90 Category 2: Civil Structures 2 Railway EF-105 Flyover Jundiapeba - Mogi das Cruzes SP, Brazil AP SE Owner: DNIT - Departamento Nacional de Infraestrutura de Transportes Architect: Azambuja Engenharia e Geotecnia Ltda. General Contractor: Confidential Engineering Office: Azambuja Engenharia e Geotecnia Ltda. 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.
