The Hidden Cost of Doing BIM In-House (And When Outsourcing Makes Sense)
Every AEC firm eventually asks the same question: should we hire more Revit modellers, or should we bring in outside help for BIM?
Most firms answer this based on gut feeling — "we've always done it in-house" or "outsourcing feels risky." Few actually run the numbers. So let's run them.
What In-House BIM Actually Costs
A full-time Revit MEP modeller in Australia costs roughly AUD 75,000–95,000 a year in salary alone. Add superannuation, software licenses, training time, and the ramp-up period before they're fully productive, and you're looking at closer to AUD 100,000+ per head, per year.
Now the real question: is that person modelling 12 months a year, every year, at full capacity? For most firms, the honest answer is no. Project pipelines are lumpy. You're overstaffed in slow quarters and scrambling in busy ones — hiring contractors last-minute at a premium, or worse, pushing deadlines.
The Real Cost Isn't the Salary — It's the Idle Time and the Panic Hiring
This is where in-house BIM quietly bleeds money:
- Senior engineers doing repetitive modelling work instead of design decisions that actually need their expertise
- Downtime between projects where BIM staff have nothing billable to work on
- Emergency contractor rates when a deadline suddenly needs more hands
- Onboarding time lost every time a new hire has to learn your standards from scratch
None of this shows up as a line item labelled "hidden BIM cost." It shows up as margin erosion nobody can quite explain.
When Outsourcing Actually Makes Sense
Outsourcing isn't right for every firm. But it tends to make sense when:
- Your project pipeline is inconsistent and hiring full-time doesn't match demand
- You need overflow capacity during peak periods without a long-term headcount commitment
- You want senior staff focused on design and client relationships, not routine modelling
- You're entering a new service area (like scan-to-BIM or COBie handover) without wanting to build that capability from scratch
How BIM365 Fits In
We provide dedicated Revit MEP modelling and coordination support — priced by scope, not inflated day rates, with resources who work your time zone and follow your standards from day one. No long-term lock-in, no re-explaining your project every time.
The firms that get the most value from outsourcing aren't replacing their team — they're freeing their best people to do the work only they can do.
