Executive Summary
Design & Build and Traditional procurement routes are often framed as a choice between speed and control. In reality, the decision is more nuanced.
Both routes can deliver strong outcomes. The issue is not which route is “better”, but whether it is being used at the right point, with the right level of information.
In the current market, procurement strategies are increasingly influenced by commercial structures, familiarity and perceived simplicity. As a result, projects are sometimes pushed towards Design & Build before the design and brief are sufficiently developed.
This can create a false sense of cost certainty and reduce the level of challenge at the stage where it matters most.
The key is to ensure that procurement strategy is driven by the needs of the project – supported by a clear brief, robust design development and independent advice.
Market context
Procurement strategy has always been a critical decision point in project delivery.
In today’s market, that decision is being influenced by more than just the project itself. Roles are overlapping, commercial models are evolving, and the same parties often sit across multiple stages of the lifecycle.
Individually, none of this is unusual. Taken together, it starts to shape outcomes.
At the same time, there has been a gradual shift in capability across parts of the industry. Traditional procurement routes (including Design-Bid-Build, Management Contracting and Construction Management) rely on strong upfront definition, coordination and informed client-side decision-making.
Where those skills or experience are less prevalent, teams naturally gravitate towards routes that feel more familiar or simpler to deliver.
In practice, this means procurement strategy is sometimes driven by what the team is comfortable with, rather than what the project actually requires.
Familiarity can reduce perceived risk in the short term, but it does not necessarily lead to better outcomes.
This is one of the reasons we are seeing Design & Build being adopted earlier in the process.
Traditional procurement: control and clarity
Traditional procurement gives the client control over the design.
It allows the design to be properly developed, coordinated and tested before construction begins. That typically leads to a clearer definition of scope, better alignment with the brief and a stronger basis for tendering.
From a cost perspective, it also allows for more robust cost planning and reduces the level of uncertainty carried into procurement.
The trade-off is time. Design programmes are longer, and it requires a team that can manage and make decisions through the process.
Design & Build: integration and speed
Design & Build brings design and construction together under a single point of responsibility.
Used well, it can deliver programme efficiencies, earlier contractor input and a more streamlined delivery process.
However, it only works properly when the brief and performance requirements are clearly defined at the point of contractor engagement.
If they are not, risk is transferred to the contractor in a way that is not always fully understood. The price may look certain, but the underlying assumptions are not.
That gap is where problems tend to emerge.
Where it goes wrong
Issues arise when Design & Build is used too early.
Typically, that means:
- Design information is not fully developed or coordinated
- Performance requirements are not clearly defined
- Cost certainty is presented earlier than it genuinely exists
- There is limited challenge at the stage where it would have the greatest impact
On paper, the project looks like it is moving quickly. In reality, uncertainty has just been pushed further down the line.
It usually comes back later through change, re-pricing or compromise.
The importance of a well-defined brief
Regardless of procurement route, the quality of the brief is critical.
It defines what the project is trying to achieve and sets the parameters for design, cost and delivery.
Without a clear brief, it is difficult to compare contractor proposals or ensure alignment between expectation and outcome.
Example
I worked on a Design & Build project where the client asked for a review of the contractor’s price shortly before contract.
The visuals were strong, but key elements – including acoustic and environmental performance – had not been properly defined. The client didn’t fully understand what they were buying.
The result was a late-stage renegotiation of the contract sum.
Avoidable, but not uncommon.
The role of independent advice
This is where independent advice makes the difference.
An experienced, independent team will:
- Define the brief and performance requirements
- Align procurement strategy with project objectives
- Challenge assumptions at the right stage
- Ensure that cost certainty is based on real information
That independence matters.
Where commercial structures influence decision-making, there is a risk that procurement routes are selected based on what suits the ecosystem around the project, rather than the project itself.
Independent advice brings the focus back to what actually matters.
Choosing the right approach
Both Traditional and Design & Build can deliver successful projects.
The key is timing and application.
Traditional procurement works well where control, clarity and quality are the priority.
Design & Build works well where programme is critical, provided the brief is properly defined.
In many cases, the best outcome sits somewhere between the two. Develop the design to the right level, then bring in the contractor at the point where they can add value without inheriting unnecessary uncertainty.
Conclusion
Design & Build is not the issue. Traditional procurement is not the answer.
The risk sits in how and when each route is used.
When procurement strategy is driven by the needs of the project, supported by a clear brief and independent advice, both routes can work.
When it is driven by familiarity, perceived simplicity or wider commercial pressures, the consequences tend to surface later – when they are harder and more expensive to address.
