Purpose – The purpose of this paper is twofold. First, it aims to highlight the main factors and items affecting the productivity of construction projects, based on the perceptions of CEOs in construction companies in Iran. Second, the study compares the elicited CEOs’ perceptions against the findings of studies based on the views of such as project managers, middle managers and employees in other levels. Design/methodology/approach – The study drew upon literature on construction work to develop a conceptual model. Further, a total of 60 CEOs from road construction companies were surveyed using a five-point Likert scale questionnaire to generate the data. The collated data were categorised and ranked according to the CEOs perceived level of importance using the relative importance index. Findings – The findings highlight the main factors and items affecting labour productivity in construction projects in Iran as perceived by CEOs, which are mainly of human resources management nature and could be attributed to motivation and managerial policy aspects. The study also recognises that factors associated with the working environment particularly safety and health are perceived as insignificant by Iranian CEOs which could be a concern for the Iranian construction industry. The discussions shed some light on the discrepancies between the perceptions of CEOs and previous studies in regards to major determinants of productivity in the construction context. Originality/value – This study is the first study aiming at discussing the perceptions of CEOs of construction companies active in construction projects in Iran. As such, the study highlights the standpoint of the main decision makers in construction companies in regards to labour productivity in the construction sector. Thus, the key contribution of the present study is providing insight into the perceptions of CEOs, who play the most vital role in strategic development of construction companies whereas previous studies have mostly focused on project or middle managers having a lower influence in determining the strategic plans of companies.

Purpose The purpose of this paper is to develop a motivation framework that will enhance labour productivity for Iskandar Malaysia (IM) construction projects. The vision of IM development corridor is to become Southern Peninsular Malaysia’s most developed region by the year 2025. IM cannot realise this foresight without effective labour productivity. Previous studies have reported that the labour productivity of IM construction projects was six times lower than the labour productivity of Singapore construction projects, due to lack of motivation among IM labourers, and a shortage of local skilled labour. Therefore, there is a need to study how to motivate IM construction labourers, so as to increase their productivity. Design/methodology/approach A quantitative research method was used to collect data from IM construction skilled labourers and construction professionals, using two sets of questionnaire. The respondents were selected using a purposive sampling technique. In total, 40 skilled labourers and 50 construction professionals responded to the questionnaire survey, and the data were analysed using Statistical Package for Social Science software (version 22). Findings The analysis revealed the major factors that motivate labourers participating in IM construction projects. The factors were ranked hierarchically using Relative Importance Index (RII) and the outcome of the ranking indicated that effective management, viable construction practices, financial incentives, continuous training and development, and safe working environment were the most significant motivation strategies that positively influence IM construction labourers. Originality/value The study developed and validated a framework that can be used to boost the morale of IM construction labourers, so that their productivity can be increased. Implementation of the established motivation framework will also lead to career progression of IM construction labourers, based on the training elements in the framework. This career prospect will attract local skilled labourers to participate in IM construction projects.

Purpose The purpose of this paper is to identify the factors that affect TQM implementation in construction companies and it suggests solutions for TQM implementation in a difficult environment. Design/methodology/approach Studies were carried out at six large construction companies who ply their trade in Southern Africa and in-depth investigations were conducted to assess TQM implementation practices and associated TQM barriers. Interviews were conducted on directors and key personnel that play important roles in TQM implementation in their respective organisations. The empirical study also utilised a number of organisational documents which added rigour to the findings. Findings This study identified three core categories and ten main barriers affecting TQM implementation in Southern Africa construction companies. The core categories are motivation, infrastructure and penchants and tendencies while the factors are lack of quality support, poor TQM knowledge and TQM awareness, poor information sharing, temporary workers, overdependence on contract document, poor data collection measurement, undefined TQM roles and responsibilities, award to lowest bidder tendency, poor business environment and corruption. Research limitations/implications The study was conducted based on companies plying their trade in Southern Africa and mostly around Malawi, Zambia and Mozambique. It does not study companies in Namibia, Zimbabwe, Angola, South Africa and Botswana. Practical implications TQM cannot be exported wholly from another region to a new setting without taking into consideration the local factors associated with that setting. For successful TQM implementation in construction in Southern Africa, characteristics of this region have to be known. This study illuminates a number of TQM implementation barriers associated with construction especially applied to this difficult environment. Application of this knowledge would enhance TQM and heighten competitive advantage initiatives. The proportions highlighted in this study therefore help build up the TQM implementation awareness. Social implications At society level, the findings of this study indicate societal problems such as corruption and business environment which require wide level approaches to deal with these barriers. In addition, if TQM applied in road construction projects, the quality of the roads will be improved, this in turn will have direct impact on quality of life in the society, better roads means easier access to hospitals, schools and public places, better transport and movements of goods and services, etc. It can also save money for the country in long run and economic benefits to the society. Originality/value The factors identified in this study are based on current TQM implementation practices at established construction companies in Southern Africa. They provide a practical basis for guiding TQM in construction companies operating in difficult environments.

PurposeWhile operational factors reduce construction workers' productivity in Zimbabwe, the impact of the people-centred management aspects has not been empirically interrogated as a remedy. This article reports on a study that sought to determine significant people-centred management aspects that lead to improved labour productivity and assesses the existence of statistically significant differences due to the demographic variables of respondents. Demographic-specific strategies that enhance construction “workers” productivity were revealed.Design/methodology/approachThe survey research design using a self-administered questionnaire was deployed to collect the primary data. The design followed a positivist paradigm to evaluate objectively how people-centred management affects construction workers' productivity. The statistical data were descriptively and inferentially analysed.FindingsPeople-centred management was determined to be significant in improving construction workers' productivity, with the most significant aspect being the building of employee confidence in related approaches. Designations and educational levels mostly indicated a statistically significant difference in several aspects that included the adoption of a functional reward culture for workers and training on people-centred principles. Training on-site management and construction workers in people-centred management and its application are crucial to improving construction workers' productivity.Research limitations/implicationsConstruction companies should drastically improve their concern for people while they sustain a high concern for production within their construction sites. Although several factors affect construction workers' productivity, this study determined that management-related factors and people-centred management were significant towards influencing low productivity in Zimbabwe.Originality/valueThe study determined people-centred management and demographic-specific interventions as being able to improve construction workers' productivity in Zimbabwe.

Purpose This paper aims to investigate the application of lean construction (LC) techniques in reducing accidents in construction projects. Design/methodology/approach A quantitative approach was used to collect the required data using a questionnaire survey and descriptive analysis was used to analyse the collected data. The LC techniques that were investigated in this paper are related to the tools of the last planner system (LPS), increased visualisation (IV), 5S, error-proofing, daily huddle meetings (DHMs), first-run studies (FRS), continuous improvement (Kaizen) and accident investigation (5Whys). Findings The overall results indicated that LC techniques are poorly implemented in construction projects in the Gaza Strip. The top three LC tools used to reduce the causes of accidents in the Gaza construction projects were 5Whys, 5S and LPS, while the highest three LC techniques applied to reduce the causes of accidents that were applicable were cleaning the workplace and removing materials and machines that are not required; conducting accident investigation and root cause analysis programmes; and using safety signs and labels on site. Research limitations/implications There is a lack of information and published studies regarding the links between LC and safety, especially in the Middle East. This paper is limited to the perceptions and geographical boundaries; therefore, it cannot be generalised. However, it could form the basis for useful comparison in the future. Triangulation research method could also be used in future research to minimise the bias and validate the conclusions. Practical implications The findings of this paper will stress professionals and construction companies in Gaza to reconsider their behaviour towards using LC techniques. The findings of this paper will aid them to shift their attention and resources towards including LC techniques in their plans to reduce the causes of accidents on construction sites. Social implications The findings of this paper will encourage professionals and construction companies in Gaza to reconsider their behaviour towards using LC techniques. The findings will also aid them to shift their attention and resources towards including LC techniques in their plans to reduce and/or avoid the causes of accidents on construction. Originality/value Because of the lack of published works that are specific to the Middle East, the authors believe that the originality lies in the paper’s serious attempt to explore the application level of the LC concept to safety in this part of the world. This paper contributes to a better understanding of the applicability of LC techniques in terms of accidents reduction. Findings from this paper provide a clear picture of the current status of using LC techniques to reduce accidents in the Gazan construction projects which drive them to investigate the main barriers and try to overcome them.

PurposeThe UK construction industry produces up to one third of all waste to landfill. This study aims to identify specific project practices impeding the reduction of waste in construction projects as well as uncovering potential waste solutions throughout the project delivery process. The rationale being that for such a drastic reduction in waste to landfill, holistic and extensive measures would be required.Design/methodology/approachA two‐way methodological approach was used. This comprised qualitative unstructured interviews and a quantitative questionnaire survey of three major stakeholders in the UK construction industry: clients, architects and contractors.FindingsDesign factors remain the major cause of impediments to waste reduction to landfill. Critical impediments include clients making waste prevention a top priority in projects, overly complex designs, waste taking a low priority compared to project time and costs, lack of concerns by designers for buildability, among others. Critical solutions include early supply chain involvement in design process, choosing materials for their durability, early communication of design changes to all parties, longer project programmes and better lead times, among others.Practical implicationsIn all, the target of halving construction waste to landfill based on the 2008 benchmark is achievable but would require construction companies to take it upon themselves to implement the proposed solutions suggested by this study.Originality/valueThe value of this research is to provide UK construction companies with solutions to reduce waste and aid the reaching of the landfill target, as landfill is decreasing as a solution to waste. In addition the cost savings on reducing waste could be crucial for companies in this current economic climate.

Purpose Road construction projects are one of the strategic industries in each country and their construction and development requires spending huge funds. Regarding the increased demand and resource constraints; a technique which reduces costs by maintaining and improving the functioning is of great importance for the authorities of each country. Value engineering is a comprehensive and coherent means based on innovation and team work which, in addition to maintaining the quality and improving the project function, reduces its cost and is not limited to the design and construction phase; however, it includes exploitation and maintenance as well. This study aims to present a practical model for the implementation and application of value engineering process in a construction project located in a special region (in terms of tourism, positioning in an economic growth path, and the East-West strategic axis of the region). In this regard, after reviewing the advisor's design, considering the interests of the project stakeholders, reviewing design criteria and assessment methods and with the use of value engineering techniques, a new option was presented which led to a significant reduction in costs and time and an increase of quality, safety, and environmental factors. Finally, including initial costs, repair, maintenance, income and expenses, the relative value index of this option, compared to the advisor's option, increased from 0.9 to 3.5. Based on the increased need for development of roads in the country, exploiting this model in similar projects can significantly improve the project value and the effectiveness of investments. Design/methodology/approach This research project was selected with regard to the extremely high credit of the project and its potential in terms of Value Engineering implementation. In this study, technical and financial information were first collected after forming a value engineering team including a value engineering expert who was responsible for coordinating the work, some representatives of the employer, designer, executor, and budget estimator. In functional analysis phase with the use of FAST graph, advantageous, costly, and risky functions were identified. In the creativity phase, ideas related to selected functions were created and investigated and developed in the evaluation phase. Finally, calculating the value index, two variants with higher value index than the baseline plan, were proposed and implemented. Findings Since the determining criteria of designing and implementation of road construction projects including increased safety, reduced travel time, user satisfaction, ease of implementation, cost of construction and maintenance and so on are almost similar in most projects, using this study results and implementing its practical framework in other construction projects can be beneficial. These parameters lead to an increase in quality, value, and safety of the project. With regard to done steps and resulted incomes, this essay can be known as a practical and theoretical model to promote the value of crucial projects especially in developing countries. Research limitations/implications Sanandaj-Hamedan road with the length 176km connects central provinces of Iran. This study is regarding the first part of this route. Based on the specific topography of the region and the existing road limitations, selecting a good variance with all the features of an ideal road from geometric, economic, and safety aspects is a difficult task. Originality/value Employers and project sponsors are always looking for products with greater value and lower cost; therefore, present a practical model for the implementation and application of value engineering process in a construction project and providing a similar work experience can encourage the use of value engineering techniques and significantly improve the project value and the effectiveness of investments.

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.

Purpose The propose of this study is to focus on the mediating role of compliance with procurement regulatory frameworks in implementing public road construction projects. Design/methodology/approach A cross-sectional research design was adopted. Structured questionnaires were developed in a three-step process including generating items, purifying measurement items and validating measurement items. Variables were anchored on a five-point Likert scale because it is an efficient unidimensional scale that ensures all items measure the same thing and widely applicable in construction research. Findings The findings show that compliance with a public procurement regulatory framework significantly mediates the relationship between familiarity with a public procurement regulatory framework, monitoring activities, sanction on staff and contractors’ resistance to non-compliance and public road construction project success. However, compliance with a public procurement regulatory framework does not mediate the relationship between the professionalism of staff and perceived inefficiency with public road construction projects’ success. Research limitations/implications Limited mediation studies and examples in the public road construction subsector affected this study to comprehensively investigate and compare study findings. Furthermore, the study adopted a cross-sectional research design that limits responses to one point in time. Finally, the study missed out other participants in different organizations and departments that could have had relevant information. Social implications The study contributes to public procurement and construction management research fields by uncovering this strong mediating role of compliance with a public procurement regulatory framework that collectively would help the government to implement public road construction projects successfully. Because no single factor can reliably attain objectives, blending these factors through a hybrid governance system would enable the government to achieve value for money, increase the quality and quantity of paved roads and save funds that can be channeled to other priority sectors for economic development. Originality/value Despite scholarly efforts to establish project success factors, studies have been limited to factors directly impacting the project success without considering a mediating effect among the factors that affect the success of these projects.

Purpose Green building is a promising approach to improve resource efficiency and achieving sustainable development. The success of green construction projects is closely associated with the performance of project managers (PMs), while job satisfaction plays a major role in the performance of PMs. However, the emphasis placed on the job satisfaction of PMs in green construction projects remains minimal. The purpose of this paper is to identify the relationships between the job satisfaction of PMs and its key influencing factors in green construction projects, and to propose feasible strategies to improve the job satisfaction of PMs. Design/methodology/approach A questionnaire survey is conducted, data collected from 105 construction PMs are analysed using structural equation modelling. Interviews with five industry experts are further conducted to substantiate the results. Findings The results identified four major components of job satisfaction, namely, “job content”, “resource adequacy”, “work context” and “the personality and competence of jobholders”. The analysis also found that “technical requirement” and “split incentive” condition of green construction projects, “the expertise and awareness of PMs” and “demand and support from stakeholders” has significant impacts on PMs’ job satisfaction. Furthermore, this study developed eight strategies to improve PMs’ job satisfaction, including “increase recognition opportunities for PMs”, “government incentives and financial support” and “introductory and training courses on green construction legislation and processes”. Originality/value The findings assist construction companies in formulating measures to improve the job satisfaction and performance of PMs in green construction projects.

PurposeProject schedules have a vital role in the effective management of time, cost, scope and resources in construction projects, and creating schedules requires schedulers with construction knowledge and experience. The increase in the complexity of building projects and the emergence of building information modeling (BIM) in the architecture, engineering and construction industry have encouraged researchers to explore BIM capabilities for automated schedule generation. The scope and capabilities of the developed systems, however, are limited and the link between design and scheduling is still underdeveloped. This paper aims to investigate methods to develop a BIM-based framework to automatically generate schedules for concrete-framed buildings.Design/methodology/approachThis system first extracts the required data from the building information model, including elements’ dimensions, quantities, spatial information, materials and other related attributes. It then applies construction rules, prior knowledge and production rate data to create project work-packages, calculate their durations and determine their relationships. Finally, it organizes these results into a schedule using project management software.FindingsThis system provides an automated and easy-to-use approach to generate schedules for concrete-framed buildings that are modeled in a BIM platform. It provides two schedules for each project, both a sequential and an overlapped solution, which the schedulers can modify into a practical schedule based on conditions and available resources.Originality/valueThis research project presents an innovative approach to use BIM-based attributes of structural elements to develop list of work-packages and estimate their durations, and then it uses a combination of rule-based and case-based reasoning to generate the schedules.
