Burden rate is defined as the total indirect contract costs, calculated as a percentage of the construction company's direct labor. In other words, for every dollar of direct labor allocated to a contract, burden is applied as a percentage of the direct labor. But before a contactor can accurately calculate burden rate, all contract costs assumed by the company must be fully accounted for and factored into the final burden rate equation.

Definition - What does Tack Coat mean? Tack coat is a thin layer of asphalt that ensures the bonding between old and new asphalt layers. It is also used in construction or for renovation of roads to achieve better strength. Tack coat is sticky, which is very important for forming a secure bond between the two layers of asphalt. The lack of tack coat may result in slippage and can cause concentrated stresses leading to total pavement failure. Tack coat is also known as bitumen.
