1, SCOPE OF WORK
A. Extent: The work required under this section
consists of oil excavating, filling, rough grading
and related items necessary to complete the work
indicated on the drawings and described in the
specifications. The Controctor shall notify in
writing the owners and the Engineer of any changes,
errors, or omissions found on the plans or in
the field, before work is started or resumed,
1, in general, the items of work to be
performed under this section shall include:
clearing and grubbing, removal of trees and
stumps (where required), protection of trees
to remain, stripping and storage of topsoil,
fill compaction and rough grading of entire
site.
2. Excavated material that is suitable may be
used for fills. All unsuitable material and
oil surplus excavated material not required
shall be removed from the site. The
location of dump and length of haul shall be
the Contractor's responsibility.
3, Provide and place any additional fill
material from off the site as may be
necessary to produce the grades required.
Fill obtained from off site shall be of kind
and quality as specified for fills herein
and the source approved by the Owner.
4. The Contractor shall accept the site as he
finds it and shall remove all trash, rubbish
and debris from the site prior to starting
excavation.
B, Work not included: The following items of
related work are specified and included in other
sections of these specifications:
1. Excavation, grading and backfilling for
utility lines
2. Storm drainage systems
3. Sanitary sewer systems
4. Streets and paving
5, Water supply system
2. BENCH MARKS
Maintain carefully all bench marks, monuments and other
reference points; if disturbed or destroyed, contractor
shall contact engineer.
3, REMOVAL OF TREES
A. Remove all trees and stumps from area to be
occupied by rood and surfaced areas. Removal of
trees outside these areas shall only be done as
noted on drawings or approved by the Owner.
B. All brush, stumps, wood and other refuse from the
trees shall be buried onsite or removed to disposal areas
off of the site. Disposal by burning shall not
be permitted unless proper permits are obtained
(where applicable). The location of on site bury
pits shall be designated by the owner or the
Engineer.
4. PROTECTION OF TREES
A, General Protection: The Contractor shall be
responsible for the protection of tops, trunks
and roots of existing trees on the project site
that are to remain. Existing trees subject to
construction damage shall be boxed, fenced or
otherwise protected before any work is started;
do not stockpile within branch spread. Remove
interfering branches without injury to trunks and
cover scars with tree paint.
5. HANDLING OF TOPSOIL
A. Remove all organic material from the areas to be
occupied by buildings, roads, walks and parking
areas. Pile and store topsoil at a location
where it will not interfere with construction
operations. Topsoil shall be reasonably free
from subsoil, debris, weeds, gross, stones, act.
B. After completion of site grading and subsurface
utility installation, top soil shall be replaced
in areas designated on the erosion control plan
for seeding and/or sodding. Any remaining top
soil shall be used for finished grading around
structures and landscaping areas.
6, DISPOSITION OF UTILITIES:
A. Rules and regulations governing the respective
utilities shall be observed in executing all work
under this section.
B. If active utilities are encountered but not shown
on the drawings, the Engineer shall be advised
before work is continued.
C. inactive and abandoned utilities encountered in
excavating and grading operations shall be
reported to the Engineer. They shall be removed,
plugged or capped as directed by the Utility
Company and the Engineer.
D. It shall be the responsibility of each contractor
to verify oil existing utilties and conditions
pertaining to his phase of the work. It shall
also be the contractors responsibility to contact
the owners of the various utilities before work
is started.
7. SITE GRADING:
A. Grodes: Contractor shall perform oil cutting,
filling, compacting of fills and rough grading
required to bring entire project area to grade as
shown on the drawings.
B. Rough Grading: the tolerance for paved areas
shall not exceed 0.04 feet plus or minus above
the established subgrode. All other areas shall
not exceed 0.10 feet plus or minus the
established grade. All banks and other breaks in
grade shall be rounded at top and bottom.
C. Compaction Requirements:
1. All building pod areas shall be compacted to
standards specified by local and/or state
building codes.
2, For compaction requirements of paved areas,
see street specifications.
4
5 1 6
8. Earth Work Balance
The Contractor shall confirm all eorthwork quantities
prior to start of construction. if an excess or
shortage of earth is encountered, the Contractor shall
confirm with the Owner and Engineer the requirements
for stockpiling, removal or importing of earth.
Minor adjustments to the grades may be required to
earthwork balances when minor excess material or
shortages ore encountered. It is recognized by the
parties hereto that the calculations of the Engineer
in determining eorthwork quantities shall be ac-
complished in accordance with the American Society of
Civil Engineers Standards for such calculations.
Further, that these calculations are subject to the
interpretations of soil borings as the physical limits
of the various soil types, also the allowable variation
in finish grade and compaction permitted the contractor,
and that all of these parameters may cause either an
excess or shortage of actual earthwork materials to
complete the project. If such on actual minor excess or
shortage of materials occurs, the contractor shall
contact the engineer to determine if adjustment con be
mode to correct the imbalance of earth.
