Staff Summary
• Stearns School Rd. Bridge Deck Resurfacing: LCDOT Change Order No. 2
• Change Orders need to be approved by the standing committees for cumulative net increases over 10%.
• This project is under contract with Lorig Construction under an original awarded contract at bid unit prices totaling $309,905.
• Change order #1 added items that were necessary for providing power to the bridge signal, installing a wooden protective shield under the bridge to prevent debris from falling onto the Tollway and an increase in the amount of patching anticipated due to conditions that were found in the early stage of removal.
• This change order #2 is now being submitted following a structural engineer’s recommendation based on the deteriorated existing bridge conditions that were uncovered. The north half of bridge repairs are completed and costs determined by field measurements of the quantities for the items. The project has been halted for the winter. Estimated costs are included in this change order. The south half of the bridge will have the deck hydroscarified for preparation of the new overlay in early 2010. Exact final quantities will be known once this work is underway and completed in 2010.
• The north half of the bridge cost approximately $227,629. The south half is estimated to cost about $317,576 based on current estimates and the costs of re-mobilization, etc.
• A balancing change order will be submitted in the spring of 2010.
• Summary: original awarded contract - $309,905; Change Order No. 2 - $135,300; sum of all changes - $235,300.
