MEMORANDUM
TO: RODNEY J. RAY
CITY MANAGER
FROM: F. ROBERT CARR, JR., P.E.
PUBLIC WORKS DIRECTOR Z �0�
SUBJECT: AMENDMENT TO ENGINEERING DESIGN SERVICES CONTRACT -
WASTEWATER TREATMENT PLANT PHASE I IMPROVEMENTS
DATE: March 13, 1996
BACKGROUND:
On May 16, 1995, the Trustees awarded a contract to FHC, Inc. to perform engineering design
services for Wastewater Treatment Plant improvements. The scope of work and the fee proposal
for the project was divided into three (3) work phases as follows:
Preliminary Design $84,400
Final Design 64,400
Bidding 9,000
Total Lump Sum $157,800
ORIGINAL PROJECT SCOPE:
The existing City of Owasso wastewater treatment facility was constructed in 1986. The plant
consists primarily of an oxidation ditch with interchannel boat clarifier, effluent ultraviolet light
disinfection and reaeration, and sludge drying beds. The plant was originally designed to treat
an average daily flow of 1.56 million gallons per day (MGD).
With the current average daily flow approaching the original design capacity and new effluent
limitations that require increasing the treatment capabilities of the existing plant, an amendment
to the Facilities Plan was completed in order to obtain funding through the State Revolving Fund
(SRF) loan program to include the needed modifications. The document has received approval
from the Oklahoma Water Resources Board.
The approved Facilities Plan serves as the mechanism for selection of the most cost - effective
treatment system for the 20 -year planning period. The document is the basis for detailed
engineering design and ultimate construction of the needed improvements.

Amendment to Agreement for Engineering Services
Oxidation Ditch:
' The existing building used to house chlorine for oxidation ditch bacteria control is located
adjacent to the ditch. The improvements designed addition of chlorine at another location
that would enable easier handling of the chlorine cylinders. Relocation of the building
was proposed by staff and was included in the design work with compensation.
The south end of the oxidation ditch presently is covered with a redwood decking to
control splash from the aerator. The decking is extremely difficult to keep clean of
algae. Staff desired to have the deck replaced with a solid material that would keep the
splash below the deck. Additionally, a manhole near the aerator was requested to enable
operators access to more safely tighten the aerator bolts was requested. Additional
compensation of $1,900 was requested for this item.
A summary of the additional items is as follows:
Relocate Control Building (Influent Lift Station area) $2,900
Headworks 1,000
Oxidation Ditch 1.900
Total additional services $5,800
Staff requested FHC to provide documentation of the use of the original design hours. It was
felt that it would be difficult to recommend additional compensation without knowing what level
of effort had been spend on the original scope of work. A summary of the original manhour
budget versus actual hours is presented below:

FHC has legitimate reasons to request the additional compensation detailed above.

THIS AMENDMENT NO. 1 made and entered into this day of
, by and between Owasso Public Works Authority,

WHEREAS, Engineer is prepared to provide said additional services;
NOW THEREFORE, Engineer and Owner agree to amend certain items of the original
Agreement as follows:
Add to the end of Attachment A, Scope of Services:
III. ADDITIONAL IMPROVEMENTS
The following items of additional work shall be included into the final design.
A. Relocate Control Building (Influent Lift Station Area). Relocate the
existing influent lift station control building to an elevation above the flow
equalization pond maximum water surface. Raise wet well and the valve
vault walls to the same elevation. Relocate the fuel tank to above ground
adjacent to the generator.
B. Headworks. Remove existing mechanical bar rack and install a grinder
( "channel monster ").
C. Oxidation Ditch Deck. Replace the existing redwood deck and install an
access opening.

RE: Opinion of Probable Construction Costs
Parefiminary Design - 30 % Design Memorandum Submittal
Wastewater Treatment Plant Please I Improvements
Dear Mr. Carr:
Please find enclosed a cop y of the opinion of probable construction costs for your review and
comments.
Items 1 through 9 correspond to the original scope of services. The estimated construction cast
for these items is approximately $2,211,530 and the estimated total project cost is approximately
$3,069,604. The cost estimates included in the amendment to the facility plan for the
construction cost and total project cost are $1,950,000 and $2,781,500, respectively. However,
it is noted that these are 1994 costs, and when adjusted for escalation at 4.0% annually to 1996,
they equal $2,109,120 and $3,011,715, respectively. Further, the current cost estimate also
includes O&M Manual preparation and Project Certification which were not originally included.
These items may be needed per SRF guidelines.
Item 10 pertains to various items of work requested by the City since the project started. The
total estimated construction cost and project cost for these items are $253,755 and $335,718,
respectively. Most of these items can be included in the design without affecting the design
compensation and schedule; however, there are a few items that would require additional efforts
as described below.
Relocate Control Building (Influent Lift Station Area). This item will require additional
survey and design efforts as well as development of new drawings. Estimated additional
engineering compensation including survey is $2,900.
