Re: Proposal for Geotechnical Engineering Services
Raw Water Pumping Station
Augusta-Richmond County, Georgia
OQRE Proposal No. 84-1236R
-;
OORE Property Sciences (OORE) is pleased to present this revised proposal for providing geotechnical
engineering services for the referenced project.
1.0 PROJECT DESCRIPTION
Based on information provided by CH2M Hill on October 31,2001, the proposed structures will be various
piping, pumps, turbines, channels and an outfall for a pumping/turbine facility located between the
Augusta Canal and the Savannah River in Augusta, Georgia. The Zimmerman, Evans and Leopold, Inc.
(ZEL Engineers) drawing dated August, 2001 does not provide all finished elevations for the planned
structures, therefore, we assume those not indicated will be as close to existing grades as possible.
OORE representatives made site visits on 'November 6 & 8,2001..
The area for location of the turbines and generators appears to be constructed of fill containing rubble,
rocks and possibly boulders. Drilling through thi;5 material is very difficult and may require a combination
of power auger and rock core drilling.
2.0 SCOPE OF SERVICES
2.1 Geotechnical Exploration
The scope of work includes 43 borings in accordance with applicable ASTM Standards, as shown on the
ZEL Engineers drawing referenced in paragraph 1 above. The borings will be carried 5 feet into rock by
coring, or to elevation 120, whichever is encountered first. Based on the boring locations, and existing
ground elevations, we estimate up to 1000 feet of soil test borings and possibly 215 feet of rock coring
may be required.

Paqe 2
Our services include backfilling the borings located within the canal embankment, with cement grout or
bentonite pellets. Other borings will be backfilled with auger cuttings. .
After completion of ' the field work, we will perform the necessary laboratory testing and analyses to
provide the recommendations and discussion outlined below.
2.2 Report and Recommendations .
We will provide the following recommendations and report:
. Foundation design parameters, including types, depths, allowable bearing capacities, and
estimated settlements
. Parameters for design of-retaining wall(s), including lateral earth 'pressures
. Earthwork, including site and subgrade preparation, fill placement, excavation
conditions, and suitability of existing soils for fill materials
. Slabs-on-grade .
. Depths to rock and rock characteristics
. Groundwater levels
. Final report signed by a Professional Engineer registered in the State of Georgia with
the above recommendations, a description of subsurface conditions, soil test boring
logs, laboratory test reports, and a boring location plan.
2.4 Site Clearing
The site is heavily wooded; therefore considerable clearing of brush and some small trees will be
necessary to access the boring locations. We have included the cost for this clearing in our proposal.
Some of the proposed site appears to be used for disposal of debris from bar screens. Our cost does
not include moving these piles of debris for access to horings.
;'\
3.0 SCHEDULE,
Typically, a drill rig can be mobilized to a site within two weeks after notice to proceed has been given.
We estimate that 12 work days will be required for the field exploration. Verbal results will be transmitted
to your office within 2 to 3 days after completion of the subsurface exploration, and a formal report will
follow in approximately 3 weeks. The proceeding describes a typical schedule and it can be modified to
meet your particular needs.
4.0 ASSUMPTIONS
We assume that the client will obtain right-of-entry into the site for our drilling equipment and personnel.
The moving of drilling equipment around a site and drilling soil borings will leave some areas disturbed.
While we will try to limit site disturbance, our fee does not include re-Iandscaping or otherwise restoring
the site to its original condition. Over time, some settlement of boring backfill may occur. SU/l(eying of
the boring locations will be performed by others, and is not included in our scope of work.
