How to price a scaffolding job without guessing

A scaffolding quote is usually two things: a rate applied to a measure, and an allowance for everything the measure does not cover. The first part is arithmetic. The second is judgement, and it is where jobs are won at a loss.

Start with what is actually being built

Pricing before you know the structure is guessing with extra steps. The questions that change the number are not subtle: how long is the run, how high, how many lifts are boarded, does it turn a corner, what is the ground like, what duty is it for, and how long is it up.

Duty matters more than most quotes reflect. A scaffold for a bricklayer carrying material is set out at shorter bays than one for a painter, which means more standards, more fittings and more labour for the same face area. Two jobs with identical meterage can be materially different jobs.

The measure

Most firms price on face area — length along the elevation times the height of the scaffold. Some price linear metres per lift. Either is defensible; what is not defensible is a quote that does not say which, because that is the argument you cannot win six months later.

• –State the basis on the quote, in a line, every time.
• –Say how returns are measured, because the client will assume the answer that suits them.
• –Separate the boarded lifts from the face — a scaffold boarded at every lift is a different job.
• –Price loading bays, staircases and hop-ups as their own items rather than burying them in the rate.

The allowance nobody writes down

Every experienced estimator carries an allowance for the things that are not on the drawing: awkward access, a yard forty minutes away, ground that will need sole boards and stepping, a client who changes their mind. That allowance is usually in someone's head rather than on the quote, which means it disappears when that person is on holiday.

Writing it down does two things. It makes the number repeatable when someone else prices a job, and it makes it reviewable — you can look back at ten jobs and ask whether the allowance was right, which is impossible if it was never recorded.

Hire is not an afterthought

Erect and dismantle are one-off costs. Hire is revenue that accrues for as long as the material is on site, and it is the part of a scaffolding business most often given away — a job that overruns by six weeks is six weeks of hire that was either invoiced or was not.

That requires knowing when the scaffold went up and when it is due off, per structure, rather than per job. A contract with eleven structures on it has eleven hire periods, and treating them as one is how a firm ends up discovering that three of them came down in April.

The part that actually decides profitability

It is not the rate. It is whether the adaptations during the hire get recorded and charged. A lift added here, a bay struck to let a delivery through there, a section sheeted because the weather turned — each one is work done, and each one is invisible a year later unless somebody logged it at the time.

This is the single most recoverable money in scaffolding, and it is recovered by a form on a phone at the moment the work happens rather than by memory at the end of the month. That is what the platform is built around: the structure holds its own history, so an adaptation is a record rather than a recollection.
