BANDI provides construction engineering services for long-span bridges such as suspension and cable-stayed bridges. This service includes geometry control for the construction of cables, towers, and stiffening girders for cable-stayed and suspension bridges, as well as the design of major temporary structures for bridge construction.

For suspension cables, we support the planning and design of cable erection equipment for the anchorage part and cable erection equipment for the tower. We also provide services such as selecting the optimal catwalk system for the main cable erection and controlling the shape of the main cable.

For towers, we provide planning of temporary structures such as temporary struts and crossbeam scaffolding trusses for tower construction, and shape management services for towers during tower construction.

For suspension bridge girders, we provide services such as selecting the optimal construction method by comparing erection methods for girders, lifting methods for girders, and analyzing buffeting against wind, and we also provide girder temporary structure design and girder geometry control services for each stage of construction.

BANDI's engineers have experience in CE for the 3rd Bosporus Bridge in Turkiye, and are currently working on CE for the Chacao Bridge in Chile and the New Sotra Bridge in Norway.
