Line 14 states the number of regular hours and the normal labor rate for this change. Line 15 shows the number of overtime hours and the overtime rate. By the way, AIA documents allow travel time to be charged to a change. Obviously, your painters will be working eight hours on the job each day, so travel time will show up on their time card at an overtime rate. This includes costs incurred by the painting contractor for taxes, insurance, or assessments required by law, such as workers' compensation, unemployment, or social security.
Supervision includes onsite and offsite supervision.
The remaining 6 percent helps recover the costs of a field superintendent overseeing all jobs and a yardman. To determine the percentage for offsite supervision, add up these offsite personnel annual expenses such as salary, cellular phone, truck expenses, etc., and divide this cost by annual payroll. If you charge much more than 15 percent for supervision, this cost will probably be questioned. Determine the cost of your spray equipment. Therefore, I take the number of man-days in the change order and divide it by two.
