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.
Semi-monthly employees are paid twice a month, usually on the 15th and the last day of the month. Unlike a bi-weekly payroll, which has 26 payments in a year, a semi-monthly pay schedule has only 24 pay periods. This affects the size of employees' paychecks. It can also factor into overtime calculation, external billing of employee time and deductions for benefits.
