There's a moment every project director knows. The project's in CC phase, the design programme is slipping, consultants are trading RFIs like they're running a paper exchange, and your design manager — the one on a $180K salary — is buried in meeting minutes and chasing drawing registers instead of driving decisions. You're paying full freight for someone whose bandwidth is consumed by one project, and the next job in the pipeline has nobody looking after it.
This is the full-time design manager trap. And it's costing builders more than they realise.
The way it's always been done
For decades, the default move for any builder with active projects above a certain scale has been to hire in-house design managers. Permanent headcount, full salary, full benefits, full exposure. The logic seemed sound: design coordination is complex, relationships matter, you need someone across the detail.
But that logic was built for a different market. A market where project pipelines were steadier, scopes were more predictable, and the regulatory environment wasn't shifting underneath you every eighteen months.
Since DBP Act reforms landed in NSW, the complexity of design coordination has increased sharply. Class 2 buildings now carry a compliance chain that runs through design practitioners, principal design practitioners, and performance solutions — all of which need active management, not passive oversight. Add NCC 2022 changes to fire, accessibility, and energy, and you've got a consultant coordination task that demands specialisation, not just availability.
A general-purpose in-house hire doesn't always cut it. And yet, that's still the default.
The hidden cost calculation builders miss
Here's what a permanent design manager actually costs when you run the full number:
Base salary, super, leave entitlements, recruitment fees, onboarding time, software licences, and overhead. You're looking at somewhere between $220K and $280K all-in annually for a mid-to-senior level hire in Sydney or Melbourne. And that's before you account for the periods between projects where they're underutilised, or the months at the start of a new project where they're still getting across the documentation.
Now compare that to what you actually need across a typical project lifecycle. DA phase is light on design management — it's mostly about consultant assembly and scope coordination. Design intensity spikes at CC, peaks through IFC, and then demands a different skill set again at construction phase for RFI management and site-level coordination. The demand curve is not flat. But a full-time hire costs you as if it is.
"The greatest waste in most organisations is the waste of human potential — people deployed against fixed structures that no longer match the work."

What actually happens on complex projects
On a high-rise residential project in CC phase, the design manager's week looks something like this: two hours chasing a hydraulics drawing that's holding up a BASIX amendment, three hours in a coordination meeting that should have been an email, and an afternoon trying to reconcile two versions of a fire compartmentation drawing that the FEC and the architect have each marked up differently.
On that same week, the incoming project — a mixed-use development two suburbs over — has its first DD coordination meeting, and nobody in-house has capacity to attend properly.
This is the staffing gap that never shows up in a budget review. The pipeline problem. Builders with two to five projects running concurrently almost always have at least one project that's under-managed on the design side at any given time. That's where scope creep hides. That's where construction issues originate. That's where OC delays begin — six months before anyone notices.
The specialist gap
There's a deeper issue beyond headcount. Design management across a DBP Act environment isn't a generalist role anymore. Managing the Design and Building Practitioners Regulation 2021 compliance pathway — design compliance declarations, regulated design documentation, lodgement through CACS — requires practitioners who understand how the compliance framework actually operates, not just the surface-level administrative steps.
Same goes for NCC performance solutions. If a project is running a performance alternative on fire safety or structural loading, the design manager coordinating that process needs to understand the pathway: the FER brief, the assessment method, the documentation standard. A generalist hire with residential project experience doesn't automatically have that capability. And training someone up to it on your time and your dollar has a cost too.
"The question is not whether you can afford to specialise. The question is whether you can afford not to."
— Ken Schwaber, co-creator of Scrum and advocate for specialist-led delivery frameworks
What the industry has been slow to accept is that design management has fractured into specialisms. Compliance management, coordination management, consultant commercial management, programme management — these are distinct skill sets. Deploying one person against all of them is how things fall through the gaps.
The flexible model: what it looks like in practice
The smarter builders — particularly those running pipelines of three or more concurrent projects — have started structuring design management differently. Instead of a permanent hire sitting inside the business, they're engaging specialist design management resources on a project basis, scaled to programme phase and scope complexity.
What this looks like practically:
At DA and early DD, engagement is light: governance setup, consultant scope review, programme establishment. A day or two a week across the project.
At CC and IFC, engagement intensifies: full coordination management, authority liaison, compliance pathway management, RFI and technical query tracking. This is where the specialist hours are deployed, not spread thin across the year.
At construction phase, the model pivots again: embedded support for superintendent functions, site-level design queries, variation management, and the documentation trail that OC depends on.
This isn't about replacing your internal team. On larger businesses with multiple projects, it's about extending capability at the right phase without the permanent overhead. Your in-house project director stays in the commercial driver's seat. The specialist resource runs the design programme.
The commercial result is straightforward: you're paying for design management expertise when the project needs it, not maintaining it at full cost when it doesn't.
The risk you're carrying by not changing the model
The design management staffing gap isn't just a cost question. It's a risk question.
Under the DBP Act, the builder carries significant exposure where design compliance isn't properly managed. Regulated designs that aren't properly declared, performance solutions that aren't properly documented, critical coordination failures that create latent defects — these don't just produce delays. In a post-Mascot Towers, post-Opal Tower environment, they produce NCAT proceedings, licence conditions, and project team liability that follows individuals, not just entities.
An under-resourced design management function isn't a controllable risk. It's an uncontrolled one.
The conclusion most builders won't say out loud
The full-time design manager made sense when construction was simpler, pipelines were predictable, and compliance was manageable. None of those conditions still apply at scale.
The builders getting ahead of this aren't making a radical move. They're making a commercial one: matching design management resource to the actual shape of the work, rather than the shape of an org chart.
Fixed overhead doesn't equal capability. And in a regulatory environment that's only getting more demanding, capability is what protects the project — and the business behind it.
