Lean construction (LC) is becoming prevalent, and assessment of the level of LC implementation is vital for organizations to realize their full potential. In meeting that need, lean construction maturity models (LCMMs) play a key role. However, there is less evidence of critical reviews in spite of the significant number of LCMMs available. Therefore, this study was initiated with the aim of systematically reviewing the literature on existing lean-construction-related maturity models (MMs) through a critical review. The study adopted the PRISMA method to review 24 such models using manual content analysis. The study revealed the most common attributes among the models, along with their key strengths and weaknesses. The findings of this study can be directly used to develop more robust LCMMs and enhance the knowledge base on theoretical underpinnings. From an industry perspective, the findings assist organizations to more effectively assess LC maturity. The study invites further research on the area of LC maturity and advocates for developing new MMs addressing these areas identified for improvement.

Purpose: The purpose of the paper is to propose a novel Green-BIM team (GBT) through a framework that would be essential in mitigating barriers to Green-BIM integration. Design/methodology/approach: An interpretive stance is adopted for this study. Through a qualitative survey, 25 experts with proficiency in green building construction and building information modelling (BIM) implementation were interviewed. Code-based content analysis was carried out using NVivo12. Findings: The findings of this study signified the need for a GBT and proposed architect, client, Green consultant, designer (mechanical, electrical and plumbing [MEP], structural), BIM coordinator, engineer (MEP, structural), project manager, quantity surveyor and facilities manager to be involved in the team representing design phase, construction phase and operational phase. Research limitations/implications: The experts were limited to the Sri Lankan context; however, the findings can also benefit countries with socio-economic and cultural backgrounds similar to Sri Lanka. Practical implications: Findings will be beneficial for policymakers and industry professionals to promote a BIM-enabled green building environment. The proposed GBT model extends existing theoretical frameworks, emphasising the need for a multi-disciplinary team throughout the entire lifecycle of a green building. Social implications: The proposed GBT model aligns with broader societal goals related to sustainable development. This approach provides a sustainable pathway to achieve economic goals for all stakeholders in the construction sector. Originality/value: There is a dearth of literature on a GBT to improve the construction of green buildings in Sri Lanka. Thus, the developed model is unique as it presents a novel GBT for the Sri Lankan construction sector. Further, it elaborates roles and responsibilities of team members with comprehensive details on how to mitigate the barriers to Green-BIM integration.

A maturity model is critical in analysing an entity as it evaluates the current situation and provides insights on enhancing the capabilities to reach higher maturity. Maturity models are being used in many industries and proven to have a positive impact on organisational development. Definition of a context specific maturity model is vital as it brings clarity to the model identification and better understanding relevant for a respective industry. Even though several construction maturity models exist, a clear and a comprehensive definition is not noticeable. A comprehensive definition for maturity models in construction sector would assist industry stakeholders to understand the components and key areas of construction maturity. Consequently, it would provide accurate and impactful results for construction firms to achieve higher maturity levels. Thus, the main aim of this paper is to establish a new definition for construction maturity models. In the process, the methodology included a systematic literature review adopting PRISMA literature review method and a content analysis using thematic analysis. The study analysed fifteen construction maturity models and identified nine overarching themes which were fundamental in developing the definition. The proposed definition would facilitate a better understanding among end users of construction maturity models, and it would assist the readers to distinguish it from other various models. Therefore, the derived definition would promote application of the concept of construction maturity in the industry. Further research could be conducted for diverse types of construction to enhance the effectiveness of the maturity models.

The growing need for urbanisation has resulted in the intense development of the construction industry, which has negatively impacted the conservation of the environment. In this regard, to preserve the ecosystems, the concept of sustainable development was introduced, however, the effectiveness of the existing sustainability practices in the construction industry is at a questionable level. Meanwhile, the evolving concept of biomimicry, which inspires and learns from natural processes, has proven the capacity to achieve sustainable parameters when incorporated into construction processes. Yet, there is a noticeable gap in applying the biomimicry concept to improve the sustainability of the construction industry. Therefore, this study aims to comprehend the applicability of the biomimicry concept in improving the sustainability of the construction industry. Accordingly, a comprehensive literature review was conducted on existing studies related to the biomimicry concept. The content analysis method was used to analyse the collected data. The findings suggested that the biomimicry concept can contribute to sustainable parameters such as material efficiency, energy efficiency and zero-waste concept. Accordingly, this study reveals the potential to improve the sustainability of the construction industry by comprehending the application of the biomimicry concept in detail. In this regard, the study discovers the enablers, barriers and strategies for biomimicry application in the construction industry. Accordingly, this study contributes to the theory and bridges the knowledge gap in utilising biomimicry applications to enhance the sustainability of the construction industry. It demonstrates how various biomimicry inspirations can positively impact sustainable parameters such as material efficiency, energy efficiency, and zero waste, thereby revealing the concept's applicability in developing a sustainable built environment.

The construction industry faces challenges in achieving efficiency, which has led to the adoption of Lean Construction principles. Defining a Lean Maturity Model specific to the construction context is essential for effectively implementing Lean principles. Prevailing evidence presents a significant gap in the existing literature regarding a consolidated and practically oriented definition of a Lean Construction Maturity Model (LCMM). While various frameworks have been proposed, there is a lack of consensus and a need for a unified understanding of Lean construction maturity. Thus, the paper is aimed at developing a definition for LCMMs through a systematic literature review using the PRISMA technique. The findings were analysed using the thematic analysis method. As per findings, a new definition was developed identifying nine key themes and corresponding sub-themes.As a theoretical contribution, this paper fills the existing literature gap by providing a precise and comprehensive definition. From an industry perspective, this makes a significant practical contribution to construction practitioners and policymakers by enabling organizations to assess their lean maturity level, identify areas for improvement, and strategically plan their lean transformation journey. The paper contributes to societal advancements by promoting efficiency, productivity, and sustainability in the construction industry through improving lean construction practices.
