In general, a change order is an amendment to a construction contract that changes the scope of work, usually by changing the work required or adjusting the amount of time required to complete the work. On public works projects, for additional work beyond the scope of the contract, the state or municipality must issue a change order within 30 days of satisfactory completion of all or a portion of the additional work. If a change order is not issued within 30 days, the state or municipality must pay interest at a rate of 1 percent per month.
The change order requirements for public works projects are applied to private construction. Subcontractors and suppliers are also added, so that for any additional work by a contractor, subcontractor, or supplier not in dispute, a change order must be issued within 30 days.
The contractor or subcontractor must request a change order within 30 days of satisfactory completion of any additional work and a request by subcontractor or supplier. If a contractor or subcontractor has requested a change order within 30 days of a request from a subcontractor or supplier, the contractor or subcontractor is not liable for any interest on the unpaid dollar amount for any additional work completed and not in dispute if a change order has not been issued.
An aggrieved party may bring a civil action for violations of the change order requirements in a court of competent jurisdiction for appropriate relief including interest and reasonable attorneys' fees and costs.
