Bidfident for remediation contractors
Estimating software for site remediation
Remediation estimates turn on cubic metres of soil. In Bidfident you price contaminated soil excavation and clean backfill by the m³, give the excavator and roller compactor their own hours, and add tank removals by the ea and water treatment as a lump sum. Soil haulage and confirmatory testing go in as subtrades, and the superintendent and environmental monitoring follow the schedule by the week.

Sound familiar?
Soil haulage is the biggest number, and the hardest to compare
Haulage and disposal of contaminated soil can be most of the job, and the quotes arrive in different shapes. In Bidfident each bid sits side by side, the lowest is flagged and carried, and you can carry a plug amount until the quotes are in.
Backfill without the extra
Clean granular fill always takes more than the hole, and spreadsheets bury the allowance in a formula nobody checks. In Bidfident each line's material has a waste percentage in plain view, so the extra 10% is there for anyone to see.
Monitoring that outlasts the estimate
The dig runs a week longer than planned, but the environmental monitoring line still shows the old number of weeks. In Bidfident weekly items linked to the job duration follow it, part weeks included.
How Bidfident fits your work
Soil haulage and testing side by side
Enter each bid for contaminated soil haulage and disposal, and for confirmatory testing. The lowest is flagged and carried unless you pick another.
Excavator and compactor at their own hours
Give the excavator its own hours per m³ dug, and the roller compactor its own hours per m³ placed. Each is charged for the hours it runs.
Superintendent and monitoring by the week
Link the site superintendent and environmental monitoring to the job duration. Stretch the job from 5 weeks to 5.5 and both follow.
Extra excavation kept as an option
Price a possible extra dig or a third tank as an alternate. It stays on the sheet struck through, with its amount shown beside the totals, and isn't counted in the bid.
The bid in view as volumes change
Change the cubic metres of soil and the bid total at the top shows how much it moved, straight away.
Earlier versions of the estimate kept
Volumes change as testing comes back. Compare any saved version with now, and restore an earlier one with a click.

Questions
Can I price soil by the tonne as well as the cubic metre?
You can use either unit on a line, since units are free text. Bidfident doesn't convert between them, so price each line in the unit its rate is in.
Can I carry soil haulage before the quotes are in?
Yes. Carry a plug amount for the subtrade, then enter the bids as they come in and carry the lowest or the one you pick.
Can each machine have its own hours?
Yes. Each line's equipment can have its own hours per unit. Leave it blank and it runs for the crew's hours.
Can I add a waste allowance to backfill?
Yes. Each line's material has a waste percentage, and the total includes it.
Can water treatment go in as a lump sum?
Yes. Use LS as the unit with a quantity of 1, and put the hours and materials for the treatment system on that line.
Does it read quantities from site plans or maps?
No. You enter the volumes yourself, from your own measurements or the consultant's report.
Does Bidfident work with Claude or ChatGPT?
Not yet, but it's coming. You'll be able to connect Bidfident to your own Claude or ChatGPT account and ask about your estimates in plain English. The answers will come from Bidfident's own figures, so they match the estimate. It will use the account you already have: Claude first, ChatGPT to follow.
