CM-11-04-074ROUND ROCK, TEXAS PURPOSE. PASSION, PROSPERITY, City Manager Approval Summary Sheet Consider executing Quantity Adjustment/Change Order No. 1 with Chasco Constructors Item Caption: for the North Mays Extension Project. Approval Date: April 15, 2011 Department: Infrastructure Development and Construction Management Project Manager: Lance Shellenberger Item Summary: This quantity adjustment/change order is needed to address the following: • While excavating for the new roadway, the contractor discovered 2-12" water mains that require extension beyond the proposed sidewalk, a sewer service that requires extension, and an air release valve that needs to be abandoned. • The contractor also discovered a buried wastewater manhole that needs to be brought to proposed finish grade. • The Crystal Park sign on the northeast corner of North Mays Street and Old Settlers Boulevard needs to be removed and disposed of. Its removal was not negotiated in the right-of-way acquisition.) • An existing storm sewer junction box planned to be capped and left in place had two existing lines coming into the box at an elevation that would not allow it to be capped, so the installation of a traffic -rated ring and cover at proposed pavement grade is required. • A special storm sewer manhole is required to resolve a conflict with a proposed storm sewer line and an existing storm sewer line. • The plans did not call for the type of countdown peds, therefore, at the request of the signal department, a change is required to meet current City standards. • A minor adjustment to an existing phone cable is necessary to avoid a conflict with the proposed sidewalk. Strategic Plan Relevance: 26.0 - Construct major element of transportation and mobility system as approved by Council in the Master Transportation Plan.
