PART 3 EXECUTION

3.1 EXCAVATION

3.1.1 Classification

The condition of the material to be excavated, bored, drilled, etc., must be determined by the construction contractor. Excavation may require ripping, blasting, cutting, or other means beyond the use of a normal back hoe or drilling equipment.

3.1.2 Drainage

Excavation shall be performed so that the area of the site and the area immediately surrounding the site and affecting operations at the site will be continually and effectively drained. Water shall not be permitted to accumulate in the excavation. The excavation shall be drained by pumping or other satisfactory methods to prevent softening of the foundation bottom, undercutting of footings, or other actions detrimental to proper construction procedures.

3.1.3 Freezing

When freezing weather is expected, excavations shall not be made to the full depth, unless the footing concrete can be placed immediately. If excavation is already at full depth, the excavation shall be protected from frost.

3.1.4 Excavation for Slabs and Footings

The excavations shall conform to the dimensions and elevations of the drawings applicable to footings and other foundation structures which are cast in place.

3.1.4.1 Limits

Excavations below indicated depths shall not be permitted except to remove material consisting of shale, sod, clods, stones larger than 4 inches, organic debris, trash or frozen material. Such unsatisfactory material shall be removed to a depth of 6 inches and replaced with satisfactory fill material. Unauthorized over excavation for footings shall be replaced at no additional cost to the Government to the indicated excavation grade with concrete. Excavation shall extend a sufficient distance from footings to allow for placing and removal of forms, installation of services, and for inspection, except where the concrete for walls and footings is authorized by the Resident Engineer to be deposited directly against excavated rock surfaces.

02200 - PAGE 4

3.1.5 Trench Excavation

Trenches for direct earth burial cables, conduits and other utilities shall conform to the dimensions and elevations shown on the applicable drawings. The banks need not be kept vertical but may be sloped or widened to such general limits as may be set by the Resident Engineer, provided there is no interference with other utilities. The trench bottom shall be a minimum of 6 inches wide or as required to provide separation between power and control cables or between power cables of different voltages. The trench depth shall be deep enough to allow cable placement plus an over excavation of at least three inches. The over excavation shall be filled with earth or sand containing no material aggregate particles that would be retained on a 1/4-inch sieve. The fill material shall be compacted to approximately the same density of the adjacent soil.

3.1.6 Excavation for Walkways and Access Roads

The excavation shall conform to the dimensions and elevations of the drawings applicable to areas designed for vehicular and pedestrian traffic. Subgrade areas for access roads and walkways shall be plowed, disked and moistened or aerated as required obtain proper compaction. Muck, peat and other unsatisfactory material shall be removed to a minimum depth of 12 inches below excavation grade or as required to provide a satisfactory foundation. Low areas resulting from removal of such material shall be brought up to required grade with satisfactory fill material.

3.1.7 Excavation of Ditches, Swales and Culverts

Ditches, swales and culverts shall be cut accurately to the cross sections and grades indicated.

The sides and bottom of ditches and swales shall conform to the slope, grade, and shape of the section indicated. Care shall be taken not to excavate ditches and swales below the grades indicated. Excessive excavation shall be backfilled to the indicated excavation depth with approved material and compacted to 90 percent maximum density. All ditches, swales, and culverts excavated under this section shall be maintained until final acceptance of the work.

3.1.8 Safety and Protection of Work

Sheeting and shoring shall be done as may be necessary for the protection of the work and for the safety of personnel. The manner of bracing excavations shall comply with local regulations and OSHA construction regulations. Grading shall be performed in a manner to ensure proper drainage at all times.

3.1.9 Utilization of Excavated Materials

Satisfactory excavated material shall be used in the work insofar as practicable. No excavated material shall be disposed of in such a manner as to obstruct the flow of any stream, endanger a partly finished structure, impair the efficiency or appearance of any structure, or be detrimental to the completed work in any way.

02200 - PAGE 5

3.1.10 Inspection of Excavated Area

When excavations have reached the required elevations, the contractor shall not proceed with further construction of the excavated area until the area has been inspected by the Resident Engineer.

3.2 FILL AND BACKFILL

3.2.1 Weather Conditions

No fill or backfill operations shall be performed when weather conditions are determined by the Resident Engineer to be too wet or cold to permit such operations.

3.2.2 Satisfactory Material

Material suitable for fill, backfill and embankment purposes shall be reasonably free of shale, sod, clods, and stones larger than 4 inches, organic debris, trash and frozen material. Only materials suitable for obtaining the degree of compaction specified herein shall be used.

3.2.3 Preparation of Surface for Fill and Embankment

All surfaces designated to receive fill and embankment material shall be inspected prior to material placement. Soil surfaces on which compacted fill is to be placed shall be plowed, disked or otherwise broken up to a depth of 6 inches, pulverized, moistened or aerated as necessary, mixed and compacted to the same density as required for the fill or embankment material. Sloped ground surfaces steeper than one vertical to four horizontal on which fill is to be placed shall be stepped or benched, as directed, in such manner that the fill material will bond with the existing surface. The finished surface shall be reasonable smooth, compacted and free from irregular surface changes. The degree of finish shall be that ordinarily obtained from blade-grader operations or, where more suitable, hand raking.

3.2.4 Source of Fill Material

Fill material shall be selected for the particular fill area for which it is to be used. Fill material shall not be confused with surfacing aggregate. Necessary clearing, grubbing, and disposal of debris, shall be considered incidental operations to the borrow excavation and shall be performed by the contractor. All material stockpiled on site shall either be used as fill material or disposed of by the contractor.

3.2.5 Fill for Slabs and Foundations

Satisfactory material shall be placed in horizontal layers of 6 inches (loose measurement) and compacted to 95 percent maximum density. Unless directed by the Resident Engineer, no backfill shall be placed against footings prior to 7 days after footings and slabs are poured.

02200 - PAGE 6

3.2.6 Backfilling of Conduit Trenches

Trenches shall be backfilled as indicated on the drawings.

The disturbed area shall be cleaned, raked, and seeded. All trench backfilling shall be to the approval of the Airport Manager and the Project Engineer. THE CONTRACTOR SHALL

GUARANTEE THAT NO SETTLEMENT OCCURS WHICH LEAVES A DEPRESSION

BELOW THE SURROUNDING GRADE FOR A PERIOD OF ONE YEAR AFTER PROJECT

COMPLETION.

3.2.7 Fill and Embankment for Access Roads, Walkways, and Culverts

Fills and embankments shall be constructed at the locations and to lines and grades indicated on the drawings. The material shall be placed in successive horizontal layers of 8 inches, loose measure, for the full width of the cross section. Fills and embankments shall be compacted to 95 percent of maximum density. Final elevations after compaction shall not vary more than 0.05 feet from the established grade and approved cross section.

3.2.8 Fill for Open Areas

All open areas to receive seed or sod shall be filled to within 6 inches of final grade with satisfactory material. Fill beneath this layer shall consist of material free of rocks larger than 6 inches and shall be placed in layers not greater than 8 inches, loose measure. All layers shall be compacted to 90 percent maximum density.

3.2.9 Placing of Crushed Rock and Topsoil

On areas to receive crushed rock or topsoil material, the compacted fill or subgrade shall be scarified to a depth of 2 inches. Material to be placed shall then be evenly spread, graded and compacted to 90 percent of maximum density. Material required to be placed within two feet of footings or slabs shall be compacted by approved hand tampers. Compaction of topsoil to be grassed or sodded may be deferred until after seeding or sodding operations.

3.2.10 Compaction Methods

Compaction shall be performed using the method and equipment suitable for the area as specified. Mechanical hand tampers shall be used only in areas adjacent to footings and slabs or in trenches or other areas where use of rollers is not practical. Compaction with pneumatic-tired rollers, three wheel power rollers, sheepsfoot rollers, etc., shall be used in all other areas as required to provide the specified compaction density.

02200 - PAGE 7

3.2.11 Determination of Density

Maximum density tests will be performed in accordance with AASHTO-T99 and field density tests will be performed in accordance with AASHTO-T191, T204, T205, or T233.
