Work Methods and Engineering Documentation

A demolition is a construction run backwards. We write the sequence, determine what must be supported before each removal, and verify stability in the intermediate states — the ones nobody calculated in the original design.

Erection procedures, temporary supports required at each stage, bridge girder placement plans and stripping methods. Edge-girder rotation analysis addresses the torsion that appears when the deck is poured asymmetrically.

The paperwork that goes with the method: design calculations, temporary works drawings, shop sketches, certificates of conformity. This is what is handed to the resident engineer, the owner or the inspector, and what stays on file once the work is done.
