Gabriel Neves, Tekla bridge structures manager, recalls meeting Sigmund Reinsborg Log, head of section/head of verification and approval for the Department of Structures, an authoritative body of Norway’s Directorate of Public Roads.
When the Norwegian Public Roads Administration asked the design-build team of Sweco, PNC, Armando Rito Engenharia and Isachsen to deliver a 643-meter-long concrete box-girder bridge completely in 3D, designers with Armando Rito were initially a bit skeptical.
The Grist Mill Bridge, a 75-ft single span bridge in Hampden, Maine, is the first in the nation to use composite tub girders with no concrete reinforcement in the superstructure.
Permanent floating bridges are essentially boutique structures that only make sense for certain rare kinds of sites: unusually deep bodies of water and/or bodies of water with very soft bottoms, where piers are impractical.

Progressive Design-Build is reshaping large infrastructure projects by addressing key issues with the traditional Design-Build approach. We'll explore how PDB fosters collaboration between owners, design-builders, and design teams to develop a well-defined scope and budget, plus minimizes cost overruns and reduces liability claims.
