Finalists for Year in Infrastructure 2018 Awards: BRIDGES
Bentley Systems announced the finalists for Year in Infrastructure 2018 Awards in the category of Bridges for going digital advancements in infrastructure:
- GS E&C Corporation
Jungkun-Jinjeong Bypass (Sueo-chon Bridge)
Gwangyang, Jeolla-Namdo, South Korea
Project Playbook: AECOsim Building Designer, ContextCapture, MicroStation, Navigator, OpenBridge Modeler, ProjectWise, RM Bridge
The USD 27.5 million Sueo-chon bridge project is part of a new 7.8-kilometer bypass connecting Jungkun and Jinjeong in Gwangyang, South Korea. A prestressed concrete box girder bridge, the main bridge spans 745.8 meters over a tidal river. GS E&C Corporation was retained as the main contractor to provide design review and construction services. Faced with revising the original bridge design and obtaining approval from the client and stakeholders amid a tight construction schedule, the project team implemented a 3D BIM and structural analysis solution and piloted its integrated engineering platform concept using Bentley technology.
GS E&C Corporation reviewed and analyzed the original design using RM Bridge, OpenBridge Modeler, and MicroStation, visually demonstrating its flawed structural integrity to the owner. Despite the short schedule, the project team performed an efficient review of design alternatives and provided a timely, economical redesign. Bentley applications saved USD 2.3 million in costs and resolved 245 potential clashes, shortening the construction schedule by 14.5 days. Working in ProjectWise’s real-time, collaborative modeling environment streamlined workflows and reduced errors. Navigator and MicroStation enhanced communication and understanding through 3D modeling and visualization of the new bridge design proposal.
- Indian Railways
Reality modeling facilitates efficient planning, construction and monitoring of Chenab Bridge
Reasi District, Jammu & Kashmir, India
Project Playbook: ContextCapture, OpenRail Designer, OpenRoads, OpenBridge, RM Bridge, STAAD
As part of a new railway project initiated by the Indian Railways, the Chenab Bridge will improve connectivity in the state of Jammu and Kashmir. The USD 184 million bridge will be the world’s highest rail arch bridge, at 359 meters above the riverbed with an arch span of 467 meters. Located amid rugged and mountainous terrain in a highly active seismic zone, the project presented numerous geological and alignment challenges affecting design and constructability.
Indian Railways used OpenRail Designer to accommodate the transition from a straight to curved bridge rail alignment. RM Bridge and STAAD helped with the structural behavior and analysis during the planning stages, while ContextCapture helped with construction planning, monitoring, and interim surveys and inspections. Using unmanned aerial vehicles to survey the site and generate a reality mesh with ContextCapture identified potential issues, managed site progress, and conducted construction inspections safely and efficiently. Using drones and reality modeling saved 225 resource days compared to traditional survey methods, resulting in a USD 40,000 cost savings. These strategies also reduced construction inspection time by 80 percent to save more than USD 100,000.
- PT. WIJAYA KARYA (Persero) Tbk
Design and Build of Road Bridge at Teluk Lamong Port Project
Gresik-Surabaya, East Java, Indonesia
Project Playbook: AECOsim Building Designer, ContextCapture, Descartes, LEAP, LumenRT, Navigator, OpenBridge Modeler, OpenRoads, ProjectWise, ProStructures
The IDR 1.3 trillion Teluk Lamong flyover bridge project is part of the National Strategic Program mandated by the Indonesian government to reduce severe traffic congestion along the road to and from Lamong Bay Terminal in Surabaya, East Java. The 2.4-kilometer-long bridge connects the terminal with the Gresik-Surabaya toll via the Outer West Wing. A unique bridge design with elevated, curved contours was required to accommodate three major crossing points and avoid religious relics and ancestral tombs. PT. WIJAYA KARYA (WIKA) was the main contractor, providing detailed engineering design and construction. To overcome the site constraints and meet a one-year project deadline, WIKA implemented a collaborative BIM strategy to deliver a piece of infrastructure that will further enhance economic growth in Surabaya and East Java.
The project team used OpenBridge Modeler and AECOsim Building Designer to build intelligent 3D models and automate bills of quantity, reducing overall design time by 80 percent. WIKA created an immersive reality mesh to optimize design strategy and accelerate construction using ContextCapture and LumenRT. ProjectWise and Navigator Mobile improved project coordination and accelerated information sharing. The team optimized collaboration and facilitated clash detection to save approximately IDR 5 billion in project costs by working in a connected data environment with Bentley’s integrated BIM technology.
