Bidfident for asbestos removal contractors
Estimating software for asbestos removal
Licensed asbestos removal is priced in enclosures, metres of pipe lagging and square metres of floor tiles, with air monitoring running every week the enclosure is up. Bidfident lets you price each removal line with operative hours, polythene and consumables with waste, and negative pressure units at their own hours. Hazardous waste carriage goes in as a subcontract, and weekly air monitoring and supervision follow the programme.

Sound familiar?
Air monitoring left at the old number of weeks
The programme slips from 5 weeks to 6, and the air monitoring and supervisor lines still show 5. In Bidfident weekly items linked to the job duration follow it, so the extra week is priced.
Plant hours that don't match the work
Negative pressure units run around the clock while the enclosure is up, far longer than the removal gang works, but a spreadsheet row has room for only one set of hours. In Bidfident each line's plant can have its own hours per unit, apart from the gang's.
Hours typed wrong on one line
One pipe lagging line goes in at 0.06 hours a metre instead of 0.6, and nobody spots it before the tender goes out. Lines to check flags a missing quantity, a line that comes to zero and, for a line picked from your library, hours or a material price more than 25% off the library's, so you look before you send.
How Bidfident fits your work
Air monitoring by the week
Put the independent analyst's air monitoring and the asbestos supervisor in by the week, linked to the job duration. Add a week to the programme and both follow.
Negative pressure units at their own hours
Give the enclosure line's NPU its own hours per square metre. It runs around the clock while the enclosure is up, so it's charged for its own hours, not the gang's.
Lagging by the metre, tiles by the square metre
Units are free text, so pipe lagging goes in by the m, floor tiles and adhesive by the m² and decontamination units by the nr. Each line adds up hours and material as you go.
Hazardous waste carriage as a subcontract
Enter each waste carrier's quote for carriage and disposal. The lowest is flagged and carried, or pick another. No quote yet? Carry an allowance.
Checks before the asbestos tender goes out
Lines with no cost code, no quantity, a total of zero, hours with a zero rate, or hours or a material price more than 25% off the library's are flagged, so a mistyped pipe lagging or floor tile rate gets a second look. Mark a line as right and it stays quiet.
Contingency for hidden asbestos
Carry a contingency for asbestos found behind walls and above ceilings, then overheads and profit, with the bond and insurance on the subtotal after them. Every amount is exact to the penny.

Questions
Can air monitoring follow the programme?
Yes. Put it in as a weekly preliminaries item linked to the job duration. Change the weeks and it updates, part weeks included.
Can I price pipe lagging by the metre and floor tiles by the square metre?
Yes. Units are free text, so each line can use its own unit. Bidfident doesn't convert between units.
Can I add polythene and consumables with a waste allowance?
Yes. Each line has a material price and a waste percentage, and the material total includes the waste.
Can I price a DCU as a single item?
Yes. Use nr with hours and material per unit, or save it as an assembly in your rate library so it fills a whole line at once.
Can I carry waste carriage before the carriers have quoted?
Yes. Carry an allowance for the hazardous waste subcontract, then enter each carrier's quote as it comes in. The lowest is flagged and carried unless you pick another.
Can negative pressure units run longer than the gang works?
Yes. Give the enclosure line's plant its own hours per unit, more than the gang's when the NPUs run around the clock. Leave it blank and they run for the gang's hours.
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.
