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 earthfill materials in layers of specified thickness.

B. Topsoil: Topsoil material shall be considered to be that material which will sustain plant growth and includes sod, roots, and other small vegetative matter which con 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. 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, Grubbing: The area to be excavated and the surface area to be covered by embankments shall be:

1. Cleared of waste material. The Contractor shall conserve available topsoil.

2. Stripped of topsoil, with the topsoil deposited in stockpiles at designated locations.

DIVISION 2 SECTION MT-02291

Rev. 12-91

MT-02291 - 3

3. Grubbed to remove remaining waste material.

B Bank Sloping: Slopes not otherwise designated within the foundation 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.

C Utilities: Before starting excavation, establish the location and extent of overhead and underground utilities in the work area. Protect active utility services uncovered by excavation. Damage to any utilities shall be repaired or replace at the Contractor’s expense. Repair to damaged utilities shall be started immediately unless otherwise authorized by the State of Montana. (Montana Utility Mark Out Telephone No. 1-800-424-5555)

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 highwater 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 Summary Chart 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: 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 in excess of the requirements for embankment shall be designated as waste. 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:

1. Materials shall be placed parallel to the axis of the embankment in even, continuous, approximately horizontal layers not more than 8 inches in thickness. 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

MT-02291 - 4

substantially in texture or gradation form 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 material.

4. Permeable materials shall be placed downstream of the embankment core trench in the embankment to act as a underdrain or shall be placed above the high-water line of the embankment.

3.03 FIELD QUALITY CONTROL:

A. Uncompacted Embankment: Routing equipment as described above will be sufficient compaction. The Contractor will not be required to perform additional passes of his hauling equipment to increase the degree of compaction.

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 topsoil, stockpiling and placing 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, water retention pits, pit cut spillways, and pit core trenches which is placed directly in water retention pit embankments and retention 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. Stockpiled material which is subsequently placed in an

MT-02291 - 5

embankment will also be included for payment under the respective pay item for embankment.

4. Separate payment for material excavated and placed directly in minor retention dam embankment or embankments from borrow areas, cut spillways, and core trenches will not be made under common excavation but will be considered for payment as embankment only.

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.

C. Embankment: Embankment material which includes the space occupied by the embankment and dam core trench will be measured in-place for minor retention dams. Embankment shall be classified as compacted or uncompacted as designated on the Work Summary Chart. The existing reservoir shall have their top and front slopes reconstructed.

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

1. Nonprismoidal 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).

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:

Pay Item Pay Unit MT-02291(1) Common Excavation ...........................Cubic Yard
