- Description
- The US Army Corps of Engineers, Walla Walla District is seeking sources for a construction project entitled, Trolley Pipe Installation at Ice Harbor, Lower Monumental and Little Goose Dams. This will be a firm fixed-price contract. Construction magnitude is between $250,000 and $500,000. The period of performance is expected to be 15 December 2009 through 28 February 2010. 100% payment bond and performance bonds will be required. Summary of Statement of Work Trolley pipes are mounted to the concrete pier noses on the upstream side of the dam, and are used in fisheries research to hold instruments which track and record fish movements through/by a dam. These pipes require schedule 40 steel, 4 inch inside diameter, painted pipe with a 1 inch slot cut the length of the pipe, with a cap welded on the bottom end. A trolley consists of a 1 inch slot cut the length of the pipe, with a cap welded at the bottom end. A trolley consists of a 3 inch diameter, schedule 40 pipe with an 8 to 12 inch piece of 1 inch outside diameter galvanized pipe welded to it. The 1 inch inside diameter pipe acts as the mounting post for the fish tracking equipment. The 3 inch trolley fits inside the 4 inch trolley pipe and the 1 inch pipe slides in the slot that is cut in the 4 inch pipe. Table 1 shows the lengths of spillway and power house pipes needed at each project location. Table 1. Recommended Lengths of 4 inch diameter trolley pipe. Abbreviations are as follows: S = Spillway pipe length; P = powerhouse pipe. Length for each of the projects powerhouses Please see attachment for Table 1. InstallationThe pipes will be mounted on the upstream face of the pier noses at each dam. This will require diving up to 120 feet in depth and boring 1 inch mounting holes into the concrete. Table 2 shows the diving depths for the power house and spillway pipes at each dam Table 2. Diving depths and mounting brackets needed for each trolley pipe on the powerhouse and spillway at each dam. The number in parenthesis is the position of the lowest mounting bracket on the respective trolley pipe. Dive depths vary due to differences in distance from the dams deck and the forebay water surface, resulting in more or less of the trolley pipe being out of the water. Please see attachment for Table 2. The spillway pipes will require seven mounting brackets with 14 mounting holes per pier nose. The elevation of the bottom end of the spillway pipes will be approximately 15-20 feet from the ogee crest. The top end of the pipe will extend to the level of the deck. The powerhouse pipes will require 12 brackets with 24 mounting holes per pier nose. The elevation of the bottom end of the power house pipes will be approximately level with the mid-point of the turbine intake, which is approximately 30-35 feet from the bottom of the intake. The top end of the power house pipes will extend to the level of the deck. The pipes require painting with a rust/wear resistant paint which is rated for underwater exposure, or powder coating with similar rust/wear specifications. In the past, trolley pipes have been built and shipped in 40 foot sections. Mounting bracket spacing is based on that assumption. Mounting brackets shall be welded to the pipe in a position that allows the trolley to be inserted into the pipe with sufficient clearance to raise and lower the tracking equipment. Mounting brackets will be welded on a 40 foot section at 3 feet, 14 feet, 26 feed and 37 feet spacing. All mounting brackets will be fabricated that allows mounting on flat or rounded pier noses. ScheduleFabrication and installation of the pipes must be completed at each dam by February 28, 2010 to be ready for equipment deployment before the spring juvenile migration. Contractor is required to follow the procedures in the Army Corps of Engineers Safety Manual, at http://www.usace.army.mil/CESO/Documents/EM385-1-1FINAL.pdf. This sources-sought announcement is a tool to identify concerns with the capability to accomplish the work. Only those firms who respond to this announcement by submitting a statement of their current or past technical experience (what the firm has done) and current or past performance (how well the firm did it) similar to or the same as the requirements stated above, will be used in the determination of whether to set aside this requirement. The North American Classification System (NAICS) Code for this project is 238190 and the associated small business size standard is $14,000,000.
