PART 3- EXECUTION.

3.1 EXCAVATION: The Contractor shall perform excavation of every type of material encountered within the limits of the project and below the existing concrete to the depth and grade necessary to install the new pavement section. Grading shall be in conformity with the typical sections shown and the tolerances specified in paragraph FINISHING AND PROTECTING WORK. Satisfactory excavated materials shall be transported to and placed in fill areas within the limits of the work. Unsatisfactory materials encountered within the limits of the work shall be excavated below grade and replaced with satisfactory materials as directed. Surplus satisfactory excavated material not required for fill or embankment shall be disposed of off-base or to an on-base location when instructed by the Contracting Officer. During construction, excavation and filling shall be performed in a manner and sequence that will provide proper drainage at all times. Material required for till in excess of that produced by excavation within the grading limits, shall be excavated from borrow areas off base.

A. Protection of Existing Underground Utilities: Utility lines that are located on the site shall be protected from damage during excavation and backfilling and, if damaged, shall be repaired by the Contractor at no expense to the Government. In the event that the Contractor damages existing utility lines that are not shown on the plans, or the locations of which have not been made known to the Contractor, such repairs will be ordered.

02223-2

Equitable payment will be negotiated at that time. When known utility lines that are to be removed are encountered within the area of operations, the Contractor shall notify the Contracting Officer in ample time for the Government shop personnel to remove the utility.

B. Removal of Unstable Material: When determined by the Contracting Officer that the subgrade will not provide a stable foundation for construction purposes, the Contractor will be directed in writing to remove such native soil as ‘unstable material” and replace it with satisfactory material.

Removal of unstable material includes replacement with satisfactory fill material or with native material after it has been removed and undergone such manipulation as to achieve optimum moisture content. Moisture content reduction may consist of aeration or other moisture reduction methods as approved by the Contracting Officer. Replacement material shall be placed and compacted as specified hereinafter. Material in which the moisture content can be reduced by normal construction operations will not be considered as unstable materials. When the Contractor, due to negligence, poor scheduling, or failure to take appropriate remedial actions, allows subgrade material to become unstable, he shall remove and replace all unstable material at no additional cost to the Government.

C. Opening and Drainage of Excavation: The Contractor shall notify the Contracting Officer sufficiently in advance of the opening of any excavation to permit elevations and measurements of the undisturbed ground surface to be taken. Except as otherwise permitted, excavation areas shall be excavated in such a manner as to insure free drainage.

3.2 BACKFILL:

A. Backfill adjacent to any and all types of structures shall be placed in maximum 8- inch loose layers and compacted to at least 95% maximum dry density. In situ material shall be compacted to 90% of maximum laboratory value. This operation shall include plowing, disking, and any moistening or aerating required to obtain proper compaction. When a lift of soil is below the minimum specified density, the lift shall be scarified, aerated, smoothed, and compacted to the proper density. Compaction shall be accomplished by vibratory rollers, sheepsfoot rollers, pneumatic-tired roller, steel-wheeled rollers or other approved equipment. Hand operated vibratory compactors shall be used adjacent to existing pavement designated to remain.

B. Utilization of Excavated Materials: All unsatisfactory material removed from excavations shall be disposed of off-base unless designated otherwise by the Contracting officer for an on-base location. Satisfactory material removed from excavations may be used, at the Contractor’s option, in the construction of fills and subgrades and for similar purposes. The Contractor may utilize borrow material in lieu of aeration at no additional cost to the Government.

C. All earthen materials adjacent to concrete pavements shall be one inch below finished grade of concrete pavement edges.
