The Build Tech Brief

By Paul Hedgepath
When I first got into BIM about twenty years ago, 3D coordination was still more promise than practice for many contractors. Back then, getting trades to sit in a room and clash-check a model felt like a big step forward.
Now it’s an expectation on most projects. When it’s done well, it saves time, money, and a lot of headaches in the field.
What 3D Coordination Really Is
3D coordination is exactly what it sounds like. It takes all the parts and pieces of a project such as structure, mechanical, electrical, plumbing, and finishes and brings them together in one digital model.
The goal is simple. Find conflicts before they show up on site so crews are not cutting holes in slabs or rerouting ductwork at the last minute.
How We Use It Today
We use 3D coordination on just about every job that has tight systems or complicated layouts. It does not replace field experience. It supports it.
Our teams still walk the job, double-check conditions, and measure what matters. The model is a tool, not a guarantee. But when done right, it makes the handoff between design and installation smoother for everyone.
It’s About More Than Software
One thing I’ve learned is that good coordination is not just about software. It is people sitting down together, asking the right questions, and trusting the model enough to raise issues early.
The sooner you find a clash, the easier and cheaper it is to fix.
Owners Expect It Too
Owners are seeing the value too. They want to know that what they see in design is what they are going to get. 3D coordination helps deliver on that promise.
It also makes handover easier. A coordinated model becomes the foundation for as-builts, maintenance planning, and future renovations.
Where to Start if You Haven’t
If you are not using 3D coordination yet, start with the basics.
  • Get your key trades involved

  • Hold simple clash detection meetings

  • Focus on problem areas first like mechanical rooms, tight corridors, or areas with overhead congestion

  • Adjust the design or schedule before you get stuck later

What It’s All About
I believe 3D coordination is one of the best ways to connect design and construction. It takes teamwork to make it work and the payoff is clear.
Less rework. Fewer surprises. A smoother job from start to finish.
If you want to talk more about how we are using 3D coordination on real projects or compare lessons learned, I am always glad to share ideas. Let’s keep building smarter together.
