PART 3 - EXECUTION

3.1 CLEARING

Perform clearing and grubbing including the excavation, removal and disposal of sod or any organic material and buried debris from within construction limits. Remove unsuitable material to at least 6 inches (30cm) below subgrade elevation.

Stockpile for project use any topsoil removed by clearing and grubbing (6 inch minimum). Restrict topsoil stockpile areas to areas designated for seeding in the contract. Ground surface disturbed outside of designated areas will be restored to original condition or better and seeded at no cost to the Government.

Dispose of all clearing material as specified in Section 3.3 below.

3.2 EXCAVATION

Excavate to the specified lines and grades. Excavate without causing rutting, pumping or other disturbance to underlying materials.

Correct subgrade disturbance by hand or machine methods to form a uniform grade. Correct subgrade disturbance before placing overlying fill, topsoil, backfill, base course or other courses.

Maintain the subgrade to drain at all times. Construct side ditches or gutters from cuts to embankments to prevent erosion damage to embankments.

Construct and maintain temporary drainage where existing surface drainage, sewers, or under-drainage are disturbed during the work until permanent drainage facilities are completed. Protect and preserve all existing drains, sewers, sub-surface drains, conduits, gas lines, and other underground structures which may be affected by the work. Repair all damage to these facilities or structures resulting from the work at no cost to the Government.

The contractor shall use a non-destructive means (hydro-vac) to locate and identify all above or below ground utilities PRIOR to excavation. If any interference should arise with utilities and the contract required work, the contractor shall notify government prior to work starting. EX: Utility conflict with new berm constructed around building.

3.3 DISPOSAL OF EXCESS EXCAVATED MATERIAL

A. General. Assure the subgrade beneath pavements is natural soil free of topsoil, organic material or refuse. Place pavement components over the prepared subgrade as soon as practical. Do not place pavement components on frozen subgrade. No separate payment is made for subgrade preparation, since it is considered incidental to construction of overlying pavements/structures.

B. Fine Grading. Assure the finished surface does not deviate not more than 0.1 foot (3cm) at any point from the staked elevation; and that the sum of the deviations from true grade of any two points less than 30 feet (9m) apart does not exceed 0.1 foot (3cm).

C. Compact the fill and subgrade underlying sidewalks, curb and pavement subgrade to at least 95% of the laboratory maximum determined by AASHTO T99.

E. Sub-excavation and replacement. Sub-excavation and replacement is removing and replacing unstable material below the plan subgrade elevation. The Project Inspector will identify the location, extent and depth of any sub-excavation that may be required. Dispose of materials removed as per Section 3.3. Replace removed material with a suitable granular material having a maximum size of 3 inches with 65-90 percent passing the ¾” sieve, 25-60 percent passing the No.

4 sieve, 20-50 percent passing the No. 10 sieve, and not more than 12 percent passing the No.

200 sieve and a maximum PI of 6. This work is a separate pay item.

3.5 PROTECTION OF THE WORK

Assure the finished grade does not deviate more than 0.1 foot at any point from the staked elevation and the sum of the deviations from true grade of any two points not more than 30 feet apart does not exceed 0.1 foot.

Do not place any surface course or pavement until the subgrade has been checked and found acceptable by the Project Inspector.
