Abstract

Purpose

Increased waste during projects execution has led to time and cost overruns within the Zimbabwean construction projects industry. However, contextual barriers to lean construction implementation are yet to be established for derivation of effective remedies. The purpose of this paper is to report on a study that sought to determine barriers to lean construction implementation and assess the existence of statistically significant differences because of gender, designation and educational levels of respondents.

Design/methodology/approach

A questionnaire survey was administered on construction professionals for the collection of quantitative data. Factor analysis was used to reveal interrelated significant sets of barriers to lean construction implementation. Non-parametric statistical methods were also used to determine significant differences because of demographic variables.

Findings

Integration- and performance-related, human capital management–related, quality management–related barriers were determined as the highest-ranked of the nine significant components. Significant differences because of gender, designation and educational levels were non-existent for aggregated barriers, generally indicating consensus on the barriers. However, individual barriers showed inadequacies in management requirements for lean construction implementation from architects and those with diplomas and degrees.

Research limitations/implications

The determination of barriers establishes the knowledge for construction policy evaluation for enhanced performance of the construction industry. However, because of the exploratory nature of this study, the insights of clients were not considered.

Originality/value

Context-specific barriers to lean construction implementation were determined for consequent construction policy improvements in the construction industry.

Abstract

Purpose

This research seeks to evaluate the impact of applying lean construction principles on the performance of reinforcement operations using a discrete-event simulation (DES) approach.

Design/methodology/approach

Process mapping of reinforcements operations was first established through field observation and interviews with construction managers involved in the selected project. Subsequently, quantitative data were gathered and then used to identify the best probabilistic density functions for each activity duration based on the fit-quality tests. Upon testing the validity of the real-world model, a lean simulation model was developed, using ARENA software, to investigate the impact of lean construction principles on the performance of such processes.

Findings

Lean principles are effective in enhancing the performance of the selected construction process. Output performance measurements for real-world model and lean model revealed that lean construction principles led to 41% improvement in process productivity, 14% enhancement in process efficiency and 17% reduction in cycle time.

Research limitations/implications

The statistical findings only represent the process under study (reinforcement process) and cannot be generalized to other construction activities. In order to draw generalizable conclusions, future works are needed to extend this study to different project sizes and more complex construction processes (e.g. bricklaying process and concrete pouring operations). Moreover, there are other factors such as labor skills, rework and uncertainty, site conditions that require further analyses for leaner construction projects.

Originality/value

The methodology and the techniques presented in this work can be used for decision making by analyzing various lean construction scenarios and evaluating their impacts on performance outcomes of any construction process prior to real-world implementation.

Abstract

Purpose

The purpose of this paper is to identify and theoretically explain the general barriers to adopting lean construction practices in the construction industry regardless of the country or the company size or specialization, and to suggest future research studies in this field.

Design/methodology/approach

Systematic literature review was conducted to identify and explain the list of the barriers from scientific sources that were published before May 2018.

Findings

Twenty-nine barriers were identified and explained, and a proposed model to classify the sources of the barriers was chosen. Seventeen barriers were classified as internal environment-related barriers, five were labor-related, three were materials-related and four were exogenous barriers. In addition, some directions for the future research studies were suggested.

Research limitations/implications

The barriers that are related to the advanced levels of lean construction (LC) implementations, to a specific location or to a specific LC tool were excluded.

Originality/value

This review will help to increase the understanding of the new concept of LC and might help to encourage the adoption of LC practices. Also, it might be useful for identifying the strategies to achieve successful application of these practices.

Abstract

Purpose

Construction management is enriched in many ways by direct and indirect support of lean construction concept. The objectives of this study are to assess the current level of awareness about lean construction practice, to identify the potential benefits and challenges to implement lean construction in the Bangladeshi construction industry and to prioritize them.

Design/methodology/approach

A comprehensive literature review has been done to design a questionnaire for the survey. The final questionnaire has been designed with 27 lean tools, 41 challenges, and seven benefits of implementing lean principles in the construction industry. A total of 164 valid responses have been collected from Bangladeshi construction practitioners involved in different types of construction organizations. The result has been analyzed by Relative Important Index (RII).

Findings

The findings revealed 41 challenges to implement lean construction with seven benefits in the Bangladeshi construction industry. The result shows that an appreciable number of respondent familiar with the techniques of lean construction but they don't practice. The findings have also pointed out that the lean construction approach adds a positive impact especially on quality, safety, cost, productivity, and environmental level. The top-ranked challenges to implementing lean construction are: lack of awareness and skill, poor management, traditional culture and attitude of employees, inadequate resources and equipment and nonuse of modern techniques and technologies.

Originality/value

This study reveals real scenario of lean construction in Bangladesh. It contributes to the body of knowledge, as it uncovers for the first time the awareness level, benefits and challenges to implement lean construction with reference to the social, economic and cultural context of Bangladesh. Exploring the findings, the study could help the stakeholders, construction firms, academician, researchers and government to focus their effort and resources on the significantly appropriate issues. Again, the study may be beneficial to developing countries especially in South Asia which share the same socio-economic status with Bangladesh.

Abstract

Purpose

The purpose of the paper is to investigate the critical success factors (CSFs) associated with the effectiveness of transfer and sharing of tacit knowledge in lean and agile construction processes.

Design/methodology/approach

The study identifies ten CSFs that initiate the transferring and sharing of tacit knowledge. The CSFs are validated through quantitative study. This study recruited project managers, executives, consultants and other managers that are directly involved in the management of a construction project. It recruits the respondents those have background and experience from disciplines such as lean construction, agile construction, construction supply chain (CSC) and knowledge management in lean, agile and CSC. The data collected through self-administrative questionnaire are categorised as ordinal data to analyse in SPSS with frequency and Kruskal–Wallis H test, Spearman’s correlation analysis and a rank-order analysis is done to establish the level of importance of those factors.

Findings

Initially, “Trust between construction organisations” is identified as the foremost CSF. Moreover, other CSFs such as motivation, leadership capabilities, business strategies and organisational capabilities follow trust.

Originality/value

This is the first study that investigates and establishes the CSFs that are essential to initiate transferring and sharing tacit knowledge in a lean and in an agile construction processes.

Abstract

Purpose

Increasing demand for the best value for client’s money necessitates waste reduction while enhancing the project functionality in construction industry. The purpose of this paper is to propose Lean integrated Value Engineering (LiVE) approach by establishing the synergy between Lean and Value Engineering (VE) concepts for construction industry.

Design/methodology/approach

A literature survey and in-depth un-structured interviews with six subject matter experts in three steps were used to investigate the synergy between Lean principles and VE job plan to develop LiVE approach for the construction industry. The gathered data were analysed using code-based content analysis and the LiVE approach was finally validated using interviews by two additional subject matter experts representing industry and academia.

Findings

Research findings established that there is a synergy between Lean principles and VE job plan. Accordingly, the study developed a LiVE approach, which specify client’s value, identify the value stream, make value flow without interruption, let the client pull functional requirements and pursue perfection during “value establishment”, “value analysis of functional requirements”, “value creativity”, “value evaluation”, “value development”, “value verification” and “value achievement” phases.

Originality/value

The novel LiVE approach will guide construction industry practitioners on how to integrate Lean concept with VE in order to reduce unnecessary costs and wastes, to enhance project functionality and ultimately to achieve value for client’s money.

Abstract

Purpose

The purpose of this paper is to develop a framework for implementing lean construction and consequently to improve performance levels in the construction industry in the context of Saudi Arabia. There is currently no framework for implementing lean construction specifically tailored to the Kingdom of Saudi Arabia (KSA) construction industry. Existing lean construction frameworks are focussed on other countries and are less applicable in the KSA due to differences in socio-cultural and operational contexts.

Design/methodology/approach

This study employs the interpretive structural modelling (ISM) technique for data collection and analysis. First, following a survey of 282 construction professionals, 12 critical success factors (CSFs) for implementing lean construction in the KSA construction industry were identified by Sarhan et al. (2016). Second, 16 of these professionals who have 15 years or more experience were exclusively selected to examine the contextual relationship among the 12 CSFs. A row and column questionnaire was used for a pairwise comparison of the CSFs. A matrix of cross-impact multiplications (MICMAC) was applied to analyse the questionnaire data to develop an ISM model that can serve as a framework for implementing lean construction. Third, the framework was subjected to further validation by interviewing five experts to check for conceptual inconsistencies and to confirm the applicability of the framework in the context of the KSA construction industry.

Findings

The findings reveal that the CSFs are divided into four clusters: autonomous, linkage, dependent and driving clusters. Additionally, the findings reveal seven hierarchies of inter-relationships among the CSFs. The order of practical application of the CSFs descends from the seventh hierarchy to the first hierarchy.

Originality/value

The new framework is a significant advancement over existing lean construction frameworks as it employs an ISM technique to specify the hierarchical relationships among the different factors that contribute to the successful implementation of lean construction. The primary value of this study is the development of a new framework that reflects the socio-cultural and operational contexts in the KSA construction industry and can guide the successful implementation of lean construction. Therefore, construction industry operators such as contractors, consultants, government departments and professionals can rely on the framework to implement lean construction more effectively and successfully.

Abstract

Purpose

Construction management is ameliorated by the lean construction concept in many direct and indirect ways to reduce waste of construction process and improve the value. The purpose of this paper is to identify the challenges of the implementation of lean construction in the Bangladeshi construction industry and to prioritize these factors that constitute these challenges.

Design/methodology/approach

A comprehensive literature review was used for shorting the global challenges of implementing lean construction. Subsequently, these challenges were incorporated into a structured questionnaire for survey. A total of 164 valid responses were collected from Bangladeshi construction practitioners involved in different types of construction organizations. The results were analyzed using the Relative Important Index (RII) and Mann–Whitney U test.

Findings

The findings revealed 41 challenges of lean construction implementation in the Bangladeshi construction industry. The highest ranking challenges are the lack of awareness about lean construction, lack of skills, training and lean techniques, unwillingness to change the existing culture, lack of management commitment, fragmented and cyclic nature of the construction project and unavailing communication between all project participants. The study also discusses some universally applicable solutions to overcome these challenges.

Originality/value

By the findings of this study, the Bangladeshi construction industry could get a new insight into the challenges of implementing lean construction. It could play a very important part in the body of knowledge, as it reveals the challenges of implementing lean construction for the first time with the socio-economic context of Bangladesh. Exploring the findings, the study could help the stakeholders, companies, academician, researchers and government to focus their effort and resources on the significantly appropriate issues. Furthermore, this study may beneficial to those developing countries especially in South Asia, who have shared the same socio-economic status with Bangladesh.

Abstract

Purpose

The purpose of this study is to propose a conceptual framework for the exploration of appropriate lean techniques applicable to medium and large construction companies and measure their impact on the competitiveness and economic performance of construction companies in United Arab Emirates.

Design/methodology/approach

A questionnaire survey is conducted on 215 construction professionals in UAE to investigate the lean technique’s effect on the construction companies’ performance. The data collected were analyzed with SPSS 20.0 version software using the Cronbach’s a reliability test, correlation coefficient test and Kaiser–Meyer–Olkin test.

Findings

Analysis of lean techniques in the construction industry reveals 21 lean techniques. These techniques were categorized into the six types of lean core values. Process focus was found to be the most applied type of construction core value in the surveyed companies. This is required to focus on applying other core values as it will impact the company’s economic performance positively.

Research limitations/implications

The integrity of the research findings is based on the accuracy and reliability of collected data from 215 respondents working for construction companies in UAE, implementing lean construction techniques within a their daily activates and not achieving significant project achievements in terms of quality improvement, speed and cost reduction without adopting the overall lean construction framework.

Practical implications

This research recommends a systematic approach for the implementation of the anticipated framework within a cyclical look-ahead period and emphasizes the practical implications of the proposed approach in the construction companies.

Originality/value

Research significance emphasizes increasing the effectiveness of the construction industry and influences the development of lean construction framework, which improves lean construction practices using the lean techniques. This contributes to the effort of applying lean techniques in the construction industry. Limited studies have been done in the construction industry, mainly in UAE, compared to lean manufacturing.

Abstract

Purpose

Better integration of project processes has often been identified as the key issue regarding construction performance improvement. In some countries lean construction has become well‐established, although there appears to be considerable diversity in the interpretation of the concept. Lean construction initially focused on production aspects, but gradually design issues have started to receive more attention and integrating construction design and production processes from a lean perspective are beginning to be addressed. The purpose of this paper is to identify some of the practical challenges underlying the implementation of approaches promoted as “lean” and compare this with published research/theory.

Design/methodology/approach

Following an extensive review of the literature, a multiple case‐strategy approach was used to explore the practical application of lean approaches to design and construction integration in an organisational setting. Summaries of the case studies, one from the USA and two from Denmark, help to highlight a number of pertinent issues facing practitioners and researchers.

Findings

Findings suggest that it is possible to identify a number of aspects that (in theory as well as in practice) both influence and, to various extents, limit the applicability of the lean philosophy to construction. Findings also help to emphasise the importance of a number of interdependent factors for achieving better integration, namely: value identification/specification; an appropriate project delivery framework; structuring and planning of delivery processes; transparency; management and leadership; learning; and the importance of local context.

Originality/value

The findings provide an original contribution to the integration of design and construction activities from a lean perspective. The findings are generic and could be practically applied in a variety of contexts.
