Staff is requesting that the City Council consider authorizing and executing a Contract Amendment for Professional Services with HDR Engineering for W.O. 10-29 WWTP West Mechanical Motor Control Centers (MCC) Replacement and Improvements at the Wastewater Treatment Plant.  Due to the complexity of the sequencing/demolition of the existing motor control centers (MCCs) and installation of the new MCCs, additional construction services are needed for the project. Because of the critical nature of these MCCs for the treatment process, additional effort is required to determine how and when equipment can be taken off-line and what equipment is needed to stay on-line to meet wastewater plant needs. For previous MCC replacements, the new MCCs could be installed in a new location and loads moved over one by one. Due to space limitations in the West Mechanical Room, the MCCs need to be replaced one at a time in the same location. Also on previous MCC replacements, daily construction observation was not needed. Again, because of the complexity, daily meetings are required with the contractor, engineer and plant staff so that everyone knows what equipment will be available that day.

The Council may:

•  Authorize Contract Amendment No. 2 with HDR Engineering in the amount of $10,900; or
•  Do not authorize the Contract Amendment No. 2. If the contract amendment is not approved, the consultant will not be able to perform construction observation for the full duration of the project.

Funds for this Contract Amendment No.2 are available from Wastewater Funds budgeted in FY13. If approved, the Professional Services Contract with HDR Engineering will total $70,000.00.

Staff recommends that Council authorize Contract Amendment No. 2 with HDR Engineering in the amount of $10,900.00.
