Discuss, consider, and take appropriate action regarding Change Order No. 6 in the amount of ($232,550.27) for Project T5045 - CR 404 Hutto Water Line Realignment (Austin Underground, Inc.) Funding Source: Road Bond P390.

This Change Order revises the original water line pipe design from 18 inch ductile iron to 24 inch HDPE pipe. The change in pipe size and material was necessary to meet the increased demand in water and to alleviate the availability issues of ductile iron pipe. Due to the Contract value of this requested change, the 24 inch HDPE pipe material and the fusion of that pipe is also being removed from this Contract (T5045) and will be bid under a separate Contract (22IFB96). Portable concrete traffic barrier (CTB) is also being added to the Contract, to improve the work zone safety.

The following new items will be added by this Change Order.
