PROJECT MANUAL
Version: January 2012
i. Classification of Materials: Material to be excavated is unclassified. Contractor
shall visit and determine for himself classification of the materials to be removed.
NO EXTRA PAYMENT will be made for rock excavation.
b. Unauthorized Excavation: Unauthorized excavation consists of removal of the material
indicated below elevations without specific direction of the Architect. Replace
unauthorized excavation as herein specified. Excavations from footing carried below
elevations indicated on drawings shall be filled with specified footing type concrete at
Contractor's expense. Excavations carried below the grades indicated for trenches shall
be backfilled with suitable soil or select fill at Contractor's expense.
c. Dewatering:
i. Perform earthwork and site grading in a manner to prevent surface water and
sub grade or ground water from flowing into excavations, and to prevent water
from flooding the project site and surrounding area.
ii. Do not allow water to accumulate in excavations. Remove all water from
excavations using dewatering methods, which will prevent softening of
foundations bottoms, undercutting footings, and soil changes detrimental to
stability of the sub grades and foundations. Provide and maintain pumps,
sumps, suction and discharge lines, and other dewatering components
necessary to convey water away from the site.
iii. Convey water removed from excavations and rainwater to collecting or runoff
areas. Provide and maintain temporary drainage ditches and other diversions.
Do not use trench excavations for site utilities as temporary drainage ditches.
d. In no case shall "water settling" or jetting be employed.
3.03 BACKFILL AND FILL
a. General:
i. Backfill consists of the placement of specified backfill material in layers, in the
excavations to the required sub grade elevations.
ii. Fill consists of the placement of specified fill materials, in layers, over the ground
surface to the required elevations.
b. Backfill and Fill Materials:
i. Provide satisfactory soil materials for backfill and fill. Use excavated or borrow
material that has been sampled, tested, and approved as satisfactory backfill and
fill material by the testing service.
c. Placement and Compaction: Place backfill and fill materials in layers not more than 8" in
loose depth. Before compaction, moisten or aerate each layer as necessary to provide
the optimum moisture content of the soil material. Compact each layer to the required
percentage of maximum density for each area classification. Do not place backfill or fill
material on surfaces that are muddy, frozen, or contain frost or ice.
