A. Control excavation to prevent water from running in. Do not obstruct surface drainage or existing waterways with stockpiles.

3.04 DEWATERING:

A. Provide and maintain devices at all times during construction to remove and dispose of all water from any source from all excavations. Use methods which will ensure dry excavations and preserve the final lines and grades of the excavation. Methods used may include well points, sump pumps, suitable rock or gravel drains, temporary pipelines, or other acceptable means.

B. Commence dewatering when water is first encountered and continue until construction is complete.

Dewater so that floor or footing concrete will not be placed in water. Do not allow water to rise against walls or above footings and slabs.

3.05 EXCAVATION AND TRENCHING:

A. General: Perform all material conditioning and excavations required. Excavation includes the removal and selected disposal of all excess or unsuitable materials of whatever nature.

PG 12 OF 28

maintain embankments during construction. Replace all materials lost due to storm or flood damage. Use materials obtained during excavation or borrow materials. Do not use brush, sod, or other unsuitable materials in embankments.

C. When an embankment is to be placed against an existing embankment whose slopes are steeper than 5:1, the existing slope shall be continuously benched, and the new embankment constructed in uniform lifts. Benching shall be of sufficient width to permit operations of placing and compacting equipment. Each horizontal cut shall begin at the intersection of the original ground and the vertical sides of the previous cuts. Material thus cut out shall be recompacted along with the new embankment material.

D. No embankment shall be constructed on or of frozen material, nor shall organic material be used for embankment.

E. Placement: Place material in loose lifts not exceeding 9 inches, brought to within 0% to +4% of optimum moisture content. Bring up each lift uniformly over the entire area being filled. Compact each layer to 95% of maximum dry density as determined by ASTM D698 as it is placed.

F. Make provisions for proper drainage during construction on the surface by sloping at approximately

2%. Maintain this slope during the entire construction procedure and maintain the proper moisture content in the uppermost layer. If placing of materials is interrupted and the material dries, bring to proper moisture content before resuming by sprinkling, cultivating, and rolling to the required compaction. Do not place or roll material during rainfall of sufficient intensity to materially increase the moisture content. If any material placed in embankment acquires a greater moisture content than is suitable for compaction, allow to dry or remove. If removed, recondition the new surface before placing new material. Repair any irregularities caused by erosion by excavating, cultivating, filling, and compacting.

3.10 STRUCTURAL EXCAVATION:

A. General: Structural excavation is the removal of all materials of whatever nature to approved structural subgrade and as necessary for construction of structures and foundations. Approved structural subgrade is that material which has been observed by the Engineer and upon which structural foundations or other materials may be placed.

B. Locate limits of excavation for structures with formed vertical surfaces at least 5 feet from the extreme outside of the structure to the toe of the cut slope. Where excavation is inadvertently carried beyond the design elevations or approved structural subgrade, adjust the construction as directed to meet the structural requirements.

C. Rectify over depth excavation in such locations by backfilling with crushed rock bedding material compacted to 95% maximum density or concrete as required by the Engineer.

D. Design and install shoring if necessary. Side slopes of excavation shall be only as steep as is safe

PG 13 OF 28

for material to stand. Avoid unnecessary disturbance of adjacent ground.

3.11 SUBGRADE FOR STRUCTURES:

A. Removal all existing loose natural clays, sand, and compressible materials under proposed structures. Excavate to depths indicated.

B. Following excavation, scarify next 8 inches of soil, moisture condition, and recompact to 95% of maximum density at a moisture content of 0% to +4% of optimum.

C. Fill all voids with aggregate material. Remove any disturbed or unacceptable materials at excavated foundation levels and replace with aggregate material. Carefully make excavations to avoid ponding of water.

D. Exercise careful excavation procedures to provide a relatively smooth subgrade.

3.12 BACKFILL AROUND STRUCTURES:

A. Use native materials for backfill material around structures as indicated on drawings. Place backfill in 9-inch loose lifts and compact to 95% of maximum density at a moisture content within 0% to +4% of optimum in accordance with ASTM D 698.

B. Do not use any axle-driven or tractor-drawn compaction equipment within five (5) feet of any structure.

3.13 COMPACTION:

A. Obtain compaction of backfill and embankment by mechanical means with compaction equipment or other equipment approved by the Project Manager. Pad foot rollers on an excavator, walk behind or remote trench compactors, and jumping jack type compactors are all acceptable means of compaction for this project. Do not use water jetting, hydraulic fill, or flooding. Compact each layer with mechanical tampers. Do not place backfill against concrete walls until design strength of concrete has been reached.

3.14 DISPOSAL OF UNSUITABLE MATERIAL:

A. Material not suitable for embankment, fill or backfill may be disposed of on-site at a location determined by the Owner. Transportation of such material shall be provided by the Contractor.
