PT. Wijaya Karya Implements Digital Strategy for Landslide Disaster Protection - 1

Advancing Infrastructure Project Summary Organization PT. Wijaya Karya Solution Environmental Engineering Location Cianjur, West Java, Indonesia Project Objectives • To provide a feasibility study for the reconstruction of a landslide-affected major thoroughfare in West Java. • To implement a 3D digital BIM strategy for design and construction management. • To optimize efficiencies to reduce project design schedule, on-site risks, and overall costs. Products Used Open Buildings Designer, ContextCapture, gINT, LumenRT, Navigator, OpenRoads, PLAXIS, ProjectWise, ProStructures PT. Wijaya Karya Implements Digital Strategy for Landslide Disaster Protection Bentley's BIM Methodology Provides Integrated Solution to Overcome Hazardous Topography Fast Facts • A catastrophic landslide devastated a 407-meter major roadway in West Java, Indonesia. • WIKA implemented a 3D digital BIM solution to restore and improve the roadway within a tight five-month schedule. • The team used Bentley's integrated applications to establish a connected data environment for data capture, design, and construction management. ROI WIKA performed data capture and modeled existing site conditions in one day with ContextCapture and aerial drones. Providing a digitally integrated modeling environment saved USD 660,000 in design costs. WIKA reduced design time by up to 30 percent using ProjectWise to streamline workflows and share information. Rebuilding After Catastrophic Landslide Indonesia's Homecoming Festival symbolizes the end of Ramadan, and since the country contains the largest Muslim population in the world, the event is significant. Three months before this annual celebration, a catastrophic landslide affected the road between Bogor and Cianjur, worsening the already terrible traffic situation on West Java's main thoroughfare. The Ministry of Public Works initiated a quick remediation response and retained PT. Wijaya Karya (WIKA) to resolve the devastating impact and prevent future landslide occurrences in the area. The USD 2.9 million project required WIKA to perform a feasibility study for effective landslide protection while initiating reconstruction and preventive measures on a 407-meter-long stretch of the roadway. The project site presented several hazardous geological and environmental conditions because it is surrounded by steep, sloping terrain and is affected by heavy rainfall. In addition, the road is heavily traveled and offers a limited work zone. Therefore, the government imposed a tight five-month schedule to minimize traffic disruption and accommodate the timing of the festival. Faced with potentially dangerous and complicated site conditions and a short timeline, WIKA needed to perform design and construction tasks simultaneously. Recognizing that a traditional design approach would fail to meet these challenges, WIKA implemented a digital strategy for data capture, design, and construction management, using Bentley's integrated BIM and reality modeling applications. Leveraging Reality Modeling WIKA properly investigated the project site using unmanned aerial vehicles coupled with ContextCapture to capture images, perform ground extraction from the reality mesh, and produce a digital terrain model that provided an accurate representation of the existing site. The reality modeling software facilitated a digital survey of the 12.8-hectare area with clear visualization to help with site security management and fieldwork optimization. This survey methodology alleviated the risks associated with manual data acquisition amid the hazardous landscape. Using the aerial drones and Bentley's reality modeling application enabled the team to complete the entire data capture and digital terrain model of the existing site within one day compared to one week using conventional methods. WIKA maximized the captured and modeled site information, eliminating the need for on-site surveys, ensuring personnel safety, and optimizing roadway design relative to the actual site. Integrating Bentley's interoperable BIM technology allowed WIKA to leverage data directly from the ContextCapture reality mesh to design a 3D model of the landslide protection elements within 10 days compared to one month using traditional modeling methods. The team identified the location of the nearby river and analyzed constructability in real-time to reconfigure the pier design and determine a solution that avoided disturbing the natural river channel. A Connected Data Environment WIKA established an open, connected data environment based on ProjectWise® that improved collaboration and streamlined workflows among stakeholders to reduce project design time by 30 percent. The integrated connected data environment accelerated information exchange to resolve typical data sharing and delivery issues among the multiple engineering disciplines and between the field and offices. The team used ProjectWise to coordinate and manage files shared among multidiscipline teams, simplifying file sharing and design modification between the office and field engineering. Navigator allowed field engineers to review the 3D model and receive real-time updates and material quantities information as a result of design changes. The integrated project delivery platform facilitated better project coordination and accelerated reliable information exchange from field personnel to identify and resolve potential costly issues on-site. Working in a connected data environment, with cloud-based support through Bentley CDE design capabilities helped manage deliverables, capture field data, and share files. The dispersed team effectively collaborated and supported work processes to seamlessly progress and keep the project on schedule.
