‘Site Layout Planning Waste’ Typology and Its Handling Through AR-BIM Concept: A Lean Approach

Abstract

Site layout planning (SLP) aims at the efficient placement of temporary facilities on a construction site. Improper planning can lead to tremendous wastes in terms of unnecessary transport of materials and other resources around the site. A plethora of research has presented SLP as an optimization problem, but a few have focused on the wastes involved and that occur due to an improper layout of the construction site. To develop the 'SLP waste' typology, a comprehensive literature review was done, and the experts of SLP were interviewed. The identified wastes were found to be resulting due to inefficient layouts, improper coordination and collaboration among the project stakeholders and conflict of their interest. The interviewed experts highlighted the inefficiency of two-dimensional (2D) drawings and requirement of three-dimensional (3D) visualization that can aid in envisioning the future site scenarios. Therefore, utilizing Augmented Reality (AR) integrated Building Information Modeling (BIM), a conceptual tool 'AR-BIM' is proposed, and the anticipated working is briefed out in this study. The tool is under development and is expected to ease out the planning of site layouts and will aid in enabling lean, along with value generation in construction projects.

Waste Management Using Lean Construction and Building Information Modelling: Systematic Literature Review

“…On the other hand, the role of BIM in achieving Lean supply system is to support pull information from production conditions to the supplier, in order to deliver the right material, at the right time according to schedule, in the right place corresponding to SLP, which defines Just-in-Time in SCM. Lean-BIM integrations help to improve process transparency through SLP that assist stakeholders in understanding temporary facilities to provide better allocation on the site [39]. Lean and BIM facilitate strategic, tactical and operational analysis to support SCM decisions, through design for safety, material logistic, utilisation, resources distribution, pathing and routing address [40], [41].…”

Leveraging BIM and Mixed Reality to Actualize Lean Construction

“…This approach makes the decisionmaking process at the design phase reliable and efficient, because it avoids time delays due to re-works, thanks to an on-site acquisition of information about the designed model and the opportunity to do adjustments in an immersive hybrid environment (Orihuela et al, 2019). The second one is a process-oriented planning and control platform, which exploits BIM, advanced computation and visualization to enhance decision-making in work planning, workspace management, coordination and collaboration during work execution, in order to eliminate wastes due to delayed response to the unexpected, blocked space and passages (Singh & Delhi, 2018). Both tools have been enabled by the development of the design model within a Building Information Modelling (BIM) environment.…”

Mejora en la construcción por medio de lean construction y building information modeling: caso estudio

“…La edificación abate las necesidades de infraestructura, para actividades culturales, económicas, de desarrollo y sociales [2]. Pero en el sistema tradicional de la obra, las fallas de planeación se traducen en pérdidas económicas y de tiempo [3].…”
