The districts use the Strategy 144, Contracted Routine Maintenance budget for district or state let Routine Maintenance Contracts (RMC's). Districts may let "district let" RMC's up to an estimated amount of $300,000. Any project with an Engineer's Estimate of $300,000 or more must be let as a "state let" project through the Maintenance Division. Districts have full authority to schedule and let projects without additional approval within their allocated budget.
