In July of 2014, the City Council approved a construction contract with Prota Construction, Inc. for
the Chandler Creek 1 - Upper Phase Wastewater Line Project in the amount of $1,301,969.
The Chandler Creek 1 - Wastewater Interceptor consists of three phases. The first phase was built
with the Legends Village Section 2 -Phase 4 subdivision and was oversized with participation by
Round Rock to ensure adequate capacity to accommodate future growth to the north. The second
phase, CC - 1 L, was recently completed and tied the Legends Village portion south to the existing
Chandler Creek Wastewater Interceptor.
This third phase, Chandler Creek i- Upper Phase (CC -1 U) Wastewater Line includes 6,800 Linear
Feet of 18 inch wastewater line and necessary appurtenances and will provide peak flow wastewater
capacity for the Avery Centre East and south, the Round Rock ISD property at the northeast corner
of Old Settlers Blvd. and A.W. Grimes Boulevard, and the area north of Legends Village and tie into
the existing wastewater infrastructure.
Only Phase I of the project will be constructed at this time. Phase II will be deleted from the contract
until which time development north of Old Settlers Blvd. is in place and will require service via Phase
II construction of the project. One additional manhole will be added to the north end of Phase I
construction to increase the wastewater line deflection angle and make for smoother flow.
This Quantity Adjustment/Change Order No. 1 will lower the contract amount from $1,301,969 to
$1,005,354.
