Synergies Between Lean Construction and Artificial Intelligence: AI Driven Continuous Improvement Process

30th Annual Conference of the International Group for Lean Construction, 2022 (engl.)​

Both, Lean Construction (LC) techniques and Artificial Intelligence (AI) methods strive for the continuous improvement of production systems in projects and organizations. A combined implementation of both approaches is an ongoing research area. Therefore, the question arises as to whether the added value generated by implementing both approaches jointly is greater than the added value generated by implementing them independently and what is the significance of people in their combined use. This paper explores theoretically the potential of synergies between LC and AI in the AEC sector with exemplary use cases as well as their resulting effects.

An Empirical Evaluation of Predicted Outcomes as Explanations in Human-AI Decision-Making

Proceedings of the European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases, 2022 (engl.)

In this work, we empirically examine human-AI decisionmaking in the presence of explanations based on predicted outcomes. This type of explanation provides a human decision-maker with expected consequences for each decision alternative at inference time—where the predicted outcomes are typically measured in a problem-specific unit (eg, profit in US dollars). We conducted a pilot study in the context of peer-to-peer lending to assess the effects of providing predicted outcomes as explanations to lay study participants.

Designing a Human-in-the-Loop System for Object Detection in Floor Plans

Proceedings of the AAAI Conference on Artificial Intelligence, 2022 (engl.)

In recent years, companies in the Architecture, Engineering, and Construction (AEC) industry have started exploring how artificial intelligence (AI) can reduce time-consuming and repetitive tasks. One use case that can benefit from the adoption of AI is the determination of quantities in floor plans. This information is required for several planning and construction steps. Currently, the task requires companies to invest a significant amount of manual effort. Either digital floor plans are not available for existing buildings, or the formats cannot be processed due to lack of standardization. In this paper, we therefore propose a human-in-the-loop approach for the detection and classification of symbols in floor plans.

Human-AI Complementarity in Hybrid Intelligence Systems: A Structured Literature Review

28th Pacific Asia Conference on Information Systems , PACIS 2021 (engl.)

Hybride Intelligenz ist ein neues Konzept, das die Komplementarität von menschlicher Intelligenz und künstlicher Intelligenz (KI) betont. Eine wichtige Voraussetzung für die Zusammenarbeit zwischen Mensch und KI ist die Interpretierbarkeit der von der KI getroffenen Entscheidungen. Im Rahmen einer strukturierten Literaturrecherche identifizieren wir relevante Faktoren, die die Zusammenarbeit zwischen Mensch und KI beeinflussen.


Artificial Intelligence for the Construction Industry - a Statistical Descriptive Analysis of Drivers and Barriers

1st International Conference on Disruptive Technologies Tech Ethics and Artificial Intelligence , 2021 (engl.)

In the construction industry, applications of artificial intelligence (AI) are still uncommon. Digitalization, industry 4.0 and the increasing implementation of AI systems already show a rise in efficiency and innovation in many industries. Thus, there are still untapped opportunities for construction.

The aim of this work is to identify drivers and barriers for the implementation of AI in the construction sector and its adjacent industries. Data on pre-vailing factors was collected in a systematic review of more than 100 studies, surveys, and statistics…

BIM Basics: BIM und KI in Wissenschaft & Unternehmenspraxis

buildingSMART Deutschland, 2021 (de.)

Die Rahmenbedingungen verändern sich im Zeichen des Wandels und der stetig notwendigen Erneuerung für Mensch, Gesellschaft und Unternehmen gleichermaßen rasant. Die Digitalisierung berührt alle Lebensbereiche und ist zugleich Verheißung, Fluch und letztendlich unumkehrbar.

Auch wenn vieles heute ungeklärt erscheint und sich im Stadium der Erforschung der Zusammenhänge befindet, so verbindet diese Publikation die Stichwörter BIM und KI, digitale Geschäftsmodelle, IoT und E-Commerce und zeigt Beispiele aus der Unternehmenspraxis auf.

Building the future of the construction industry through artificial intelligence and platform thinking

Digitale Welt, 24.01.2020 (engl.)

Data in the construction industry is heterogeneous, organizations do not work closely together, and construction software is highly specialized for individual users and applications. As a result, knowledge from previous construction projects is often not shared, linked, or transferred to subsequent projects. Additionally, the manual work on-site leads to long and unstable design and construction processes. Based on a review of common challenges in this work a new vision for the Architecture, Engineering, and Construction (AEC) Industry is developed...

The General Contractor Response to Platform Ecosystems​

IGLC, 27.07.2019 (engl.)

Platforms enable value-creating interactions between producers and customers by mediating between their users. Supported by digitization, platforms use large datasets and integrated production systems to enhance the customer and producer experience. The platform's business model is expanding in the economy as digitization increases...
