The early stages of building design involve the consideration of different design variants and their assessment regarding various performance criteria including energy consumption and costs. During the design process, the involved experts from different disciplines frequently exchange building information to develop a design that satisfies the project’s requirements and objectives. In the course of this iterative process, the building design evolves throughout multiple refinement stages. At the same time, different variants are developed. In BIM-based projects, the maturity of the design information provided by the model is expressed by the notion of Level of development (LOD). So far, however, there is no method to formally define the information requirements of a LOD. In particular, there are no means for expressing the uncertainty involved with the provided information. By contrast, despite the insufficient information available in early design stages, a BIM model appears precise and certain. This situation leads to false assumptions and model evaluations, for example, in the case of energy efficiency calculations or structural analysis. Hence, this paper presents an overview of a set of approaches that were developed to alleviate and preserve the consistency of the designed solutions. The approach includes the development of a multi-LOD meta-model, which allows one to explicitly describe the LOD requirements of each building component type incorporating the possible uncertainties, e.g. concerning the building dimensions. On the basis of this multi-LOD model, methods for evaluating a building design’s performance regarding the building’s structure and life cycle energy performance are proposed that take the defined uncertainties into account. To support the management of design variants in one consistent model, a graph-based approach is introduced. Finally, a minimized communication protocol is described to facilitate the workflow and communicate the evaluation results for supporting the decision-making process.

“…There is substantial research on design change management, which involve graph theory based model for the identification of possible domino effect of making changes preceding their implantation in design projects (Isaac and Navon, 2013;Mattern and König, 2018). Moayeri et al, 2017, developed a model to aid owners and their agents consider the impact of design changes by visualising the design-change and generating a detailed report for each envisioned design change and its ripple effects.…”

The management and the identification of design changes constitute an essential part of the of a design flow within the architecture, engineering and construction (AEC) industry, requiring the formalisation of a multi-disciplinary collaborative information modelling environment. Construction projects generate substantial amount of change information, which needs to be updated continuously throughout the process, from initial feasibility study to the decommissioning of facilities. Complications arise from the information storage in multiple incompatible file formats that can lead to the loss or omission of details. In addition to any unexpected changes, the mismanagement of information is another factor leading to delays and costly errors. In order to mitigate such issues, this paper proposes to integrate the Industry Foundation Classes (IFC) data model and Natural Language Processing (NLP) to validate and visually identify the result of change requests. The system is developed using C# by 1) integrating angular framework with ASP.NET (Active Server Pages) to create a dynamic single web page and 2). Using X-BIM toolkit that supports IFC format to read, create and visualise the BuildingSmart Data Models (aka IFC Models). This approach enables a web-based platform capable of generating reports and visual previews, highlighting the differences between IFC files throughout the design processes. A web-based system prototype allows users to compare subsequent versions of IFC design models in terms of additions, modifications and deletions. The prototype uses NLP to intelligently identify the changes that have been made as it compares newer and older versions of the same model, making this information available to designers and 3D modellers. Prospective work will focus on the application of artificial intelligence (AI) to automate the implementation of changes within the construction models.

“…As the planning process proceeds, more suitable and preferred variants are elaborated in more detail while other drafts are rejected or discarded. Mattern & König (2018) introduce a concept for the model-based management of design variants. The developed idea eliminates the need to use separate models for partially similar and yet different design variants and thus avoids redundant information.…”

The early conceptual architectural design phases are characterized by a constant interplay of creating variants and assessment of those variants as well as their consistent detailing. Variant comparison plays a significant role in achieving the desired final building. Objectifiable criteria used for the evaluation and comparison of design variants can be used to legitimize decisions and selections as the design process proceeds. Moreover, using these criteria, such as the results of simulations and analysis performed by various domain experts, most likely leads to building designs with better performance. One major challenge in practice today is the management of design information and collaboration between several actors in a building project. A large portion of the Architecture, Engineering, and Construction (AEC) industry still deals with conventional methods to exchange design information. The growing use of building information models is promising, but even the most recent developments and practices still rely heavily on human-readable protocols and issue management systems (Beetz 2009;Borrmann et al. 2018). Considering the potential of schematized computer-readable communications to be analyzed and used for future references and case-based reasoning systems, this paper proposes a novel minimized communication protocol based on BIM, which aims to introduce a computer-readable, yet adaptive universal method/function which works on schematized information exchange requirements (templates) for different use cases. Furthermore, this concept will be explained and demonstrated using an example scenario.
