SUBJECT:
This item is requesting a change order to Resolution R13-278 Replacement to the Upper Roof Structure of the Sci-Tech Building located at 18 W. Benton.
PURPOSE:
The Sci-Tech roof replacement was approved in October 2013. Work commenced in mid-November 2013. The work was suspended during the winter months after 50 % of the completion. The roof was secured for the winter months. During this period leaks would continue which are attributed to the sloping mansards and the drainage valleys.

The change order request is for $55,062.18. Work under the existing contract and resolution is underway.
