Construction will not capture the full value of AI, BIM, automation or offsite manufacturing by buying more software and equipment. The operating model has to change with them: design and delivery must work as one system, project data must remain usable across company boundaries, and firms need enough internal capability to control quality, skills and execution.
That is the central argument made by Paul Ruddick, founder and chairman of Reds10, in a Building comment published on 25 July 2025. His experience is a useful case for examining the issue, not proof that one structure suits every contractor. Independent UK evidence points to a real productivity and coordination problem, while also showing that subcontracting and digital methods can deliver benefits when they are organised well.

Ruddick’s proposition is broader than digital transformation in the usual sense. He argues that industrialising construction requires reform of the main-contractor business model, including the way projects are designed, procured, staffed and controlled. In his words, “To industrialise construction, the industry will need to undergo systemic change – starting with reform of the main contractor business model.”
Four changes sit at the centre of that diagnosis:
- Design-led delivery: buildability, manufacturing constraints and installation requirements enter design decisions early, rather than being discovered after procurement.
- Integrated execution: designers, contractors and specialist manufacturers share workflows and information before choices become expensive to reverse.
- Internal capability: a firm retains enough design, engineering, data, manufacturing and site knowledge to direct the system instead of treating every capability as a detached purchase.
- Technology across functions: digital tools are embedded in estimating, design, production, logistics, commissioning and operations, not isolated in a specialist team.
Ruddick summarises the last point as: “Technology must be embedded across the entire business, not siloed in specialist teams.” This is an operating-model claim, not a promise of a particular percentage improvement.

Why technology has not automatically lifted construction productivity
Office for National Statistics analysis published in 2021 found that construction productivity levels remained below the UK average through 2020. Labour productivity did grow slightly faster than the whole economy after the 2008 downturn, but the sector’s long-term performance still contrasted sharply with other industries.
A UK government study on modern methods of construction reported that industrial productivity rose by about 25% and automotive productivity by about 45% over a 20-year period, while construction productivity was virtually flat over the same broad period. These are contextual comparisons from that study, not current annual growth rates or a forecast for any individual contractor.

Construction output includes changing project types, temporary organisations and quality improvements that may not be fully captured by conventional productivity measures. ONS also warns that industry boundaries affect the numbers. A weak productivity statistic therefore identifies a problem to investigate, not a simple verdict that every construction activity is inefficient.
Fragmentation is a trade-off, not an automatic failure
ONS reported that more than 50% of construction intermediate consumption was subcontracting expense in its 2021 analysis. Subcontracting can provide specialist expertise, flexibility and competition. It can also create extra interfaces, duplicated information, delayed decisions and communication costs when responsibilities and data are poorly coordinated.
The practical question is therefore not whether subcontractors should disappear. It is who controls design intent, interfaces, quality information and decisions when many organisations contribute to one asset. A system that preserves specialist competition while making interfaces explicit may outperform both a completely integrated firm and an unmanaged chain of contracts.
How technology creates value when the workflow is connected
Digital tools create value through the decisions and handoffs they improve. A model, application or automated machine is useful only when its outputs are accepted by the next person or process without being re-entered, interpreted from scratch or corrected late.
BIM as a shared information structure
Building information modelling can connect geometry, specifications, quantities, approvals and asset information. Its benefit depends on agreed naming, classification, responsibility and exchange rules. If each organisation maintains an incompatible model, BIM becomes another set of files to reconcile rather than a shared source of decisions.

Government research on volumetric modular construction, published in 2024, found evidence that BIM integration can support manufacturing productivity and that data exchange can connect stakeholders during procurement and commissioning. The same review said evidence across the entire project lifecycle remains limited. BIM can make a connected workflow possible; it does not establish a guaranteed project-wide productivity gain.
Automation and machine-readable production information
Ruddick describes Reds10’s experience of automating production information. On large projects, a process that once generated around 100 steel drawings produced thousands of individual files because each part could receive its own machine-readable drawing. He presents this as a company example, not an industry benchmark.
The example exposes a common misconception: automation does not remove information-management work. It can increase the volume, speed and complexity of outputs. Human reviewers still need to check that drawings are complete, coherent, correctly coordinated and suitable for fabrication. Automated generation should therefore include version control, exception handling, approval gates and a clear owner for final technical decisions.
Offsite manufacturing and industrialised production
Factory production can make repeatable work more measurable and enable earlier quality checks, but it shifts effort upstream. Design tolerances, interfaces, lifting points, transport limits, sequencing and site connections must be resolved before manufacture. The business needs reliable component data and a way to update that data when a design changes.
Ruddick says industrialisation required sustained investment in processes, people and design capability as well as manufacturing equipment, and that Reds10’s journey remains long term and unfinished. The lesson is that a factory is an outcome of process development, not a substitute for it.
Changing the main-contractor model
Ruddick argues that “The main contractor model needs to be led by design and not procurement to fully take advantage of AI, digital tools and industrialisation.” In a procurement-led pattern, design is progressively handed to others while packages are bought and coordinated. A design-led pattern treats buildability, manufacturing and operational requirements as inputs to design from the start.
| Decision area | Procurement-led pattern | Design-led, integrated pattern |
|---|---|---|
| Design and buildability | Buildability issues may surface after package scopes and prices are set. | Designers, constructors and specialists test buildability and manufacture early. |
| Specialist involvement | Manufacturers and trades often enter after key design decisions. | Relevant specialists contribute before interfaces and components are locked. |
| Capability location | Knowledge is distributed across contracts, with limited internal control. | The lead firm retains enough technical and delivery capability to direct the system. |
| Data flow | Information is exchanged at package boundaries and may be reformatted repeatedly. | Common structures, libraries and interfaces allow information to travel through design, manufacture and commissioning. |
| Commercial emphasis | Short-term package price and procurement timing dominate. | Total value includes design effort, production stability, quality, installation and operational information. |
This table describes analytical differences, not a validated ranking. A smaller contractor may use a network of trusted specialists effectively, while a large contractor may still suffer fragmentation inside a nominally integrated structure. Governance and incentives determine the result.

Build the foundations before scaling automation
Technology projects commonly fail because the underlying information and responsibilities are unclear. Before automating a high-volume process, establish:
- Data ownership: identify who creates, checks, approves, changes and archives each information type.
- Common structures: define naming, classification, units, revision status, attributes and permitted values for components and spaces.
- Interface contracts: specify what each system or supplier must provide, in which format, at what stage and with what validation.
- Component libraries: maintain controlled, approved objects that carry geometry, performance, fabrication and installation information.
- Skills and training: combine domain expertise with model management, data governance, automation and change-management capability.
- Quality assurance: test automated outputs against design intent and physical requirements, with traceable human approval.
Ruddick points to low-code tools and open application programming interfaces as making integration more accessible. They can reduce the effort needed to connect applications, but they do not remove the need to define data semantics, permissions, security, support and accountability.
He also cites pilots involving Autodesk Informed Design and Content Catalogue for managed component libraries and fabrication-ready elements. These are examples of the type of workflow being explored, not independent evidence that the products suit every organisation or deliver a measured productivity result.
A practical implementation sequence
Systemic change is easier to control when a firm moves from a defined problem to a repeatable workflow rather than launching an enterprise-wide software replacement.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitches- Choose one value stream. Select a repeated process such as a standardised façade panel, bathroom pod, steel frame or commissioning data handover. Define the delay, rework, safety or quality problem in measurable terms.
- Map the current handoffs. Record who makes each decision, which files are created, where information is re-entered and where approval waits occur. Include designers, procurement, manufacturers, site teams and the client.
- Set the information contract. Agree the minimum data, file formats, revision rules, responsibilities and acceptance tests needed at every handoff.
- Involve specialists before design freeze. Ask manufacturers and installers to test tolerances, access, sequencing, transport and maintenance while options can still change.
- Build or clean the component library. Start with a small controlled set. Retire duplicate objects and record the conditions under which each component is approved.
- Automate a bounded task. Generate a defined output, such as machine-readable fabrication drawings or a quantity schedule, and keep a human review gate.
- Pilot on a live project with baseline measures. Track design-change cycle time, rejected information, duplicate entry, manufacturing rework, site defects and handover completeness. Do not claim causation from one project without comparing conditions.
- Review contracts and incentives. Decide how early specialist input is paid for, who owns resulting data, how design responsibility is allocated and how savings or delays are shared.
- Scale only after proving repeatability. Document the workflow, train the next team and test whether the process works with different suppliers, project sizes and client requirements.
Making BIM and offsite construction work together
A connected modular workflow links design decisions to manufacture and then to commissioning. A typical sequence is:
- The design team defines performance requirements, spatial constraints and interfaces in a coordinated model.
- Manufacturers and installers review the model for fabrication tolerances, access, lifting, transport and connection details.
- Approved component data is issued through a controlled library, with revision status and responsibility visible to every participant.
- Production information is generated for machines and people, then checked against the model and approved drawings.
- Manufacture, inspection and delivery records are linked to the relevant component or assembly.
- Installation teams receive current instructions and record changes, defects and as-built information.
- Commissioning data is handed to the owner in a format that can support operation and maintenance.
The 2024 government review supports the potential of BIM and data exchange in manufacturing, procurement and commissioning. It also cautions that full-lifecycle evidence is limited, so organisations should measure their own outcomes rather than assume that a model automatically improves operations years after construction.
Investment, skills and time requirements
Systemic change requires more than licence or equipment expenditure. Budget for process design, data cleansing, library creation, integration, training, pilot disruption, independent checking and ongoing support. Ruddick’s account explicitly distinguishes buying manufacturing equipment from investing in the people, processes and design capability needed to use it.

Leadership must protect time for cross-functional teams. Designers need feedback from production and site; production needs stable, interpretable information; commercial teams need contracts that do not punish early collaboration; and site teams need a reliable way to report changes back into the information system.
Skills can be developed internally, hired, or shared with partners. The critical capability is not the title of a specialist but the ability to connect construction knowledge with data, automation and quality control. A company that outsources every digital decision may become dependent on systems it cannot properly specify or challenge.

Buying software before defining the process
Symptom: teams create parallel spreadsheets, exports and manual workarounds. Remedy: map the value stream and agree information responsibilities before selecting applications.
Automating inconsistent inputs
Symptom: automated drawings or schedules are produced quickly but contain missing attributes, conflicting revisions or incorrect interfaces. Remedy: clean the source data, set validation rules and retain human technical approval.
Introducing specialists too late
Symptom: a manufactured component is redesigned after procurement because tolerances, access or transport were not tested. Remedy: pay for specialist design input before the design is frozen.
Recommended Free Tools
Treating BIM as a file-delivery requirement
Symptom: models satisfy an exchange milestone but do not help manufacture, install or operate the asset. Remedy: define the decisions and downstream uses that each data field must support.
Assuming integration removes accountability
Symptom: teams cannot determine who approved a change or accepted a defect. Remedy: keep a responsibility matrix, approval history and escalation route even when systems are connected.

Scaling from an exceptional pilot
Symptom: a process works with one highly capable team but fails with different suppliers or a different project type. Remedy: test repeatability, document prerequisites and measure performance across several projects.
How to judge whether the change is working
Use a balanced set of leading and outcome measures. Leading measures show whether the new system is being used; outcome measures show whether it helps.
- Percentage of design packages reviewed by relevant specialists before release.
- Time from design change to an approved, production-ready revision.
- Number of manual data re-entries between design, procurement, manufacture and commissioning.
- Rejected drawings, model defects and late interface changes.
- Manufacturing rework, site rework and defects attributable to information errors.
- Completeness and usability of commissioning and handover data.
- Training completion and the proportion of work performed through the agreed workflow.
- Total cost and time of integration, support and quality assurance, not only software purchase price.
These measures should be interpreted with project complexity, design changes, supplier mix and quality improvements in mind. They can show whether a particular intervention is helping; they cannot by themselves prove that one organisational model is universally superior.
The policy and market context
The 2018 Construction Sector Deal identified inconsistent client demand and insufficient collaborative investment among designers, constructors and specialist manufacturers as barriers to wider adoption of modern methods and digitisation. That diagnosis explains why a capable contractor may still struggle to change: the commercial environment can reward lowest initial package price and late transfer of risk rather than early coordination.
The Department for Business, Innovation & Skills’ 2015 Digital Built Britain strategy placed BIM within a broader digital strategy for construction and the built environment. It is historical policy context, not evidence of current uptake or outcomes. The continuing issue is alignment between client requirements, contracts, supply-chain capability and the information needed throughout an asset’s life.
What the evidence supports—and what it does not
The available evidence supports a cautious conclusion. Construction has a persistent productivity challenge, fragmented delivery can create communication costs, and BIM, structured data and industrialised production offer plausible mechanisms for improving coordination and manufacturing. Ruddick’s Reds10 example illustrates the scale of process and information change that automation can create.

Firms should therefore treat systemic change as a managed operating experiment with explicit measures, not as a slogan or a guaranteed technology payback.
A decision checklist for construction leaders
- Can the business explain which design and delivery decisions are currently separated by procurement boundaries?
- Are designers, manufacturers and installers involved early enough to influence buildability?
- Who owns each critical data set, and can its revision history be traced?
- Do component libraries contain approved, fabrication-ready information rather than visual objects only?
- Can automated outputs be checked by accountable technical staff?
- Do contracts pay for early collaboration and define responsibility for shared information?
- Are training, integration and quality assurance funded alongside software and equipment?
- Is there a baseline and a pilot measure that can distinguish improvement from normal project variation?
- Can the process work with more than one project team and supplier network?
