspection and report, remove all power and control systems including motors, drive systems, conduit, and wiring, and remove the back panels in existing control cabinets leaving the cabinets to be re-used. Design, fabricate and install new master switch console. Design, furnish, and install AC variable frequency vector drives, install dynamic braking resistors and isolation transformers, install replacement AC induction hoist motors, bridge and trolley brake motors (25HP, 10HP and .75 HP), main line contactor, main circuit breaker, cable track system, control relays, speed encoders, brake rectifiers. Included in the modernization were couplings, alignment, electrical buss guard and hook safety latches. Performed structural analysis to verify adequacy of walkway to support additional loading, and to determine method of spreading test loads on erection bay floor. Final acceptance tests, including load test, and operation and maintenance training were provided. Final submittals included as-built drawings and operation and maintenance manuals.
