Replace North Rim Potable Water Distribution System at Grand Canyon National Park

The Department of the Interior, through the NPS DSC Contracting Services Division, issued solicitation 140P2018R0076 for the replacement of the North Rim potable water distribution system at Grand Canyon National Park, identified as Project GRCA 160057. This Phase 2 project involves the replacement of underground water distribution lines with an estimated price range between 5,000,000 and 10,000,000 dollars. The construction is scheduled for a duration of 244 days, with specific considerations for a winter shutdown period from October 15 to April 15. The scope of work is supported by 134 pages of technical drawings covering existing conditions, erosion control, and specific bid options for the Lodge, Campground, EDR, and WWTP-Admin areas. The procurement process included multiple amendments to address contractor inquiries and refine technical specifications, including revisions to construction drawings and the provision of native format files. Key project constraints include strict adherence to the Mexican Spotted Owl protection activity center restrictions from August 1 to February 28 and the requirement for contractors to field verify all utility locations and elevation discrepancies. Labor for the project is governed by the Coconino County wage determination for heavy construction. The final proposal deadline was established as July 20, 2018, with the contract award anticipated for early August 2018.
