Ngwsp block 2-3 HDD

The Department of the Interior Bureau of Reclamation is seeking contractors for the Navajo-Gallup Water Supply Project (NGWSP) Block 2-3 Horizontal Directional Drilling project, which involves constructing approximately 280 miles of water transmission pipeline with multiple HDD crossings at four specific locations near Shiprock, New Mexico. The project requires horizontal directional drilling techniques to install 42-inch and 36-inch buried water transmission pipelines at critical river crossings including Shumway Arroyo, San Juan River, Nenahnezad Bluff, and Chaco River. Contractors must demonstrate experience with complex geological conditions involving alluvium, sandstone, and shale formations, and must submit comprehensive quality control and surveying plans prior to work commencement. The solicitation will use a best value evaluation process in accordance with FAR Part 15, assessing technical quality, schedule adherence, management capabilities, cost, and safety performance. A pre-award site visit is planned for approximately November 5, 2025, with the solicitation expected to be released around October 29, 2025, though the solicitation number has been changed from 140R4025R0027 to 140R4026R0002.

This procurement is anticipated to be a small business set-aside under NAICS code 237110 with a small business size standard of $45.0 million. The estimated contract value ranges between $30-60 million, with no current incumbent or contractor information provided in the notice. The project encompasses multiple HDD bore lengths ranging from approximately 2,000 to 3,300 linear feet across different reaches, with pricing structured by linear foot for pilot bore, HDD installation, and conductor casing installation. Contractors must provide a 20% bid guarantee and 100% payment and performance bonds, and must be registered in the System for Award Management (SAM). The work involves traversing Navajo Nation and Jicarilla Indian Reservation lands in New Mexico, requiring careful attention to environmental considerations and cultural resource protections throughout the horizontal directional drilling process.
