Performance Work Statement Spawning Gravel Replenishment Project – Stanislaus River

Dated: February 5, 2015

Part A – General Information:

1. Introduction: The U.S. Bureau of Reclamation (USBR) in cooperation with the California Department of Fish and Wildlife (CDFW) is conducting Chinook salmon and steelhead trout spawning and rearing habitat restoration activities on the Stanislaus River downstream of Goodwin Dam. USBR is acquiring of 5,000 to 8,000 tons of suitable gravel for the project. The information in Part B – Work to be performed specifies the requirements.

2. Point of Contacts: Technical Representative: Mr. John Hannon Fisheries Biologist 916-414- 2413, jhannon@usbr.gov;

Part B – Work to be Performed:

1. General: The Contractor shall furnish and deliver 5,000 tons of suitable spawning gravel to the designated sites as specified.

2. Materials: Obtain gravel from sources or deposits within the Stanislaus River basin.

a. Alternative Sources may be used upon acceptance by the Contracting Officer.

b. If mine tailings are used, they are to be obtained from a site not continuously saturated with water.

The gravel shall consist of hard, dense, and durable particles of river run, well rounded materials. The materials shall meet the gradation limits specified below and be washed to be free from fines. Crushed or angular pieces are not acceptable.

3. Spawning Gravel Gradation: Reasonably well-graded mix made using a ¼” screen on the bottom to approximate the limits shown in Table 1 - Mix Gradation. The D50 (median diameter of sample) of the mix should be approximately one inch. Refer to ASTM D 6913-04 (2009) Standard Test Methods for Particle-Size Distribution (Gradation) of Soils Using Sieve Analysis.

Table 1 - Mix Gradation Particle Size (inches) Percent Passing Percent Retained

4” 95-100 0-5 2” 75-85 15-25 1” 40-50 50-60 ¾” 25-35 65-75 ½” 10-20 80-90 ¼” 0-5 95-100

4. Gravel shall be washed and have a Cleanness Value of 85 or higher based on CalTrans Test #227 (http://www.dot.ca.gov/hq/esc/ctms/pdf/CT_227.pdf).

5. Quality Assurance: Prior to delivery of spawning gravel, the Contracting Officer’s Representative (COR) will visit the gravel source to inspect the gravel.

a. The Contractor shall provide the COR laboratory tests upon request (gradation and cleanness) confirming that the processed material meets these requirements.

b. Provide 72 hours advance notice of the need for the following two required inspections. First inspection will be near the beginning of the production of the mix or after the first approximately 1,000 tons has been processed. Purpose of early inspection is to confirm compliance with quality of material specifications and remedy any concerns prior to delivery. Second inspection will be at a time to be determined at around 3,000 tons processing completed. Inspection will consist of a visual examination of representative samples of the processed materials at the processing location. Results of gradation tests of the mix shall be provided at the time of inspection or prior to delivery of material to the site. Tests of cleanness shall be provided if requested by the Government.

c. The Government reserves the right to obtain samples of representative materials at the source for confirmation testing at any time during the gravel processing.

d. The Contracting Officer or the COR has the right to reject any load of spawning gravel delivered to the project site that does not appear to meet specification for gradation or cleanness. Any dispute on the acceptability of the spawning gravel shall be resolved by the testing of the spawning gravel in question. The Contractor shall provide the necessary testing and labor to see that the test is performed at no additional cost to the Government. The Contractor shall account for any associated costs or delays in the prices offered for the work.

6. Schedule:

a. The Contractor shall deliver the spawning gravel materials beginning August 3, 2015, between the hours of 7 a.m. and 4:30 p.m., Monday through Friday. Delivery of gravel materials shall be completed by August 21, 2015. The Contractor shall not work on designated Federal holidays. Gravel deliveries shall be coordinated with CDFW who will place the gravel in the river under a separate agreement (point of contact to be provided after award). The delivery schedule may be adjusted to comply with permit requirements or due to streamflows that allow work in the river.

b. The stockpile areas noted in Figure 1 have limited capacity. CDFW will move the 5,000 tons of gravel from the stockpiles into the river concurrent with deliveries. The Contractor shall deliver between 500 and 800 tons of gravel per day.

c. The Contractor shall advise the Government of its proposed working hours and site delivery schedules

48 hours prior to starting deliveries, and 24 hours prior to any changes to the proposed delivery schedule.

7. Stockpile Preparation and Management:

a. Prior to commencement of deliveries, the Contractor shall visit the site with the COR to confirm stockpiling locations and stockpile area preparation.

b. The Contractor shall provide all the necessary equipment, labor, and materials to load and transport the gravel to the site. All site preparation for the stockpile area and all stockpile management of the material will be performed by CDFW.

c. CDFW will be responsible for providing all necessary equipment, labor, and material to move and place the 5,000 tons of stockpiled gravel material into the river under separate agreement with Reclamation.

8. Site Location/Access:

a. Access to the site is through a locked gate located off Tulloch Road approximately ¼ mile downstream of Goodwin Dam (See Figures 1 and 2). CDFW crews will ensure that the gate is open as needed for deliveries by the Contractor.

b. Only transfer trucks shall be used to deliver gravel materials. There is insufficient space for end dumps.

c. The existing bridge over the OID canal has a limited load carrying capacity. To prevent overloading the bridge the Contractor shall comply with the following:

i. The amount of gravel carried across the bridge in any single load shall not exceed 12 tons.

ii. An abrupt, vertical drop of several inches in the road surface exists on the uphill approach to the bridge. Loaded trucks shall approach the uphill abutment very slowly and ease the front and rear wheels gently down this drop to avoid causing impact loading on the bridge.

iii. Loaded trucks shall cross the bridge at low speed to avoid causing impact loading on the bridge.

iv. Loaded trucks shall use means to insure that the truck travels down the centerline of the bridge.

This will keep the wheels over or near main beams. The truck shall not begin its turn until it is completely off the bridge so as to keep the wheel loads well away from the mid-span of the planks.

9. Measurement & Payment:

a. A total of 5,000 tons shall be delivered under this Statement of Work. All gravel materials will be measured for payment by the number of tons (2,000 pounds) of material placed within the required stockpile locations. Tonnage will be based on weight tickets from scales certified by the State of California.

b. Payment: Payment for furnishing and delivering gravel materials will be made at the unit price per ton, which unit price shall include all costs for furnishing or procuring, loading, and transporting the gravel materials.

11. Landscape Preservation: The Contractor shall exercise care to preserve the natural landscape and conduct the operations so as to prevent any unnecessary destruction, scarring, or defacing of the surroundings in the vicinity of the work.

12. Traffic Control: The Contractor shall meet requirements of USBR RSHS, Section 9 and 20, and MUTCD, Part 6.

Provide cones, delineators, concrete safety barriers, barricades, flasher lights, danger signals, signs, or other temporary traffic control devices required to protect work and public safety. Remove traffic control devices when no longer needed. Provide flaggers and guards as required to prevent accidents and damage or injury to passing traffic.

13. Performance Based Plan:

a. Monitoring Performance: During the course of the evaluation period, the COR will track Contractor performance. Interim (mid-term) evaluations may be provided to identify strengths and weaknesses in the Contractor's performance during the period being evaluated. At the end of the period, the COR will assess the Contractor's performance in accordance with the Quality Assurance Surveillance Plan (QASP) and report to the Contracting Officer.

b. Contractor Self-Assessment: Following each evaluation period, the Contractor may provide a written self-assessment of its performance to the COR to be considered in its report to the Contracting Officer. The self-assessment shall be submitted not later than 5 working days after the end of each evaluation period. The self-evaluation shall not exceed 1 page per PRS element. The self-assessment shall address both the strengths and weaknesses of the Contractor's performance during the evaluation period. Where deficiencies in performance are noted, the Contractor shall describe the actions planned or taken to correct such deficiencies and avoid their recurrence. The self-assessment itself will NOT be the basis for the payment determination.

c. COR Recommendation: The COR will consider all evaluations and any other pertinent information, including Contractor self-assessment, and will prepare a report to the Contracting Officer with findings and recommendations. The Contractor will be provided a copy of the draft findings and recommendations of the COR and will be afforded the opportunity to identify factual errors. The COR's draft recommendation is not subject to negotiation and the COR will not engage in discussions with the Contractor. Any errors identified by the Contractor will be addressed by the COR in its final report. The Contractor will be provided a copy of the final COR report at the same time the report is submitted to the Contracting Officer.

d. Payment Determination: The Contracting Officer may meet with the COR to discuss the COR's report. The Contracting Officer will make a final determination in writing as to the percentage of work successfully completed, and the resulting payment to be made. A copy of the determination will be provided to the Contractor no later than 45 calendar days after the end of the period being evaluated. All Contracting Officer decisions regarding payment calculations are unilateral decisions made solely at the discretion of the Government.

e. Payment Re-Calculations: Notwithstanding any other clause of this contract, payment re-calculations will be made within the later of 60 days after the end of the evaluation period or 30 days after receipt of an approved invoice.

f. The Quality Assurance Surveillance Plan is one evaluation method the government uses to perform surveillance to determine whether the Contractor meets the standards of performance as defined in the PWS. The absence of a QASP for any contract requirement, however, shall not detract from its enforceability or limit the rights or remedies of the government under any other provision of the contract in determining the quality of the Contractor performance.
