The Real Culprit: Why Construction Keeps Overloading Itself — and How MMC, AI and Shared Capacity Can Finally Break the Cycle

By Same Stacey - A7C Limited

1. Unlocking MMC Capacity: The Hidden Inefficiency We Can No Longer Ignore

From Unlocking MMC Capacity, the evidence is stark:

• MMC factories are running at just 40–60% utilisation — described by industry as “the single biggest barrier to scaling up MMC and industrialised construction.”

• This isn’t a skills problem. It’s a coordination problem.

• As the report states: “Unlocking downtime unlocks delivery. Unlocking delivery unlocks homes.”

We already have the factories, the systems and the skills. What we lack is the ability to connect demand to capacity in a predictable, stable way.

2. Downtime Workshop & Miro Synthesis: Downtime Starts Upstream

The Downtime Workshop & Miro Synthesis report reinforces the same message:

• Downtime is a demand‑side failure, driven by slow planning, complex procurement and lumpy pipelines — not factory capability.

• Factories report 10–25% persistent under‑utilised capacity, even as the UK faces urgent housing need.

• Participants were clear: “Downtime starts upstream.”

• And critically: the sector is ready for shared capacity, but government must back standard evidence, fast‑track routes and a national pilot.

The conclusion is unavoidable: We are under‑delivering not because we lack capacity, but because we fail to coordinate the capacity we already have.

And overloaded systems don’t get fixed by working harder. They get fixed by redesigning how the system works.

3. The Cognitive Overload Problem: Why the System Fails Even When People Don’t

Construction has become a system that demands more cognitive processing than humans can realistically provide:

• Thousands of documents

• Constant design changes

• Fragmented procurement routes

• Conflicting evidence requirements

• Volatile pipelines

• Planning uncertainty

• Spreadsheet‑driven programme management

This is not a human‑performance problem. It is a system‑design problem.

And overloaded systems don’t get fixed by working harder. They get fixed by redesigning how the system works.

4. The Path Forward: Industrialised Construction + AI + Shared Capacity

To break the cycle, we need three things working together:

Industrialised Construction

Predictable, repeatable building blocks that reduce complexity at source.

AI

The processing power to handle the cognitive load — the data, the interfaces, the evidence packs, the sequencing — so humans can focus on judgement, not admin.

A Shared Capacity Platform

The coordination mechanism the sector has been missing — matching real projects to real factory availability, stabilising pipelines, and turning downtime into delivery.

This is how we turn unused factory hours into real homes, real jobs and real progress — not by pushing people harder, but by building a delivery model that finally matches the scale of the challenge.

5. Where This Conversation Continues: The BOPAS Forum, 11 June

BOPAS FORUM & HADLEY FRAME FACTORY TOUR - BOPAS

These findings aren’t theoretical. They are shaping the next phase of sector action.

At the BOPAS Forum on 11 June, we’ll be taking this conversation out of theory and into practice. The agenda is built around one central question: how do we move Industrialised Construction from concept to scaled delivery in a system that is currently overloaded?

Our speakers bring perspectives from every part of that journey:

• Oliver Novakovic MCABE CBuildEng  Barratt Developments — on how major housebuilders are industrialising delivery and what it takes to embed repeatability at scale.

• Steve Chesters  Hadley Group — on manufacturing discipline, systemisation and the realities of factory‑to‑site integration.

• Mike Ormesher OTTERSBROOK LIMITED — on the commercial and operational pressures facing MMC suppliers and why stable pipelines matter.

• Ali M. Saad, PhD Loughborough University — on the research, data and performance evidence needed to build confidence in MMC.

• Eva Magnisali DataForm Lab — on how automation and AI can transform design, sequencing and production.

Together, they’ll explore the same themes highlighted in our reports: the cognitive overload in today’s delivery model, the chronic under‑utilisation of MMC capacity, and the need for shared evidence, shared standards and shared infrastructure to unlock national scale.

If we want to build more, faster and with confidence, we must stop treating complexity as inevitable — and start designing it out.

The future of delivery is industrialised. The future of decision‑making is augmented. The future of coordination is shared.

And the future of MMC depends on our ability to bring all three together — which is exactly what the BOPAS Forum on 11 June is designed to do.
