PT. Wijaya Karya Optimizes Design and Construction of Teluk Lamong Bridge - 1

CASE STUDY Bentley Advancing Infrastructure Project Summary Organization PT. Wijaya Karya Solution Bridges and Reality Modeling Location Gresik-Surabaya, East Java, Indonesia Project Objectives • Implement 3D BIM strategies to improve productivity for detailed engineering design and construction of Teluk Lamong flyover bridge. • Establish a connected data environment to enhance data quality and simplify collaboration among numerous departments. Products Used OpenBuildings Designer, ContextCapture, Descartes, LEAP, LumenRT, Navigator, OpenBridge Modeler, OpenRoads, ProjectWise, ProStructures PT. Wijaya Karya Optimizes Design and Construction of Teluk Lamong Bridge Implementing 3D Digital Workflows with Bentley Software Saves Significant Time and Costs Fast Facts • WIKA was awarded an IDR 1.3 trillion, BIM-mandated contract to design and construct the Teluk Lamong flyover bridge. • The team created a reality mesh from a site survey to ensure the design accommodated existing infrastructure. • WIKA used Bentley's civil design applications for parametric modeling, clash detection, and analysis to optimize design and construction. WIKA generated automated bills of quantity directly from the 3D models, saving IDR 3.9 billion in costs because of volume efficiencies. Performing clash detection to avoid rework saved two months in construction time and significant costs. WIKA saved 52 days in design time by using a 3D BIM solution compared to traditional 2D workflows. A New Approach to Indonesia Infrastructure Located in Surabaya, East Java, one of the busiest port cities in Indonesia, Teluk Lamong Terminal transports goods locally and regionally, creating heavy traffic congestion along the access roads. As part of the country's National Strategic Program, the Indonesian government initiated the IDR 1.3 trillion Teluk Lamong flyover bridge project to eliminate bottlenecks around the port and minimize traffic jams to and from the terminal. Connecting the terminal with the Gesik-Surabaya toll via the outer west ring road, the 2.4-kilometer-long roadway bridge is expected to reduce travel times from approximately one to two hours to 15 minutes. PT. Wijaya Karya (WIKA) was awarded the main contract from the Indonesian government that requires BIM implementation for detailed engineering design and construction. This infrastructure project was the first construction initiative using BIM strategies in Indonesia. WIKA faced additional challenges on the bridge project because there were site, time, and budget constraints. To avoid intervention with cemeteries, charitable land, and religious relics, as well as to accommodate two major highway crossing points and an existing railway, the bridge necessitated a unique design with elevated curved contours. WIKA needed user-friendly, integrated applications to effectively implement mandated 3D BIM workflows to accommodate dispersed stakeholders who work in 2D processes within the one-year project deadline. The company adopted Bentley modeling technology to improve existing processes, simplify integration among disciplines, and deliver quality throughout the project lifecycle. An Integrated Digital Solution "The idea is to implement BIM processes using Bentley's solution. We tried [implementing BIM processes] with other software, but we could not transfer the data from one application to another. The interoperability of Bentley software is key," explained Novias Nurendra, WIKA's system development department general manager. WIKA performed a survey, establishing ground control points for topographic data and using drones for aerial photogrammetry, to gain a better understanding of the existing site. The team used ContextCapture and LumenRT to generate a reality model from the captured survey data and imagery in one week, compared to one month using traditional methods. Working in an immersive reality environment facilitated design strategy, accommodating all existing infrastructure and environmental and cultural site restrictions. Combining Bentley's reality modeling and 3D civil design applications allowed WIKA to examine constructability in real time through construction simulation. The interoperability of Bentley software established new digital strategies in a connected 3D BIM platform, optimizing design scheme to reduce construction errors on-site. The integrated modeling solution minimized difficulties in early engineering stages, improving quality, reducing costs, and shortening design and construction time. Interoperable Design Applications Deliver Savings WIKA used Bentley's interoperable 3D civil modeling and analysis applications to implement 3D BIM processes and optimize the Teluk Lamong bridge design. OpenRoads" ensured road alignment was designed in accordance with standard codes, while OpenBridge" Modeler enabled parametric bridge modeling to evaluate the bridge geometry and interaction with the proposed road alignment. The ability to perform clash detection allowed WIKA to identify potential problems early in the design phase and avoid costly rework during on-site construction that would have adversely impacted the short project timeframe. "Using BIM [methodologies], we visualize[d] everything and [determined] that the position of the pier head was not proper because it was in the middle of the highway," Nurendra said. "Knowing this in advance [prevented an] improper design that would have cost two months of construction time." Integrating LEAP® facilitated accurate design and analysis of the unique, combined steel and concrete girder structures to ensure structural integrity and compliance with industry standards. The software provided the team with a steel
