Note: If local conditions indicate that aggregate production will be subcontracted, and that aggregate producers will likely pay Davis-Bacon wage rates, no reduction for labor should be made to the basic rock cost. Also, not all contracts require Davis Bacon rates in basic rock and hauling costs. Check with your Contracting Officer.

Here's the math. Let's take a mid-sized crushing operation and try to quantify these costs. Assume: • 250 tons per hour production • Crushing price of $2.50 per ton • 3 crew members on shift, average hourly wage $20 per hour • 60 hours per week operation • Crushing season 26 weeks or 130 Days – Approximately 6-7 months of operation
2. Amount of processing required for aggregate production depends on • Nature of raw materials • Desired attributes of the end products Four procedures adopted: 1. Particle size reduction – crushing 2. Separation into particle size ranges – screening / sizing 3. Elimination of undesired materials – washing 4.
