4.2.1.1 Test reports-excavating: Submit the following reports directly to the Contracting Officer from the testing services, with copy to Contractor:

4.2.1.1.1 Field density test reports for soils, aggregate, and asphalt.

4.2.1.1.2 One optimum moisture-maximum density curve for each type of soil encountered per MIL-STD-621A and ASTM D2216.

4.2.1.2 US Air Force’s in-house testing is the final arbiter for materials acceptance testing.

4.2.2 SOIL MATERIALS:

4.2.2.1 Backfill and Fill Materials: Satisfactory soil materials shall be free of rock or gravel larger than 50mm in any dimension, debris, waste, frozen materials, organics, and other deleterious matter.

4.2.2.2 Select granular material shall consist of well-graded sand composed of hard, tough and durable particles, and shall not contain more than 10 percent by weight of material passing the 0.075mm sieve, with a maximum allowable particle size of 5mm.

4.2.2.3 Foundation Bedding Material for dig-outs, storm sewers and utility work shall be used when soft or unstable material unable to support the utility pipe, conduit or appurtenant structure is encountered. The unstable material shall be excavated and replaced with sound bedding material.

4.2.3 EXCAVATION:

4.2.3.1 Excavation for the grading and trenching includes excavation to sub-grade elevations indicated, regardless of character of materials and obstructions encountered. Material excavated at the site may be considered usable for grading and backfill purposes subject to the requirements of Paragraph 4.2.2 of this statement of work. The Contractor shall furnish any additional fill required to complete the grading or dispose of excess excavated material at his expense.

4.2.3.2 Unauthorized excavation consists of removal of materials beyond indicated sub-grade elevations or dimensions without specific direction from the Contracting Officer.

Unauthorized excavation, as well as remedial work directed by the Contracting Officer shall be at the Contractor's expense.

4.2.3.3 Excess Material Disposal: All unsatisfactory materials removed from excavations shall be disposed of in designated waste disposal or spoil areas. Satisfactory material removed from excavations shall be used, insofar as practicable, in the construction of fills, embankments, sub-grades, shoulders, bedding (as backfill), and for similar

FA5706-15-R-0005

14-0115 CONSTRUCT BC3-T COMMAND SUPPORT FACILITY Page 12 of 26 purposes. No satisfactory excavated material shall be wasted without specific written authorization. Satisfactory material authorized to be wasted shall be disposed of in designated areas approved for surplus material storage or designated waste areas.

4.2.3.4 Utility Trenching:

4.2.3.4.1 All Trenching shall be accomplished by hand to avoid any damage to existing utilities.

4.2.3.4.2 The US Government shall provide the location of known underground utilities; however, the Contractor shall maintain awareness that there may be some unknown buried utilities. The Contractor shall repair to like-new condition any utilities damaged by construction activity.

4.2.3.4.3 The Contractor shall notify the Contracting Officer immediately if unexpected obstacles, such as existing utilities, structures, trees, or other fixed features are encountered during construction.

4.2.3.4.4 All utility work shall be inspected by US Government Representative prior to covering.

4.2.3.4.7 After trenching, the Contractor shall restore the existing surface to its original finished condition.

4.2.3.5 Stability of Excavations: Contractor shall comply with all American OSHA regulations with regards to worker safety in trenches. The Contractor shall bench the sides of excavations to comply with applicable codes and safety regulations and maintain trench walls and benches in a safe condition until completion of backfilling. The Contractor shall shore and brace excavations where sloping is not possible because of space restrictions or stability of material excavated. The Contractor shall prevent surface water and subsurface or ground water from flowing into excavations and from flooding the project site and the surrounding area. For excavations over 100 m2 in surface area, the Contractor shall grade the top perimeter of the excavation to prevent surface water from draining into the excavation. For excavations less than 100 m2, small hand formed “berms” or sandbags around the perimeter may suffice. For work that will be completed in the same day and for which there is little danger of surface water run-off, special grading or sandbags is not required. The Contractor shall not allow water to accumulate in excavations. The Contractor shall remove water from excavations to prevent softening or loss of stability of the sub-grade. The Contractor shall provide and maintain pumps, well points, sumps, suction and discharge lines, and other dewatering system components necessary to convey water away from excavations.

4.2.3.6 Material Storage: The Contractor shall stockpile satisfactory excavated materials in areas approved by the Contracting Officer until required for backfill or fill.

4.2.3.7 The Contractor shall place, grade, and shape stockpiles for proper drainage.

4.2.4 COMPACTION:

4.2.4.1 General: The Contractor shall control soil compaction during construction providing the minimum percentage of density as specified in this statement of work and on the construction drawings. Density shall be tested using the sand cone method per ASTM D1556.

4.2.4.2 Moisture Control: Where sub-grade or layer of soil material must be moisture conditioned before compaction, uniformly apply water to surface of sub-grade, or layer of soil material to prevent free water appearing on surface during or subsequent to compaction operations. Soil material that is too wet to permit compaction to the specified density shall be removed and replaced or scarified and air dried at the Contractor’s expense.

Soil material that has been removed because it is too wet for proper compaction may be stockpiled or spread; thereby, allowed to dry at the Contractor’s expense. Optimum and in-situ soil moisture shall be determined by MIL-STD-621A and ASTM D2216.

4.2.6 CONSTRUCTION:

4.2.6.1 The Contractor shall shape the sub-grade to the required line, grade, and cross section, and compact as specified. This operation shall include plowing, disking, and any moistening or aerating required in order meeting the specified compaction at optimum moisture. The Contractor shall be responsible for aerating or replacing existing soils that are too moist or too weak to support construction equipment.

4.2.6.2 The surface of the sub-grade shall not show deviations greater than 13mm when tested with a 3m straightedge applied both parallel and at right angles to the centerline of the area. The elevation of the finished sub-grade shall not vary more than 15mm from the established grade and cross section.

4.2.6.3 The Contractor shall remove and replace soft or otherwise unsatisfactory material with satisfactory excavated material or other approved material as directed. Low areas resulting from removal of unsatisfactory material or excavation of rock shall be brought up to required grade with satisfactory materials, and the entire sub-grade shall be shaped to line, grade, and cross section and compacted as specified.

4.2.7 GRADING AND RESTORATION:

4.2.7.1 Finishing: The Contractor shall finish all the unpaved areas to a smooth and compact surface in accordance with the lines, grades, and cross sections or elevations shown.

4.2.8.1 The Contractor shall repair and re-establish grades in settled, eroded, and rutted areas to the specified tolerances.

4.2.8.2 Reconditioning Compacted Areas: Where completed compacted areas are disturbed by subsequent construction operations or adverse weather; then, the Contractor shall scarify the surface, reshape, and compact in order to meeting the required density prior to further construction.

4.2.8.3 Settling: Where settling is sufficient to cause ponding water over 13mm in depth on paved areas or 25mm in depth on turfed areas during the general project warranty period, the Contractor shall remove the surface (pavement, lawn or other finish), and replace according to the original specifications.

4.2.8.4 The Contractor shall restore the appearance, quality, and condition of the surface or finish to match adjacent work, and eliminate evidence of restoration to the greatest extent possible.
