One of PB's early design/build projects was the Detroit-Windsor Tunnel—the first subaqueous tunnel to connect two countries, the U.S. and Canada. Since then, we have participated in over 800 design/build projects around the world, with services including:

• Environmental planning
• Concept/preliminary design
• Bid package preparation and evaluation
• Design review/approval
• Shop drawing review
• Construction inspection
• Acceptance
• Operations and maintenance planning
• Operations

Serving as single point of contact

Most of our work in design/build has been as owner's representative, acting as the liaison between the owner and multiple stakeholders, consultants and contractors. Our involvement can range from general engineering consultant, responsible for developing specific design/build packages, to program management or project oversight, responsible for extending into the procurement, construction and operating phases.

In every collaboration, we leverage our extensive technical knowledge and expertise to ensure that the owner gains full benefit from the design/build approach.

PB has completed 12 turnkey design/build projects where our constructors held the contract and assumed the construction risk—alone or in joint venture with select contractors. PB has taken an at-risk position in design/build in the markets of power, telecom, aviation and automotive.
