This paper presents a computational framework to study the effects of the use of analogy in design teams on team cohesion and team collaboration. The paper also reports on the new conceptual insights and lessons learnt while developing the model. The lessons learnt are particularly useful, because the use of computational models to study social aspects of team work in design research is still a fairly recent development, and the challenges and benefits in the process of formalizing abstract concepts into computational details are rarely discussed in the literature.
Monitoring the progress of a large construction site manually is a challenging task for managers. By collecting visual data of the site, many monitoring tasks can be automated using machine vision techniques. In this work, we study a new method of collecting site data, which is through crane camera images used to create 3D point clouds. The technology is cost-effective and enables automatic capturing and transmission of on-site data. To automatically extract buildings from the as-built point clouds, we present VBUILT, which uses 3D convex hull volumes to identify building clusters. Experimental results on 40 point clouds collected over four months on a large construction site show that the proposed algorithm can identify building clusters with 100% accuracy.
Flow is one of three perspectives in the Transformation-Flow-Value (TFV) conceptualization of project production systems. Accordingly, many papers published in the IGLC proceedings and elsewhere have addressed flow on a theoretical or practical basis. This notwithstanding, quite a few of these papers describe various flows only loosely without defining them formally. For example, a term such as workflow is widely used in the Lean Construction literature, but what exactly does it refer to? This paper poses the question: What kinds of flow can be distinguished? In response, different kinds of flow are listed, some already well-described and others (e.g., assembly flow) seemingly overlooked in the Lean Construction literature. The contribution of this paper is distinguishing and defining a certain number of flows in construction, using a vocabulary that is internally consistent. Flows need comprehensive attention in the design and execution of Lean Construction systems, so it is important to be clear on terminology. The goal of providing definitions regarding flows in Lean Construction is to facilitate research and communication of ideas with scholars and practitioners around the world.
