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 the City 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 1- Upper Phase (CC -1 U) Wastewater Line includes 6,800 Linear Feet of
18 -inch wastewater line and necessary appurtenances and will provide peak wastewater
flow capacity for the Avery Centre east and south, including the area north of Legends
Village and tie into the existing wastewater infrastructure.
Because of a change in Atmos Energy's policies that took place after discussions held
during the design phase, it was necessary to "jack and bore" beneath the Atmos high
pressure gas lines. Quantity Adjustment/Change Order (QA/CO) No. 1, executed in
September of 2014, lowered the contract amount from $1,301,969 to $1,005,354. QA/CO
No. 2 will increase the contract amount to $1,025,354.
Staff recommends approval.
