Re Additional Services
Lake Ray Roberts

and Off-Site Facilities
Dear Mr Ham
As you know, Freese and Nichols estimated that a budget of approximately
$65,000 should be considered for additional services on the above
referenced project These funds were to be used as necessary for such
items as surveying, water quality testing and additional meetings beyond
those required in basic services The City has requested that we refine
our additional services budget now that we are underway on the assignment
At the present time we estimate fees for additional services would be as
follows
Off-site facilities
A Surveying and easements

and City Boards

Attached please find a proposal from James M Mont3omery for Iterrt IIB and a
letter from Coleman and Associates for Item IIA
It would be desirable to budget slightly more than $32,100 It is ray
recommendation that the City establish a budget of not-to-exceed $35,000
for additional services We will advise the City it appears that
additional funding would be necessary on this project If this proposal is
acceptable to the City, please authorize us to proceed by signing the extra

Re Surveying Services Denton Water Project
Dear Mr Veach
At your request we have compiled some information concerning the above-
referenced project Comparing this project to other, similar projects we
have knowledge of in this area, we submit the following surveying cost
estimates
MAIN PUMP STATION SITE PRE-DESIGN TOPO
Field surveying for topographical information sufficient to develop
1 (one) foot contours with detail of easements, etc Note reduc-
tion, plotting, and drafting to prepare detailed map of 76 acre Main
Pump Station site
Approximate Coat $7500
It has been our experience that a FEE ESTIMATE with a well-defined scope-
of-project is the most equitable method of billing You would be invoiced
regularly for work-to-date at an hourly rate This arrangement allows
greater flexibility of both scope and scheduling during the course of the
project
I trust this information will be of some value to you Keep in mind that
these are only general estimates based on some similar projects If you
have any questions or require additional information, please don't
hesitate to call as

Please include the following information in agenda item for New Water
Treatment Plant and Off-site Facilities Additional Services
Freese & Nichols has now completed their preliminary review of Lake Ray
Roberts Water Treatment Plant and Off-site Facilities As indicated in
their attached letter dated May 25, 1988, additional services are now
required that were not included in the basic services portion of the
original contract
The additional services include surveying of construction sites,
additional meetings and water quality testing that could not have been
accurately estimated in the preliminary review stage These services
are more clearly defined as follows
1 Because pro3ect sites have now been determined, accurate estimates
can now be obtained for surveying
2 Additional public meetings are needed now that the project scope is
more clearly defined
3 Under basic services in the original water treatment plant
contract, dated February 16, 1988, Lake Ray Roberts water was
sampled and analyzed The initial analysis revealed additional
water quality testing needs to be performed in order to meet the
Safe Drinking Water Act Amendments of 1986

MEMORANDUM
TO R E Nelson, Executive Director, Department of Utilities
FROM C David Ham, Director, Water/Wastewater Utilities
DATE June 30, 1988
SUBJ Additional Engineering Services - Lk Ray Roberts Water Plant
When the basic engineering contract for services with Freese and
Nichols, Inc was approved by City Council on February 16, 1988, the
new water plant and booster pump sites had not been firmly located nor
had the quality of Lake Ray Roberts raw water been firmly established
with regards to new Environmental Protection Agency and Texas Depart-
ment of Health regulations
Freese $ Nichols, Inc had mentioned to the Utilities Staff that
additional services in the amount of $ 68,000 might be required after
these sites were firmly located for topographic surveys, planning and
zoning, City Council briefings and additional water quality testing
The utilities staff considered waiting to request these additional
services until the sites were firmly established and after a meeting
in Austin with the Texas Department of Health Freese & Nichols has
reduced their original estimate to $ 32,100 with a maximum not to exceed
$ 35,000
It is paramount that the City Council approve these additional services
for the project to proceed forward
