Replacement of American Canal-Upper Reach

Replacement of the American Canal-Upper Reach in El Paso, Texas General Description of the Work - The work for this project generally consists of the demolition of reinforced concrete open channel canal, and replacement with a new open canal and a reinforced concrete closed conduit flow conveyance structure. This proposed project is part of a larger project to rebuild the deteriorated, concrete-lined American Canal, which is located in El Paso, Texas. The American Canal begins at the American Diversion Dam, near the intersection of Executive Center Boulevard and West Paisano Drive (U.S. Highway 85), and extends alongside the Rio Grande for nearly 0.5 mile, where it crosses through a culvert under West Paisano Drive. After exiting this first culvert, the canal runs along the east side of highway for roughly 0.6 mile, where it crosses through a second culvert under West Paisano Drive and exits on the west side adjacent to the Rio Grande. The canal continues downstream for another 0.5 mile, at which point it connects to the Hart's Mill Sedimentation Basin, which is the beginning of the American Canal Extension, near the old West Yandell Drive overpass and the International Diversion Dam in the Rio Grande. The canal is accessible from various access points off West Paisano Drive. The American Canal is subdivided into three segments - upper (upstream), middle, and lower (downstream) segments. Each segment is separated by a highway culvert. Reconstruction of each segment will be performed separately. The work under this contract is for the second phase of the project and is limited to the reconstruction of the American Canal's upper segment only. This upper canal segment extends approximately 0.5 mile from where it begins at the diversion of American Dam and enters the first highway culvert under West Paisano Drive. The existing canal has a flow capacity of 1,200 cubic feet per second (cfs). The capacity of the new canal system will be increased to 1,535 cfs. Major Construction Tasks (1) Preparation of right of way (clearing and grubbing). (2) Construction of ramps. (3) Demolition and disposal of existing reinforced concrete canal. (4) Construction of new canal lining, cast-in-place reinforced concrete transitions, and rectangular-shape culvert sections of the canal. (5) Dewatering and possible treatment of contaminated groundwater. (6) Removal and disposal of contaminated soils and replacement with clean (non-contaminated), suitable backfill. (7) Cleaning and removing debris from jobsite. (8) Reestablishment of embankments and roadways. The magnitude of this project is between $5,000,000 and $10,000,000. Performance Period -The canal and necessary structure work for conveyance of irrigation waters shall be constructed during the non-irrigation season, which typically runs from October 15 to February 28. Only work that does not impact on the system's ability to deliver irrigation water (i.e. staging, construction/restoration of berms, fences, grounds, vegetation, etc.) may continue into the irrigation season. Solicitation, plans and specifications are expected to be posted on or about July 22, 2016 (this is a target date which may slip or change; if the solicitation is not posted on Federal Business Opportunities by July 22, 2016 that is because the solicitation is not available for posting). The solicitation will be available for a minimum of thirty (30) calendar days. This is a Presolicitation Notice. The Solicitation will include information on how to obtain the plans and specifications. All responsible sources may submit a bid which will be considered by the agency.
