Approval of the change order is necessary to pay costs for work of an emergency nature on the water main replacement project. The total completed project cost is $711,534.72. Construction on the project is complete, all quantities have been measured and final costs computed. BACKGROUND: On October 2, 2006, the City Council authorized a contract in the amount of$498,425 with Bodine Services of Decatur to replace the water line in Green Street between Monroe Street and Main Street. On April 16, 2007, the City Council approved a change order in the amount of $165,000 adding a second phase of work to replace the water main in Green Street west of Monroe Street to Van Dyke Street. The total amount of the contract approved by Council for both first and second phases of the work is $663,425. The second phase of the Green Street water main replacement project experienced an unusually large amount of unplanned work. The extra work included both emergency and non-emergency items. Construction work may be considered of an emergency nature when it meets one of two criteria: 1. Purchase of materials or services that are crucial to avoiding prolonged downtime or unnecessary lengthening of a task or job. 2. Purchase of materials or services that are made to protect public health, safety and welfare due to an event that has occurred or is expected to occur soon. On the Green Street proj ect, emergency purchases included replacements of failed water service lines, extra work resulting from conflicts with abandoned utility lines not previously known and extra work to identify the vertical elevation of known utility lines to avoid conflicts with the water main. On phase 2 of the Green Street Water Main replacement project, the total amount of emergency purchases is $62,322.67.
