CHANGE ORDER No. 1
PROJECT:
Aquifer Study for Kimberly-Clark Wellfield Project
ENGINEER:
Parsons Engineering Science, Inc.
Original Contract Cost: $51,374.00
Total WQrk Completed: $68,541,17
Amount of Change Order: $17,167.17
The above additional charges where incurred due to several
factors listed below.
* Modeling the effects of the well field took more effort than
anticipated, due to the large size of the modeled area. The
Engineer's estimate was for a model about one half the size
actually required to simulate the proposed 15 MGD wellfield,
* The GA GGS requirements developed in November 94 for well-
head protection were not available when the job was
originally proposed; The Engineers were required to develop
a discussion of the County's plan to meet these requirements
with the wellfield permit application,
* The County requested a few additional services, including
submission of a permit application for the existing well.
Attached as part of this change order are correspondences from the
Engineer explaining the incurred overruns,

Subject: Budget and Schedule Status for KC Wellfield Project
Dear Mr. McElveen:
As you know we are nearing the end of the subject project and we need to alert you
that the project cannot be completed by Parsons Engineering Science (parsons) within
the original budget estimate. To date we have incurred the following costs compared to
earlier cost estimates (originally prepared May 1994 and revised Jan. 1995):

From this table you can determine that we are already over the authorized budget.
and we have not completed the permit application for the new wellfield. As indicated.
we now estimate we will need a budget ceiling of $67.745 to complete the project. There
are several factors that led to this situation. including:
. Modeling the effects of the well field took more effort than anticipated. due to
the large size of the modeled area. Our estimate was for a model about 1/2 the
size actually required to simulate the proposed 15 MGD wellfield.
. The GA GGS requirements developed in November 94 for well-head protection
were not available when the job was originally proposed; Parsons must develop

a discussion of the County's plan to meet these requirements with the wellfield
permit application.
. The County has requested a few additional services, including submission of a
permit application for the existing well.
Overall, we believe the work has progressed well and that the GA EPD will approve
the permit once submitted. Regarding the schedule, we suggest that you consider the end
of June as urget completion date. We have yet to hear from Mr. Serefli, or any GA GGS
employee, to setup a meeting to discuss our modeling report and the potential effects of
the new wellfield.
Please call Craig Sprinkle at 404/235-2370 if you wish to discuss this request for
additional funding. We will need to get your approval for the budget increase before
continuing to work on the permit application.
Sincerely,
PARSONS ENGINEERING SCIENCE, INC.

Subject:
Documentation of Job Charges - KC Wellfield Project
Dear Mr. Dillard:
Per your request today I am writing to explain the charges incurred by Parsons
Engineering Science (Parsons) and billed to the County for the subject project. As you
know our total billings of $68,541.17 exceeded our cost estimate to complete the project.
Based on assumptions contained in our letter to Mr. McElveen dated May 17, 1995,
Parsons estimated a total cost at completion of $67,745. As the work actually developed,
Parsons was not able to complete the project as soon as planned; the DNR personnel
were not available for a required meeting until August. Following the August meeting
with the DNR, Parsons prepared a second wellfield permit application for submittal to
the GA DNR. The extension of the project and the extra permit application accounts for
the $796.17 that we billed the County above the $67,745 requested in May 1995.
I hope this letter helps explain our invoices. I apologize that I have not answered
your questions earlier. If you have additional questions or concerns, please call me at
404/235-2370. Thanks for helping me close out this project!!
Sincerely,
PARSONS ENGINEERING SCIENCE, INe.
