Guerra Construction, LLC for the Somerset 8 -inch Water Main Improvements Project.

Guerra Construction, LLC a Construction Contract for the Somerset 8 -inch Water Main Improvements Project in the amount of $93,153. During a review of the distribution system in the Chisholm Cove area, the City's water model indicated an insufficient fire Flow for the developed properties in this area. To remedy this, the City will construct two 8 -inch water lines that will interconnect existing dead-end water lines between Chisholm Trail and the southbound IH -35 frontage road. This will also eliminate required monthly Flushing for water quality. Because the "As Built" drawings were vague, an additional 19 Linear Feet (L.F.) of 8 -inch and 10 L.F. of 6 -inch PVC waterline was needed to complete the project. In addition, it became necessary to add an additional tapping saddle and valve in order to keep the shopping center and fitness gym connected to our water system. Utility Staff recommends execution of Quantity Adjustment/Change Order No. 1 in the amount of $6,040, which will increase the total contract amount to $99,193. Staff recommends approval.
