Project 

A USD 35 million highway and railway intersection redevelopment project in Aventura, Miami-Dade County, Florida consists of removing an at-grade railroad crossing and constructing a new 355-foot-long pedestrian bridge, widening an existing bridge, and constructing two new ramp bridges of 592 feet and 600 feet. AECOM was tasked with the initial planning phase to evaluate various concepts to determine a preferred design and was ultimately responsible for providing a final engineering design. The project team was faced with proposing a highway design that would reroute foot traffic and road access within tight property limits. AECOM also needed to minimize the environmental impact on nearby water drains and wetlands caused by idling vehicles waiting for trains to cross. 

Solution

AECOM implemented civil infrastructure information modeling (CIIM), which helped the project team visualize potential designs and measure the performance of features including sight lines and vehicular clearances. Once the team selected the final design, it streamlined the creation of cross-sections and simplified areas with complex grading. The team was then able to quickly evaluate the proposed structure, drainage, and road footprints, as well as adjust dimensions and details to avoid environmental damage. To collaborate effectively across the multidiscipline and distributed project team, AECOM established an open, connected data environment to allow each team member to access the latest data.
