PURPOSE:
Water Resources is requesting a contract change order to the T. Z. Osborne Water Reclamation Facility (WRF) Package 2 Contract 2011-038A in order to construct filter and chlorine contact chamber piping modifications resulting from value engineering efforts tied to the T.Z.

In order to provide the required infrastructure and meet construction contract timelines specified for package 3, approval for a contract change order is requested.
