Bidfident for hazardous materials contractors
Estimating software for hazardous materials removal
Hazardous materials work mixes square metres and single items on the same job. Price lead paint removal on steelwork by the m² with a vacuum blasting unit at its own hours, PCB capacitors and fluorescent tubes by the nr, and mould remediation by the m². Bidfident carries hazardous waste disposal as a subcontract, keeps air monitoring in step with the programme, and adds the bond and insurance on top.

Sound familiar?
Lead, PCBs and mould on one sheet
Each hazard has its own unit, gang hours and consumables, and a spreadsheet built for one gets bent to fit the rest. In Bidfident every line carries its own unit, hours per unit and material, and the cost report totals each cost code, so every hazard shows its own figure.
Counting fittings by the hundred
Hundreds of capacitors and over a thousand tubes, priced by hand with a calculator beside the sheet. In Bidfident you type the count, the hours and the rate per item, and the line totals as you go.
Blasting plant over-charged
The vacuum blasting unit doesn't run every hour the gang is on the steelwork, but a single row charges it as if it did. In Bidfident the unit gets its own hours per unit, apart from the gang's.
How Bidfident fits your work

A total for each hazard
The cost report totals lead paint, PCB capacitors, fluorescent tubes and mould by cost code under each division. Filter by area or cost type, and click a row to jump to it.

Vacuum blasting at its own hours
Give the blasting unit its own hours per square metre of steelwork, so it's charged for the time it runs, not the gang's.

Capacitors and tubes from your library
Type a description and pick a task, material or assembly from your rate library, with its rate, to fill the line.

One rate library for every hazard
Keep operative rates, blasting plant, consumables and tasks with hours per unit in one company library. Every estimate uses it.

Monitoring and supervision by the week
Air monitoring and the removal supervisor by the week, linked to the job duration. A 4-week programme that becomes 5 picks up the extra week.

Hazardous waste carriers compared
Enter each waste carrier's quote for carriage and disposal, see the lowest flagged, and carry it or the one you pick.

Questions
Can I price capacitors and tubes by the item?
Yes. Use nr as the unit, with hours and a rate per item. Units are free text.
Can lead paint, PCBs and mould have their own cost codes?
Yes. Start from cost codes named after the NRM2 work sections, or paste your own list, such as CESMM, in from Excel or QuickBooks with a preview first.
Can I see what each hazard costs on its own?
Yes. The cost report totals each cost code under its division, and you can copy the whole estimate by cost code as CSV.
Can I price mould remediation as an option?
Yes. Switch the line off as an alternate. It stays on the sheet struck through, and its cost before markups is shown beside the totals, but it isn't in the tender.
Does it count fittings from the drawings?
No. Bidfident doesn't read quantities from drawings or plans. You enter the counts yourself.
If my operative rate goes up, does a tender I've sent change?
No. A submitted tender keeps the labour and plant rates it was priced with, so raising the operative or blasting unit rate in your library doesn't move a price you've already sent.
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.
