Analysis
This work will allow future emergency water line interconnect between Grand Prairie and Mansfield. Due to adjacent Development, it is necessary to change the original plan and scope of work. The proposal includes a $31,700 reduction in materials and an addition of $44,925 in materials. Since this is a betterment over the existing situation (there is currently no provision for an interconnection), this is not a reimbursable item.
Several years ago when we had to shut down our 60" water line supply line from Dallas, we took water from Mansfield near this location by connecting fire hydrant hoses. This item will provide pipelines that will, when completed in the future, provide greater volume of water exchange in the event of a future similar event. Because of the pressure differential between Mansfield and Grand Prairie Water Systems at this location, the water flow would be unidirectional from Mansfield to Grand Prairie, providing no benefit to Mansfield.

Funding for change order No 2 in the amount of $13,225 is available in the Water Capital Projects Fund (500592) WO #01710403 (S H 360 Utility Relocations I20/287).
