Supervision of prefabrication and erection 

COWI has within the group engineers with field experience from prefabrication and erection of bridges.

During the erection of a bridge each step of the erection needs to be controlled carefully to obtain the required distribution of forces and geometry.

With our in-house developed computer programme COWI can provide Step-by-Step calculations for the erection of bridges.

The effects of cast-in stresses and deformations, creep and shrinkage of concrete and construction tolerances are included and assessed with the programme.
