Alternative Delivery

Alternative design contracts for transportation services shift away from the traditional design-bid-build approach by integrating design and construction responsibilities into a single coordinated team. These delivery methods, such as design-build or construction manager/general contractor, can improve schedule, cost control, and collaboration while allowing agencies to accelerate project delivery and manage risk more effectively.

Choosing the right delivery method can be as important as the design itself. DLZ helps agencies evaluate and execute across the full range of alternative approaches – from design-build and progressive design-build to public-private partnerships – bringing the collaborative discipline and technical depth that complex, accelerated projects require.

Design-Build

Design-build delivery integrates design and construction within one team to streamline communication and decision-making. DLZ’s approach helps accelerate schedules, improve cost certainty, and reduce risk by addressing constructability early in the process.

Progressive Design-Build

Progressive design-build allows projects to advance collaboratively while design and cost validation occur in parallel. This method supports transparency, informed decision-making, and risk identification before construction commitments are finalized.

Public-Private-Partnership (P3)

Public-private partnerships leverage private sector participation to deliver complex transportation projects. By aligning responsibilities, resources, and long-term performance goals, P3 delivery can improve efficiency, innovation, and lifecycle value.
