Abstract
Purpose
Lean construction (LC) consists of very effective techniques; however, its implementation varies considerably from one industry to another. Although numerous lean initiatives do exist in the construction industry, the research topic related to LC implementation is still unexplored due to the scarcity of validated assessment frameworks. This study aims to provide the first attempt in developing a structural model for successful LC implementation.
Design/methodology/approach
This study developed a Lean construction model (LCM) by critically reviewing seven previous LC frameworks from different countries, defining 18 subprinciples grouped into 6 major principles and formulating testable hypotheses. The questionnaire was pre-tested with 12 construction management experts and revised by 4 specialized academics. A pilot study with 20 construction units enhanced content reliability. Data from 307 Moroccan construction companies were collected to develop a measurement model. SPSS V. 26 was used for Exploratory Factor Analysis, followed by confirmatory factor analysis using AMOS version 23. Finally, a structural equation model statistically assessed each construct's contribution to the success of LC implementation.
Findings
This work led to the development of an original LCM based on valid and reliable LC constructs, consisting of 18 measurement items grouped into 6 LC principles: Process Transparency, People involvement, Waste elimination, Planning and Continuous improvement, Client Focus and Material/information flow and pull. According to the structural model, LC implementation success is positively influenced by Planning and Scheduling/continuous improvement (β = 0.930), followed by Elimination of waste (β = 0.896). Process transparency ranks third (β = 0.858). The study demonstrates that all these factors are mutually complementary, highlighting a positive relationship between LC implementation success and the holistic application of all LC principles.
Originality/value
To the best of the authors’ knowledge, this study is the first attempt to develop a statistically proven model of LC based on structural equation modelling analysis, which is promising for stimulating construction practitioners and researchers for more empirical studies in different countries to obtain a more accurate reflection of LC implementation. Moreover, the paper proposes recommendations to help policymakers, academics and practitioners anticipate the key success drivers for more successful LC implementation.

Abstract
Purpose
Over the past two decades, the construction sector has experienced a surge in projects fueled by substantial government investment in infrastructure. However, amid this growth, the industry grapples with persistent challenges. Meeting project deadlines and budgets remains a struggle, impacting the industry’s credibility. Therefore, this research intends to investigate the idea of lean construction in the construction sector and look at the obstacles facing the construction industry in implementing lean construction strategies.
Design/methodology/approach
The insights presented here result from content analysis performed on 206 articles, while the metadata analysis is based on 891 publications.
Findings
This study highlights numerous important characteristics that influence an organization’s capacity to accomplish lean construction using a systematic literature review approach.
Research limitations/implications
For forthcoming research seeking validation, utilizing a mixed-method approach could prove advantageous. Yet, it is crucial to recognize the constraints of the present study, primarily centered on the scope of the literature review.
Practical implications
This assessment will enhance comprehension of the lean construction concept, potentially encouraging the adopting of lean construction practices. Moreover, it could provide insights into effectively applying these methods in practice.
Originality/value
The literature review highlights the necessity for organizations to identify and address potential challenges they might encounter in implementing lean construction. An essential step in overcoming these obstacles involves exploring the concept of lean construction within the sector and assessing the hurdles constraining the implementation of lean construction strategies in the construction industry.
