About this building

Operators putting roof and building-envelope work out to tender without a surveyor on staff. This is a live twin we built and run for the customer, and the situations shown here are real ones from the site. Measurements are taken against the model geometry, so an area or a length is read rather than approximated. A scope written from them can be exported and sent to whoever is pricing the work.

The problem: three quotes, three different roofs

A roof needs doing, so three contractors come out. One paces it, one works off an old drawing, one measures properly. The three numbers that come back are not comparable, and the cheapest is usually the one who measured the least.

Nobody is being dishonest. There is no single measurement any of them can work from, so each produces their own and prices against it.

What the twin holds

The roof as its own surface, with its area, its falls, its drains, its penetrations and its parapet all readable off the model.

What came out of it

One scope, sent to all three, so the three prices are for the same piece of work.

Copilot measures the roof

The request is a report for the roofing contractor with measurements, so he knows what he is walking into. The copilot isolates the roof and reads it off the model: 412 square metres, two-ply modified bitumen, falling at 1:50 to four internal drains, eleven penetrations, thirty-eight metres of parapet. That goes out as a scope report he can price against. The numbers are read, not estimated.

The sub oven on the asset register. Sub oven, TurboChef Sota.

The oven opened on the line. It takes two cycles to reach set point in the morning, which is the complaint the staff actually raised. Its history: blower motor replaced, catalytic converter cleaned, door seal replaced for heat loss, and a deep clean with a recalibration after it.

  • Quoting from one measurement:
    Every bidder prices the same area, because there is only one.

  • Naming the detail that costs:
    Penetrations, falls and parapet are in the scope before anyone visits.

  • Keeping the kitchen record:
    Line equipment carries its own service history alongside.
