Discuss, consider, and take appropriate action regarding Change Order No. 3 in the amount of -$55,892.02 for the Great Oaks Water Line (QA Construction), a Road Bond project in Commissioner Pct. 1.  P: 270  Funding Source: Road Bond

This Change Order provides the final balancing for the overrun/underrun of Contract quantities on the project, as a result of addressing field conditions not accounted for in the original plans. This Change Order adds items to the Contract for the Fern Bluff MUD 12" water line connections made after Substantial Completion was achieved for the rest of the project. This Change Order also corrects various item quantities to match the work shown in the plans and installed in the field and adds Item 999-WC07 to assess liquidated damages on the Contractor.

Fern Bluff MUD was not able to shut off the flow of water in the water line during the project. After further investigation of the water line system, the Fern Bluff MUD found a way to turn off the water supply so that the connections to the new water line could be made. The Contractor agreed to re-mobilize back to the project to complete this work. Additional items were added to the contract to pay the Contractor for this work.

The Contractor will be assessed 56 days of liquidated damages because they did not achieve Substantial Completion of the project within the planned contract duration. There were no changes to the contract that would justify additional time.

The following summarizes the new Contract items required for this Change Order.

Item 502-WC01 Water Barrier at Bore Pit - Water filled barriers were added along Brushy Creek Road at the bore pit to protect traffic from the excavated open hole that was located within the clear zone.

Item 506-WC01 Rock Filter Dams (Install) (Ty I) - Added for use in ditch lines to prevent sediment from entering Brushy Creek.

Item 510-W-45 Encasement at Wastewater Line Crossing - The Fern Bluff 12" water line crossed an existing gas line. An encasement was added to the water line to provide the necessary protection between the lines.

Item 999-WC03 BCMUD 8" Water Line for Maintenance Yard - Due to the changes for the water lines on the project, the 8" water line within the BCMUD Maintenance Yard had to be relocated to connect to the new water line.

Item 999-WC04 Stainless Steel Bell Joint Restraints - The Designer required stainless steel bell joint restraints on the Fern Bluff 12" water line. The Contractor's bid did not include the cost for stainless steel materials and provided justification from other projects that indicated that the City of Round Rock does not require stainless steel bell joints restraints. This Change Order pays the difference in the cost of the materials only.

Item 999-WC05 Fern Bluff Standby - The Contractor incurred standby costs when Fern Bluff MUD was unable to shutout the flow of water in their lines at the scheduled time for the water line connection. Contractor crews and equipment waited to give Fern Bluff a chance to turn the water off. Payment of the standby costs is according to Item 4.6 Scope of work and Item 9.7 Measurement and Payment in the TxDOT Standard Specifications.

Item 999-WC06 Extend Encasement pipe - The 24" encasement pipe for the 12" Fern Bluff water line was extended 76'. The plans called for a bore with no encasement pipe in this portion. Adding encasement pipe to this portion will facilitate any maintenance required in the future.

Item 500-WC01 Fern Bluff Mobilization - Pays the Contractor to re-mobilize back to the project after achieving Substantial Completion on the rest of the project.

Item 502-WC02 Fern Bluff Barricades - Pays the Contractor for barricades and traffic control devices used for lane closures during the water line connection work.

Item 105-WC01 Fern Bluff Remove Sidewalk - Pays the Contractor to remove sidewalk at the location of the Fern Bluff water line connection.

Item 531-WC01 Fern Bluff Sidewalks (4") - Pays the Contractor to replace sidewalk that had to be removed to make the Fern Bluff water line connection.

Item 999-WC8 Fern Bluff Bell Joint Restraints - Due to the possibility that water pressure will remain in the abandoned water line, caps and joint restraints will be installed on the ends of the abandoned water line, near the water line connections.

Item 999-WC09 Fern Bluff Bell Flush and Chlorinate Water Line - The new water line will be flushed and re-chlorinated because it has been unused for three months prior to the new water line connections.
