Purpose The present shift and change in the human lifestyle across the world are undeniable. Currently, individuals spend a substantial amount of time indoors due to the global COVID-19 pandemic that strikes the entire world. This change in human lifestyle has devastating effects on human health and productivity. As a result, the influence of indoor environmental quality (IEQ) on the health and productivity of building users becomes a critical field of research that requires immediate attention. As a result, the purpose of this study is to review the state-of-the-art literature by establishing a connection between the factors that influence health and productivity in any given indoor environment. Design/methodology/approach The methodology involves a thorough review of selected published journals from 1983 to 2021, and the result was analysed through content analysis. The search included journal articles, books and conference proceedings on the critical factors influencing IEQ and their impact on building occupants, which was sourced from different databases such as ScienceDirect, Taylor, GoogleScholar and Web of Science. Findings The findings from the 90 selected articles revealed four critical factors influencing the quality of the indoor environment and are categorised into; indoor air quality, indoor thermal comfort, visual comfort and acoustic comfort. The findings suggested that when developing a system for controlling the quality of the indoor environment, the indoor air quality, indoor thermal comfort, visual comfort and acoustic comfort should be taken into account. Originality/value The indoor environment deeply impacts the health of individuals in their living and work environments. Industry must have a moral responsibility to provide health facilities in which people and workers feel satisfies and give conditions for prosperity. Addressing these essential aspects will not only help the decision-making process of construction professionals but also encourages innovative construction techniques that will enhance the satisfaction, wellness and performance of building occupants.

Purpose Construction cost management is one of the important processes that should be achieved effectively and accurately for successful project delivery. Modern-day construction cost management demands a high level of spatial skills. Augmented reality (AR) can potentially increase the stakeholders’ spatial skills as a supportive technology to traditional cost management tools and techniques. AR is a breakthrough technology that could considerably ease execution in various industries, but AR applicability in cost management has not been studied extensively. Thus, this study aims to explore the use of AR in construction cost management tools and techniques. Design/methodology/approach Data were collected using a qualitative approach consisting of two rounds of the Delphi technique. A total of 22 experts in the construction and information technology fields were interviewed using a purposive sampling technique. The manual content analysis helped analyse data. Findings The study identified AR features with the potential to increase the usage of cost management tools and techniques. AR can enable spatial skills (abilities, thinking and tasks) in most cost management tools and techniques. However, technical, cultural and technical and cultural barriers obstruct the use of AR in the construction industry. Originality/value The usage of AR in construction cost management tools and techniques has not been examined in detail until now. Thus, the study was developed to meet the industry needs and fill the literature gap to investigate the potential use of AR in construction cost management tools and techniques.

Purpose The failure rate of international construction joint venture (ICJV) projects has been noted to be high in developing countries due to the complexity and risky nature of construction projects in the international market. The purpose of this study is to identify and evaluate the risks facing ICJV projects in Ghana. Design/methodology/approach A risk register was developed through a comprehensive literature review. The identified risks were then used in a questionnaire survey involving local and foreign partners in ICJV projects in Ghana. Findings From a total of 74 risks identified, categorized into country-level risks, market-level risks and project-level risks, the “top ten” risks found to be the most critical risks facing ICJV projects in Ghana include unstable currency exchange rates, inflation, design changes, high-interest rate, budget overrun, cash flow problems of the client, economy fluctuation, difficulty in obtaining approval of projects from host government authorities/bureaucracy, potential financial distress of JV partner and bribery and corruption. Originality/value This study provides a comprehensive list of risks ICJV partners are likely to encounter on their projects in developing countries. Furthermore, this study improves on one of the major limitations of previous ICJV studies by collecting data from both partners of the ICJV, appropriate for cross-cultural examination and comparison.

Purpose Buildability assessment is an important tool used in improving buildability of building designs. Its practice has positive impact on construction project such as cost-saving, material waste reduction, labour-saving technologies, increase in efficiency, saving wasteful efforts and quality improvement as well as cost-effective methods of site construction and future maintenance. However, there are several factors hindering building construction industry to implement buildability assessment. In addition, there are few studies that described the factors impeding the implementation of buildability assessment in construction industry. This study aims to determine the factors impeding buildability assessment implementation in the Nigerian building construction industry Design/methodology/approach Quantitative research method was adopted for the study. Questionnaires were administered to purposively selected group of architects, engineers, builders and quantity surveyors. A total of 368 questionnaires were distributed among the sampled participants, out of which a total of 219 representing 60% were sufficiently filled and returned. Data elicited were analysed using inferential and descriptive statistics. Findings The results revealed that “poor co-ordination amongst different design disciplines”, “lack of buildability assessment awareness”, “design review pattern where construction personnel (builders) are invited to assess the building production information”, “unwillingness to invest extra money and effort during the early stage of project” and “designers value aesthetics and functionalities more than buildability in their designs” are the topmost five factors impeding buildability assessment implementation in the Nigerian construction industry. Originality/value This study highlights factors impeding the implementation of buildability assessment in construction industry. An understanding of these factors can help stakeholders in the construction industry facilitate the development of strategies required to mitigate the factors impeding buildability assessment implementation in the sector.

Purpose The construction industry has been recording a high number of accidents without any sign of abating, the majority of which have been linked to poor health and safety practices. To reduce this menace, this study aims to evaluate the factors affecting health and safety practices on construction sites to improve health and safety practices. Design/methodology/approach First, this study reviewed previous studies to derive the factors affecting health and safety practices on construction sites, and based on the literature review, the 50 factors identified were used in developing the questionnaire that was administered to construction professionals. The returned questionnaire was then analysed using fuzzy synthetic evaluation (FSE). Findings According to the FSE results, inadequate safety planning has the highest critical value, followed by management failure, inadequate safety promotion, safety ignorance, poor supervision and enforcement, a casual attitude towards safety and insufficient experience. The analysis showed that the overall criticality of the factors to the Malaysian construction industry is high, suggesting that if addressed, the health and safety practices of the industry will be improved. Originality/value The study provides a holistic approach to the factors affecting health and safety practices in the construction industry using a method that has not been used by previous researchers. The findings will furnish decision makers in the construction industry with practical approaches to adapt and reinforce in the industry to improve health and safety practices.

Purpose The role of construction industry in harnessing human and material resources of a nation cannot be overemphasised; hence, the emergence of the requirement of leadership. This study aims to assess the usage of factors of transactional leadership style (TSLS) by the project managers (PMs) in the Nigeria construction industry. Design/methodology/approach A survey research design approach with questionnaire as an instrument of gathering data was adopted. Out of 1,233 questionnaires distributed, data from 975 received with acceptable feedback were analysed using both descriptive and inferential statistics. Findings This study revealed the following factors under active management by exception as the TSLS factors often employed by PMs in Nigeria. These factors are the three frequently used factors: they are: “always give clear and final instructions to be implemented in the project”; “always observed the progress of the project, assessed risk and took precaution to avoid mistakes in the project”; and “always closely monitor performance for errors needing correction”. This study concludes that it is imperative for PMs in the study area to adopt and incorporate these factors to ensure continuous successful delivery of construction projects. Practical implications Therefore, it is hoped that the findings of this research will help the construction industry managers to address the age-long but unrecognised leadership problem confronting the sector, thereby boosting project delivery. Originality/value The findings establish the appropriateness or otherwise of adoption of factors of transactional leadership, either in part or a whole.

Purpose Although the overall impacts of innovation and innovative practices have been emphasized in recent years, the effect on the growth of firms in Nigeria have not been proven. Therefore, this study aims to investigate the effect of innovative practices on the growth of quantity surveying firms (QSFs) in Nigeria. Design/methodology/approach The study adopted the quantitative correlational research design in which a well-structured questionnaire was used to collect data from QSFs in South-West, Nigeria. The data were analyzed using descriptive statistics and multiple regression analysis to investigate the effect of innovative practices on the growth of QSFs. Findings The study reveals that there is a significant increase in the growth indices used for assessing QSFs, while all the innovation variables were found to be reliable. Based on the result of multiple regression analysis, the relationships were identified as follows: quantity surveying (QS) software influenced the size growth of QSFs; QS software and services affected client growth and profit growth; and all innovation practices impacted asset growth of QSFs. Practical implications Although the use of software tools has been found to negatively affect the size of QSFs and other growth indices, there is need for them to embrace innovative software applications for more quality service delivery. In addition, QSFs should formulate strategic objectives that will guide them in taking informed decisions for diversification.

Therefore, this study aims to investigate the effect of innovative practices on the growth of quantity surveying firms (QSFs) in Nigeria.\u0000\u0000\u0000Design/methodology/approach\u0000The study adopted the quantitative correlational research design in which a well-structured questionnaire was used to collect data from QSFs in South-West, Nigeria. The data were analyzed using descriptive statistics and multiple regression analysis to investigate the effect of innovative practices on the growth of QSFs.\u0000\u0000\u0000Findings\u0000The study reveals that there is a significant increase in the growth indices used for assessing QSFs, while all the innovation variables were found to be reliable. Based on the result of multiple regression analysis, the relationships were identified as follows: quantity surveying (QS) software influenced the size growth of QSFs; QS software and services affected client growth and profit growth; and all innovation practices impacted asset growth of QSFs.\u0000\u0000\u0000Practical implications\u0000Although the use of software tools has been found to negatively affect the size of QSFs and other growth indices, there is need for them to embrace innovative software applications for more quality service delivery.

Purpose The purpose of this study is to present a system dynamic (SD)-based remanufacturing economic analysis model of used automobile engine under two recycling modes. The authors will compare the remanufacturing cost, sales profit and sales revenue from time and space dimensions incurred in different recycling modes in the long run. Design/methodology/approach The remanufacturing economic analysis model is based on SD methodology. The authors can simulate the relations of impact factors on automobile engine recycling and remanufacturing and further analyze and compare the cost, sales profit and sales revenue incurred in different recycling modes in the long term. Findings Sinotruk Steyr engine remanufacturing in Shandong province is taken as the research case subject. The revenue, cost and profit under the two recycling modes from 2015 to 2035 are analyzed and compared. The results show that different recycling modes have significant varying influence on the economy of engine remanufacturing. Originality/value This economic analysis model can provide a method reference to decide the recycling mode for auto components and other product remanufacturing. Moreover, this model can guide and support the sustainable development of remanufacturing industry.

Purpose Many parameters influence the success of sustainable projects (SPs) in the architecture–engineering–construction. One of these important parameters is the project delivery attributes (PDA), which are influenced by the project delivery system (PDS) while affecting the selection of it. This study aims to evaluate the significance of PDAs in influencing both the performance and success of SPs in Turkey, where the interest in SPs is high. Design/methodology/approach The impact of PDAs was determined by applying the two-round Delphi method with a semistructured interview involving the main stakeholders of a construction project, like owners, designers, contractors and consultants who played active roles in SPs, as well as academics to theoretically evaluate the issue. The significance of PDAs was assessed using the relative importance index, and the results were validated using the interrater agreement analysis. Findings The study identified key PDAs impacting SPs as owner character, commitment and motivation; simulation and energy modelling; and timing of stakeholders/early involvement. Originality/value The investigation of the significance of the PDAs is a lesser-studied context. Therefore, a research framework that enables an effective set of methods for solving the sectoral problems of PDAs that have impacts on SPs has been proposed. The framework is expected to open new opportunities for the generation and regulation of the PDSs for SPs. The findings will provide valuable insights to project stakeholders, particularly owners, local authorities and policymakers to assess which PDAs have a greater impact on sustainability performance when setting PDSs in SPs in other developing countries.
