• Reseed all rebuilt, disturbed, and reclaimed areas with perennial seed mix.

Paleface Reservoir:

• If necessary, dewater reservoir and construction area.

• Remove rip rap from existing spillway and stockpile.

• Remove and dispose of culvert at existing spillway. Fill and compact back to original grade.

• Knock down sides of head cut at existing spillway. Backfill to match downstream slope of existing dam embankment.

• Excavate new spillway to the left side of the existing dam embankment. Location noted

12/18/2024 01010-2 on contract drawings.

• Use excavation from new spillway to build new dike to plug old spillway, raise crest elevation of dam embankment, and build up upstream face of dam embankment. Dam face and dike embankments shall be built to 3:1 slope.

• Grade both banks of new spillway to a 3:1 slope to a smooth surface for the entire length, tapering back to existing natural grade.

• Prepare spillway channel and embankments for permanent erosion control installation by placing topsoil, top with 1 inch of compost, and incorporate perennial seed mix.

• Reseed new spillway, new dike, and all rebuilt, disturbed, and reclaimed areas with perennial seed mix.

Whiteface Reservoir:

• If necessary, dewater reservoir and construction area.

• Excavate and contour area in front of inlet of existing culvert to direct water flow toward inlet.

• Raise the crest elevation across the upstream edge of the existing secondary spillway inlet with a dike to regulate flow into the spillway. Align this spillway crest along the access road. See detail 3/12 of contract drawings.

• Knock down and excavate sides of head cuts at primary spillway.

• Fill and shape area around existing culvert inflow and fortify with hand-laid riprap headwall.

(Flexamat Plus).

• Knock down and reshape the area of head cuts at the secondary spillway. Make a gradual sloping grade from edge of natural grade to base of head cut.

• Prepare secondary spillway surface and embankments for permanent erosion control installation by placing topsoil, top with 1 inch of compost, and incorporate perennial seed mix.

• Install permanent erosion control (Flexamat Plus) along this new gradual sloping grade.

Note: It is important to provide a smooth transition at the upstream end of the permanent

12/18/2024 01010-3 erosion control (Flexamat Plus) to ensure the direction of water flow into the spillway.

• Install riprap at the downstream end of permanent erosion control (Flexamat Plus).

2022 Phillips Reservoirs Repair QUALITY CONTROL/ QUALITY ASSURANCE 11/06/2023 01400-1

DIVISION 1 - GENERAL SECTION 01400 - QUALITY CONTROL/

REQUIREMENTS QUALITY ASSURANCE

1.01 DEFINITIONS:

A. Quality Control - planned and specific actions or operations necessary to produce a product that complies with the contract documents. Quality control consists of actions, inspections, sampling, and testing necessary to ensure the work follows the contract documents and to control production and construction processes. Quality control is keyed to the construction sequence to quickly determine when the work is out of compliance with the contract documents and to respond to correct the situation and bring the work into compliance. Quality control is the responsibility of the CONTRACTOR.

B. Quality Assurance – planned and systematic observations, testing, and actions to verify that the work complies with the contract documents. Quality assurance includes oversight of the CONTRACTOR’s quality control, verifying the results of the CONTRACTOR’s testing and additional assurance sampling and testing. The GOVERMENT will provide quality assurance at a level determined necessary by the Contracting Officer.

C. Verification/Compliance Testing – sampling and testing which is carried out independent of the CONTRACTOR’s quality control testing to confirm/verify that the work complies with the contract documents. The frequency of verification/compliance testing will be determined by the Contracting Officer. Verification/compliance testing will not be used to determine construction procedures or operations (i.e., rolling patterns, lift thickness, etc.). Verification/compliance testing will be provided by the Contracting Officer.

PART 2 - PRODUCTS - NONE

PART 3 - EXECUTION

3.01 COOPERATION WITH QUALITY ASSURANCE:

A. Assure that the GOVERNMENT and Contracting Officer always have access to all work areas while work is in progress.

B. Notify the Contracting Officer when the work is ready for quality assurance/quality control testing. Establish and update the construction schedule to provide the Contracting Officer estimated sampling/testing dates and times. Contracting Officer may choose to obtain a split and comparison test of any samples collected for quality control testing. Provide adequate notice of testing plans to coordinate collection of samples.

*Diameter of the median dimension when measuring length, depth, and breadth.

** Include rock spalls or cobbles in an amount to just fill spaces between larger rocks, but not in excess. Larger-sized rock should be in point-to-point contact. Minimum rock size of 4 inches.

3.01 AREAS TO RECEIVE EROSION PROTECTION

1. Place riprap erosion protection to the lines and grades as shown on the Contract Drawings. Do not place riprap until surface has been prepared, and approved by the

CO.

3.02 PLACING

A. Subgrade Preparation:

1. Excavate, fill, or grade foundation soils in accordance with Section 02300 so riprap limits are as indicated on the Contract Drawings or as directed by the CO.

2. Install non-woven geotextile fabric underlayment on prepared surfaces. Ensure required manufacturer’s Recommendations for overlaps are maintained and outer edges of geotextile are buried a minimum of 1 foot below grade. Geotextile fabric specifications are outlined in section 02370, Geosynthetics.

12/18/2024 02275-4

B. Slope-protection rock need not be hand-placed (except at culvert inlets) or compacted but shall be handled and dumped to avoid material segregation. Riprap should be placed with an average depth as specified on the Contract Drawings. Riprap should be placed consistently and evenly throughout the marked areas.

C. Hand place 12-inch riprap at culvert inlet protection for Taint and Whiteface Reservoirs. This involves laying of rocks in an interlocking pattern with the voids between the larger rocks filled with smaller rocks. The finished surface shall be kept relatively even to decrease flow turbulence at the culvert inlet.

D. Place Class II riprap so that larger rocks are evenly distributed, and smaller rocks filling the spaces.

E. Place Class III riprap at floor and slopes of stilling basins at Taint and Whiteface Reservoirs.

Place riprap so that larger rocks are evenly distributed, with smaller rocks filling the spaces. Place rocks in such a way as to maximize dissipation of energy of water flow by creating rough and irregular surfaces at the basin.

F. Dump and smooth by moving rocks into position so that material, when in place, is stable.

G. Begin slope-protection at toe and proceed up the slope.

H. Leave no unfilled spaces within slope protection.

4.01 METHOD OF MEASUREMENT:

A. Units: Riprap supply and installation will be measured in cubic yard of rock installed and will be measured using neat lines. Riprap supply and installation will include transportation from offsite source locations. Supply and install geotextile fabric and place riprap as per specifications and Contract Drawings.

4.02 BASIS OF PAYMENT:

A. Payment: Prices and payment will be full compensation for the work described in this section. Payment will be made under:
