About this file
This document is a set of design drawings and construction specifications for the North Rim Infrastructure Rehabilitation project at Grand Canyon National Park, a UNESCO World Heritage Site. The project focuses on Volume 2, which encompasses pipelines connecting the North Rim to the Roaring Springs Pumphouse (RSPH). The drawings, prepared by HDR Engineering, Inc. (prime) with GEI Consultants as a subconsultant, include detailed hydraulic profiles for raw and finished water systems, bore alignment and profile overviews, wellhead and drilling cellar details, and terminus and casing spacer specifications. The project involves a horizontal directional bore operation with entry and exit sites, protective matting and sandbag embankment plans, and comprehensive utility infrastructure design. Design dates are reflected as August 2026, with drawings numbered according to volume and sheet designations (e.g., 021C401, 021C502, 021C503).
Key technical specifications include casing and pipe dimensions with materials ranging from steel to various grades, design flow rates of 40 gallons per minute (GPM) through a 1,000-foot pipe section, and pump shutoff head elevation at 8,815 feet. The bore profile extends approximately 140 horizontal feet with depth considerations through multiple geological formations including Kaibab, Toroweap, and Coconino formations, with build rates specified at 3°/100 feet in certain sections. General notes emphasize contractor coordination with the National Park Service, sensitive resource area protection, and requirements for surveying borehole locations prior to drilling. The construction limits are precisely defined with northing and easting coordinates provided for all key points.
