As part of the 2050 Blumenau Program to improve Brazilian infrastructure, the BRL 25 million project required Sotepa to design an ecologically sustainable extension that would integrate into the landscape, accommodate the unstable soils, and promote public transportation, pedestrian traffic, and cyclists. To address these challenges, Sotepa relied on Bentley’s parametric modeling tools in PowerCivil for Brazil.
Sotepa designed the extension within right-of-way restrictions of a narrow river valley, with each lane following a distinct grade to minimize social and environmental impacts. Using PowerCivil for Brazil enabled Sotepa to perform complex calculations for the grade adjustment at intersections and access ramps to the main road. The firm defined a typical section that accommodated three lanes in each direction, pedestrian sidewalks, and a bicycle lane. The flexibility and accuracy of Bentley software saved significant time and enhanced efficiency.
Using PowerCivil for Brazil greatly simplified the design process with an interactive design environment that automatically accommodated changes in the layout. Bentley tools enabled Sotepa to perform geometry studies faster and more efficiently, allowing a 20-kilometer signaling project to be completed in two days. Compared to similar projects, the geometric design of the extension was completed in 25% less time. The Humberto de Campo extension is expected to help regulate Blumenau traffic, reduce bridge traffic jams, and facilitate growth of the city.
The flexibility and accuracy of Bentley software enhanced productivity, accommodating challenges of space and terrain to design an ecologically and environmentally sustainable roadway. PowerCivil for Brazil tools enabled Sotepa to perform complex calculations for the grade adjustments and allowed the horizontal layout to be changed interactively by adjusting vertices. The software automatically updated the vertical intersections eliminating the need to redesign the layout.
