- Description
- The two-phase selection procedures are described in FAR 36.3. The contracting officer with involvement of the PDT shall make a determination that the design-build procedures are appropriate, using the criteria delineated in FAR 36.301 (b). If appropriate, the contracting officer should use the two-phase selection procedures, unless another design-build acquisition procedure authorized by law is used. NOAA Fisheries and other regional fish managers use Passive Integrated Transponder (PIT) Tag data to track fish movement of anadromous species as they go downstream in their outmigration and as they come back upstream heading to their spawning grounds. Information collected can be used to estimate bypass passage rates, run timing, survival and smolt to adult return rates as well as evaluate the effects of project operations. The estimated construction cost limitation (combined design and construction costs) for this project is $6,000,000.00. Currently, spillway bay one functions as the surface passage route at Lower Granite and passes an average of 75% of those fish passing over all eight of the spillway bays. The Corps of Engineers does not have a way to collect PIT Tag data from outmigrating juvenile salmonids and steelhead passing over these spillways. Studies six to ten years ago indicated an average of 65% of fish passing the dam on their way downstream passed over the spillway and, as a result, were undetected by existing monitoring systems. In an attempt to collect PIT Tag information from the fish passing over the spillway at Lower Granite Dam, the Corps of Engineers intends to install a monitoring system in spillway bay one. The contractor would design, fabricate, and place a steel bulkhead on the downstream end of the spill bay one deflector. The bulkhead would span from pier to pier across the spill bay (from several feet below the end of deflector (elevation ≅630 ft) to high tailwater elevation (≅642 feet). The bulkhead would isolate the construction area in the spill bay from the stilling basin. The bulkhead design would be stamped by a licensed professional engineer. The bulkhead would isolate the work area from about 10-12 feet of water in the stilling basin and would need to seal tightly at the base to minimize leakage into the work area. The contractor may use a barge mounted crane moored in the stilling basin outside the work area to set the bulkhead and support the construction work. Divers may need to assist with bulkhead placement to ensure correct positioning and establish an effective seal between the bulkhead and the existing spillway deflector surface. Once the bulkhead is in place, the area between the steel bulkhead and the spillway surface or the existing spillway piers would be dewatered. Work on the spillway chute and deflector would then be accomplished in the dry. Some water leakage is usually present, so pumping water may be required throughout the construction period. The contractor may use any combination of methods such as saw cutting, drilling, splitting and/or high pressure water blasting to remove some concrete from the face of the existing spillway, exposing the rebar and leaving a roughened surface for placement of the new concrete forming the flatter spillway chute and modified spill deflector. Estimated concrete removal is 150 cy. The removed concrete would be captured and not allowed to fall into the tailrace pool. During concrete cutting/removal operations, all process water and waste material would be collected for treatment and upland disposal. Construction materials or fluids are not allowed to come into contact with Snake River water. The work may include drilling and grouting concrete anchors into the face of the spillway followed by installation of reinforcing steel. The contractor place concrete for the final spillway chute and spill deflector surfaces. The contractor would have to place the concrete within a limited work window, and would be required to demonstrate concrete placement on a sloped surface. All seepage water and other water from construction operations would be removed from the work area for appropriate treatment. Should the need arise to spill water from other bays during construction, any support barges outside of the dry work area would need to be removed. Depending on levels of spill, construction may continue or be halted depending on the risk to workers in proximity to the river tailrace area. A series of pass-over antennas (GFE) would be installed within the added spillway ogee surface. The antennae project an electromagnetic field up through the ogee concrete surface and spillway flow. PIT Tag data is collected from tagged fish as they pass over the antennas. Multiple antennas would be installed by the contractor and covered with a cap to isolate them from spillway flow during spillway operation. Aluminum shields would be fabricated and installed by the contractor beneath the antenna to isolate their field from magnetic elements in the spillway. If concrete is used; new concrete placement above the antennae requires non-metallic rebar and non-magnetic aggregate. Associated cabling and conduit would be installed in the spillway surface to connect the antennaes to a climate controlled shelter provided by the contractor and ground the antennae and shields. The electrical shelter would be located adjacent to spillbay one. Communications cable would include copper antenna cables between the antennas and transceivers (GFE) and fiber optic cables from the transceivers back to the existing data system in the juvenile fish facility. Arbitrary dates for scheduling purposes only.
