Statement of Work (SOW)

REPAIR SANITARY SEWER DEFICIENCIES, PH III

Project Number: CZQZ14-0554

Cannon Air Force Base, New Mexico

2 4 June 2015

1. OBJECTIVES: The objectives of this Work include but are not limited to:

1.1. The scope of work will include rehabilitation of the existing sanitary sewer system in sub-basin 1 at Cannon Air Force Base, New Mexico. A total of 52 sanitary sewer manholes will be rehabilitated. The work will include everything from a simple cleaning to coating the existing manhole with high build epoxy liner.

1.2. The project is prepared to provide enhanced performance of the existing sanitary sewer system and to limit the amount of storm water inflow and infiltration (I/I). Thirty-one manholes will receive new water-tight frames and covers and be adjusted vertically to eliminate the amount of surface water intrusion.

1.3. Thirty-three manholes that will be rehabilitated will receive a concrete collar which is designed to not only protect the frame and cover from abuse and off-set forces, but to further restrict surface water influences.

1.4. Project work includes Close Circuit Televising (CCTV) inspection of 1,130 LF of sewer pipe.

Contractor to submit video files along with an analysis report. The report shall include the pipe size of all piping, damage location, and condition assessment of each damaged portion of sewer pipe. Repair actions shall be negotiated after report is submitted.

1.5. There are 4 sanitary cleanouts that will also be repaired as part of this project. The work here will include cleaning and replacement of the surface caps and concrete collars for protection.

1.6. The complete requirements for this project shall be completed as shown on sheets 00G001 and 00C101.

2. BACKGROUND: The sanitary sewer collection system as Cannon AFB, NM consists of approximately 23.67 miles of gravity mains and 409 manholes. The collection system is divided into seven (7) sub-basins. Of the seven sub-basins; the focus of this project will be in sub-basin 1.

In 2007, the Air Force commissioned URS Group (URS) to conduct a comprehensive Sanitary Sewer Infiltration and Inflow Evaluation and Rehabilitation Study. As a result URS developed solutions to correct Inflow and Infiltration (I/I) problems identified during manhole inspections, smoke testing and flow monitoring. This project again will focus on sub-basin 1 of the URS report.

The objective of the project is to evaluation the condition of the existing sanitary sewer system (i.e.

sub-basin 1), based on a site visit, consultations with building users and Air Force representatives, and referenced reports and documents, in order to determine appropriate design solutions and to document all solutions for Air Force review and approval and subsequent competitive bidding purposes.

Therefore, the basis of design is the SANITARY SEWER INFILTRATION AND INFLOW EVALUATION AND REHABILITATION PLAN, URS, June 2009. The will be referred to as ‘the plan’.
