This document contains details for a federal solicitation for design-build services. The United States Section of the International Boundary and Water Commission is seeking proposals for the design and construction of rehabilitation improvements to the Rio Grande levee at the Edinburg Pump Station in Hidalgo County, Texas. The proposed project includes design and construction of approximately 800 linear feet of levee improvements such as earthen embankment, concrete floodwalls, and associated ramps. The design will include analysis of the existing levee for seepage remediation and raising the top of levee as needed, along with additional geotechnical investigations and assessment of structures within the levee. Major construction efforts include preparing right-of-way, removing existing material, levee widening, erosion control, installing new sections of floodwall with bollard walls, constructing floodwall foundations, removing and replacing an existing gatewell structure, backfilling and grading embankment material, installing an aggregate roadway surface, removing and replacing fencing, and revegetation. Interested parties should review the associated documents for additional requirement details.
