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.

Services for the realisation stage include:

• Construction management
• Detailed planning of the construction works
• Supervision of prefabrication of bridge elements
• Erection supervision
• Calculation of precamber
• Step-by-step calculation of erection stages
• Calculation of the effects of built-in stresses and deformations
• Control and adjustment of geometry and forces of cable supported bridges.
