Two section bridge with 44.5 m arcs, 14.55 m wide and a height of 3 m. Two 0.9 m wide and 2.5 m high rectangular beams constituted the load supporting structures. The bridge passes over the Kwisa River where the river width is 18 m.
The Vertical PRIMO Formwork system complemented by the components of the 12/20 DSD universal beam system facilitated the construction of the bridge abutments and the columns, which required a characteristic shape.
The special adjustable DSD 12/20 stiffeners were used when making the bevels of the abutment.
Due to their atypical and complicated shapes, the columns were made in two phases. Vertical PRIMO Formwork complemented by plates specifically adjusted to the shape of the elements was used in the first phase. In the second phase, an individual solution based on the DSD beams Formwork stiffeners was used.
Thanks to the load capacity of the T-60 Falsework, it was possible to support the structure with only two rows of framework under the frames, getting maximum performance from the material used.
Likewise, with the TAC 1200 Composite Beams, it was possible to avoid using the intermediate support. The distance between arcs was 24 m. The solutions aided in reducing costs and execution time, once again increasing job performance.
Vertical PRIMO Formwork was used for the frames.
On top of all the aforementioned, the construction project was carried out on unfavorable terrain. Nonetheless, thanks to its broad experience already obtained in executing construction projects with similar characteristics, ULMA Construcción was able to provide the appropriate solution to enable executing the Architectural “work”.
