PART 2 PRODUCTS (Not Applicable)

PART 3 EXECUTION

3.1 HAUL ROADS

Haul roads between borrow areas and fill areas shall meet the minimum requirements specified herein. At no additional cost to the Government, the Contractor shall increase the minimum specified requirements as necessary, due to job site conditions, to assure safe operations. Whenever practical, one-way haul roads shall be used. Haul roads used for this work shall comply with the following:

(a) One-way haul roads for off-the-road haulage equipment; (e.g., belly dumps, scrapers, and off-the-road trucks) shall have a minimum usable width of 25 feet. One-way haul roads for over-the-road haulage equipment (e.g., dump trucks, etc.) shall have a minimum usable width of 15 feet.

When it is impractical to obtain the specified minimum widths for one-way haul roads (e.g., a road on top of a levee), a usable width of not less than 10 feet may be approved, provided a positive means of traffic control is implemented. Such positive means shall include signs, signals, or signalmen and an effective means of speed control.

(b) Two-way haul roads for off-the-road haulage equipment shall have a minimum usable width of 60 feet. Two-way haul roads for over-the-road haulage equipment shall have a minimum usable width of 30 feet.

(c) Haul roads shall be maintained to keep the surface free from potholes, ruts and similar conditions that could result in unsafe conditions. Haul roads shall be maintained free of all construction related debris, including loose riprap.

(d) Curves and changes in grade shall allow a minimum sight distance of 200 feet for one-way haul roads and 300 feet for two-way haul roads. Sight distance is defined as the centerline distance an equipment operator (4.5 feet above the road surface) can see an object

SECTION 31 23 00.00 09 Page 2

4.5 feet above the road surface. When conditions make it impractical to obtain the required minimum sight distances (e.g., ramps over levees), a positive means of traffic control shall be implemented.

(e) Dust abatement shall permit observation of objects on the roadway at a minimum distance of 300 feet.

(f) Haul roads shall have the edges of the usable portion marked with posts at intervals not greater than 50 feet on curves and not greater than 200 feet elsewhere. Such markers shall extend 6 feet above the road surface, and for nighttime haulage shall be provided with reflectors in both directions.

(g) Haul roads shall not block or impede drainage in or through the right-of-way. The Contractor is responsible for any damages resulting from haul roads blocking or impeding drainage. (See the Contract Clause PERMITS AND RESPONSIBILITIES.)

(h) The contractor shall not use the crown of the levee as a haul road.

3.2 EXCAVATION IN BORROW AREAS

3.2.1 General

The rights-of-way and earth materials for constructing the work will be furnished without cost to the Contractor, at locations specified herein and shown on the drawings. Notwithstanding any other provision of this contract, the Contractor is required to obtain all borrow material from the Government furnished borrow areas, ditches and other required excavations.

Contractor furnished borrow areas will not be permitted.

3.2.1.1 Equipment

The Contractor shall provide the types of equipment as necessary to perform the required excavation according to the in situ conditions of the borrow area.

3.2.2 Borrow Areas

3.2.2.1 Requirements

Borrow areas shall conform to requirements prescribed herein and as shown on the drawings. The material necessary for the construction of the embankments shall be procured from borrow areas and required excavations by haulage or otherwise. The permissible excavation depths in the borrow areas are indicated on the drawings, but the right is reserved, in accordance with the Contract Clause CHANGES, to modify the permissible depths in accordance with subsurface conditions determined as the work proceeds. Excavation to the permissible depths may require excavation below the ground water table. The bottom of the borrow areas excavated under this contract shall be dressed to the extent necessary to provide a reasonably smooth surface that can readily be traversed by a 50 to 60-horsepower farm tractor pulling a rotary-type pasture mower and sloped to provide surface drainage to the low side of the borrow area as soon as all usable materials have been removed or the Contractor has completed the use of the borrow area. Abrupt changes in grade shall be avoided.

Unsuitable material wasted in the borrow areas shall be placed to lines and grades shown on the drawings and sloped to drain. Any excavation below the depths and slopes specified herein or shown on the drawings shall be

SECTION 31 23 00.00 09 Page 3 backfilled by the Contractor, at no cost to the Government, to the specified permissible excavation line, with suitable material placed and compacted in accordance with Section 31 24 00.00 09 EMBANKMENT, paragraph SEMICOMPACTED EMBANKMENT. The borrow areas excavated under this contract shall be drained of water regardless of its source, including subsurface water, and kept free of water during excavation, as excavation will not be permitted in water nor shall excavated material be scraped, dragged or otherwise moved through water. Drainage of borrow areas shall be accomplished by ditching, sump pumping or other approved methods. The borrow areas excavated under this contract and inundated from high river stages shall be drained and allowed to dry to a workable condition as quickly as practicable after the high river stage has passed. No additional payment will be made for keeping the borrow areas drained and free of water during excavation. Rights-of-way for drainage will be furnished by the Government at the locations shown on the drawings. The Contractor, at his option, may use rights-of-way for drainage other than those furnished by the Government provided that no additional clearing is required and their location and dimensions are approved by the Contracting Officer, and provided that the Contractor has obtained the rights-of-way in accordance with Section 01 00 00.00 09 GENERAL CONTRACT REQUIREMENTS, paragraph RIGHTS-OF-WAY. Except as required by variable right-of-way widths, abrupt changes in borrow area alignment shall be avoided. To conserve arable land and make optimum use of available borrow, the excavation of the borrow areas, shall be made continuous throughout the length of the borrow areas to the permissible borrow depths, and at the width necessary to provide the required quantity of suitable material, and in such manner that all suitable available material within the required width between the leveeward limits of the borrow areas and the back of the borrow areas will be utilized. The Contractor shall submit an excavation plan for approval by the Contracting Officer and shall not begin excavation until the Contracting Officer's approval has been received. The plan shall contain, as a minimum, the following:

a. The Contractor's proposals for implementing Section 01 57 20.00 09 ENVIRONMENTAL PROTECTION insofar as that section applies to borrow areas.

b. The Contractor's proposed methods for draining and keeping the borrow areas free of water during excavation under this contract.

c. The Contractor's proposed methods for draining borrow areas excavated under this contract which may be inundated by high river stages.

d. The Contractor's proposals for conserving arable land and for making optimum use of available borrow, including the Contractor's proposed methods for smoothing the bottom of the borrow areas after having completed use of the borrow areas.

3.3 DISPOSITION OF MATERIALS

3.3.1 Suitable Materials

Excavated materials which are suitable for incorporation in the levee embankment and berm embankment, or other required fill or backfill, shall either be placed directly therein, or stockpiled and subsequently used in the levee embankment, and berm embankment, or other required fill or backfill.

SECTION 31 23 00.00 09 Page 4

3.3.2 Unsuitable Materials

Materials from required excavation which, as defined in Section 31 24 00.00 09 EMBANKMENT, paragraph UNSUITABLE MATERIALS, are unsuitable for levee embankment, or other required fill or backfill material will be ordered wasted and shall be disposed of in abandoned portions of borrow areas. This unsuitable material shall be shaped so that its surface is free from abrupt changes in grade and shall be sloped to drain. Where possible, unsuitable materials in borrow areas shall not be removed.

3.3.3 Temporary Stockpiles

No material shall be stockpiled on the existing levee or berm. Temporary stockpile areas shall be approved by the Contracting Officer before being used.

3.4 EXCAVATION IN OTHER AREAS

3.4.1 General

Excavation from other areas shall consist of removal of material in preparing the levee embankment and berm embankment foundations to the lines and grades shown on the drawings, removal of materials from ditches and removal of unsuitable materials as defined in Section 31 24 00.00 09 EMBANKMENT, paragraph UNSUITABLE MATERIALS. Whenever unsuitable foundation material is encountered, the unsuitable material shall be removed to the depth directed by the Contracting Officer. Care shall be exercised by the Contractor in excavating to the lines and grades shown and in removing unsuitable materials so as not to excavate below the grades specified or depth directed. Excavation below the lines and grades specified or the depth directed shall be backfilled by the Contractor at no cost to the Government. Such backfill shall be brought to grade with suitable material with each layer placed and compacted as specified in Section 31 24 00.00 09 EMBANKMENT, paragraph SEMICOMPACTED EMBANKMENT. Excavated materials shall be disposed of as specified in paragraph DISPOSITION OF MATERIALS.

3.4.2 Excavation

Drainage ditches shall be excavated to the cross sections, lines, and grades shown on the drawings. Suitable material excavated from these ditches shall be used in the embankment(s). Any excess material or material unsuitable for use in the embankment and berm embankment shall be wasted and shall be placed along the ditch banks but not nearer to the ditch bank than 3 feet, or at other locations shown on the drawings.Any excess material or material unsuitable for use in the berm embankment shall be disposed of as described in paragraph UNSUITABLE MATERIALS. The right is reserved to require such other ditching as is deemed desirable and which can be performed without unreasonable difficulty by the equipment on the job. Suitable material excavated from such ditching may, at the option of the Contractor, be used in the embankment. Material not so used shall be wasted and shall be placed along the ditch banks as stated above.

3.4.3 Acceptance

Prior to the acceptance of the work, the Contractor shall excavate sediments from ditches as necessary to restore them to grade and section.

Disposal of such material shall be as directed by the Contracting Officer.

No separate payment will be made for this work.

SECTION 31 23 00.00 09 Page 5

3.5 TRAVERSES

All traverses within the riverside construction borrow areas shall be traverses removed and all costs shall be included in the contract unit price for "Berm Embankment, Uncompacted" as applicable.

At Sta. 4902+00 and 4935+00, the traverse from the levee to the riverside construction borrow shall be removed to the natural ground surface.

Payment for these three two traverses will be made in the contract job price for "Traverses."
