Home My WebLink AboutPR 16812: CHANGE ORDER NO. 6 TO CONTRACT WITH ALLCO, INC. FOR SANITARY SEWER REHAB BY THE PIPE BURSTING AND SLIPLINING METHODS PROJECT MEMORANDUM CITY OF PORT ARTHUR UTILITY OPERATIONS DEPARTMENT TO: Stephen Fitzgibbons, City Manager FROM: Kelly Eldridge, Director of Utility Operations DATE: December 5, 2011 SUBJECT: Proposed Resolution No. 16812 RECOMMENDATION I recommend that the City Council approve Proposed Resolution No. 16812 authorizing the execution of Change Order No. 6 to the contract between the City and ALLCO, Inc., of Beaumont, Texas, increasing the contract amount by $95,534.44, for the Sanitary Sewer Rehabilitation by the Pipe Bursting and Sliplining Methods, Basins PA64C & PA66, Contract No. 6, City Project No. 404PB6. BACKGROUND This project was for the cleaning, television inspection, and rehabilitation of approximately 83,000 feet of sanitary sewer mains, plus the replacement of every service connection served by these main lines in the Port Acres area. The original project scope included the inspection of all lines that used older - technology pipe material, with an estimate of having to replace /rehabilitate about 80% of those lines. Change Order No. 6 addresses three separate items. The first item deals with the replacement of a 60" drop manhole on the 30" diameter gravity sewer along WPA Road near the DD #7 Pump Station. In the course of performing line repairs and manhole rehabilitation under Changer Order No. 4, the contractor discovered what we had thought to be a line cave -in to actually be a catastrophic drop manhole failure. Drop MH's are used where at major elevation changes in the flow lines of the incoming and outgoing sewer lines. This failure was considered a safety hazard due to its proximity to the adjacent highway and railroad tracks, and had to completed ASAP. Railroad and TXDOT personnel were on site to observe the extent of repairs. The second item is due to the alignment of the sanitary sewer line along a section of 61 S' Street. The gravity sewer line along 61' St. is generally in the shoulder of the roadside ditch. However, a 138 foot section juts out into the pavement, apparently in an effort to avoid other very close infrastructure in the immediate area. This will force the contractor to remove & replace this short, but deep section under pavement. The last item simply restores some previously deleted manhole rehabilitation work. A previous changer order deleted more than originally thought. BUDGET/FISCAL EFFECT Change Order No. 6 increases the contract amount by $95,534.44. Note that we are already over the grant amount, so these funds will have to come out of the City Sewer Bond Fund. STAFF/EMPLOYEE EFFECT None.
