Fabrication and installation of bridge and suspended metal structures.
Production and installation of bridge structure elements.
Task
An overpass over a live road: a steel pier and span that had to be fabricated and erected without stopping the traffic below. Work on the pier and at the span bearing had to be carried out from scaffolding over the carriageway without interrupting traffic.
Solution
Pier and span elements were fabricated at our own facility to shop drawings, with the anticorrosion coating applied in the shop, so the structures arrived on site ready to lift. Erection was carried out by our own crews: the pier was set and aligned, the span lifted by crane and brought onto the bearing. The bearing joint was welded up and closed from scaffolding built around the pier, which allowed work above the road without closing it to traffic. Every lift over the carriageway was planned as a separate stage with its own rigging scheme.
