FROM: BRUNO RUMBELOW, CITY MANAGE
MEETING DATE: JANUARY 7, 2014
SUBJECT: DFW CONNECTOR MASTER UTILITY ADJUSTMENT
AGREEMENT FINAL COST AND PAYMENT - SH 114/121
RECOMMENDATION
City Council consider approving an adjustment to the final cost of the DFW Connecter
Master Utility Adjustment Agreement with NorthGate Constructors to $1,868,850.41 for the
necessary relocation and adjustment of City water and wastewater facilities in the DFW
Connector Corridor of SH 114 and SH 121, authorizing City Manager to issue final
payment in the amount of $47,948.85, and take any necessary action.
FUNDING SOURCE:
Funds are available in Utility Accounts 200 - 48930- 534 -8- 000005 WA and 200 -48940 -534
8- 000005 SW.
The construction of the DFW Connector project necessitated the relocation and adjustment
of City water and wastewater facilities throughout the corridor. These relocations and
adjustments were performed under a Master Utility Agreement with NorthGate
Constructors approved by City Council on March 16, 2010.
The Master Agreement stipulated the general terms and guidelines under which the City
and NorthGate Constructors pursued our relocations.
In this Master Agreement process, the City Council approved a cost estimate for the
relocations based on bid prices and the most up to date quantities available. The staff
would then approve supplemental agreements, UAAA's, addressing specific components
of the project scope with more refined quantities as the final plans were developed in this
fast paced design and construction process. Changes to the total cost estimate would be
submitted to the City Council if the cumulative cost of the UAAA's exceeded the agreement
estimate of $1,819,646.80 price plus a $15,000.00 contingency.
The cost of the project with the final payment estimate of $47,948.85 totals $1,868,850.41.
This increase to the project exceeds the agreement estimate plus staff's change order
authority of $15,000.00 and requires City Council approval.

The difference between the project estimate and the final project cost, $49,203.61,
represents a 2.7% increase to the project which is exceptional considering the fact that the
initial project estimate was prepared before most of the utility adjustments were designed
as the project progressed under the design /build concept.
Staff recommends approval.
