HomeMy WebLinkAboutPR 16816: CHANGE ORDER NO. 6 TO THE WASTEWATER TREATMENT PLANT REHAB PROJECT CONTRACT NO. 5 WITH ALLCO, INC. MEMORANDUM CITY OF PORT ARTHUR UTILITY OPERATIONS DEPARTMENT TO: Stephen Fitzgibbons, City Manager FROM: Kelly Eldridge, Director of Utility Operations /6i,/ - DATE: December 6, 2011 SUBJECT: Proposed Resolution No. 16816 RECOMMENDATION I recommend that the City Council approve Proposed Resolution No. 16816 authorizing the execution of Change Order No. 6 to the contract for the Wastewater Treatment Plant Rehabilitation Project, Contract No. 5, City Project No. 404WWT with ALLCO, Inc., of Beaumont, Texas, in the amount of $238,824.90, and increasing contract time by 120 days. BACKGROUND As a part of the Agreed Judgment between the City and the Texas Attorney General's Office/TCEQ Enforcement Division, we were required to have our WWTP's evaluated for deficiencies that have caused, or may cause, violations of our effluent permit. Item1: In the process of replacing equipment in Final Clarifier No. 403 at the Port Acres WWTP, it was determined that the Scum Collector Assembly was severly corroded and in need of replacement. The contractor has provided a replacement cost of $15,819.00. Item 2: During preparation for the installation of the new clarifier bridge in Primary Clarifier "A" at the Main WWTP, we found that the Center Pier support and rake assembly was badly bent and twisted beyond repair. This was the only item not already being replaced in this clarifier. Without replacement, total failure of the clarifier could occur at any time. The contractor has provided a cost of $223,820.00 for this item, along with a time extension request of 120 days. Item 3: While attempting to install an "Insta- valve" for the Sludge Thickener at the Main WWTP, the 50 -year old piping began splitting. We found about 50 feet of deteriorated pipe in need of replacement in order to complete the work, and did not have to use the expensive "insta- valve ". The extra piping costs $10,141.30. Item 4: This item deletes the " Insta- valve" at - $10,955.40. BUDGET /FISCAL EFFECT We have already committed all of our available ARRA grant funds on current projects. Therefore, we will utilize our existing bond funds that we allocated for this work before the grant became available. This Change Order adds 120 days to the contract time. STAFF /EMPLOYEE EFFECT City staff and our consulting engineer, Arceneaux & Gates, will continue to oversee this project. SUMMARY I recommend that the City Council approve Proposed Resolution No. 16816 authorizing the execution of Change Order No. 6 to the contract for the Wastewater Treatment Plant Rehabilitation Project, Contract No. 5, City Project No. 404WWT with ALLCO, Inc., of Beaumont, Texas, increasing the contract amount $238,824.90, and increasing contract time by 120 days.
