Re: Terminal Storage Reservoir Rehabilitation
Dear Sir:
Enclosed are recaps of Change Order Proposals No. 1, 3, 4, and 5.
Please note on Change Order Proposal No. 5, no removal or
replacement of liner was done at the Southeast corner of the
reservoir. However, we were required to make several repairs as
directed by the Owner's representative. We use this CPR to show
those additional repairs. Please issue a change order in the
amount of $20,843.20, along with an additional forty days. This
encompasses the four enclosed Change Order Proposals, along with
Change Order Proposal No. 6 and our letter of March 5, 1993 to Ron
Shuffield with the City of Lubbock. The recap of this Change Order
cost is as follows:
CPR Cost
1 - Northeast Corner Repairs $10,943.75
2 - Liner Installation Change 0.00
3 - Northeast Corner Line Replacement 3,175.20
4 - Southwest Corner Repairs 2,702.00
5 - Other Line Repairs 1,007.75
6 - Liner Vents 3,014.50
TOTAL CHANGE ORDER: $20,843.20
Should you have any questions concerning this, please feel free to
contact us. We will be submitting our current month Is Pay Estimate
with all work shown as complete and request that retainage be
reduced to 10. Including this Change Order, that would leave the
City roughly 33,000.00 to take care of any problems which might
arise concerning seeding. Once this change order has been
approved, we will submit our final Pay Estimate.
Thank you,
RED RIVER CONSTRUCTION COMPANY, INC.

MEMO
TO: Bob Cass, Interim City Manager
FROM: Dan A. Hawkins, P.E., Director of Water Utilities
SUBJECT: Agenda Items and Comments for City Council Meeting
for May 27, 1993
DATE: May 17, 1993
VI. WATER UTILITIES
ITEM #/SUBJECT
Consider a resolution authorizing the Mayor to execute a Change Order
agreement with Red River Construction Co. for necessary additional work
for the City of Lubbock Water Treatment Plant Improvements, Terminal
Storage Reservoir Rehabilitation.
BACKGROUND/DISCUSSION
Initial Contract amount for construction of this project is
$1,247,750.00. The scope of this rehabilitation project was to remove
badly damaged liner, repair and rework interior embankments and replace
damaged liner with approximately 30,000 square yards of concrete.
In the course of this project it was necessary to perform additional work
that was unforeseen due to the fact that this work was not obvious until
the existing liner was removed and deterio- rated slopes were revealed.
The majority of the additional work performed was in the corner sections
where the damage was the most severe (see attached letter with break down
of Change Order Costs).
SUMMARY/RECOMMENDATIONS:
Due to the nature of this project and the need to have a sound and solid
terminal storage reservoir for the water treatment plant operation it is
our recommendation to accept the Change order of $20,843.20 as presented
by HDR, engineering consultant for this project, and Red River
Construction resulting in a total cost of construction of $1,268,593.20
which would be approximately 1.7% over the original contract amount. The
Council budgeted $1,800.000 in FY 92-93 for this work, providing a large
contingency fund primarily t llow for such unknown conditions.
