MO HB409

Narrows the definition of "construction" to exclude maintenance work and clarifies that maintenance work does not include major repairs (defined as work exceeding the replacement cost of existing facilities).

Limits prevailing wage determinations by the Department of Labor and Industrial Relations to nine specific counties and any city not within a county; all other counties must use the state average weekly wage as the prevailing hourly rate.

Requires the Department to consider wage rates from trade organizations with 501(c)(6) tax-exempt status when determining prevailing wages in the designated counties.

Establishes that trade organizations may submit wage rate data collectively, and members cannot be required to participate in subsequent administrative challenges to the wage determination based on that data.

Maintains the annual wage order process with initial determinations by March 10th and final determinations by July 1st, with provisions for objections and administrative hearings.
