18-2-421. Notice. When a public works project is accepted by the public contracting agency, a notice of acceptance and the completion date of the project must be sent to the department. However, in the case of public works contracts that amount to $50,000 or less in cost, the notice of acceptance and the completion date of the project is not required unless the department requests that information. The 90-day limitation for filing an action in district court, as provided in 18-2-407, does not begin until the public contracting agency notifies the department of its acceptance of the public works project.
