Integrated Factory Modelling: Using Bim to Disrupt the Interface Between Manufacturing and Construction in Factory Planning

Abstract

The interface between construction and production is an area of research with rising importance given its increasing demand for efficiency gains in factory planning and construction planning processes. In fact, nowadays, it is usual for production and surrounding buildings to be planned separately as independent entities. According to the Laboratory for Machine Tools and Production Engineering of RWTH Aachen University, it is against this background that recent factory planning projects have reported cost increases and time delays due to non-transparent information between different planners. Building Information Modelling (BIM) addresses precisely this problem. However, BIM is barely used in projects for production planning of factories. This is critical since factory planning has to deal with more complex planning parameters (due to the technical building equipment) compared to private housing construction or public building construction, where BIM is already being applied increasingly. In order to close this gap, it is first of all important to create transparency within the individual information interfaces between production planning and building planning. This article addresses this issue and identifies major obstacles in interdisciplinary cooperation between building planners and production planners. For this purpose, an interdisciplinary and partially standardised study has been carried out using questionnaires and partly-open expert interviews. The results show scarce implementation in factory planning projects due to (1) missing maturity level specifications and (2) missing data management standards. Both theoretical and practical implications of this study as well as limitations and future directions for research are discussed.

How to Improve Collaboration Efficiency in the Built Environment of Factories by Using an Integrated Factory Modelling Concept – An Expert Study

“…In the following, the concrete solution recommendations as results of the expert study are presented, aiming to solve the obstacles investigated by Burggrä f et al [10].…”

“…The first concrete solution recommendation addresses the obstacles 1 and 3 from Burggrä f et al [10] (see section 1).…”

“…The concrete solution recommendation from our expert study addressing obstacle 2 from Burggrä f et al contains the development of documents and artefacts based on buildingSMART standards [10,15].…”

“…Factory design process [5,6,9] However, even in factory design projects where BIM is used, the two systems are still not planned in a coherent way. Burggrä f et al [10] have contributed this phenomenon to three major obstacles:…”

“…Ma et al described how collaboration in the construction industry can be improved through Integrated Project Delivery (IPD), especially in the design phase of buildings. Missing representation of the relationships of the deliverables with each other (third functional requirement of the model according to Ma et al) is one of the core problems in BIMbased factory design already described by Burggrä f et al [10], although Ma et al did not describe their explanations on a parameter level. Furthermore, the researchers focused on the HVAC area (Heating, Ventilation, Air-Conditioning), but without referencing industrial construction or the consideration of BIM [14].…”
