Home My WebLink AboutPR 16053: ALLCO, INC., CHANGE ORDER #3 MEMORANDUM CITY OF PORT ARTHUR UTILITY OPERATIONS DEPARTMENT TO: Stephen Fitzgibbons, City Manager FROM: Kelly Eldridge, Director of Utility Operations �C�c , DATE: September 1, 2010 SUBJECT: Proposed Resolution No. 16053 RECOMMENDATION I recommend that the City Council approve Proposed Resolution No. 16053 authorizing the execution of Change Order No. 3 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 $151,459. 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. The subsequent construction project is for the rehabilitation of deficiencies noted during this evaluation inspection of our Main and Port Acres WWTP's. During the award process, it became apparent that the bids were well above ARRA funding, so we deleted several Alternate Bid Items in an effort to get closer to our grant amount. Unfortunately, one of the associated items, the Main WWTP Sludge Thickener, has failed. Many of the minor repairs to the unit remained in the Base Bid, but we deleted an Alternate Bid Item that included some major items that also needed repairs, in hopes of getting funding from another grant source. The center drive mechanism has failed. It appears the 50 year old bearing housing has collapsed, causing the unit to lean and not operate. This unit is basically a 45 foot diameter concrete cylinder, with a conical bottom & center drain that operates by rotating rake arms that pull settled sludge to the center, while clarified water overflows the top and is directed to other treatment units. The center drive provides the rotation. With this unit out of service, we are in violation of out TCEQ permit, and there is no redundant unit. We are making arrangements to remove the rotating mechanism, the bridge to the center drive, and all rotating equipment from the basin in an effort to manually remove sludge from the unit without causing serious operational problems for the rest of the WWTP. Instead of performing the minor repairs included in the Base Bid, we have asked ALLCO, Inc. to provide pricing for replacement of the center pier, bridge, drive, scraper /skimmer, weirs, baffle, etc. The total provided by the contractor includes the new equipment, plus reprioritizes their work to get this unit back in order as soon as possible. That means they will have to make the emergency thickener tank modifications, remove all piping & equipment, and manually clean out our sludge holding lagoon, Allco will have to stop working on all other pay items to complete this priority item. Arceneaux & Gates Consulting Engineers has reviewed this proposal and recommends Change Order No. 3 to complete this work. While ALLCO has not asked for a time extension for this work, the change order includes a 41 day time extension for inclement weather since the start of the project. 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. 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. 16053 authorizing the execution of Change Order No. 3 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 $151,459, and contract time by 41 calendar days due to inclement weather P.R.

August 21, 2010 Mr. Hilly Patterson Alico, Inc. P. O. Box 3884 Beaumont, Texas 77704 Reference: City of Port Arthur, Texas - Main Plant Wastewater Treatment Plant Improvements Gravity Sludge Thickener Dear Billy: r We have had numerous conversations with Calvin Prosen and Enviroquip, Inc concerning the possibility of eliminating some of the scope of supply for the existing Gravity Sludge Thickener and thus reducing the cost of the Proposed Change Order for the Gravity Sludge Thickener., Calvin has pointed out to us that upon removal of the existing gravity sludge thickener mechanism, there are several components that may be reutilized in the final arrangement that would be acceptable to the Engineer and hopefully acceptable to the City of Port Arthur, Texas. We are please to propose the following for your consideration. 1. We will provide the following as new items, which shall be supplied as hop dip galvanized, and delivered to the jobsite. a, One New Access Bridge complete with galvanized steel grating and i aluminum handrails and drive platform to accept the new drive assembly provided in the base bid amount previously authorized in your Purchase Order No. 006162. I b. One New Center Pier to support the new drive gear arrangement. c, One New Drive Cage Assemb! for attachment to the new drive ear 9 Assembly gear arrangement and to rotate the sludge collections arms, d. Two New Sludge Collection Arms for attachment to the new drive cage I assembly. New Sludge Collection Arms to be complete with New Sludge Plows and Squeegees.

All New Required Fasteners, and Drill -In Anchor Bolts, for the items listed above (a thru d) plus the new drive assembly. 2. We will incorporate the following existing items into the proposed arrangement: a. The existing stainless steel influent well will be re- utilized and we will provide attachment to the New Access Bridge. (NOTE: The Influent Well does not rotate and is utilized to support one end of the side feed: arrangement Influent Feed Pipe.)' The existing Influent Well has a special fitting for the distribution of the side feed which will be re- utilized. b. The existing stainless steel ninety degree V -notch weirs will be re- utilized. (NOTE: These weirs are thicker than normal weir plates and sealing them against the existing reinforced concrete wall will be the responsibility of Allco, Inc.) c. The side feed Influent Pipe shall be the responsibility of AlIco, Inc., and shall not be provided by ETT. The side feed Influent Pipe must span between the existing wall pipe connection and the inlet connection on the existing influent feed well. (NOTE: The existing side inlet influent feed' pipe may be approved for re- utilization by the Engineer and the City of Port Arthur.) The net cost reduction for re- utilizing the existing items mentioned above is $ 35,000.00. To keep this paperwork as simple as possible, we proposed to delete the cost reduction shown' above completely from the original ADDER AMOUNT OF $ 155,990.00, Thus the new REVISED ADDER AMOUNT WOULD BE $ 120,990.00, The net cost to Allco, Inc., would be the same, although the savings are technically attributable to the Base Bid Item, Ve truly yours, ( 3 0.
