North American Industry Classification System (NAICS) code: 237110 Water and Sewer Line and Related Structures

Small Business Size Standard: $45

Solicitation: The NPS anticipates issuing a Request for Proposal (RFP) in the Summer/Fall 2026. The Government intends to schedule a pre-proposal site visit prior to seasonal closure of the North Rim (typically mid-November), subject to schedule and access conditions.

Bonding: The NPS anticipates bid, performance and payment bonds will be required

Project Description:

The National Park Service (NPS) has a requirement to rehabilitate the utility infrastructure systems throughout the North

Rim developed area and at certain inner canyon sites at Grand Canyon National Park, Arizona. This project will address critical system deficiencies associated with water, wastewater, electrical, and communication systems, along with their associated equipment, components, and support structures. Infrastructure includes water (raw water, treatment, and distribution), wastewater conveyance, power and communications (standby power, overhead power, solar power, fiber communications). The project will require work at locations throughout the North Rim developed area as well as at several geographically separate locations within the inner canyon including Roaring Springs Pump House, Manzanita Use

Area and Cottonwood Campground.

A key project component includes new boreholes to be directionally drilled from the North Rim to Roaring Springs Pump

House with carrier pipes to include raw and potable waterlines. Two approximately 8-to-26-inch diameter, 9,260-feet-long boreholes will be drilled sequentially using vertical direction drilling, extending from the drill site (i.e., bore entry site) at the North Rim ballfield to the bore exit site just west of Roaring Springs Pumphouse in the inner canyon, where the borehole would daylight. The planned boreholes have a vertical length of 3,310 feet, a total measured length of 9,260 feet, and will be drilled through several Paleozoic geologic units of variable lithology with the potential for a variety of geologic risks

The purpose of this project is to provide Grand Canyon National Park with reliable water, wastewater and power systems to serve the North Rim and related inner canyon locations. Critical and obsolete aspects of these utility systems will be replaced and rehabilitated to meet code requirements. These utility systems support visitor services and administrative operations.

The North Rim is a remote, high‑elevation site, with seasonal access generally from May through October, and limited road and staging areas. Helicopter access will be required for equipment or materials transport, primarily for inner canyon construction.

The project is located at: Grand Canyon National Park, North Rim, AZ.

The construction magnitude is greater than $10M

The surrounding area is rural with limited staging located adjacent to the site. The construction site is approximately 45 miles from nearest suppliers and lodging facilities (Jacobs Lake with limited facilities) and 80 miles to Kanab UT.

The North Rim of Grand Canyon National Park generally opens to the public in mid-May and closes to the public in mid-

November each year depending on weather and road conditions, with visitor facilities typically opening in mid-May and closing in mid-October. Due to impacts from the 2025 Dragon Bravo wildfire which impacted many North Rim facilities, the NPS has not determined what services, if any, will be available to the public or for contractor use starting in 2026 and beyond.

Seasonal or other shutdowns may occur during the period of performance and winter construction may be required throughout the period of performance of this project. The Contractor may need to coordinate winter access logistics with

NPS and may be required to provide their own access to certain work locations during the winter. The successful contractor on this project will be self-reliant and able to prosecute the work with limited reliance on NPS for logistics support and site access.

Due to the project’s location in a remote but popular national park and because much of the work of this project will be performed in areas with high public visitation, difficult access and in close proximity to sensitive natural and cultural resources, this project includes many critical requirements associated with contractor operations and visitor and resource protection. Contract activities and logistics must be structured to minimize visitor impact and protective measures are required to minimize impacts on park resources. These unique project requirements combined with the project’s logistical challenges will demand careful management, scheduling and work planning and very close attention and coordination on the part of the prime contractor and all subcontractors.

Scope of Work

Water System

• Rehabilitation to the Roaring Springs Pumphouse (RSPH) to supply raw water from the Roaring Springs source

• Raw and finished water pipelines between the North Rim water storage tanks (Tank Farm) and Roaring Springs

Pumphouse for improved reliability and reduced repairs

• North Rim Water Treatment Plant (NR WTP) at the Tank Farm site to meet water quality regulatory requirements

• Treated water supply to current inner canyon potable service locations via backfeed from the North Rim Water

Treatment Plant

• Rehabilitation of raw water pipeline between Roaring Springs Cave and the RSPH

Wastewater System

• Replacement of the sewer collection system

Power System

• Additional diesel fuel storage at Power Distribution Center to receive full deliveries and provide for longer outages

• Addition of fourth standby generator at Power Distribution Center

• Replacement of transformers which have exceeded life cycle at Power Distribution Center and throughout North

Rim campus

• Replacement of junction boxes and shunt reactors in poor condition throughout North Rim campus

• Replacement of overhead power from North Rim to RSPH to increase life expectancy and reliability

• Replacement of underground power from RSPH to Manzanita
