The Government reserves the right to increase or decrease the foundation widths and embankment slopes or to make such other changes in the embankment sections as may be deemed necessary to produce a safe structure. Changes in quantities resulting from such revisions will not constitute justification for change in contract unit prices, except as provided for in the Variations in Estimated Quantities Clause.

3.1.2 Conduct of the Work

Maintain and protect the embankment in a satisfactory condition at all times until final completion and acceptance of all work under the Contract. If, in the opinion of the Contracting Officer, the hauling equipment causes horizontal shear planes or slicken sides, rutting, quaking, heaving, cracking, or excessive deformation of the embankment or backfill, limit the type, load, or travel speed of the hauling equipment on the embankment or backfill. The Contractor may be required to remove, at no additional payment, any embankment material placed outside of prescribed slope lines. Any approved embankment or backfill material which is lost in transit or rendered unsuitable after being placed in the embankment or backfill and before final acceptance of the work shall be replaced in a satisfactory manner and no additional payment will be made therefore. Excavate and remove from the embankment or backfill any material which is unsatisfactory, dispose of such material, and refill the excavated area as directed, all at no cost to the Government.

3.2 DEWATERING AND DIVERSION

Surface and groundwater control shall be accomplished in coordination with the required excavation and embankment construction. Surface and/or groundwater control may necessitate the use of temporary diversion ditches, cofferdams and/or dewatering by the use of pumping. Methods for care of surface water and for controlling the surface and groundwater levels shall be subject to approval of the Contracting Officer.

3.3 EXCAVATION

Excavation shall consist of removal of material in preparing the foundations to the lines and grades shown on the drawings, removal of material from ditches and channels to the lines and grades shown on the drawings, removal of objectionable materials and obtaining required fill materials from the borrow areas. Blasting will not be permitted. Over excavation shall be backfilled to grade with similar over excavated material or satisfactory material and compacted to a density of at least that of the surrounding material. Submit a written excavation plan 30 days prior to the beginning of any excavation. Approval of the detailed plan shall be obtained from the Contracting Officer prior to starting the work. If necessary, modify the plan as required to meet field conditions, and the modifications shall be approved prior to use. As a minimum, the plan shall contain the following:

3.9 PREPARATION OF FOUNDATION, PARTIAL FILL SURFACES AND ABUTMENTS

3.9.1 Earth

After excavation (as described in paragraph EXCAVATION) or stripping (as described in section 31 14 13.23 45 STRIPPING) of the embankment foundation to the extent indicated or otherwise required, the sides of cavities or depressions shall be broken down so as to flatten out the slopes, and the sides of the cut or hole shall be scarified to provide bond between the foundation material and the fill. Unless otherwise directed, each depression shall be filled with the same material type that is to be placed immediately above the foundation. The fill shall be placed in layers, moistened, and compacted in accordance with the applicable provisions of paragraphs PLACEMENT, MOISTURE CONTROL, and COMPACTION for the specific material type. Materials which cannot be

SECTION 35 41 00 Page 12 compacted by roller equipment because of inadequate clearances shall be compacted with power tampers in accordance with the paragraph COMPACTION for the specific material type. After filling of depressions and immediately prior to placement of compacted fill in any section of the embankment, the foundation of such section shall be loosened thoroughly by scarifying, plowing, discing or harrowing to a minimum depth of 6 inches , and the moisture content shall be adjusted to the amount specified in paragraph MOISTURE CONTROL for the appropriate type of material.

Immediately prior to placement of compacted fill on or against the surfaces of any partial fill section, all soft or loose material, all material containing cracks or gullies, and all material that does not conform with the specified zoning of the embankment shall be removed. The remaining surface of the partial fill shall be loosened by scarifying, plowing, discing or harrowing to a minimum depth of 6 inches , and the moisture content shall be adjusted as specified in paragraph MOISTURE CONTROL for the appropriate type of material. The surface of the partial fill section upon which fill is to be placed shall then be compacted as hereinafter specified for the appropriate type of fill. No separate payment will be made for loosening and rolling the foundation area, the abutment area, or the surfaces of partial fill sections, but the entire cost thereof shall be included in the applicable contract price for fill.

3.10 TEST FILL STRIPS

3.10.1 General

Before beginning embankment construction, construct test strip(s) for select and semicompacted fill materials to demonstrate that the equipment and compaction procedure will achieve the moisture-dry density relationship as specified. The test strips may be incorporated as part of the final embankment, if the fills meet the requirements of the specifications. The test strips for select fill materials shall be constructed using materials from the borrow sources which have been approved by the Contracting Officer. Test strips for semicompacted fill shall be constructed using soils excavated from the site (AM#3)or materials from the borrow site which are approved by the Contacting Officer. A test strip shall be performed for each of the following types of fill materials; select fill and semicompacted fill. Each test strip shall be of sufficient size to allow compaction equipment to achieve normal operating speed over a 50 foot length. The test strip shall be a minimum of two (2) times wider than the compaction equipment. Each test strip shall be constructed with a minimum of 4 lifts. Prior to the construction of the test strips, the foundation (subgrade) shall be proof rolled and an 8 inch thick subbase layer installed. The subbase layer shall consist of the same material to be used in the test strip and shall be spread and compacted to the same requirements. The test strips shall be constructed in accordance with the applicable provisions of paragraphs PLACEMENT, MOISTURE CONTROL, and COMPACTION for the specific material type. The fill material shall be placed and spread in layers in accordance with the applicable provisions of paragraphs PLACEMENT for the specific material type. Each layer of the fill shall be compacted with a minimum of four (4) complete coverages using the specified compaction equipment, and as many additional coverages as may be required to achieve the specified density. Even if the results from the test strips show that the required densities can be obtained with less than four coverages by the compaction equipment, compaction of the select and semicompacted fills with a minimum of (4) complete coverages is still required. If the use of the proposed compaction equipment causes shearing of the fill, laminations in the fill, or results in inadequate compaction, the Contracting Officer

SECTION 35 41 00 Page 13 may direct that such roller be removed from the fill and that another appropriate tamping roller be used.

3.10.2 Testing and Reporting Requirements for Test Strips

Prior to construction of the test strips, perform one laboratory compaction test for each type of material used in test strips. The compaction tests shall be performed in accordance with the requirements specified in paragraph MATERIALS TESTING. Test results shall be submitted to the Contracting Officer before construction of the test strips. After placement and spreading of the fill in the test strip, but prior to compaction, five samples shall be obtained from each lift for moisture content determination in accordance with ASTM D2216. Use nuclear density testing equipment in accordance with ASTM D6938. In addition, the following condition shall apply:

a. Prior to using the nuclear density testing equipment on the site, submit to the Contracting Officer a certification that the operator has completed a training course approved by the nuclear density testing equipment manufacturer, the most recent data sheet from the manufacturer's calibration, and a copy of the most recent statistical check of the standard count precision.

b. The nuclear density testing equipment shall be capable of extending a probe a minimum of 6 inches down into a hole.

After compaction of the fill, a minimum of 5 in-place nuclear density and moisture content tests (in accordance with ASTM D6938) and one (1) sand cone density test (in accordance with ASTM D1556/D1556M ) shall be performed on each lift. One sample shall be obtained from each test strip for classification testing as specified in paragraph MATERIALS TESTING.

All testing and sampling locations shall be determined by the Contracting Officer. The Contractor's QC personnel shall monitor and document construction and testing of the test strips. Documentation shall include weather conditions, soil type, spreading and compaction equipment type, lift thickness, number of coverages, moisture content, dry density, and a plan showing approximate location of sampling and testing. Documentation of the test strip construction procedures and results of all testing shall be provided to the Contracting Officer. Full scale embankment construction shall not commence until the equipment and placement methods are approved by the Contracting Officer.

3.11 PLACEMENT AND SPREADING

3.11.1 General

Prior to beginning embankment placement on the levee foundation, notify the Government that the foundation is ready to receive fill. No fill shall be placed on any part of the embankment foundation until such areas have been inspected and given final approval by the Contracting Officer.

3.11.1.1 Gradation and Distribution

The gradation and distribution of materials throughout each zone of the levee shall be such that the embankment will be free from lenses, pockets, streaks, and layers of material differing substantially in texture or gradation from surrounding material of the same class. If lenses, pockets, or layers of materials differing substantially in texture or gradation from surrounding material occur in the spread material, the

SECTION 35 41 00 Page 14 layer shall be mixed by harrowing or any other approved method to blend the materials. During the placing and spreading process, maintain at all times a force of workers adequate to remove all roots, debris, and oversize stone from all embankment materials. All stones and rock fragments larger than 1 inches in any dimension shall be removed at the source prior to hauling from the fill source. No fill shall be placed upon a frozen surface, nor shall snow, ice, or frozen earth be incorporated in the embankment.

3.11.1.2 Foundations and Partial Embankment Fills

The foundations and all partial embankment receiving fills shall be kept thoroughly drained. Placing operations will be such as to avoid mixing of materials from adjacent sections as much as practicable.

3.11.1.3 Equipment Traffic

Equipment traffic on any embankment zone shall be routed to distribute the compactive effort as much as practicable. Ruts formed in the surface of any layer of spread material will be filled before that material is compacted.
