“Supervision is already covered in O&P.” That line gets written into claim files every week, and it strips real cost out of large loss estimates.
Here is the technical problem with it.
General contractor overhead pays for running a business. Office, insurance, accounting, estimating, administration. It spreads across every job the contractor runs, which is why it is a percentage. Profit is the return for taking the project on. Neither one pays for a superintendent standing on the job site.
Site supervision on a complex loss is a direct cost of that specific project. Sequencing eight trades through a burned-out structure, managing safety and access, coordinating inspections, and running quality control through drying and rebuild. That is labor performed on the job, the same as hanging drywall.
Xactimate is built the same way. Unit labor rates include a working crew component, which covers a trade supervising its own work. A drywall foreman watching drywall. Dedicated cross-trade supervision is not in those rates, and that is exactly why supervision exists as its own line item. If it lived inside O&P or the unit rates, the line item would not need to exist.
The test our estimators apply is simple. Would a contractor bidding this project staff dedicated supervision? On a small kitchen water loss, probably not. On a large fire, a multi-building wind claim, or anything with phased occupancy, no competent GC runs the job without a superintendent, and no real-world bid excludes that cost.
This is the kind of line item that separates a complete large loss estimate from one that quietly leaves money on the table. Every estimator on our staff holds Level III Xactimate certification, and catching items like this is the reason we only write complex and large loss.
If you have a file where the scope needs to reflect how the work actually gets built, we should talk.
