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.

PurposeWhile a considerable amount of research has been conducted on construction disputes, disputes remain prevalent in the construction industry and have still been a crucial problem in the Turkish construction industry as well. The purpose of this paper is to explore the perceptions of different stakeholders on key factors that contribute to construction disputes by adopting a qualitative approach.Design/methodology/approachThe qualitative approach adopted for the study provided gathering in-depth and rich information about the topic. To explore the phenomenon in-depth information, semi-structured interviews were conducted. A total of 38 interviews were conducted among experts and practitioners who engaged in construction disputes.FindingsContent analysis of interview data resulted in the emergence of varying categories relevant to the problems which result in construction disputes. By grouping related themes into main categories, the analysis yielded five major ones: clarity of the contract form, errors in contract documents, payments, changes, delays and not granting extension of time.Research limitations/implicationsThe major limitations are having interviewees from one country and results limited to the Turkish construction industry.Practical implicationsThe findings provide insight on the factors contributing to construction disputes as perceived by different stakeholders, which should provide guidance to determine the associated risks for dispute occurrence, make effort to mitigate disputes once they happen, take proper precautions for minimizing the effects and after all make a significant contribution in the successful accomplishment of completed construction projects.Originality/valueThe findings of the study contribute to a deeper understanding of the factors contributing to construction disputes through a qualitative approach which is limited in the related literature. Although the qualitative exploration only focuses on the Turkish construction industry, the study has added significantly to the body of knowledge within the subject area.

Purpose The purpose of this paper is to identify the barriers to implementing lean construction in the Kingdom of Saudi Arabia (KSA) construction industry and to prioritise the principal factors that constitute these barriers. Design/methodology/approach A literature review was initially used to reveal the global barriers to implementing lean construction. Subsequently, these barriers were incorporated into a structured questionnaire, and a convenience sample of 282 construction professionals in the KSA construction industry was surveyed. The results were analysed using mean item score (MIS), Mann–Whitney U test and principal component analysis (PCA). Findings The findings revealed 22 barriers to lean construction implementation in the KSA construction industry. Principal factors that constitute these barriers were found to be traditional practices, client related, technological, performance and knowledge and cost-related barriers in descending order of pervasiveness. The study also proposes solutions to overcome these principal barriers. Originality/value This study provides a global overview of the barriers to implementing lean construction. It contributes to the body of knowledge, as it uncovers for the first time the barriers to implementing lean construction in the KSA construction industry with reference to the socio-cultural, economic and operational context of the KSA. Thus, it is relevant to other countries in the Middle East because of their shared similarities to the KSA. Furthermore, the solutions proposed to overcome these barriers in the KSA construction industry can be applied in other countries where similar barriers are identified.

Purpose Tender price remains an imperative parameter for clients in deciding whether to invest in a construction project, and it serves as a basis for tender price index (TPI) manipulations. This paper aims to examine the factors affecting tender price in the construction industry. Design/methodology/approach Based on the literature review, nine independent constructs and one dependent construct relating to tender pricing were identified. A structured questionnaire survey was conducted among quantity surveyors in Ghana. Partial least squares structural equation modelling (PLS-SEM) examined the influences of various constructs on tender price development (TPD) and the relationships among TPD and TPI. Findings Results showed that cultural attributes, client attributes, contractor attributes; contract procedures and procurement methods; consultant and design team; external factors and market conditions; project attributes; sustainable and technological attributes; and TPI have a positive influence on tender price, whereas fraudulent attributes exert a negative influence. Practical implications The findings offer construction professionals broader understanding of factors that affect tender pricing. The results may be used in professional decision-making in the pricing of construction projects, as they offer clearer causal relations between how each construct will influence pricing. Originality/value This study adds to the body of construction pricing knowledge by establishing the relationships and degree of influences of various factors on tender price. These findings provide a valuable reference for practitioners.

Purpose The decentralisation of information and high rate of mobile content access in the construction industry provide an ideal scenario for improvement of processes via the implementation of the paradigm of the Internet of Things (IoT). Smart devices are considered as the objects interconnected in the IoT; therefore, they play a fundamental role in the digital transformation of the construction industry. Currently, there is a lack of guidelines regarding the implementation of smart devices for digitalisation in the construction industry. Consequently, this paper aims to provide a set of guidelines for implementing smart devices in the construction industry. Design/methodology/approach An empirical study was performed in the UK and the Dominican Republic (DR). Following a systematic approach, qualitative data collection and analysis was performed based on semi-structured interviews involving professionals from construction companies in the UK and the DR. Interviews were recorded and subsequently transcribed using Microsoft Word and exported to the software NVivo, where the software was used to find common thematic nodes across all interviews. Findings The findings encompass drivers, challenges and critical success factors (CSFs) for implementing smart devices in construction project. For both countries, the top five CSFs were leadership, staff training, culture, technology awareness and cost of implementation. These findings were used to develop a strategic framework for implementing smart devices in construction companies. The framework establishes the actors, elements and actions to be considered by construction companies when implementing smart devices. Originality/value This paper provides a richer insight into the understanding and awareness of implementing smart devices. A strategic framework for implementing smart devices in the construction industry and providing guidelines for adopting smart devices in construction projects was developed and validated. This study provides a better understanding of the key factors to be considered by construction companies when embedding smart devices into their projects.

PurposeConstruction 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/approachA 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).FindingsThe 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/valueThis 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.

PurposeThough the Public Procurement Act of Ghana makes room for specific socio-economic policies (environmental, social, economic and other policies which are intended to promote social and economic impact), there is no explicit definition and provision for social value as an evaluation criterion, culminating in the absence of a definition in the Act. This paper elicits the conception and understanding of social value from stakeholders in the Ghanaian construction industry.Design/methodology/approachThe study adopted a qualitative method that relied on a semi-structured interview of 30 participants purposively drawn from Western, Western North and Central regions of Ghana. An inductive thematic analysis approach, which involved identifying repetitions, exploring similarities and differences, noting linguistic connectors, and a framework were employed to analyse the data.FindingsThe study established no single definition or explanation for social value in the construction industry in Ghana. However, it was revealed from the study that the concept of social value could be defined from the functional perspective of the definer, particularly from the perspective of a Procurement Officer, Works Engineer, and a Quantity Surveyor. A new insight from the study that differs from the body of literature is that participants equated benefits derived from physically constructed projects as social value.Social implicationsThe study has implication for public administration and practice regarding the decision-making process in the construction industry in Ghana. It provides a vital awakening on social value as a criterion in evaluating construction works procurement in Ghana. The ability of participants to equate the benefits derived from executed construction projects as social value creates a new perspective on understanding the meaning of social value in the procurement of works construction.Originality/valueThe study contributes to the state-of-the-art and ongoing discourse on the concept of social value globally. The findings create an important catalyst for social value research in the Ghanaian construction industry.

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.

Purpose – The users of construction technologies such as builders and trades people have been acknowledged as sources of potentially important innovations. These innovations may be in the form of safer, less labour intensive, or cheaper methods and processes. The purpose of this paper is to assess whether the Australian construction industry is providing an environment where user-based innovation is being supported and implemented. Design/methodology/approach – An explorative study was undertaken to provide an insight into actual experiences of the implementation of user-based innovation. The data were collected through face-to-face semi-structured interviews providing case studies on multiple aspects of the implementation of innovative construction technologies. The cases involved a cross section of advances, including product, tool, and system technologies. Findings – The main motivation behind developing the technologies was problem solving. The associated industries of manufacturing and retail, as well as consultants within the construction industry present the greatest barriers to implementation. Originality/value – This research provides a better understanding of the factors that are preventing the successful implementation of user-based innovative construction technologies in small firms.

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.

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.
