B. Earthwork shall be performed in accordance with the International Building Code and the drawings and specifications.

1.2 JOB CONDITIONS

A. Locate existing underground utilities in areas of work. If utilities are to remain in place, provide adequate means of support and protection during earthwork operations.

B. Should uncharted, or incorrectly charted, piping or other utilities be encountered during excavation, contact the COR or PI immediately for directions. Cooperate with COR and PI in keeping respective services and facilities in operation. Repair damaged utilities.

C. Do not interrupt existing utilities serving facilities occupied and used by the Government or others, during occupied hours, except when permitted in writing by the COR and then only after acceptable temporary utility services have been provided.

D. Barricade open excavations occurring as part of this work and post with warning tape.

E. Protect structures, utilities, sidewalks, pavements, trees, and other facilities from damage caused by settlement, lateral movement, undermining, washout and other hazards created by earthwork operations.

2.1 MATERIALS:

A. General Fill shall be soils free of organics and other deleterious materials, with a maximum liquid limit of 40, Plasticity Index between 5 and 20, maximum particle size of 3".

3.1 SUBGRADE TREATMENT

A. All subgrade areas to receive General Fill, or Engineered Fill shall be stripped of a minimum of 6 inches of vegetation, roots, topsoil, and soft soils, and compacted.

B. General Fill shall be placed in no greater than 8" thick lifts and compacted to a comparable level of at least 93% of maximum dry density as determined by ASTM D- 698 (Standard Proctor) at -1 to +3% optimum moisture content.

3.2 EXCAVATION

A. Excavation is unclassified. Excavate to subgrade elevations regardless of material encountered, including rock, soil materials and obstructions.

B. Unauthorized excavation consists of removal of materials beyond indicated subgrade elevations or dimensions without specific direction of COR. Unauthorized excavation as well as remedial work shall be at Contractor’s expense.

C. Excavation for structures shall conform to elevations and dimensions shown within a tolerance of plus or minus 0.1', and extending a sufficient distance from footings for placing and removal of concrete form work, other construction, and for inspections.

3.3 COMPACTION

A. Where subgrade or layer of fill material must be moisture conditioned before compaction, uniformly apply water to surface of subgrade, or layer of soil material, to prevent free water appearing on surface during or subsequent to compaction operations.

B. Do not place fill material on surfaces that are muddy, frozen, or contain frost or ice.

C. Place fill materials evenly adjacent to structures or piping to required elevations. Take care to prevent wedging action of backfill against structures or displacement of piping by carrying material uniformly around structure or piping to approximately same elevation in each lift.

F. Remove trash, debris and waste materials and dispose of legally off site.

G. Excess excavated material shall be removed from the construction site.

3.6 DEWATERING

A. Prevent surface water and ground water from entering excavations, from ponding on prepared subgrades, and from flooding Project site and surrounding area.

1. Reroute surface water runoff away from excavated areas. Do not allow water to accumulate in excavations. Do not use excavated trenches as temporary drainage ditches.

2. If required to keep subgrades dry and convey ground water away from excavation, install a dewatering system. Maintain until dewatering is no longer required.

set, the surfaces of the set concrete shall be thoroughly cleaned of laitance, coatings, foreign matter, and loose particles. Forms shall be re-tightened. The cleaned surfaces shall be moist but shall be without free water when grout is applied. Apply an even coat of neat cement grout to old concrete surfaces before placing new concrete.

3.8 CURING

A. Concrete shall be protected against moisture loss, rapid temperature change, mechanical injury from rain or flowing water, for the following period: Concrete shall be maintained in a moist condition at temperatures above 50 degrees F for the first 7 days or not less than 70 degrees F for the first 3 days. Concrete shall be protected from local application of heat. Curing activities shall be started as soon as free water has disappeared from the surface of the concrete after placing and finishing.

B. Moist Curing: Unformed surfaces shall be covered with burlap or mats, wetted before placing, and overlapped at least 6-inches. Burlap or mats shall be kept continually wet and in intimate contact with the surface. Where formed surfaces are cured in the forms, the forms shall be continually wet. Burlap shall be used only on surfaces that will be unexposed in the finished work and shall be in 2 layers.

The compound shall be applied in a two coat, continuous operation at a coverage of not more than 175 square feet per gallon for each coat. The compound shall form a uniform, continuous, adherent film that shall not check, crack or peel, and shall be free from pinholes or other imperfections. Membrane curing compound shall not be used on surfaces that are to receive any subsequent treatments that depend on adhesion or bonding to the concrete, or that are to receive floor hardener. Compound shall not be applied when the wind velocity exceeds 5 miles per hour.
