Definition
A contractor usually provides labor but sometimes he contracts
the entire structure without the owner providing any material. In
inquiring about expenses, try to provide the details as called for in this
subsection. Try to assess the construction enterprise if the net income
is realistic. Usually contractors are allowed a margin of profit of about
15 percent, which is added to the cost estimates of materials and labor.
The constructed price cost of labor is 30-40 percent of the total cost of
materials.
