On the Economy and Benefits of 3-D Design Method in Bridge Engineering

The paper examines the economy and benefits of 3-D design method in concrete bridge engineering. New 3-D CAD design tools and 3-D measurement methods were developed and tested in the several real bridge construction projects in Finland during 2001-2004. The paper describes these observations and suggests some conclusions for future developments as well as more expansive utilization especially in bridge construction in Finland. The next steps to be projected are also described.
