BIM innovation for smart planning and construction
BIM awareness is incomplete unless all the three levels — geometry, information management, and process management — are present. All the three levels were dealt with at length in the session titled BIM: Developments and Innovations, moderated by Uwe Huttner, IB&T Software GmbH on the second day of INTERGEO 2021.
In information management, local knowledge is a core requirement for the construction, maintenance and repair of underground pipelines. Photos of open construction pits, existing local expert information or specific contact persons have been proven to be enormously valuable to make infrastructure projects run smoother and more economically.
“The value of underground infrastructure is underestimated,” said Lisa Wolff, Deputy Project Manager, localexpert24. A digging operation might go awry if accidental damage is caused to underground infrastructure. It could lead to construction trouble, increased costs, delays in project completion, and unhappy residents. It could result in power outage, hit water supply, gas supply, etc. To a large extent, situational accuracy on underground infrastructure is missing.
Plans cannot be as accurate as the real picture. Taking the example of underground cables, how they run underground, who laid them there, and how to get in touch with the right people requires location expertise and thorough documentation. Wolff said that localexpert24 has over 9,000 documentation points across Germany addressing situational accuracy on underground infrastructure.
Workflow and Geometry
Simon Bunya, Account Manager, EPLASS Project Collaboration talked about his company’s offering, the DESITE integrated, project collaboration platform workflow. The EPLASS Common Data Environment (CDE) allows for 360 degree views, and the ability to zoom in and out without the need for installing anything on the computer as it is Cloud based. Through the integration of DESITE in EPLASS, collision checks can now be run, and 4D and 5D simulations can be created. EPLASS has also developed new applications for the infrastructure sector such as an EPLASS defect management and a construction diary.
Wahid Fazelly, IB&T Software GmbH talked about BIM in railway design, focusing on track information and geometry. “It is important to extract information from the real situation,” Fazelly said, elucidating about IB&T’s CARD_1, an innovative all-in-one CAD solution in Civil Engineering for Planning, Surveying & BIM.
Use cases of smart planning
The session on use cases of smart planning and construction was moderated by Gunther Wölfle, which again talked about BIM life cycles in openBIM, its use in the reconstruction of Paris’ Notre-Dame Cathedral, utilization of BIM methods in Germany by civil contractors and surveyors.
Thomas Tschickardt, Digital Construction Manager, Wayss & Freytag Ingenieurbau AG discussed the life cycle approach with openBIM. The BIM method is currently still being tested in infrastructure sector, especially in the execution and maintenance phase. OpenBIM methodology throughout project A 10/A 24, which is the first highway project in Germany where implementation of BIM from design and execution to maintenance is pursued in a comprehensive and life cycle oriented approach. Speaking on the project, he mentioned that it was complex to integrate BIM into it as a distance of 30 km was already constructed, including about 20 bridges.
