Optimizing alternative delivery through virtual design

How technology can strengthen collaboration, surface risk and support more predictable project outcomes

By Marc Whitmore, PE | HNTB

Alternative delivery is creating exciting new opportunities for transportation agencies to advance complex programs with greater efficiency and confidence. By aligning owners, designers and contractors around a common set of project goals, more sophisticated virtual models are great tools helping project teams evaluate risk proactively, improve constructability and make rapid decisions with a fuller understanding of cost, schedule and long-term project outcomes.

Digital technologies are helping agencies realize more of that promise. Virtual design and construction, model-based coordination and shared data environments provide an option to project teams wanting a clearer view of how disciplines, decisions and risks intersect throughout the delivery lifecycle. When these tools are aligned with clear project goals and delivery expectations from the outset, they can help to strengthen alternative delivery by facilitating collaboration, resolving complexity sooner and advancing projects with greater certainty.

How technology enables alternative delivery

In alternative delivery environments, integrating virtual design and construction early can strengthen the process itself — helping teams evaluate complexity sooner, coordinate decisions more effectively and use the model’s collaborative structure to its fullest advantage. This can support successful alternative delivery in several key ways:

• Earlier visibility into interdisciplinary complexity. Transportation projects bring together roadway, drainage, structures, utilities, traffic and other technical disciplines, each advancing essential components of the work. Three-dimensional model coordination and clash detection help teams understand how those elements interact before issues reach the field, creating a clearer picture of the project as a whole.
• Faster movement from issue identification to resolution. Visual review tools such as Autodesk Navisworks and Bently Navigator help teams identify surface conflicts earlier and coordinate a solution around them more quickly. Rather than spending valuable time interpreting drawings or developing one-off exhibits to explain an issue, teams can see the condition in context and focus sooner on the path forward.
• Clearer communication across integrated teams. Virtual design and construction creates a shared visual language that helps participants understand design intent, emerging concerns and potential impacts with greater consistency. This can reduce friction in decision-making and strengthen the collaborative culture these delivery models foster.
• Greater flexibility for innovation. Owners are increasingly creating the conditions for technology to add value by defining digital expectations while allowing delivery teams flexibility in how they meet them. This balance helps establish accountability without constraining the creativity and problem-solving that alternative delivery is designed to unlock.

Strategies for impact

Virtual design and construction delivers the greatest value when it is built into the alternative delivery workflow from the outset. Agencies are finding success when they establish clear expectations for how technology will support collaboration, inform decisions and help teams address complexity earlier in the process.

Key strategies include:

• Define the purpose of digital requirements early. Virtual design requirements are most effective when project teams understand what information is needed, when it should be exchanged and how it will support coordination, risk management and decision-making. Clear expectations at the outset allow digital practices to be incorporated into the delivery workflow rather than added later as a separate workstream.
• Build connected information practices. Alternative delivery projects involve a significant flow of information among owners, designers, contractors and other partners. Establishing reliable practices for exchanging agreed-upon information at the right cadence helps teams maintain alignment, even when different organizations operate within their own systems and workflows.
• Scale the approach to project complexity. The benefits of digital technologies are not limited to the largest or most visible programs. The technologies themselves can be applied across a range of project sizes, but the supporting structure should match the complexity of the work. Larger programs may warrant dedicated virtual design roles, while smaller efforts may benefit from a more targeted approach.
• Equip people to translate information into action. Technology creates value when teams have the capacity to interpret data, facilitate coordination and use digital insights to guide decisions. As agencies expand the use of these tools, training staff, identifying project champions and aligning workflows and team responsibilities with digital expectations can help ensure technology supports project execution in meaningful ways.

Many owners are already embracing these practices, recognizing that technology can be a powerful enabler of alternative delivery when it is connected to a clear delivery vision. By setting thoughtful expectations and allowing teams the flexibility to innovate within them, agencies can create stronger conditions for collaboration, coordination and project success.

Positioning alternative delivery for the future

Alternative delivery will continue to evolve as agencies manage increasingly complex transportation needs, compressed timelines and heightened expectations for performance. Virtual design and construction will play an important role in that evolution, helping project teams collaborate with greater precision, understand risk sooner and make more informed decisions throughout the delivery process.

Looking ahead, agencies that align digital practices with their alternative delivery goals will be well positioned to advance a more connected, responsive and confident approach to project delivery.
