This is a project of a road flyover above a railway. The structure is divided
basically in three main parts: two abutments in reinforced concrete and
the flyover made of prestressed concrete. The total length of the project
is 365.80 m. The project is formed by two hyperstatic sections with three
spans of 45 m each.
SCIA Engineer
was used for calculation of the structure. This software
has a user-friendly interface and fulfills our main challenges for hyperstatic
precast flyovers.
Allplan Engineering
was used to produce drawings
of the project, and we obtained fast results of detailing and precision in
calculating material quantities.
The main challenges faced were the interferences found on site. As
the flyover is above a railway, interferences of electrical grids had to
be considered, imposing a small template for construction and less
expropriation area. Another challenge was that the railway could not be
stopped for construction of the flyover, so it was necessary to calculate
steel shorings.
The project was finalized on time, and by using Nemetschek Group
software we had great productivity in detailing and calculation.
