Join UN-GGIM, WFEO & WGIC at GeoBIM 2020, as we discuss on the value and relevance of integrated geospatial and BIM for resilient infrastructure.
What is Resilient Infrastructure?
In its most real sense, infrastructure encompasses the built infrastructure (transport, industrial, and building) and the integrated built and natural systems that provide for the essential needs of society. In the context of infrastructure systems, resilience is an infrastructure asset’s ability to absorb the disturbances caused by disaster and climate risks (Arup, 2014) and retain its functionality and structural capacity. The widely accepted UN definition for resilience is ‘the ability of a system, community or society exposed to hazards to resist, absorb, accommodate to and recover from the effects of a hazard in a timely and efficient manner, including the preservation and restoration of its essential basic structures and functions,” (UNISDR, 2009). The high occurrences of disasters, associated climate change risks, and urban cities’ exposure to disasters have necessitated governments and communities worldwide to emphasize resilient and sustainable infrastructure.
The two key factors influencing resilient infrastructure are population explosion and climate-change risks and adaptation. So, we need a resilient and sustainable infrastructure to meet future generations’ requirements and re-build the aging infrastructure exposed to global threats and natural catastrophes.
Geospatial and BIM Solutions for Resilient Infrastructure
Technology is central to manage the complex interactions within building resilient infrastructures in sustainable cities. To achieve the goal of resilience, many of the low-and middle-income countries need to improve their construction processes by using integrated geospatial and engineering solutions across the construction lifecycle. The blend of a GIS layer with the BIM model provides designers with accurate information to design and construct resilient infrastructure, orientation, and even construction materials.
Application of Geospatial and BIM for Resilient Infrastructure
Insights Through Case Studies
May of the WGIC member companies are leaders in geospatial and engineering solutions. Our members play an instrumental role in providing geospatial and BIM solutions to address the critical infrastructure challenges of climate- change-related risks, energy risks (wasted fuel and carbon emissions), etc. The joint white paper by UN-GGIM, WFEO, and WGIC highlights the success stories on geospatial and BIM applications for resilient infrastructure.
Gorkha, Nepal – Earthquake 5th May 2015
Improved structural workflows, refined construction models, obtained insights into how buildings will perform (resilience), developed better quality designs and improved project quality/delivery to make projects more resilient and profitable.
Lisbon, Portugal - Operational Resilient Digital Twin Model
The use of digital twins enhanced the drainage capacity of existing stormwater systems – resulting in the creation of a new mitigation strategy – leading Lisbon to avoid 20 floods over 100 years and save 100 million of Euros.
United States - City Resilience from natural disasters with GIS
The long-term benefit of using ArcGIS is that it streamlines data collection processes and enable collaboration, communication and analysis of disaster impacted infrastructure on the basis of the needs and requirements of the users.
Faroe Islands, Denmark - Machine Control to lower climate change risks
The use of Leica Geosystems GNSS embedded excavators results in minimization of environmental footprint, fuel consumption, and consequently lowers carbon emissions, leading to a step towards building resilient infrastructure in the Faroese Islands.
Portugal - Alto Ceira project
The use of scanning technology is suitable in assessing dam structure, as well as of the near slopes in a fast, accurate and economical way. The data so collected is integrated with CAD software which helps in building resilient infrastructure.
Global - 100 Resilient cities
Data collected from satellite and UAV’s is accelerated and automated via the eCognition Essential Software for easy change detection transforming geodata into intelligence for building resilient infrastructure.
Chicago, United States - Metropolitan water reclamation project
The use of scanning technology provides a high degree of accurate data for monitoring and operations and maintenance of critical infrastructure projects with in the cities that are prone to the impacts of flooding.
Wyoming, United States - Mapping landslide-prone areas
Wyoming Department of Transportation (WYDOT) contracted Woolpert to utilize the organizations’ Terrain Mapper LiDAR sensor to deliver classified LiDAR data and aerial imagery to create highly accurate and custom digital terrain models to mitigate landslide areas.
