IBC 18-21: Queensferry Crossing – quality and value in design-build

Matthew Carter, Arup, New York, NY; Richard Hornby, Arup, Leeds, United Kingdom; Naeem Hussain, Arup, Kowloon Tong, Hong Kong, China; Iain Murray, Jacobs, Edinburgh, United Kingdom

The Queensferry Crossing in Scotland was recently opened at an outturn cost of $1.8Bn, compared to the original forecast of $4.4Bn. The 1.6 mile long cable stayed bridge, with back to back main spans of 2,130ft each, is highly acclaimed as being of outstanding quality and will stand alongside two historic bridges. Key decisions in the procurement, including up-front investment by the owner, led to price certainty, value for money and high-quality architecture.


IBC 18-22: Bonner Bridge – Innovation, Economy, Durability in a Challenging Environment

Domenic Coletti, P.E., Elizabeth Howey, LG, P.E., and John Jamison, AICP, HDR, Raleigh, NC; R. Dominick Amico, P.E., HDR, Charlotte, NC; Nicholas Burdette, P.E., HDR, Pittsburgh, PA; Phil Dompe, P.E., INTERA, Inc., St. Augustine, FL; Mohit Garg, P.E., HDR, Tampa, FL

The design-build replacement of the Herbert C. Bonner Bridge, which carries NC Highway 12 over Oregon Inlet, required a 100-year service life, design for up to 84’ of scour, and minimal environmental impacts. The associated design and construction challenges provided opportunities for innovation and creativity. The resulting 2.8 mile long bridge features extensive use of precast concrete for quality, durability, economy, and constructability, a first-of-its-kind driven pile foundation verification method, and innovative, environmentally-sensitive construction approaches.
