1.2.2.  Engineering Cost Estimate.

The basis of an engineering estimate is labor and material costs for significant work elements. Instead of dividing the estimate for concrete into its major components, as the contractor might do, the engineer will estimate so much for materials and so much for labor. For example, if the requirement is for a concrete patio, the engineer might estimate $70 a cubic yard in place for material and $20 a cubic yard for labor costs multiplied time the amount of cubic yards to be poured. This price would include the cost of cement, aggregate, reinforcing steel and forms, but it usually excludes all overhead and profit.
