- Description
- The Sacramento District of the U.S. Army Corps of Engineers has an upcoming acquisition to establish contracts to retrofit the tainter gates at New Hogan Dam in Valley Springs, California. The New Hogan Project is located approximately 60 miles southeast of Sacramento, California and is operated and maintained by the Corps of Engineers, Sacramento district. The project includes a lake, dam and a spillway with three tainter gates. The New Hogan Project was constructed in the early 1960's. The New Hogan Dam Tainter Gate Retrofit, as originally constructed in 1963, is part of the New Hogan Dam which is rock filled structure with a separate concrete spillway structure. This dam is used for both flood control and water conservation. The crest length of the main dam is 1,935 feet at elevation 725.0 mean sea level (msl). The length of the concrete spillway structure is 142 feet with the top of the tainter gate at elevation 722.97 msl. The spillway is located approximately 600 feet south of the left abutment of the main dam and consists of a concrete structure with three 38 foot by 37 foot tainter gates. The spillway structure is approximately 142 feet long. The effective crest length is 114 feet with a crest elevation of 679.5 feet. Each of the three tainter gates at the spillway crest is 38 feet wide and 37 feet high. Embedded in concrete piers, a post-stressed anchorage system secures the trunnion 14' 6 quote mark above the bottom of the gate. The trunnion is above the theoretical flow line for a spillway flood discharge of 117,400 cfs. If this flow line is exceeded, the bottom of the gate and the trunnions will be inundated. All of these parts however, were designed to withstand this remote possibility. Twenty vertical ribs, spaced 2 feet apart, reinforce the steel face plate. Three girders support the ribs and connect through the struts to the end frames. Forces transfer through the end frames and directly to the welded steel trunnion. The bolts connecting the end frames and trunnion only maintain alignment between the two members. The bracing of the 3 girders was designed to support one half the weight of the gate, assuming one side remains supported. If one of the two lifting cables should break, the gate will twist until it jams between the piers. Bracing prevents buckling of the girders by reducing the distance between support points. The trunnion bears on a bronze bushing encased in a steel shell. The shell is fastened to the anchor member and reinforced by a heavy steel strap. End clearance between the bearing and the trunnion allows for lateral displacement of the trunnion. End clearance permits elongation due to loads and expansion from the temperature difference between the gate and concrete spillway. A post tensioned anchorage fastens each of the trunnions to the piers. It efficiently distributes forces from the tainter gate to the piers. The anchorage is comprised of 15 high strength alloy steel rods 1 quote mark in diameter. The rods are embedded into the pier 35 feet. These rods hold a short welded box trunnion girder against the pier. The trunnion assemblies are bolted to the cantilevered ends of the trunnion girders. The concrete lined chute directs spillway flows from the ogee section to the flip bucket about 214 feet downstream. There is a three span composite concrete deck and steel girder spillway bridge which was designed to carry a crane with load totaling 58 tons. The three simple spans are two at 43' 8.5 quote mark and one at 46'. The Contractor shall have experience in fabrication or repair of large Hydraulic Steel Structures such as a Tainter gate, Miter gate, or bulkhead gate and electrical and mechanical procurement and installation. The contractor shall have completed three similar projects, two of which were tainter gates, in the last seven years.

Mechanical: installing mechanical equipment including motors, speed reducers, shafting, couplings, open gearing, bearings, and large bushings in precise alignment. The offerer shall have a minimum of five (5) years of documented experience on projects installing mechanical equipment including motors, speed reducers, shafting, couplings, open gearing, bearings, and large bushings in precise alignment. The offerer shall also have completed at least one project of similar scope or replacement of hoist machinery for a large structure.
