PowerCivil for Brazil Shifts Sotepa’s Focus - 1

CASE STUDY Image courtesy of SOTEPA Ltda Project Summary Organization Sotepa Ltda Solution Roads Location Blumenau, Santa Catarina, Brazil Project Objectives • Design an extension to Humberto De Campos Street to connect between inner and outer ring roads to improve mobility within Blumenau. • Enhance public transportation through provision of dedicated bus lanes. • Define alignment within 30-meter right-of-way constrained by the narrow river valley, rugged topography, and unstable soils. Products Used MicroStation, PowerCivil for Brazil Fast Facts • Sotepa’s design accommodated three lanes in each direction, pedestrian sidewalks, and a bicycle lane. • Sotepa used PowerCivil for Brazil to efficiently design a single alignment with multiple independent grades, and grade adjustments for intersections and access ramps. • PowerCivil corridor modeling tools enabled designers to quickly and easily optimize the horizontal alignment and vertical intersections. PowerCivil for Brazil Shifts Sotepa’s Focus from Software to Solutions Sotepa Takes 25 Percent Less Time for Design of Six-lane Connector Road Using Bentley’s Powerful Civil Software A Blumenau 2050 Project The City of Blumenau, Santa Catarina, Brazil, retained Sotepa Ltda. as consulting engineer on the 2050 Blumenau Project for Urban Infrastructure. The firm was tasked with designing the Humberto de Campos Street Extension, a southwest radial connection between the city’s inner and outer ring roads intended to improve mobility in the narrow river valley. Sotepa defined a cross section that accommodated three lanes in each direction, pedestrian sidewalks, and a bicycle lane. PowerCivil for Brazil was used to design the 1.8 kilometer extension, which required a distinct grade for each lane as well as grade adjustments at intersections and access ramps. Compared to similar projects, the design took 25 percent less time to complete using PowerCivil for Brazil. Connecting Neighborhoods Situated in the Itajaí-Açu River Valley, where disastrous floods and landslides are commonplace, the City of Blumenau was challenged to improve mobility for its more than 300,000 citizens. The road infrastructure had been adapted to the geography, but the lack of space resulted in narrow roads with few connections between neighborhoods. The city’s transportation planners identified a potential solution as early as 1970, when a plan for inner and outer ring roads with radial streets was first idealized. In 1978, the city envisioned a new connector in ROI • Sotepa completed the design in 6.5 months, with design taking 25 percent less time than similar projects. • The BRL 25 million extension will pay for itself in 2.2 years in the form of savings to society. PowerCivil enabled Sotepa to meet the project’s fast-paced production schedule and deliver the required 3D models. a then-undeveloped section between Marechal Deodoro and General Osorio streets. Subsequently, the city began acquiring right-of-ways along the proposed route for the southwest radial known as Humberto de Campos Street Extension. In 2008, the 2050 Blumenau Project was introduced to establish planning and design guidelines for the city’s infrastructure. The goal was to promote public transportation, accommodate pedestrian and bicycle traffic, maintain ecological sustainability, integrate with the landscape, and not exacerbate extreme flood events. The Humberto de Campos Street Extension received BRL 25 million in funding with the aim to connect downtown Blumenau to the outskirts of the city via the previously envisioned route. Narrow Right-of-way As a pioneer of infrastructure solutions for Brazil since 1972 and a consulting engineer on the 2050 Blumenau Project, Sotepa was selected to execute this challenging project. The scope of work was to provide survey and mapping; geotechnical and geological investigations; environmental assessment and planning; road, bridge, and overpass design; and public hearing presentation. Three-dimensional models were required deliverables. Sotepa had 6.5 months to complete the design, but the contractor required 30-day progress reports. Significant challenges emerged almost immediately. The project required crossing a now densely populated residential district subject to a daily traffic volume of 50,000 vehicles. The geometric design was restricted by the city’s early vision and land acquisition. The total available width was just 30 meters; deviations from the original layout had significant cost impacts, given the limited budget for additional right-of-ways. The history of severe flooding made stormwater management and drainage another critically important factor. The valley was bisected by the Itajaí-Açu River and riddled with tributaries. Geotechnical investigations revealed poor soils, resulting in the need to borrow material for the site. Environmental protection also factored into the design, including mitigating impacts on vegetation and wildlife.
