Site work is fuel, rock and machine hours. The material comes by the ton and the truckload, the labor is an operator and a laborer for a week, and the biggest cost, the machines themselves, shows up as fuel, wear parts and a repair bill that lands on no job in particular. The margin is decided by what's underground and by how many loads the pad really needed.
Obra keeps each site as its own job, with fuel and wear parts on the job they were burned on, the rock by the ton against the budget, and the underground surprises recorded as change orders, so you know what each dig made you.
Fuel and iron on the job
Give fuel, wear parts and repairs their own cost codes and log them to the job they happened on. After a season you'll know what a day of your excavator really costs, which is the number your hourly rate has to cover. The overhead guide shows how to split what's per-job from what's per-year.
Rock by the ton, loads by the truck
Set up the budget the way you buy: base rock and fill by the ton, hauling by the load, rentals by the day, labor by the day. When the invoices come in, they go against the right line and the job's page shows the gap. The cost code guide has a short list you can copy.
Ledge, the line, the loads
The three change orders below show up on most sites. Price each one the day it comes up, get the client's okay, then record it so the contract moves with the work. The change order guide keeps the wording short.
Time and materials
Some jobs can't be bid fixed. Enter the estimate as the budget, log costs as they happen, and bill from what the job's page shows you've spent. The cost-plus invoicing guide covers the routine that keeps the client from arguing the invoice.
What Obra isn't for an excavation contractor
Not telematics, not dispatch, not a takeoff tool. Obra is the money on each job, in English and Spanish, from receipts your crew already sends, exported clean to the accountant.
