On September 7 & 8, 2010, Brushy Creek experienced extraordinary flooding conditions that caused
the creek level to swell out of its banks and inundate a portion of the Brushy Creek Regional
Wastewater System (BCRWWS) - West Wastewater Treatment Plant. Since that time, the facility
has been shut down, and the wastewater flow has been diverted to the BCRWWS - East
Wastewater Treatment Plant. This project has repaired the damages experienced from the flooding,
as well as moved equipment that was previously located in the floodplain to a higher elevation. In
addition, under a renewed wastewater permit as of September 28, 2012, the plant can now achieve
all of its plant effluent discharge parameters, including an additional 17.4 mg/I daily average for
nitrate nitrogen.
On November 13, 2012, four bids were submitted. Archer Western Construction, LLC was the low
bidder with a bid of $4,172,400. The Cities of Cedar Park, Austin, and Round Rock have paid for this
rehabilitation project based on their allocated capacity in the treatment system. The City of Cedar
Park percentage of capacity is 14.61% or $609,587.64; the City of Austin percentage of capacity is
3.43% or $143,113.32; and the City of Round Rock percentage of capacity is 81.96% which is
$3,419,699.04 of this contract.
Quantity Adjustment/Change Order No. 1 is needed to adjust Bid Item quantities and for
modifications to Basin #2 Airlift piping, Roof Hatch enlargement, and addition to contract time by 41
calendar days. The bid item adjustments and change orders will increase the contract to
$4,173,378.72.
Staff recommends approval.
