Title
Consider a resolution authorizing the Mayor to execute Quantity Adjustment/Change Order No. 1 with T. Gray Utility & Rehab Co., LLC for the 2016 Wastewater Collection System Rehabilitation - Manhole Rehabilitation, Open Cut, and Point Repairs Project.
Body
The City is required to continue our Wastewater Collection System Rehabilitation program in order to comply with the Texas Commission on Environmental Quality's (TCEQ) Edwards Aquifer Recharge Zone Protection Program which 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 has completed the inspection of 12 sub-basins to determine areas that require rehabilitation for this project.
The work being performed under this contract includes sub-basins BC-01, BC20-Z, CC32-Z, CC34-Z, CC35-Z, CC37-Z, LC09-Z, LC15-Z, LC16-Z, LC17-Z, LC18-Z & LC19-Z. The project includes 2,450 LF of new 8-inch through 10-inch pipe installed by pipe bursting, 2,650 LF of 8-inch through 42-inch CIPP liner, and construction of six manholes.
T. Gray Utility Company was awarded this contract in the amount of $1,362,800.00.
Quantity Adjustment/Change Order No. 1 (QA/CO No. 1) is needed for change order items and includes a 30-day contract time adjustment due to unforeseen items during construction. The additional work required by the contractor included rehabilitation of five existing wastewater manholes along Dell Way. QA/CO No. 1 is for $57,950.00 which brings the total construction contract to $1,420,750.00.
Cost: $57,950
