STATEMENT OF WORK

COLORADO RIVER IRRIGATION PROJECT

LINING MAINTENANCE

LINING REPAIR

I. PURPOSE

The Bureau of Indian Affairs (BIA), Colorado River Agency, Colorado River Irrigation Project (CRIP) is seeking to establish a contract for the maintenance of the approximately 140 miles of existing canal lining, to repair or replace broken or missing segments of the concrete lining.

II. PROJECT BACKGROUND

General:

The Colorado River Indian Reservation was established by the Act of March 3, 1865. It is home to the Mohave, Chemehuevi, Hopi, and Navajo Tribes. Encompassing approximately 463 square miles, the Reservation is in the western part of La Paz County, Arizona, along 48 miles of the Colorado River and includes portions of San Bernardino and Riverside Counties in California.

The (CRIP) provides water for agricultural uses on the Colorado River Indian Reservation (CRIR). Irrigation started in 1867 when funds were provided to construct a canal for irrigating the CRIR. The water for the Project comes from the Colorado River through the Main Canal Headworks located at Headgate Rock Dam. The CRIT holds approximately 24% of Arizona’s water rights to the Colorado River. With an assessed acreage of 79,529 acres, primary crops are alfalfa, cotton, and wheat. The estimated annual crop value is $117.7 to $143.9 Million (2013).

III. SCOPE OF WORK

The CRIP diverts irrigation water year-round except for the dry-up periods. The Lateral 90 dry-up is one week in early December, the Main Canal dry-up is two weeks in mid-January and Lateral 73 in one week in mid-February. The majority of lining repair work is done during the dry-up periods. This contract will be for a full year so that the vendor can respond to any unplanned lining repair emergency.

The Vendor shall perform all duties and furnish all personnel, materials, equipment, and facilities necessary to deliver to the BIA the deliverables described in this document. The process for repairing existing lining include the identification of the damaged concrete site, removal of the damaged concrete, preparation of the canal bank for the placement of the new Dry Processed Gunite Material (Gunite) and area clean-up. There may be as many as 30 locations per day.

1. The CRIP will identify the location of the damaged concrete lining. CRIP will mark the site beginning as soon as the water in the canal has been drained. The vendor shall locate the identified concrete repair sites to plan their work.

2. The CRIP will remove the damaged concrete lining using equipment with the proper reach and capability. The vendor will have at least one employee on site with CRIP equipment to assist in removing any smaller waste material and to assist the equipment operator to place soil to canal bank as necessary.

3. The vendor will prepare the earthwork of the exposed canal bank for the placement of new Gunite. Preparation of the earthwork includes compaction of the soil as needed, grading to a constant 4” thick from earth to even with the existing lining surface.

Preparation also includes placement of 4” X 4” wire grid held 1” from soil surface to reinforce the new Gunite. The canal bank is on a 1.5:1 side slope so the vendor must be able to maintain the safety of the employees from sliding or falling the six to 25 feet of bank depending on the location of the repair. During the annual dry-up there may be water left in the canal that may require small coffer dams to be made to isolate the lining damage near the bottom of the canal so the bank preparation can be completed. The vendor is responsible for the placement and removal of these coffer dams. With proper cooperation between the vendor and the CRIP these coffer dams can be placed with the CRIP equipment with minimal travel time for the track type equipment.

4. The CRIP will purchase the Gunite and have it delivered to the vendor on the canal bank at each site. The CRIP will purchase the 4’X4” wire and have it available at the CRIP Poston Yard for the vendor to transport to the Gunite repair site.

5. The vendor shall place the Gunite onto the prepared site. The canal bank is on a 1.5:1 side slope so the vendor must be able to maintain the safety of the employees from sliding or falling the six to 25 feet of bank depending on the location of the repair. The top edge of the lining shall be level and consistent with the existing lining. The new Gunite will be placed to the same outer edge as the existing concrete. The surface of the placed Gunite will be finished with a bull float or other screed type tool for a smooth constant grade matching the existing concrete. Any extra or spoiled Gunite that was placed but screed from the repair must be removed from the canal. With cooperation from the vendor the CRIP may assist the vendor with waste Gunite material removal from the canal. The vendor shall clean up the work area at each site.

6. The CRIP and the vendor shall meet each morning during the dry-up period or every day the vendor is on the CRIP right of way, to discuss the work plan and any deficiencies that may arise during the contract period and prepare plans to overcome those deficiencies.

7. The contract will be in force for 12 months and requires the vendor to be on call to make any emergency repairs that may occur on the CRIP. The vendor shall agree to move equipment and personnel to the CRIP within 48 hours of notification by CRIP.

8. Payments are made via FBMS IPP weekly upon submission of invoice.

IV BIDDING REQUIREMENTS

It is difficult to know where the lining repairs are going to be or the total area of the new Gunite placement while there is water in the system. The CRIP requires that the Pricing of the lining repair work be calculated as a per day requirement including all costs. By defining the cost per 10-hour day the CRIP can control the cost of the work without determining the square footage of each lining repair that is unknown prior to dewatering the canal. For bidding purposes, the CRIP plans to have 19 days of dry-up available days before the water must be returned for irrigation.

There may be additional days of work during non-dry-up periods for laterals that can be dried up during the year. These additional days will also be subject to the daily price. Only cost per day bids will be accepted. Only the placement of Gunite materials will be accepted for bidding purposes.

(d) The presence or absence of a Government inspector does not relieve the Contractor from any contract requirement, nor is the inspector authorized to change any term or condition of the specification without the Contracting Officer’s written authorization. (e) The Contractor shall promptly furnish, at no increase in contract price, all facilities, labor, and material reasonably needed for performing such safe and convenient inspections and tests as may be required by the Contracting Officer. The Government may charge to the Contractor any additional cost of inspection or test when work is not ready at the time specified by the Contractor for inspection or test, or when prior rejection makes reinspection or retest necessary. The Government shall perform all inspections and tests in a manner that will not unnecessarily delay the work. Special, full size, and performance tests shall be performed as described in the contract.

(f) The Contractor shall, without charge, replace or correct work found by the Government not to conform to contract requirements, unless in the public interest the Government consents to accept the work with an appropriate adjustment in contract price.

(h) If, before acceptance of the entire work, the Government decides to examine already completed work by removing it or tearing it out, the Contractor, on request, shall promptly furnish all necessary facilities, labor, and material. If the work is found to be defective or nonconforming in any material respect due to the fault of the Contractor or its subcontractors, the Contractor shall defray the expenses of the examination and of satisfactory reconstruction. However, if the work is found to meet contract requirements, the Contracting Officer shall make an equitable adjustment for the additional services involved in the examination and reconstruction, including, if completion of the work was thereby delayed, an extension of time. (i) Unless otherwise specified in the contract, the Government shall accept, as promptly as practicable after completion and inspection, all work required by the contract or that portion of the work the Contracting Officer determines can be accepted separately.
