Webinar Overview: 
Join us to to learn how FINLEY used Bentley software on this innovative design-build project. This new Interchange is critical to South Florida's transportation network as the Palmetto SR 826-836 Expressway is a major route to Miami International Airport. The four segmental flyover bridges are being built over multiple roads that carry an average of 430,000 vehicles per day. The segmental bridge ramps will be precast, balanced cantilever and erected with a 460 ft. launching gantry. The bridge lengths vary from 1,100 ft. to 2,450 ft. in length and are 47 ft.-wide, with a maximum span length of 266 ft.

FINLEY utilized BENTLEY's BriM solutions extensively to develop and detail several of the design inovations on this project:

  • Bentley REBAR software was used for faster design drawing and shop drawing production
  • RM Bridge v8i was used for the 3D longitudinal design models and generation of the 3D tendon path wireframe models
  • Integration of the RM Bridge 3D models was used with microstation for checking checking of web intersection conflicts with the external tendons
  • These software solutions enabled tendon geometry for four segmental bridges to be evaluated within weeks and segmental dimensions for the project could be established early in the design stages saving valuable time on the design-build project

Other innovative design solutions were the incorporation of Diabolos to allow for variable tendon geometry and continuous external tendon ducts and facilitate for stressing of any single strand or multiple spans in the future. The erection method was also optimized by developing incorporating an larger, aesthetically pleasing pier cap that allowed for high capacity jacks and tie-donws to elimnate the need for any falsework.
