PurposeThe study aims to test, measure and quantify the impacts of lean construction and BIM implementation on flow in construction projects.Design/methodology/approachDetailed control data from a set of 18 high-rise residential construction projects executed between years 2011 and 2020 were analyzed using the construction flow index (CFI), a measure of workflow quality. Seven comparable projects with a diverse range of LPS, BIM, VDC and 5S implementation were selected to compare the impacts of these innovations on flow.FindingsImplementing BIM in the big room and applying the last planner system and other lean construction techniques increased the CFI from 4.31 to 8.12 (on a 10-point scale). Avoiding trades crossing one another's paths between tasks was the most significant aspect of improved flow. Moreover, the benefits of implementing lean practices with BIM or VDC were found to be measurably greater than when these approaches were implemented separately.Research limitations/implicationsThe primary limitation of the study is that the degree of confidence in the results is limited by the nature of the case study approach. Although 18 is a respectable number of case study projects, it cannot offer the degree of confidence that a broader, representative sample of projects could. Similarly, the case studies are all drawn from the same construction context (residential apartments) and the same geographic region, which necessarily limits confidence concerning the degree to which the findings can be generalized.Originality/valueThe research is the first of its kind to quantitatively assess the impacts of BIM and lean construction on flow. Use of the CFI to quantify flow quality also highlights the potential value of CFI in providing project managers and planners a clear view of the smoothness or irregularity of flow and of differences between subcontractors' production rates.

PurposeThis study aims to investigate and model the complex dynamics of innovation enablers in construction projects aiming to develop a framework identifying actions for clients to promote innovation.Design/methodology/approachThrough a comprehensive literature review, a conceptual model was previously derived to explain the client-driven enablers in promoting innovation. This was tested using the data from 131 Australian construction projects. Statistical analysis was conducted on the data using factor analysis and correlation analysis to test the model, which was validated using the case study approach. The testing and validating aspects are explained in this paper.FindingsThe constructs of the recommended model are idea harnessing, relationship enhancement, incentivization and project team fitness.Research limitations/implicationsThe difficulty of analyzing the complex dynamics happening within projects in relation to innovation has been a barrier to progress research in this area. The introduction of this model would pave the way for researchers to explore this area with ease.Originality/valueAs revealed in the detailed literature review undertaken, this is the first time that a comprehensive study has been conducted to identify client-led innovation enablers for construction projects. The results would benefit industry practitioners to achieve enhanced project outcomes in construction projects through innovation.

The Status

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.

PurposeHigh-level labor waste is a major challenge in construction projects. This paper aims to identify, quantify and categorize labor waste in the context of Iranian housing construction projects.Design/methodology/approachThis research uses a case study approach, with empirical data collected through direct observations and semi-structured interviews.FindingsHaving triangulated the findings from the literature review and empirical studies, a list of eight types of waste was derived for the thirteen observed laborers in ten case study projects. The empirical studies allowed the labor waste identified from the literature to be verified and refined by considering it in the context of the observed activities, and led to two new types of waste being identified which were not considered in the literature. Findings indicate that nearly 62% of laborers' time is spent on non-value-adding activities. It appeared that “unnecessary movement,” “waiting” and “indirect work” make up the highest labor waste.Research limitations/implicationsThis research focuses only on onsite resource flows in a housing construction site. It does not include offsite flows such as material delivery to site.Originality/valueThe findings have provided substantial evidence on type and amount of labor waste and provide a solid basis to stimulate construction actors to participate in reducing labor waste and improving productivity.

Lean Principles

Purpose Previous research shows that implementing lean construction is not a straightforward task. The purpose of this paper is to examine the role of formal and informal mechanisms in implementing lean principles in construction projects. Design/methodology/approach The paper draws on a single case study of the implementation of innovative lean principles in a public construction project in Norway. The study is based on qualitative data, including 17 semi-structured interviews with 21 individuals, document analysis, and observations in meetings and seminars, in addition to informal conversations. Findings Formal mechanisms, including contractual arrangements, have the potential to both facilitate and hamper the implementation of innovative lean principles in a construction project. They might create coherence, but at the same time they might limit the scope of the concept in such a way that others do not accept it. Informal mechanisms, including social and lateral relationships and trust aid implementation, both directly by creating commitment and by modifying the challenges that the formal mechanisms potentially incur. Formal mechanisms may, in turn, nurture the informal ones. Research limitations/implications The research is based on a single case study within the Norwegian public sector, which is dependent on specific public procurement regulations and subject to strong contractual traditions. Originality/value The research extends the existing knowledge of implementation of lean construction in the construction industry. It helps refining the understanding of the role played by formal and informal mechanisms, and the interplay between them in the implementation process. This knowledge is also relevant for process innovations in construction in general.

The Ideal

Purpose Materials supply is one of the important elements in construction operation and a major factor affecting the quality of construction projects. Many industries look to manage materials effectively by attempting to integrate logistics processes into logistics chains of suppliers and customers. Logistics processes, being crucial for successful completion of construction projects, but in fact, auxiliary, are often entrusted to external professionals specialised in logistic services, such as logistics centres. However, this tendency is yet to be developed in construction. The purpose of this paper is to develop a simulation framework for the examination of potential improvements of logistics performance using logistics centres. Design/methodology/approach A case study approach was adopted with computer simulation using Flexsim. Data of vehicle movements were collected during construction on-site from the start of construction to “hand-over” to the building owner. Findings The ideal location of a logistics centre is identified using vehicle movements data collected on the site. The potential improvements of the planned centre are then evaluated by simulating various scenarios of vehicle movements. The enclosed results from the simulations indicate that using a logistics centre will reduce waste for the construction project considered. Originality/value The paper emphasises that creating a logistics centre for a project can improve construction logistics performance, by consolidating and optimizing both off-site and on-site logistics, especially when the site condition is prohibitive (small footprint with limited loading bay area). Establishing logistics centres may help find ways of making the overall construction project more effective by improving the management of materials.

Purpose The purpose of this paper is to discuss the role of digital forensics in an evolving environment of cyber laws giving attention to Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) countries, comprising Bangladesh, India, Myanmar, Sri Lanka, Thailand, Nepal and Bhutan, in a dynamic global context. Design/methodology/approach This study uses a case study approach to discuss the digital forensics and cyber laws of BIMSTEC countries. The objective of the study was expected to be achieved by referring to decided cases in different jurisdictions. Cyber laws of BIMSTEC countries were studied for the purpose of this study. Findings The analysis revealed that BIMSTEC countries are required to amend legislation to support the growth of information technology. Most of the legislation are 10-15 years old and have not been amended to resolve issues on cyber jurisdictions. Research limitations/implications This study was limited to the members of the BIMSTEC. Originality/value This paper is an original work done by the authors who have discussed the issues of conducting investigations with respect to digital crimes in a rapidly changing environment of information technology and deficient legal frameworks.

Purpose The effective management of inter-organizational integration is central to complex projects. Such projects pose significant challenges for integration, as organizations struggle with constantly changing inter-organizational interdependencies and must develop and adapt integration mechanisms to meet new demands. The purpose of this paper is to understand what kinds of integration mechanisms are used and how they are developed and adjusted during the infrastructure alliance projects. Design/methodology/approach This study provides empirical evidence of integration dynamics in project alliancing by analyzing two infrastructure alliance projects – a complex tunnel construction project and a railway renovation project. The research approach is an inductive case study. Findings This paper identifies integration mechanisms adopted in two case projects and three central triggers that led to changes in the integration mechanisms: project lifecycle phase, unexpected events and project team’s learning during the project. Practical implications Integration capability should be a precondition for alliance project organizations and requires the adoption of a wide range of integration mechanisms, as well as an ability to adjust those mechanisms in response to everyday dynamics and emergent situations. Originality/value Although unplanned contingencies and the responses to them represent important influences in organizations, there is limited amount of research on the dynamics of integration. The findings will be of value in supporting the management of inter-organizational integration in complex, uncertain and time-critical construction projects.

Study Approach

Purpose – This study aims to explore the phenomenon of training engagement from the trainers’ perspective. Specifically, two questions guided this inquiry. First, how do trainers define engagement in the training context? and What strategies do trainers use to engage trainees? Design/methodology/approach – The collective case study approach was adopted for this qualitative study. Seven cases were selected for in-depth analyses. Data were collected through individual, face-to-face interviews and analyzed using the constant comparative analysis method. Findings – Major findings suggest that engaging training practices take various forms. They include being trainee-centered, maximizing learning through entertaining and interesting instruction, accommodating different learning styles, eliciting trainee participation by creating an encouraging learning environment and connecting with trainees by building rapport early in a training session. Research limitations/implications – The small sample limits the generalizability of the findings. However, this study expands training literature by focusing on an under-explored research area, the role of engaging trainees in maximizing learning outcomes. Practical implications – For trainers, this study offered some specific strategies they can use to engage learners in the training context to achieve desired learning outcomes. In addition, the seven cases selected for this study may be used as a benchmark against which both experienced and novice trainers compared their own practices. Originality/value – This is one of very few qualitative studies with a focus on emotional aspects involved in training. The rich data from this study shed light on areas for future improvement, particularly regarding how to effectively engage trainees to maximize learning outcomes.

The Impact

Purpose – This paper aims to to explore power and legitimacy in the entrepreneurship education classroom by using Pierre Bourdieu’s sociological and educational theories. It highlights the pedagogic authority invested in educators and how this may be influenced by their assumptions about the nature of entrepreneurship. It questions the role of educators as disinterested experts, exploring how power and gendered legitimacy “play out” in staff–student relationships and female students’ responses to this. Design/methodology/approach – A multiple-method, qualitative case study approach is taken, concentrating on a depth of focus in one UK’s higher education institution (HEI) and on the experiences, attitudes and classroom practices of staff and students in that institution. The interviews, with an educator and two students, represent a self-contained story within the more complex story of the case study. Findings – The interviewees’ conceptualization of entrepreneurship is underpinned by acceptance of gendered norms, and both students and staff misrecognize the masculinization of entrepreneurship discourses that they encounter as natural and unquestionable. This increases our understanding of symbolic violence as a theoretical construct that can have real-world consequences. Originality/value – The paper makes a number of theoretical and empirical contributions. It addresses an important gap in the literature, as educators and the impact of their attitudes and perceptions on teaching and learning are rarely subjects of inquiry. It also addresses gaps and silences in understandings of the gendered implications of HE entrepreneurship education more generally and how students respond to the institutional arbitration of wider cultural norms surrounding entrepreneurship. In doing so, it challenges assertions that Bourdieu’s theories are too abstract to have any empirical value, by bridging the gap between symbolic violence as a theory and its manifestation in teaching and learning practices.
