Description

This sources sought notice seeks information on the capability and availability of potential contractors to supply and install the below described product at the John Day Lock and Dam Project, Sherman County, Oregon. This is a sources sought synopsis and is not a solicitation. This notice does not constitute any commitment on the part of the government, and no contract will be awarded as a result of this notice. The purpose of this notice is to ascertain whether a product with the salient characteristics described below is available from only one source or supplier with unique capabilities. The Government may use responses to this sources sought synopsis to make an appropriate acquisition decision for this project. Response to this notice would not need to provide a product, but a solution, that would be an approved equal to the contemplated product described below. The entirety of the scope described below is important. Offerors providing only an aspect of the scope would need to team with a partner to provide a solution. Responses should come in the form of a cut sheet or white paper with sufficient detail to provide an equally effective and cost conscious alternative to the product/solution described below. 30 days are provided to supply a response. Point of Contact for this notice is Jeffrey S. Renner, Contract Specialist, (503) 808-4630. ------------------------------------------------------------------------------------ The U.S. Army Corps of Engineers, Portland District is seeking sources for a project to repair failed monolith joint waterstops at John Day Dam, on the Columbia River. The project would involve drilling a near vertical 6 quote mark diameter hole that straddles the monolith joint starting at the top deck of the dam and extending through the entire structure into the bedrock below and filling the drilled hole with expanding grout to restore the waterstop. The tolerance for deviation from vertical is 0.1 degree for the drilled hole. At several times throughout the drilling process, the progress of the drilled hole will be checked to ensure the monolith joint is contained within the drilled area. Where the drilled hole is near the top of dam, the hole will be monitored visually. When a visual inspection of the drilled hole is no longer possible, the Contractor will be required to utilize a down-hole camera for inspection/monitoring purposes. A permanent video record of the drilled hole will need to be provided to the Government as part of the project. As part of the drilling activities, the driller will be expected to capture, remove, and dispose of all tailings, air, water, and dust created during drilling operations. After completion of the drilled hole and verification that the monolith joint is contained within the hole for the entire length of the joint, the Contractor will insert an expanding grout into the hole to restore the waterstop. Upon contact with water, the grout would begin to expand, eventually filling the entire void space of the hole. Additionally, the product would need to be able to expand and contract yearly as the monoliths shrink and swell with temperature changes. In order to insure that the entire drilled hole is filled, the product will need to be a solid product at the time it is placed into the hole. This will provide a guarantee that the entire length of the drilled hole is completely filled with the waterstop product. The product should be solid cylinders cut to a manageable length for installation. The waterstop cylinders need to have the following physical and material properties: Specific gravity above 1.04. Expansion pressure between 250 and 450 psi at full depth. Unrestrained expansion diameter of 1.5 times the original cylinder. Service temperature range between 30 and 70 degrees F. Durometer hardness shore A scale A30. Less than 0.05 percent air entrainment. Confined compression strength over 900 psi. Cylinder diameter 5 inches with a 5% tolerance. Additionally, the waterstop product manufacturer needs to have 5 years of experience performing waterstop remediation with 3 successful applications of the proposed approach at a depth that exceeds 100 feet below water.
