The Barriers to Capacity Sharing in Construction
The concept of capacity sharing in construction is relatively straightforward.
Where manufacturing capability exists but is underutilised, and where demand is unevenly distributed, sharing capacity offers a logical way to improve efficiency. It has the potential to reduce downtime, stabilise output and make better use of existing resources.
However, despite these potential benefits, capacity sharing remains limited in practice.
The reason is not a lack of technical feasibility. It is the presence of structural, commercial and cultural barriers that make implementation challenging.
Understanding these barriers is essential if capacity sharing is to move beyond theory.
Commercial Risk and Competitive Tension
One of the most significant barriers is commercial.
Construction operates within a competitive environment. Organisations invest in facilities, processes and systems with the expectation of securing and delivering their own work. Capacity is often viewed as a competitive advantage rather than a shared resource.
Allowing another organisation to use that capacity introduces risk.
This can include:
• Concerns over margin dilution
• Uncertainty around pricing structures
• Potential exposure to delivery risk from third parties
• Reduced control over how production is managed
There is also the issue of competition.
Manufacturers may be reluctant to collaborate with organisations they are directly competing with for work. Sharing capacity in this context can feel counterintuitive, even where it may improve overall system efficiency.
Contractual Complexity
Capacity sharing introduces additional layers of contractual complexity.
Traditional construction contracts are typically structured around a clear chain of responsibility. A single contractor or manufacturer is accountable for delivery.
Sharing capacity disrupts this model.
Questions arise around:
• Who is responsible for quality assurance
• How liability is allocated across multiple parties
• How delays or defects are managed
• How performance is measured
Without clear contractual frameworks, these issues create uncertainty.
This uncertainty increases perceived risk, which in turn discourages participation.
The Competition and Markets Authority has highlighted that complexity and lack of transparency in construction contracting can act as barriers to more efficient market operation

While not specific to capacity sharing, this observation reflects the broader challenge of introducing more collaborative models into existing structures.
Intellectual Property and Process Protection
Another barrier relates to intellectual property.
Manufacturers invest in developing proprietary systems, processes and product designs. These may include specific methods of assembly, component configurations or digital workflows.
Sharing capacity can raise concerns about:
• Protecting proprietary information
• Maintaining differentiation in the market
• Avoiding unintended knowledge transfer
Even where formal agreements are in place, the perceived risk of losing competitive advantage can limit willingness to engage.
Lack of Standardisation
Capacity sharing is easier where production processes are standardised.
In reality, the MMC sector includes a wide range of systems, platforms and specifications. Not all components are interchangeable, and not all factories are configured to produce the same outputs.
This creates practical constraints.
For example:
• A facility may not be set up to manufacture a specific system
• Differences in design standards may require rework
• Variations in quality assurance processes may complicate integration
Without a degree of standardisation, the ability to transfer work between facilities is limited.
Data Fragmentation and Limited Visibility
Effective capacity sharing depends on visibility.
Organisations need to know where capacity exists, what it can produce and when it is available. At present, this information is rarely shared in a structured or accessible way.
Data tends to be:
• Held internally rather than shared
• Inconsistent in format and detail
• Not updated in real time
This lack of visibility makes it difficult to match capacity with demand, even where both exist.
Without reliable data, capacity sharing cannot be coordinated effectively.
Misaligned Incentives
Another challenge lies in how incentives are structured.
Individual organisations are typically incentivised to maximise their own performance. This includes securing work, maintaining margins and managing risk.
Capacity sharing, by contrast, requires a degree of collective optimisation.
This can create tension.
For example:
• An organisation may prioritise retaining capacity for potential future work rather than sharing it in the short term
• Short-term commercial considerations may outweigh longer-term system benefits
• Clients may prioritise lowest cost over system efficiency
Without aligned incentives, capacity sharing is unlikely to scale.
Cultural Resistance
Beyond structural and commercial factors, there is also a cultural dimension.
Construction has traditionally operated in a fragmented and competitive way. Collaboration exists, but often within defined project boundaries.
Capacity sharing requires a broader form of collaboration that extends beyond individual projects and organisations.
This can be challenging.
It requires:
• Trust between organisations
• Willingness to share information
• Openness to new ways of working
These are not purely technical changes. They represent a shift in mindset.
The Role of Clients and Policy
While many barriers sit within the supply chain, clients and policymakers also have a role to play.
Procurement approaches can either enable or constrain capacity sharing.
Project-based procurement, where each scheme is delivered independently, limits opportunities for coordination. Programme-based approaches, where multiple projects are aligned, provide greater flexibility.
Policy can also influence behaviour.
Encouraging transparency, supporting data sharing initiatives and promoting collaborative delivery models can help to reduce some of the barriers identified.
From Barrier to Opportunity
While the barriers to capacity sharing are significant, they are not insurmountable.
Many of them reflect how the industry is currently structured rather than inherent limitations of the concept itself.
Addressing these barriers requires:
• Clearer contractual frameworks
• Greater standardisation where appropriate
• Improved data visibility
• Alignment of incentives
• Cultural shift towards collaboration
These changes are not simple, but they are consistent with broader trends in construction towards integration and system-based delivery.
Conclusion
Capacity sharing offers a potential solution to underutilisation within the MMC sector. However, its implementation is constrained by a range of commercial, contractual and cultural barriers.
These barriers are not unique to capacity sharing. They reflect deeper structural characteristics of the construction industry.
Overcoming them will require coordinated effort across the sector, including clients, manufacturers and policymakers.
If these challenges can be addressed, capacity sharing has the potential to improve utilisation, reduce downtime and support more consistent delivery.
Until then, it will remain an idea with clear benefits, but limited practical application.
