Financial Consideration
State statutes require City Council approval of a change order when the cumulative cost of change order exceeds $50,000. With approval of this change order, the City Manager will be able to approve the change order to a cumulative value of $50,000 without additional Council approval. Also, the City, as an owner, reserves the right to increase the amount of the work to be performed in a given construction contract by an amount not to exceed twenty-five (25%) percent of the original bid. The amount of the original contract was $898,656.84 and 25% value of this contract is $243,134.96. The Cumulative amount of Change Order #2 is $111,046.00 ($84,916.00 increases and $26,130.00 decreases) which requires council approval. The net amount for Change Order #2 is $58,786.00.
