The unit weight calculation is: Unit Weight = Weight of Concrete Ã· Volume of Concrete. This calculation can be rearranged for volume, which is known as the yield calculation. In other words, it is the volume that a certain weight of material will yield.rom the batch ticket, we find that 5 cubic yards of concrete were batched. The total weight of cement, sand, and stone was 18,860 pounds, and 156 gallons of water were also batched. Since we know that water weighs 8.33 pounds per gallon: 156 gallons of water X 8.33 pounds per gallon = 1,300 pounds of water.
The long-awaited overtime rule from the Labor Department would more than double the threshold at which employers can avoid paying overtime, to $970 a week by next year. That would mean salaried employees earning less than $50,440 a year would be assured overtime if they work more than 40 hours per week. To keep up with future inflation and wage growth, the proposal will peg the salary threshold at the 40th percentile of income, individuals familiar with the plan said.
An employer must pay its employees at least the minimum wage for all hours worked, and time and one-half overtime pay based on an employee's regular rate of pay for all hours worked in excess of 40 in a workweek unless the employee is exempt for some reason.
