Y--Southwest Valley Flood Damage Reduction Project, Extension/Spillway Diversion, Bernalillo County, New Mexico

The Southwest Valley Flood Damage Reduction Project, managed by the U.S. Army Engineer District Albuquerque under solicitation W912PP-10-B-0052, involves the construction of approximately 3,000 feet of flood flow channel in Bernalillo County, New Mexico. The project scope extends from the Los Padillas Drain to the Rio Grande and includes the installation of earth lined, concrete lined, and articulated block channels. Key structural components consist of three opening concrete box culvert crossings at the Rio Grande Levee, reinforced concrete pipe siphons with concrete headwalls, and grouted riprap at inlet and outlet ends of existing drain crossings. This contract was designated as a total 8(a) set-aside for firms located in Texas, New Mexico, and Colorado. The procurement process included multiple amendments to refine technical drawings, specifications, and the proposal schedule, which detailed base bids and bid options for excavation, piping, and concrete structures. The project encompasses comprehensive civil, structural, and geotechnical works, including specific horizontal alignment for the Isleta and Los Padillas drains and the development of maintenance roads.
