EMBANKMENT.

1.2 MEASUREMENT AND PAYMENT

1.2.1 Structural Excavation and Backfill

No separate measurement will be made for structural excavation. Payment for structural excavation will be made at the applicable lump sum price for "Structural Excavation", unless otherwise specified to be included in the contract prices for items of work to which the work is incidental thereto.

Price and payment shall constitute full compensation for furnishing all plant, labor, materials, and equipment to complete the work as specified herein and as shown on the drawings. Backfill will be measured and payment will be made as specified in Section 31 24 00.00 12 EMBANKMENT.

1.4 QUALITY CONTROL

The Contractor shall establish and maintain quality control for excavation operations to assure compliance with contract requirements and maintain records of his quality control for all construction operations including but not limited to the following:

(1) Equipment. Type, size, and suitability for construction of the prescribed work.

(2) Structural Excavation. Check grade, slopes, and dimensions for compliance with design sections.

(3) Grade Tolerances. Check fills to determine if placement conforms to prescribed grade and design section.

(4) Construction. Layout, maintaining existing drainage, moisture control, thickness of layers, spreading and compacting.

(5) Classification of soils, placing and compacting of structural fill, and density tests.

(6) Control Testing. The Contractor shall perform all control testing such as particle size analysis. No separate measurement and payment will be made for control testing required in this paragraph.

2.2 EQUIPMENT

Equipment for compaction shall conform to the requirements herein and the applicable requirements of Section 31 24 00.00 12 EMBANKMENT.

2.2.1 Hand Tampers

PART 3 EXECUTION

3.1 STRUCTURAL EXCAVATION AND BACKFILL

3.1.1 General

The Contractor shall make all excavations required for the construction of the floodwall monoliths. Suitable material from required structural excavation shall be used in the structural backfill. Materials determined to be unsuitable by the Contracting Officer's Field Representative shall be ordered wasted.

3.1.2 Backfill

Backfill is defined as any soil material, which is placed within the limits of the structural excavation and the final grade as indicated on the drawings, and as herein specified. The Contractor shall fill all excavations to grades shown on the drawings. Backfill shall not be placed against concrete structures for a minimum of 14 days after the concrete is placed. The Contractor may at his expense place fill sooner if he furnishes and tests cylinders to demonstrate that the concrete has achieved 75 percent of its design capacity.

3.1.4.1 Compacted Backfill

Compacted backfill shall be compacted in accordance with Section

31 24 00.00 12 EMBANKMENT.

3.2 UNSUITABLE MATERIALS

Materials, which are classified as unsuitable structural backfill, are defined as material containing organic matter, sticks, branches, roots, brick, concrete, rock, and other debris.

3.3 FROZEN MATERIALS

Under no circumstances shall frozen earth, snow or ice be placed in the fill. The Contracting Officer may require the wasting of frozen material.

3.4 DRESSING

The fill shall be brought to not less than the prescribed design cross section at all points. Unreasonable roughness of surface shall be dressed out to permit fertilizing and seeding operations.

3.5 SHORING

The Contractor shall provide all necessary shoring, bracing, sheeting, underpinning, and/or supports as may be required for the construction of structures. A design and the method of installing the proposed shoring shall be submitted to the Contracting Officer for approval at least 30 days prior to its actual intended use. Upon completion of the structure, the Contractor shall remove the shoring at the direction of the Contracting Officer or his representative. The void created by the shoring removal shall be backfilled and the surface area shall be treated to match the existing surface prior to the installation of the shoring. Excavations more than 5 feet deep shall be shored unless shown otherwise on the drawings. Additional requirements for shoring shall be in accordance with Section 25 "Excavations" of EM 385-1-1.
