Analysis
On March 4, 2014 the City awarded a construction contract to Texas Standard Construction in the total amount of $704,507.90 for Fargo Outfall Rehab Project. Included as part of the contract award was a 5 percent contingency of $35,225.39 for project changes while under construction, which is typical for Capital Improvements projects.
This project was originally driven by the 2008 Grand Prairie Wastewater Master Plan, identifying it as a need to alleviate periodic sanitary sewer overflows during wet weather periods. This project was selected by the Texas Water Development Board as a project eligible for a Green Project Reserve Grant, equating to $87,000 towards the construction cost being provided to the City by the State. TWDB approved the award and issuance of a notice to proceed for this project which consists of the rehabilitation and replacement of 3,525 linear feet of wastewater pipelines west of FM 1382, south of Fargo Drive with initial project completion in early 2015.
This final reconciliation change order/amendment No. 5 provides for by-pass pumping mobilization, setup and demobilization and teardown. It also provides for quantity under-runs due to deletion of the rehabilitation portions of this project. The upstream portions of the pipe replacement by the cured in place method could not be performed due to continuous heavy surcharges from TRA lines downstream from the City’s system. It was anticipated that TRA would complete the rehabilitation of their system by early 2016. However, due to TRA project delays and timing uncertainties, City staff recommends awaiting completion of TRA downstream improvements before re-advertisement for construction contract to complete this project.
Financial Consideration

No additional funding is requested for this change order, however, the funding source for this project is in the Waste Water Capital Projects Fund (500692), WO #01211803 (Fargo Outfall Rehab).
