Conceptual Foundations for a New Lean Bim-Based Production System in Construction

Abstract

This paper presents a new lean BIM-based production system to face productivity deficiencies in construction. To prove whether the current situation can be improved, the aforesaid production system is designed to assess the hypothesis that a true integration of BIM functionalities with the Last Planner System will contribute to a more efficient project delivery. Although beneficial synergies of BIM and Lean have been widely described and acknowledged in research, previous work has not fully addressed the stated hypothesis, since it has only provided frameworks on how to use BIM and the Last Planner System in parallel. The core of the here-proposed lean BIM-based production system is the linkage of BIM objects at data processing level with the Last Planner System routines making use of digital Kanban boards. The production system will also be extended by cost control aspects of the Earned Value Management approach and thus represents the basis for a complete construction management system with respect to quality, schedule and costs. This paper discusses the first concepts of the new lean BIM-based production system and introduces an information system integration model as a starting point for future software development activities.

The Last Planner® System and Building Information Modeling in Construction Execution: From an Integrative Review to a Conceptual Model for Integration

“…It aims at both increasing schedule reliability and smoothening flow of work [36], and is been considered as one of the most import lean methods in construction execution [10]. The LPS strives for the achievement of its purposes through collaboration, transparency, continuous improvement as well as reliable commitments from the responsible persons for actual work completion, the Last Planners [37].…”

“…This procedure is shown in Figure 2. continuous improvement as well as reliable commitments from the responsible persons for actual work completion, the Last Planners [37]. According to Ballard [36], every possibly occurring task, needed for the completion of a construction project, can be technically categorized into four groups during its execution phase: (1) SHOULD-tasks include in principal all tasks needed for achieving global milestones defined by an existing master schedule or client's requirements.…”

Precast Concrete Building Construction Process Comparison

“…BeaM! is proposed as an integrated production system of both BIM and lean philosophy, which uses the digital Kanban board to communicate the BIM processing data with the last planner system (Schimanski 2019). Dallasega has introduced a decentralized and pull-based control loop in the construction engineering-to-order supply chain, which has been tested to benefit the project with labor-saving, on-time delivery, and early identified problems (Dallasega et al 2016).…”

Impact of BIM/LEAN on the interaction of construction project design teams

“…BIM in fact will become increasingly essential and an inextricably linked component to a Lean construction process, especially within the context of abundant geometric and semantic project information(Schimanski, Monizza, Marcher, & Matt, 2019). For example,Schimanski et al (2019) describe three practical case studies through BIM-based objectives and outcomes and map these outcomes to the taxonomy of interactions described bySacks et al (2010). All three case studies have demonstrated advances in the core tenet of delivering increased value to clients while significantly reducing waste in the form of time, material, and financing.…”

“…; "BeaM! ", which allows a joint application of BIM and the Last Planner® System (LPS)(Schimanski et al, 2019); and "KanBIM", which mixes Kanban and BIM(Sacks, Barak, Belaciano, & Gurevich, 2011). A Lean tool can be defined as an structured technique or instrument that facilitates the implementation of the Lean principles(O'Connor & Swain, 2013) , such as, the last planner system, 5S, big rooms, and…”
