Abstract
Purpose
Lean construction (LC) is an innovative approach in the construction industry that has shown significant success in developed countries. Although LC has potential in the construction sector of Pakistan, it has not been extensively explored. This study aims to address this knowledge gap by identifying and predicting current lean practices and assessing the strengths and weaknesses of LC implementation in Pakistan.
Design/methodology/approach
Using robust statistical methods to analyze 92 valid responses, the study reveals that approximately 54% of lean practices are currently in use in the construction industry of Pakistan, with a population mean ranging from 52.7% to 55.6%.
Findings
Surprisingly, the research identifies instances where some construction firms in Pakistan are implementing LC practices, even though they have only a limited understanding of its underlying principles. Notably, certain subprinciples, such as visual management, top management commitment to change, employee training, process cycle time reduction and production optimization, are less integrated within the construction industry. Exploring the possibility of implementing LC, recommendations for strategies to implement LC in Pakistan are suggested, aligning with the conceptual model proposed by the researchers.
Originality/value
The novelty of this work offers insights that can serve as a comprehensive guide for developing nations. It provides a structured approach to assess and benchmark LC practices, which, in turn, can contribute to a more efficient and effective construction industry. Moreover, the strategies proposed in this research can aid developing countries in the efficient implementation of LC. This will have a positive implication for both economic and developmental outcomes.

This study aims to set out to identify and evaluate potential obstacles to successfully implementing lean construction (LC) as a result.
Abstract
Purpose
This study aims to set out to identify and evaluate potential obstacles to successfully implementing lean construction (LC) as a result.
Design/methodology/approach
Several indicators were recognized as major obstacles following an exhaustive assessment of the literature and a multicriteria decision analysis based on the analytic hierarchy process (AHP) of information obtained from a questionnaire survey that was directed to practitioners in the Indian construction industry.
Findings
The results of this AHP model suggest that “Managerial” and “Inadequate resources” categories with a priority weight of “0.361” and “0.309” have the highest levels of influence, respectively, while “Inadequate knowledge” and “just in time (JIT)” categories with a priority weight of “0.053” and “0.034” have the lowest levels of influence, respectively.
Research limitations/implications
Construction companies can use the study’s findings as a guide to determine whether they are ready to embrace LC, learn more about the components needed for implementation or investigate any challenges that may arise. These businesses can then create plans to promote the adoption and application of the lean philosophy.
Originality/value
The Indian construction industry may see great success with LC management initiatives. LC concepts have been adopted by many nations, but during the past 20 years, there has only appeared to be a limited amount of lean implementation in the Indian construction industry. It seems that several structural and cultural barriers are preventing its effective implementation. Organizations will not be able to determine what improvement efforts are required, where these efforts should be directed or which initiatives could provide the best outcomes if they are unaware of the elements that influence the effective implementation of LC.

Abstract
Purpose
The purpose of this study is to ascertain the extent to which the practices of small and medium building contractors (SMBCs) conform to lean construction (LC) principles. Ultimately, practical results encourage a discourse on the true potentials and challenges to the holistic uptake of LC principles in the Ghanaian construction industry.
Design/methodology/approach
This research is based on a qualitative case study approach. The data was obtained through face-to-face structured interviews.
Findings
Across the cases, it was realized that there is a low-level application of LC principles among SMBCs. There was no indication that lean concepts were used on a company-wide basis in the Ghanaian construction industry. Furthermore, the study revealed that the traditional wasteful approach to managing construction projects was still prevalent among the firms.
Practical implications
This paper uses the 4P model as a foundation for assessing the extent to which the practices of SMBCs conform to LC principles. Practically, the study also created a certain level of awareness among the SMBCs about LC, LC principles and the benefits of the application of these principles within organizations.
Originality/value
This study contributes to the body of knowledge as it uncovers the status of LC implementation among SMBCs in the Ghanaian construction industry. The findings that are presented in this paper can be used as a starting point to disseminate the research and practice of LC among SMBCs.

Abstract
Purpose
This research aims to identify and measure the correlations between building information modelling (BIM) and lean construction (LC) principles at the design and construction phases.
Design/methodology/approach
The study investigates BIM-LC principles correlations using the Istanbul Grant Airport (IGA) as a case study. The Delphi technique, performed quantitatively, contributes to the identification and quantification of a set of correlations between 11 selected BIM uses and 13 LC principles, which are supported with practical examples from the case study.
Findings
Together, the two research methods provide an evidence-based approach to understand the correlations between BIM and LC. The correlation analysis results in 46 correlations, and the correlations between the LC principles and BIM uses are intensified with the LC principles.
Practical implications
A quantitative understanding BIM use and LC principles correlations and appreciation of their specific uses can guide the practical implementation of BIM and LC, especially in large and mega projects.
Originality/value
BIM and LC practices represent approaches to improve performance in construction projects. While BIM has both information technology (IT) and process perspectives, the LC approach is mainly a process and product-oriented philosophy for project efficiency, effectiveness and the elimination of non-value-adding activities and waste. Many studies have investigated how the two approaches complement each other and concluded that their combined implementation in projects can improve efficiency and effectiveness. However, to date an analytical and granular investigation identifying and measuring correlations between BIM and LC based on empirical data is lacking. This paper fills that gap with an evidence-based analysis of the tightness of coupling and correlations between BIM uses and LC principles.

Abstract
Purpose
The purpose is two-fold: (1) to explore the interactions of robotic systems and lean construction in the context of offsite construction (OC) that were addressed in the literature published between 2008 and 2019 and (2) to identify the gaps in such interactions while discussing how addressing those gaps can benefit not only OC but the architecture, engineering and construction (AEC) industry as a whole.
Design/methodology/approach
First, a systematic literature review (SLR) identified journal papers addressing the interactions of automation and lean in OC. Then, the researchers focused the analysis on the under-researched subtopic of robotic systems. The focused analysis includes discussing the interactions identified in the SLR through a matrix of interactions and utilizing literature beyond the previously identified articles for future research directions on robotic systems and lean construction in OC.
Findings
The study found 35 journal papers that addressed automation and lean in the context of OC. Most of the identified literature focused on interactions of BIM and lean construction, while only nine focused on the interactions of robotic systems and lean construction. Identified literature related to robotic systems mainly addressed robots and automated equipment. Additional interactions were identified in the realm of wearable devices, unmanned aerial vehicles/automated guided vehicles and digital fabrication/computer numerical control (CNC) machines.
Originality/value
This is one of the first studies dedicated to exploring the interactions of robotic systems and lean construction in OC. Also, it proposes a categorization for construction automation and a matrix of interactions between construction automation and lean construction.

Abstract
Purpose
The importance of lean and sustainability integration in sustainable construction (SC) has been extensively studied. However, a practical and thorough implementation methodology addressing the project life cycle phases is still inadequate. The present study has developed a novel phase-wise sustainable–lean implementation methodology for high-rise residential projects.
Design/methodology/approach
The current study has identified the 50 direct conceptual interactions between 11 lean principles and 11 sustainability criteria encompassing 44 different attributes covering 174 sustainability actions. A panel of nine experts validated these interactions, and 50 integration vectors were proposed addressing different phases of the project life cycle of high-rise residential buildings. The experts also analysed the identified integration vectors for their current and likely future implementation in high-rise residential projects.
Findings
The interactions between lean and sustainability principles led to the development of a phase-wise implementation methodology. The experts' survey responses on the current level of implementation revealed that 40, 32 and 28% of integration vectors were implemented rarely, sometimes, and frequently, respectively. For likely future implementation, 28 and 72% integration vectors were reported as very likely and extremely likely to implement, respectively. This survey response highlighted the usefulness of identified integration vectors for enhancing the sustainability of high-rise residential projects.
Originality/value
The proposed sustainable–lean implementation methodology acts as a comprehensive guideline for implementing a lean approach to achieve the objectives of SC in high-rise residential projects. This may facilitate the transition from conventional to sustainable building practices using a lean approach.

Abstract
Purpose
The construction industry sector is developing rapidly, especially with the increasing pace of the Fourth Industrial Revolution in this sector. Construction projects can benefit from greater integration and collaboration between their technologies and processes to reap the advantages and keep pace with the recent significant technological and managerial techniques developments. Therefore, this study aims to delve into and investigate building information modeling (BIM) and Lean Construction (L.C.) with a concentration on the potential BIM–lean interactions synergy and integration in the Jordanian construction industry.
Design/methodology/approach
This study takes exploratory nature, followed by the deductive research approach, and is designed to be a mono-quantitative research methodology. Moreover, the sampling technique is non-probability convenience sampling, and the research strategy is implemented through a questionnaire used and analyzed by using Statistical Package for Social Science to conduct descriptive and inferential statistical analysis and verify the reliability and validity through proper tests.
Findings
The BIM–lean interactions synergy and integration findings revealed that eliminating waste (time, cost, resources), promoting continuous improvement (Kaizen) and standardizing as lean construction principles are the most significant and agreeable toward achieving BIM–lean interactions synergy. On the other hand, “High 3D Visualization Modelling” was the most significant BIM function, followed by “Rapid and Auto-Generation of Documents and Multiple Design Alternatives” and “Maintenance of Information and Design Model Integrity.” Moreover, based on the relative importance index (RII) values, “Lack of Technical Expertise in BIM-LEAN” is the most significant challenge with a 0.89 value of RII, followed by “Lack of Government Direction and Standard Guidelines” with a 0.88 value of RII and “Financial considerations” with a 0.83 value of RII.
Originality/value
This study will help provide a new detailed overview that investigates the effects and expected benefits of integrating BIM processes and technological functionalities with lean construction principles within a synergetic environment. Moreover, the study will increase the awareness of using new technologies and management approaches in the architectural, engineering and construction industry, seeking to achieve integration between these technologies to reach ideal results in terms of the outputs of construction operations.

Abstract
Purpose
This paper aims to increase the integrity of the planning process with the executive process by simulating the Last Planner System (LPS) technique using building information modeling.
Design/methodology/approach
A five-dimensional model was prepared, and after specifying the number of physical conflicts on the plans, all the scenarios of the starting points in the expert contractors’ plans were analyzed. Accordingly, the best scenario was determined by LPS technique. To assess the performance of the study, it was implemented on several tasks of a construction project.
Findings
The results of this research indicate that if this method is used in the planning process, the time conflicts between the expert contractors who are in the critical path are reduced, and the total delay of the scheduled time reaches zero. In addition, the conflicts between contractors whose suspension will cause no incentive and increase the daily cost overruns will reduce to the lowest point.
Originality/value
By simulating LPS in the planning process, time-physical conflicts are considered at the lowest point. Using this approach, conflicts are detected before the execution process, resulting in a significant reduction in the delays and cost overruns in construction projects.

Abstract
Purpose
The purpose of this paper is to develop a solid understanding of how integrated building information modeling (BIM) is implemented in a mega project such as the (Istanbul Grand Airport IGA) construction project, which is the main case study in the research methodology.
Design/methodology/approach
The paper examines and identifies the lean efficiency gains achieved in the IGA project and highlights the synergies between BIM and lean concepts based on the facts and figures from the case study analysis. In complex projects, there is a vital need for a comprehensive approach that would enable successful managing of design and construction information via accurate modeling, collaboration and integration throughout the project lifecycles covering various disciplines.
Findings
The research findings in the paper make a significant impact in understanding the strategic perception for BIM as a new way of working methodology for the construction industry in Turkey, since the IGA project has become not only a key learning hub for the Turkish construction industry, but also a global landmark for digital construction and project delivery. In addition it proves the mutual synergies between BIM and lean practices.
Originality/value
The IGA project is a mega-scale airport construction project with features beyond building industry challenges, and it should be designed and constructed with tight deadlines and budgets and be operated afterwards in an effective and efficient way. Can lean and BIM help for timely and on-budget completion of the project and could they support the management of the airport facility after handover? The paper also discusses the lean and BIM implementation in the project in relation to the BIM Level 3 requirements.
