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 will repair the damages experienced from the flooding, as
well as move 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 must 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 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 the original contract.
Quantity Adjustment/Change Order No. 1 adjusted Bid Item quantities 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 increased the contract to $4,173,378.72.
Quantity Adjustment/Change Order No. 2 is needed to finalize Bid Item quantities for modifications
to Air Compressor panel to match incoming power. The bid item adjustment and change orders will
increase the contract to $4,175,118.72.
Staff recommends approval.
