Precast concrete is a construction product produced by casting concrete in a reusable mold or form which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast, standard concrete is poured into site-specific forms and cured on site.
What They Are. Semi-monthly payments are payments made twice per month on the 1st and 15th rather than once per month on your regular due date. The balance due remains unchanged; if your mortgage is $1,200 per month, you would make a payment of $600 twice each month.
A semi-monthly payroll occurs twice per month, such on the 15th and last day of the month. Both payrolls have their advantages. Normally, a year has 365 days; however, a leap year has 366 days. A biweekly payroll has 14 days and 26 pay periods, which amounts to 364 days. Over time, this difference of one day during regular years and two days during leap years results in a 27th paycheck for biweekly workers. A semi-monthly payroll always has 24 pay periods, which results in less time and money spent on running payrolls.
