Title
Consider a resolution authorizing the Mayor to execute Quantity Adjustment/Change Order No. 1 with T. Gray Utility & Rehab Co. for the Basin 2 and 3, Cycle 3 Manhole Rehabilitation Project.
Body
The City is required to continue our Wastewater Collection System Rehabilitation program to comply with the Texas Commission on Environmental Quality's Edwards Aquifer Recharge Zone Protection Program. This program requires that wastewater collection systems located over the Edwards Aquifer be inspected and rehabilitated every five years. The elimination of defects will not only help to protect the Edwards Aquifer, but will also reduce inflow and infiltration entering the City's wastewater collection system, thereby reducing the City's treatment cost. The City had completed the inspection of 12 sub-basins to determine areas that required rehabilitation for this project.
This construction contract with T. Gray Utility Company is for the rehabilitation of 180 manholes located in these sub-basins. The original contract amount was for $399,503.
During the construction of this project, more detailed inspections determined certain work could be removed from the contract. The contractor and the City worked together based on the contractor’s field inspections to determine the exact repairs necessary. Based on the field information, this Change Order No. 1 is to deduct the quantity of work from this contract by $154,293.06, bringing the contract sum to $245,209.94.
Cost: -$154,293.06
