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.

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. r Da A. Hawkins, P.E. Director of Water Utilities
