Building Information Deduced - State and potentials for Information query in Building Information Modelling

Abstract

In recent years, Building Information Models have become commonplace in building profession. The extensive use and increasing experience with BIM models offers new perspectives and potentials for design and planning. A recent stakeholder study conducted by the authors of this paper show that in practice models are no longer solely observed as culmination of knowledge in a 3d representation of future built structures, but as a source of information in itself. Experienced users of BIM want to Find Information within a model or across a set of these and Compare models in order to evaluate states of a model, differences in separate models or models from different point of time. Current BIM tools support both modes only in a rudimentary form. This paper discusses current modes of information query within and across BIM models, shows beneficial scenarios for building and planning practice through customised queries and exemplifies these on the base of a scripted tool. This customized approach is used to test approaches for a machine-based assessment of Level of detail and BIM-readiness in BIM models.

Investigation of Classification and Anomalies Based on Machine Learning Methods Applied to Large Scale Building Information Modeling

“…[1]. Using the BIM platform, the architectural design team, construction unit, operations department and other parties can exchange engineering information in real time and work together, improving work efficiency, saving resources, reducing costs and ultimately achieving sustainable development [2][3][4]. Since the advent of the Industry Foundation Classes (IFC), more integrated methods to share construction data have emerged and have thus become adopted industry-wide [5].…”

A CAD-Blockchain Integration Strategy for Distributed Validated Digital Design - Connecting the Blockchain

“…We present the first connection of a CAD system with a Blockchain on two levels of integration, along with the strategic description of two other possible levels with current technology. Connecting CAD and BIM systems with a blockchain can have a profound effect on the design of cities but also on their operations [Lombardi et al 2018, Tamke et al 2014. Previous efforts in distributed, interconnected systems have gone so far as creating protocols for plat-form agnostic communication between 3d software over the internet [Hnidek, J 2011] without though connecting CAD and 3d modellers with other programmes and protocols.…”
