Building Information Modelling (BIM) is recognized as an enabler for proficient accomplishment of projects in construction industry at different levels. Various benefits have been achieved globally through BIM implementations including enhanced visualization, collaboration between stakeholders throughout the project life cycle, time and cost savings, value engineering, change management and many others. Harnessing the BIM capabilities efficiently to gain maximum benefits on the projects can be a major milestone for the Indian built environment sector. For this study, BIM has been identified as an effective process for achieving various lean benefits for construction projects in India.The project envision BIM as a catalyst for improving the current scenario of Indian construction sector. The paper is based on exploration case based research methodology wherein, both literature review and semi-structured interview have been done. Relationship between BIM and lean by studying the use of various BIM capabilities on construction projects from initiation stage till operations and maintenance stage has been established. Lean benefits corresponding to each BIM capability has been reported upon validating in discussions with the industry experts and literature review.
The Last Planner® system (LPS) has witnessed a major shift in implementation at the onset of Coronavirus disease 19 . Governed by maintaining social distancing and many other safety restrictions, some construction practices including LPS implementation are now taking place in the virtual environment. However, potential challenges and enablers of implementing LPS in such an environment are yet to be investigated. This paper presents a framework based on lean philosophy and aims at successful implementation of LPS in a virtual environment. The framework calls for embracing a strong lean culture in the virtual work environment. The study also seeks to outline the challenges and enablers of this implementation. The framework was tested on a construction project through an expert panel. Results show that the framework is promising, and that although COVID-19 inflicted many challenges, it also had some positive impacts on LPS implementation. The framework will help practitioners and managers adopt a systematic approach from initiation to implementation of LPS in a virtual environment.
Lean construction is an approach that prioritizes enhancing quality and value while minimizing waste. Lean management comprises of principles and concepts that must be observed to effectively implement Lean management and leverage its benefits. In line with Lean concepts and principles, appropriate behavior and culture must be properly implemented to achieve successful Lean management, hence necessitating the use of an established health check assessment to evaluate the level of Lean maturity. This study aims to introduce a health check assessment to ascertain the level of maturity of Lean behavior and culture in the construction industry. The health check assessment was formulated by identifying Lean success factors, which were further validated by Lean experts. The methodology employed to achieve the study objectives follows a Design Science Research (DSR) approach, which involves creating a health check framework and evaluating it through an expert panel interview among project parties in a real case study project. In addition to the Lean expert panel interview, other performance metrics, such as percent planned complete (PPC) and constraint information, were collected. The proposed framework was validated, and the results indicate that there may be a correlation between effective team communication and project performance.
