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.

Change Order/Quantity
Adjustment No. 1
Change Order No. 1 is need to perform repairs to an 8" wastewater main along Mays Street beginning near Brushy Creek then northward
approximately 900 L.F., and to delete bid items no longer required. A time extension to the original contract is needed for the repairs and due to
redesign of plans due to field verifications and delay in installing 8" wastewater main reroute south of Logan Street along S. Mays. Delays along
S. Mays were due to utility relocations and City obtaining ownership of S. Mays.
