Passed by the City Council this 13 th ATTEST: Betty . Johnso , City Secretary APPROVED AS TO CONTENT: Terry Ellerbrook, Managing Director of Water Utilities APPROVED AS TO FORM: Ueftld G. Va City Attorney dp: ccdocs/co-water.res March 29, 1995 LUBBOCK, TEXAS SOUTHEAST WATER RECLAMATION PLANT IMPROVEMENTS CONTRACT 4 - WATER RECLAMATION PLANTS 2 & 3, LABORATORY IMPROVEMENTS AND DEMOLITION OF PLANT 1 CHANGE ORDER NO. 6 SCOPE. This Change Order No. 6 covers the following change to the Contract Documents: Add lump sum for modification of effluent pumps EP-804 and 805 to increase the performance capacity of the pumps. REASONS FOR CHANGE: A lump sum add is included for modification of effluent pumps EP-804 and 805, along with associated motors and variable speed drives, to increase the performance capacity of the pumping units. The performance capacities of EP-804 and 805 require modification to allow pumping of effluent water to Southwestern Public Service (SPS) at a higher flow rate than anticipated at the time of design. In addition to the higher flow rates, the length of discharge piping to SPS was considerably longer than information at the time of design indicated. The increased flow rate and longer discharge pipeline necessitates the increase in performance characteristics of the pumping units. SPS has a contract with the City which pays the City for the effluent water that SPS receives. The increased flow rate required by SPS will result in a substantial increase in revenues received from SPS. Attached to this Change Order is a copy of Black & Veatch letters CP-15 and CP-15A, along with a cost breakdown from BRB Contractor-s Inc. for the work performed. BASIS FOR CHANGE: Modify effluent pumps EP-804 and 805, including motors and variable speed drives, to increase performance characteristics of the pumps for a lump sum cost of $84,599.68. (LUBBOCK, TEXAS ) (17578.440 ) (CHANGE ORDER NO. 6) C06-1 CHANGE TO CONTRACT PRICE.
