However, the adoption of those systems requires an intense exchange of information to integrate the production of components, logistics operations, and site assembly. This is particularly important in engineer-to-order environments, in which the level of uncertainty tends to be high. This research proposes a model for planning and controlling the delivery and assembly of ETO prefabricated building systems, emphasizing the integration between site installation and logistics operations. This model was devised in an empirical study carried out in a company that delivers and assembles prefabricated concrete structures. The main theoretical contribution is a set of approaches to implement the “pull production” and “reduce variability” principles in this particular context, exploring synergies that exist betwee...

Although industrialized building systems can potentially simplify the production process, there is usually a high level of complexity in ETO production systems, such as uncertainty in client demands, short lead-time, overlapping between project stages, and resources that are shared among different projects. In this context, logistics management plays a key role in terms of achieving project goals related to cost, time and safety. This research work proposes the combined use of principles from the Lean Production Philosophy and Building Information Modeling (BIM), as a mechanism to cope with the complexity involved in those types of projects. Although these can be regarded as two separate approaches for improving the performance of production systems in the construction industry, there are evidences that there is much synergy between them. This paper reports the development of a logistics planning and control model for site assembly of ETO prefabricated building systems using BIM 4D modeling. The main theoretical contribution of this research work is the understanding of the synergies between Lean principles and BIM functionalities that are applicable to site logistics management, providing an example of how this body of knowledge can be expanded. This investigation also provides some practical contributions on how to carry out logistics planning and control at different hierarchical levels, with the support of BIM 4D modeling, aligning this process with the Last Planner System of production control. Design science research was the methodological approach adopted in this investigation, and the proposed model was developed and tested in empirical studies carried out in a steel fabricator company that designs, fabricates and assemblies steel structures.

The Language-Action Perspective (LAP) has been suggested as a suitable approach to understand the management of commitments in the LPS. This paper aims to assess the contribution of LAP to understand construction planning and control systems based on LPS. Two case studies were carried out in different construction companies, both highly experienced on the use of LPS. The results reveal the role of LAP for creating explicit representations of commitment flows that can be used to explain the sources of complexity and failures in planning systems, as well as for describing the profile of planning and control meetings.
