Degree of Freedom has designed a 370m concrete post-tensioned bridge for railway traffic starting from the development of design alternatives through to the detailed design, including 5D BIM.
The New Quisi Bridge is a concrete railway bridge over the Quisi ravine, as an alternative to the existing 100-year old bridge. It consists of 8 spans, two end spans of 35m and six 50m midspans giving a total length of 370m. The superstructure is a continuous post-tensioned box girder with a curved surface supported by three types of concrete pier. Two small piers with a variable curved section, a V-shaped piler acting as fixed point and four high piers with a variable diamond cross section and conical capital. The abutments are formed of concrete with a curved and variable surface.
Structural engineering during the study of alternatives, preliminary and detailed design, seismic study, erection sequence, budget, project documentation, BIM modelling, management and quality control.
