Nogales IOI Rehabilitation Phases 4&5

Pre-Solicitation Notice

General Description of Work The United States Section of the International Boundary and Water Commission (USIBWC) is issuing a solicitation (negotiated) for the purpose of rehabilitating approximately 18,009 linear feet of the existing sewer pipeline known as the International Outfall Interceptor (IOI) in Nogales, Arizona.

The existing sewer pipeline was installed between 1970 and1971 and is comprised of unlined, reinforced and unreinforced concrete pipe that ranges in size between 24 inches and 42 inches in diameter. The Trunkline extends approximately 8,146 linear feet from Manhole No. 1 at the United States/Mexico border to almost Manhole No. 27, from which the IOI begins and extends about 38,290 linear feet to Manhole No. 99 at the Nogales International Wastewater Treatment Plant (NIWTP). The pipeline is approximately 46,436 linear feet in total length and has over one-hundred (100) manholes within its alignment. Currently, domestic and industrial wastewater generated in Nogales, Sonora is conveyed north through the main collector line in Mexico and across the border into Nogales, Arizona, where Mexican wastewater is eventually combined with Arizona wastewater in the Trunkline and the IOI for treatment at the NIWTP and discharge into the Santa Cruz River.

The rehabilitation of the Trunkline and IOI is subdivided in to five phases. The work under this Contract is limited to the Phases 4 and 5 of the projects within the IOI segment only and the pipe size of 30 inches in diameter. Phase 4 extends from Manhole No. 51 to Manhole No. 66 and is approximately 8,065 linear feet with 18 manholes requiring rehabilitation within its alignment.

Phase 5 extends from Manhole No. 66 to Manhole No. 85 and is approximately 9,944 linear feet with 18 existing manholes requiring rehabilitation within its alignment.

The work is located in Santa Cruz County, Arizona. A site visit date will be listed in the solicitation. The work will be performed under NAICS Code 237110. The contract will be firm-fixed price. This requirement will be competed as full and open with NO set-aside.

Major Construction Tasks The major construction efforts for rehabilitation include the following tasks:

1. Bypass pumping to maintain sewerage conveyance during rehabilitation;

2. Sewer line cleaning;

3. Television inspection of sewer line;

4. Installation of Cured-in-Place Pipe (CIPP);

5. Installation of Protective Lining Systems in concrete manholes;

6. Rehabilitation of manholes using Carbon Fiber Composite;

7. Demolition of existing sanitary sewer manholes;

8. Installation of new sanitary sewer manholes; and

9. Raising of existing manholes to grade by the use of grade rings or new precast concrete manhole sections.

The magnitude of the project is more than $10,000,000.

The work is located within various Right-of-Ways (ROWs), including the City of Nogales, the Arizona Department of Transportation, Santa Cruz County, and Union Pacific Railroad, and also located within private property. The Contractor shall be responsible for coordinating the work within the various ROWs and private property, and for obtaining all necessary permits and rights of entry for all work required under this Contract before beginning construction within each respective ROW or private property.

The work is located completely within the United States. The IOI is periodically used for illegal drug trafficking across the border. The Contractor shall fully cooperate with the directions of the staff of the U.S. Customs and Border Patrol (CBP) in the event of a security alert and may be required to stop work for any security reasons in the area. Rehabilitation work under separate contract for Phases 1-3 will be ongoing in adjacent areas; the Contractor shall coordinate with all other onsite contractors.

This project requires work to be conducted in the vicinity of or within the Potrero Creek. The Potrero Creek and its tributaries are listed by the ADEQ as 303[d] Impaired Waters. The Contractor shall comply with the requirements and conditions of the USACE Nationwide Permit (NWP) No. 12, Utility Line Activities and the ADEQ Clean Water Act 401 Water Quality Certification (WQC). Additionally, overflows of the existing sanitary sewer and storm systems in Nogales, Sonora result in increased flows in the Nogales Wash and other waterbodies downstream as well as within the IOI, which may affect the Contractor’s work. These flow increases are unexpected, occur throughout the year, and the duration of the event may be unknown. Since the overflows occur in Mexico, there may be no advance warning to the Contractor. The Contractor shall use its judgment on how to handle the sewage and how to proceed with the work when these overflows occur.

Any work located within the Potrero Creek as well as its tributaries, shall not take place during the monsoon season. Monsoon season typically runs from June 15 to September 30.

The solicitation, plans, and specifications are expected to be posted on or about March 28, 2022 (this is a target date which may slip or change; if the solicitation is not posted on beta.Sam.gov by March 28, 2022, that is because the solicitation is not available for posting).
