Budget estimate

$100,000 – $200,000,000

Based on the information provided, the budget amount for this project can be estimated by considering the original contract award amount and the cost of change order/extra work order. The original contract award amount is $214,831,567.83, and the cost of change order/extra work order is $116,879.04. Therefore, the total budget amount for this project can be estimated to be around $214,831,567.83 + $116,879.04 = $214,948,446.87. However, this is an amendment to the original contract, so the actual budget amount may be lower. A more realistic estimate would be around $116,879.04, considering only the cost of change order/extra work order. The budget amount may be influenced by factors such as the scope of work, the materials required, and the labor costs.
