Bridge launching

Incremental bridge launching method

The incremental bridge launching method involves building an entire bridge deck from only one abutment of the bridge. The launching method performs a step-by-step procedure and different sections of the bridge are assembled by pushing the structure outwards from an abutment towards the pier. For these operations, we usually use our T-15 strand jacks.

The incremental bridge launching method is efficient and convenient.

• It enables rapid construction.
• It uses less space with its superstructure assembly.
• It causes minimal disturbance to surroundings including environmentally sensitive areas.
• It provides increased worker safety since erection work is conducted at a lower elevation.
• It can be used for bridge decks with lengths greater than 250m.
