Bidfident

Bidfident for concrete contractors

Estimating software for concrete forming and finishing

Concrete contractors use Bidfident to price a slab line by line: edge forms by the metre, concrete by the cubic metre with a pump charged for its own hours, finish and curing by the square metre, and saw-cuts by the metre. Carpenters, finishers and labourers each take their own rate, rebar quotes sit side by side, and cold weather protection goes in as a lump sum.

Sound familiar?

  • The pump priced for the whole job

    The pump is on site for the pour, not for every hour the finishers spend on the line. In Bidfident the pump on a line can have its own hours per unit, so it's charged for the time it runs.

  • Three crews, one rate

    Carpenters forming, finishers placing and labourers curing don't cost the same, but a blended rate treats them alike. In Bidfident each line takes its trade's rate from the library.

  • Rebar quotes in your inbox

    Rebar quotes come in by email, and the lowest isn't always the one carried. In Bidfident each subtrade's bids sit side by side, the lowest is flagged, and you carry the one you pick.

How Bidfident fits your work

    The pump for its own hours

    Give the pump on the concrete line its own hours per cubic metre and it's charged for that time. Leave it blank, as on the power trowel line, and it runs for the crew's hours.

  • Bidfident screenshot: carpenters, finishers and labourers

    Carpenters, finishers and labourers

    Forms at the carpenter's rate, placing and finishing at the finisher's, curing at the labourer's. Each line takes its trade's rate from the library.

  • Bidfident screenshot: cubic metres, square metres and metres

    Cubic metres, square metres and metres

    Concrete by the cubic metre, finish and curing by the square metre, forms and saw-cuts by the metre. Each line takes a quantity, hours per unit, a material price with a waste percentage, and equipment by the hour.

    Catch a slab line before it goes out

    Lines to check flags a line with no quantity, no cost code, a total of $0, or hours or a material price more than 25% off the library's. Mark a line as right and it stays quiet.

    Insulated tarps and cold weather protection as a lump sum, and the foreman by the week, linked to the job duration.

Questions

Can I price concrete by the cubic metre or cubic yard?

Yes. Units are free text, so m³, cy, m² and m all work. Bidfident doesn't convert between units, so price each line in the unit its rate is in.

Can the pump be priced for less time than the crew?

Yes. Give the line's equipment its own hours per unit. Leave it blank and it runs for the crew's hours, as a power trowel usually does.

Can I add waste to the concrete?

Yes. Each line has a waste percentage on its material, so the concrete can carry 3% and the forms 10%.

Does it work out cubic metres from the slab size?

No. Bidfident doesn't calculate volumes from drawings or dimensions. Work out the cubic metres, then type or paste them in.

Can I price cold weather protection separately?

Yes. Add it as an overhead item, as a lump sum, by the week or by the month. Weekly and monthly items can follow the job duration.

If the pump rate goes up, does a bid I've sent change?

No. A submitted bid keeps the labour and equipment rates it was priced with, so a new pump or finisher 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.
