Does your drawing say one thing, but your building say another?

Most buildings carry a version of the same problem. The drawings exist. The plans are on file. But somewhere between when they were first produced and today, the building changed — and the documentation didn't keep up.

For refurbishment and development projects, that gap isn't just an inconvenience. It's a risk that compounds with every decision built on top of it.

When legacy plans aren't enough to build from.

AVCON, partnering with Mobilitas and Multi Quantity Surveyors, brought FireFly in at a critical project milestone on The Lenox — a heritage building on a slope, untenanted for over a year, with no confirmed internal dimensions and unverified floor levels.

The team needed a precise 3D model to move forward. The existing 2D drawings simply weren't reliable enough to build from.

Old plans. Unverified levels. A heritage building with no confirmed internal dimensions. The kind of situation where assumptions become expensive very quickly.

One day. 630 scans. Every level verified.

FireFly scanned The Lenox in a single day. 630 individual scans captured every floor level, every internal dimension, and every spatial condition of the building as it actually stood — not as the old drawings suggested it did.

The result was a precise 3D digital model that finally reflected what was physically there. Delivered fast enough to keep the project moving at full speed.

Why verified data matters at the critical moment

Refurbishment projects are particularly vulnerable to the gap between drawn and actual. Heritage buildings shift. Levels vary. Decades of alterations accumulate without ever making it back onto a plan. When a project team needs to make decisions — on structure, on fit-out, on cost — they need to know what they're actually working with.

Accurate data doesn't just reduce risk. It removes the uncertainty that causes delays, drives up costs, and forces teams to revisit decisions they thought were already made.

At The Lenox, verified measurements meant the project team could move forward with confidence from that milestone onward. Not working around the unknowns — working from verified facts.

The question every project team should ask early

Does your drawing reflect your building?

If the answer is uncertain — or if the plans haven't been verified against what's physically there — that uncertainty will surface somewhere in the project. Better to surface it by choice, at the start, than by consequence, under pressure.

Digitise once. Move forward with confidence.
