Type: City Manager Item Governing Body: City Manager Approval Agenda Date: 7/5/2013 Dept Director: Michael Thane, Director of Utilities and Environmental Services Cost: $45,873.00 Indexes: Self -Financed Wastewater Construction Attachments: Quantity Adjustment -Change Order 1 - Revised Text of Legislative File CM -13-07-099 The City is required to continue this program in order to comply with the Texas Commission on Environmental Quality (TCEQ) Edwards Aquifer Recharge Zone Protection Program. This Program requires wastewater collection systems, located over the Edwards Aquifer, to be inspected and rehabilitated every five years. The elimination of defects will help protect the Edwards Aquifer, as well as reduce inflow and infiltration entering the City's wastewater collection system, thereby reducing the City's treatment cost. On August 23, 2012, City Council awarded a contract to RePipe Construction, LLC in the amount of $1,536,866.40 to perform necessary repairs and improvements to rehabilitate the wastewater collection system in nine sub -basins (BC20-Z, CC32-Z, CC34-Z, CC35-Z, CC36-Z, CC37-Z, 0C24 -Z, 0C25 -Z and 0C26 -Z). Additional repairs to the wastewater collection system have been identified along Mays Street near Brushy Creek and northward approximately 900 linear feet. The repairs consist of replacement of an 8" wastewater main, and the removal and installation of new manholes. The cost of these additional repairs after deducting originally bid line items that are not necessary adds $45,873 to the original contract and adds 90 days to the contract time. This Change Order No. 1 brings the original contract amount of $1,536,866.40 to a new contract amount of $1,582,739.40. Staff recommends approval.
