The High Service Pump Station and Chemical Feed Building Roof Replacement Change Order #2 for $4,380.00 is presented for Council approval.  It covers the cost of purchasing and installing new wall caps for the High Service Pump Station.  The original specifications called for the new roof membrane to be terminated under the wall caps and assumed that the existing wall caps could be removed and reused.  Instead, the existing wall caps are too snug to allow proper termination of the membrance underneath the cap.  New caps with the appropriate dimensions are required.

There are no viable alternatives to approving the change order.  The wall caps are necessary to prevent roof leaks and new ones must be fabricated and installed because the old ones do not fit.

There is adequate funding in the FY2013 Water Treatment Division Operations and Maintenance budget to cover this change order.  The total project cost will increase from $68,680.00 to $73,060.00.  The total cost of Change Orders #1 and #2 exceeds 10% of the original contract cost, so City Council approval is required. 

Staff recommends that the City Council approve Change Order #2 for the roofing contract with Donaldson Construction and Roofing in the amount of $4,380.00.
