Valley Reservoirs-2023 Minor Earth Dams and Pits

DIVISION 2 SECTION MT 02291

SITE WORK MINOR EARTH DAMS AND PITS

Rev. 12-91

Part 1: GENERAL

1.01 WORK INCLUDED:

A. Description: Clearing, grubbing, excavation, and constructing stock water pits at 9 locations and dam embankment repair at 2 locations, with the excavated material being wasted and/or placed in an embankment and/or used for repairs as shown on the drawings and in the Work Data Sheet. Reclaim 9 existing sites by using the embankments to fill and contour the site for drainage and to blend into the natural terrain.

Note: The breach repair at Forest Reservoir is highest priority and will be completed first.

1.02 PROJECT CONDITIONS:

A. Work Limits: Work limits will be staked, and control points established by the Government. Contractor shall not borrow outside staked areas (usually located below reservoir high water lines) without prior written approval from the Contracting Officer.

B. Climatic Conditions: No work required under this section will be allowed when materials are frozen or excessively wet.

C. Haul Distance: The maximum haul distance shall not exceed 1,500 feet, measured by the straight-line distance from the center of mass of the embankment to the farthest point in the borrow area.

PART 2: PRODUCTS

2.01 MATERIALS:

A. Waste Material: Waste material is defined as brush, trees, stumps, frozen lumps, non-plastic silt, and oversized rocks. Oversized rocks are of such size and shape that will interfere with the uniform placement of earth fill materials in layers of specified thickness.

B. Topsoil: Topsoil material is that material which will sustain plant growth and includes sod, roots, and other small vegetative matter which can be uniformly placed to a thickness of 3 inches without protruding from the finished grade.

C. Permeable Material: Sand, gravel, and rock.

D. Common Excavation: Materials to be removed from excavation, except igneous, metamorphic, and sedimentary rock which cannot be excavated without blasting, will be considered common excavation. Common excavation includes rip-able material. Material shall be considered rip-able if the Contractor is able to rip material with a rear-mounted, heavy duty, single-tooth, ripping attachment mounted on a crawler tractor having a power rating of at least 195 net horsepower.

E. Embankment: Embankment materials shall be free of topsoil and waste material. Excavation required for embankment pay quantities shall be subject to the same material requirements as common excavation.

PART 3: EXECUTION.

3.01 PREPARATION:

A. Clearing, Stripping, and Grubbing: The area to be excavated and surface area to be covered by embankments shall be:

1. The Contractor shall clear/grub waste material and conserve available topsoil in stockpiles at designated areas to be replaced on the reclaimed areas and new embankments.

2. Existing water shall be pumped down the drainage areas away from areas to be reclaimed before the filling and grading operations begin.

B. Bank Sloping: Slopes not otherwise designated within the work area, including channel banks, shall be trimmed to a slope not steeper than 3:1.

Suitable material resulting from the bank sloping operation shall be removed and deposited in the embankment, or stockpiled for use in the embankment.

3.02 INSTALLATION:

A. Placement of Topsoil: After construction of the embankment and excavation areas is completed, the stockpiled topsoil shall be uniformly placed to a depth of 3 inches over the downstream slope of embankments which are 3:1 or greater, areas above the high-water line, including the top and upstream slopes of embankments, spillways, borrow pits, and waterfowl islands to form a seedbed for planting.

B. Foundation: After the required preparation has been completed and the core trenches, when required on the Work Data Sheet or drawings, have been excavated, the foundation shall be scarified. Scarifying shall consist of ripping furrows to a depth of 6 to 8 inches. Furrows shall be a maximum of 3 feet apart and parallel to the axis of the embankment.

C. Excavation: Excavated materials shall be removed with a Scraper or Scrapers.

Suitable excavated materials shall be placed directly in required embankments or if authorized, placed in temporary stockpiles, and later placed in the embankment. Excavation material from core trenches for pit reservoirs shall not be stockpiled. Required excavation which is more than the requirements for embankment shall be designated as waste. All waste materials shall be uniformly placed immediately below the downstream toe of the embankment in a manner that will not leave windrows. The Contractor shall use care not to disturb existing vegetation in natural spillways or sod watercourse areas below excavated spillways.

D. Embankment: Embankment and waste/repair materials shall be scraper placed if possible. It is highly recommended that a crawler type dozer also be available for use on these sites to slope any existing breaches to 3:1 slopes or flatter before backfilling. Further requirements are:

1. Materials shall be placed parallel to the axis of the embankment, in even, continuous, approximately horizontal layers not more than 6 inches in thickness(loose). Compaction coverage that ensures that all areas of the fill material have been subjected to at least one pass of the compaction equipment will be considered sufficient. The full cross section of the fill shall be maintained as each successive layer is placed.

2. Successive loads of material shall be placed to produce a distribution of material throughout the embankment that is free from lenses, pockets, streaks, or layers of material differing substantially in texture or gradation from surrounding material.

3. Travel of equipment shall be distributed evenly over the entire width of the embankment to obtain the maximum uniform compaction possible while placing material. Over compaction along the hauling route, which causes lenses to develop, shall be avoided. Should lenses develop, the Contractor shall scarify these areas prior to placing the next lift of materials.

PART 4: MEASUREMENT AND PAYMENT

4.01 METHOD OF MEASUREMENT:

A. General: Unless otherwise provided the slope stake basis of measurement for earthwork will be used. Slope stake measurements taken prior to construction will be used provided the work has been acceptably completed in conformity to the staked lines and slopes. When changes in the original slope stakes are approved, final cross-section or comparable measurements will be taken of the completed work. Clearing, stripping, and grubbing of waste material and stockpiling of topsoil and placing of topsoil, and scarifying foundations will not be measured for payment.

B. Common Excavation: Common excavation material will be measured in the original space occupied and includes:

1. Excavated material from designated borrow areas and cut spillways which is placed directly in water retention pit embankments and retention/detention dam embankments.

2. Excavated materials designated and placed as waste.

3. Excavated material which is suitable for placement in minor retention dam embankment but authorized to be placed in temporary stockpiles.

4. Separate payment for material placed directly in retention/detention dam embankments for repairs will not be made and considered incidental to the Contract.

5. When it is impractical to measure material in the original space occupied due to erratic locations of small deposits, three dimensional measurements of hauling vehicles will be used.

Valley Reservoir-2021 4 Minor Earth Dams and Pits

C. Units: Measurements will be recorded in feet and volumes will be computed in cubic yards.

1. Prismoidal volume (pits) will be computed by the prismoidal formula:

Volume = D(AT + 4AM +AB) 27 (6)

Where: D = Average depth in feet.

AT = Top area in square feet.

AB = Bottom area in square feet.

AM = The area halfway between AT and AB in square feet and is not the average of AT and AB (use end and side slopes to calculate AM).

27 = Conversion factor for cubic feet to cubic yards.

6 = Constant for prismoidal volume (1+4+1).

2. Non-prismoidal volumes will be calculated by the average end area method.

Formula: Volume = L (A1 + A2)

27 (2)

Where: L = Horizontal distance between cross sections.

A = Area of the cross section.

27 = Conversion factor for cubic feet to cubic yards.

2 = Divisor (averages of two areas).

D. Other costs: Costs for mobilization, bonding, or any other associated cost incurred by the Contractor should be uniformly spread in the pay quantities for common excavation items.

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:
