Over the course of my career in procurement across large infrastructure programs, I’ve seen delivery models evolve in a meaningful way. One of the most significant changes has been the rise of design-build delivery. Working in environments like the Metropolitan Transportation Authority and the Metro-North Railroad, I’ve seen firsthand how this model is reshaping how projects are planned, sourced, and executed.
Traditional design-bid-build approaches were very structured. Design first, then bid, then build. That separation created clarity, but it also created distance between the people designing the work and the people building it. Design-build changes that dynamic by bringing those functions closer together under one coordinated effort. That shift has a direct impact on procurement strategy, contract management, and risk allocation.
Procurement Becomes More Integrated
In a design-build model, procurement is no longer just about issuing a bid and selecting the lowest responsible vendor. It becomes part of a much more integrated process where design decisions, construction methods, and cost considerations are all happening in parallel.
At Turner Construction Company, this integration is especially important. Procurement teams are not operating in isolation. They are working alongside engineers, designers, and project managers from the beginning. That early involvement helps shape scope in a way that is more realistic, more buildable, and more aligned with budget and schedule expectations.
This changes the role of procurement from being transactional to being collaborative and strategic. Instead of reacting to completed designs, procurement professionals are helping influence how those designs take shape in the first place.
Faster Delivery, But Greater Coordination Required
One of the biggest advantages of design-build is speed. By overlapping design and construction phases, projects can move forward more quickly than traditional models allow. In large infrastructure environments, that speed can be a major benefit, especially when public demand for improvements is high.
However, speed comes with a tradeoff. It requires a much higher level of coordination. When design and construction are happening at the same time, decisions must be made quickly and with accurate information. Any breakdown in communication can have immediate consequences for cost and schedule.
In my experience working on capital programs within the MTA system, coordination is the difference between smooth execution and constant adjustment. Design-build does not reduce complexity. It compresses it. That compression means procurement teams must be more engaged and more responsive throughout the entire project lifecycle.
Risk Shifts, It Does Not Disappear
One of the most important changes that comes with design-build delivery is how risk is allocated. In traditional models, risk is often split between the owner and the contractor in a more segmented way. In design-build, many of those risks are consolidated within a single contract structure.
This does not eliminate risk. It shifts it. The design-build entity takes on greater responsibility for both design accuracy and construction execution. That means procurement must be extremely careful in how contracts are structured, how performance expectations are defined, and how accountability is maintained.
From a procurement perspective, this requires a deeper understanding of technical requirements. It is not enough to focus on commercial terms. You also have to understand how design decisions can impact construction feasibility and long-term performance.
Collaboration Replaces Silos
One of the most noticeable differences in design-build delivery is the breakdown of traditional silos. Instead of separate teams working independently, you have integrated teams working toward a shared outcome.
That sounds simple, but in practice it requires a cultural shift. Procurement teams, engineers, designers, and contractors all have to operate with a higher level of transparency and trust. Information sharing becomes essential, not optional.
When done well, this collaboration leads to better problem solving. Issues are identified earlier, and solutions are developed faster. Instead of passing problems from one phase to another, teams work through them together in real time.
In large transit environments like Metro-North Railroad, that kind of collaboration is critical. The scale and complexity of infrastructure programs leave very little room for disconnected decision-making.
Procurement Strategy Becomes More Forward-Looking
Design-build also changes how procurement strategy is developed. Instead of focusing primarily on final specifications, procurement teams must think ahead about how early design decisions will impact cost, constructability, and lifecycle performance.
This forward-looking approach requires a broader skill set. Procurement professionals need to understand not just pricing and contracts, but also sequencing, engineering constraints, and operational impacts.
At organizations like the Metropolitan Transportation Authority, this shift has been especially important in capital programs where long-term infrastructure performance matters as much as initial delivery. Decisions made early in design can influence maintenance costs, reliability, and service quality for decades.
That is why procurement in a design-build environment is not just about selecting vendors. It is about shaping outcomes.
Strong Governance Is Still Essential
Even though design-build encourages flexibility and collaboration, strong governance is still essential. In fact, it becomes even more important. With multiple disciplines working together, there must be clear structures in place to ensure accountability and consistency.
Governance defines how decisions are approved, how changes are managed, and how performance is measured. Without it, the speed and flexibility of design-build can lead to confusion or misalignment.
Procurement plays a key role in maintaining that structure. Contracts, reporting systems, and performance metrics all help ensure that the project stays aligned with organizational goals while still allowing enough flexibility for innovation and adjustment.
Final Thoughts
Design-build delivery models are changing construction procurement in a fundamental way. They are making the process more integrated, more collaborative, and more responsive to real-world conditions.
From my experience working in large infrastructure environments, including the Turner Construction Company and transit systems like the Metropolitan Transportation Authority, I have seen how powerful this shift can be when it is managed well.
But it is not a simple improvement over traditional models. It is a different way of working entirely. It requires stronger communication, deeper technical understanding, and more active involvement from procurement teams throughout the project lifecycle.
At its best, design-build does more than accelerate delivery. It brings people together earlier, aligns goals more clearly, and ultimately leads to better outcomes for complex infrastructure programs.
