The Westgate Footbridge in Auckland, New Zealand, links the community facilities of a shopping center, local library, and sports complex, which had been cut off from each other by highway expansion. The challenge of this NZD 5 million project was to design the approach ramp as a double spiral – with both left-handed and right-handed spirals – while minimizing its environmental impact on the local creek that it followed.

Used Bentley's ProSteel to create the bridge model, which served as the base from which it modeled, detailed, and fabricated a series of jigs that were then used to form the spirals and ensure the ends of the truss sections were accurate. The ProSteel model became the primary source of accurate information and allowed D&H Steel Construction to coordinate the precast concrete, foundations, handrails, throw screens, and pedestrian lighting.

Using ProSteel to deliver accurate shop drawings and a jig translated into significantly reduced man-hours. Being able to view and measure the fabricated elements from any orientation meant that the design team could accurately model the bridge profiles and cross sections, create pipe-rolling information, specify all truss diagonals, and more, all of which minimized the risk of errors. Delivery time was reduced through improved accuracy, reduction in man-hours, and timely availability of information to other disciplines. 

Software :Using ProSteel for 3D design not only halved the time necessary to detail the structure as compared to traditional 2D design, but also guaranteed that there was no lost time during the erection phase because the precast units fit perfectly. Reports produced via ProSteel were the basis of the team’s quality assurance procedures and provided the client with necessary quality assurance documents for welding and surface coatings.

Bentley Systems announced the immediate availability of LEAP Bridge Steel for the 3D modeling, design, analysis, and load rating of everyday steel bridges. The software, which adheres to AASHTO Load and Resistance Factor Design (LRFD) Specifications, enables users to leverage the benefits of bridge information modeling (BrIM), including increased efficiency and data reuse across the bridge lifecycle. It also provides the advantages of optioneering – which enables engineers to quickly consider trade-offs between multiple design strategies. When used with Bentley’s LEAP Bridge Enterprise software for concrete bridges, LEAP Bridge Steel provides bridge engineers and designers a comprehensive solution to evaluate multiple concrete or steel design alternatives.

Raoul Karp, Bentley Systems vice president, said, “The cornerstone of BrIM is intelligent information mobility, which fosters the use of data beyond bridge design and engineering to inform downstream processes such as fabrication, construction, operations, maintenance, and inspection. With easy access to information about the bridge, organizations can optimize business processes – across the bridge lifecycle.” He continued, “being a fully integrated product for superstructure and substructure analysis, design, and load rating, Bentley’s LEAP Bridge Steel uniquely facilitates information mobility across various project stages. In addition, the bridge designs can be used in conjunction with MicroStationGEOPAKInRoadsMXROAD, the Power Civil products, and InspectTech, which makes it easy for information to move between project disciplines. 

With LEAP Bridge Steel, users can:

  • create 3D models of bridge superstructures and substructures, including ground data, all in a single program;
  • quickly evaluate multiple alternative designs;
  • design and construct bridges of a higher quality; and
  • take advantage of the software’s intra-operability with other Bentley applications, including MicroStation, GEOPAK, InRoads, MXROAD, thePower Civil products, and InspectTech.

LEAP Bridge Steel users also benefit from faster and more reliable workflows as well as from rework being minimized – due to the accuracy and consistency of the 3D models.
