BIM Modelling

Federated-model coordination, clash detection and one source of truth — every drawing derived from one coordinated model, with conflicts caught before they reach site.

Every detail lives in one BIM model — and every drawing comes out of it. A 2D set can't surface every clash, and it can't keep up with change: through approvals and coordination the design moves constantly, and on 2D someone has to copy each change across every detail, elevation and section by hand — exactly where human error creeps in. We model in 3D from an early stage, so there's a single source of truth: change it once and every manufacturing and installation drawing updates from it, coordinated with each other and with the other trades.

How we work

01

Model early

We implement BIM from an early stage and build the façade in 3D, so coordination starts before the drawings harden — not after they're already in conflict.

02

Clash detection

We clash-detect the façade model against the structural and MEP models, so interface conflicts are found and resolved before steel is fabricated — caught in the model, not discovered on site.

03

One source of truth

Every detail, elevation, section and fabrication/installation drawing is generated from the model. Change it once and it propagates everywhere, coordinated with the other trades — no drawing left out of step.

04

Checked before issue

Our design managers and quality coordinators review the model before anything is issued — eliminating the human error a hand-maintained 2D set invites, and speeding the whole process up.

05

Visualise & approve

We produce photorealistic CGI of the systems straight from the model — invaluable for showing clients and architects, and for getting sign-off on the difficult details and solutions.

What you receive

Federated 3D coordination model (IFC)
Clash-detection reports against structural and MEP
Fabrication-ready geometry and sequencing

What it means for you

One coordinated model means changes never slip through and clashes never reach site. Every drawing comes out of the model and is checked by our design managers and quality coordinators before issue — so you get speed without the human error a 2D set invites. A clash resolved in the model costs an email; the same clash on site costs a crane day and a variation.
