The short version. Six steps, in order. Fill it out on site, the day the work happens, and get it signed before you leave.
The six steps
1
Project info
Which job, what date, and what the extra work was. Write what happened in plain words — “removed 40 LF of unmarked conduit at the north footing,” not “extra work per direction.”
2
Labor
Who, what trade, how many hours. Names, not just a headcount.
3
Material
What you used and how much. Quantities with units.
4
Other costs
Equipment, rentals, disposal, delivery. This is the step people skip, and it’s real money.
5
Attachments
Photos of the condition before you fixed it, plus delivery tickets. Photos taken after the fact prove nothing.
6
Approval
A signature from whoever directed the work, on site. → Getting a signature
What you can leave blank
Material and other costs genuinely don’t apply to some tickets. Labor, the description and the signature always do.Next
Cost Code vs. PCO
Two numbers, two audiences.
