Purpose The large number of stakeholders in a project is a source of complexity because their inter-relationships can lead to complex interactions, an inadequate understanding of the other stakeholders and conflicting stakeholder interests. Although several studies have investigated the role and effects of engaging stakeholders in improving project success, studies examining the relationships between stakeholder engagement (SE) and quantitative and qualitative project performance (PP) in complex projects (CPs) have been limited. This study empirically examined the relationships between SE and project performance within complex and non-CP contexts. Design/methodology/approach The study used an extensive literature review to develop the conceptual model. The study identified 22 factors of measuring SE and project performance’s association within the context of CPs. The literature review followed by a questionnaire survey to collect data from quantifying the relationships. One hundred forty-four responses were received from project managers in different locations. The response data were subjected to structural equation modelling analysis. Confirmatory factor analysis was applied to evaluate the measurements model. Findings The current study generated several key findings. In the context of CPs, SE was found to negatively affect quantitative PP but to positively and significantly affect qualitative PP. In non-CPs, SE also positively affects qualitative PP. Further, in the context of CPs, SE negatively affects schedule performance, whereas no significant relationship was found between the two variables in non-CPs. In terms of cost performance, no significant relationship was observed between SE and cost performance for either group. Originality/value This research provides insight into differences in the relationship(s) between SE and PP in non-complex and CPs. The research also makes recommendations for project team members.

Most accidents in the aviation, maritime, and construction industries are caused by human error, which can be traced back to impaired mental performance and attention failure. In 1596, Du Laurens, a French anatomist and medical scientist, said that the eyes are the windows of the mind. Eye tracking research dates back almost 150 years and it has been widely used in different fields for several purposes. Overall, eye tracking technologies provide the means to capture in real time a variety of eye movements that reflect different human cognitive, emotional, and physiological states, which can be used to gain a wider understanding of the human mind in different scenarios. This systematic literature review explored the different applications of eye tracking research in three high-risk industries, namely aviation, maritime, and construction. The results of this research uncovered the demographic distribution and applications of eye tracking research, as well as the different technologies that have been integrated to study the visual, cognitive, and attentional aspects of human mental performance. Moreover, different research gaps and potential future research directions were highlighted in relation to the usage of additional technologies to support, validate, and enhance eye tracking research to better understand human mental performance.

Work in the oil and gas industry presents dangers and challenges because it is usually undertaken in remote locations and difficult geographical environments. Site and field remoteness could be significant for oil and gas workers, in terms of their mental health and fatigue levels. The purpose of this study was to identify the predictors of mental health and fatigue levels among oil and gas workers in isolated areas by measuring their levels of anxiety, depression, physical fatigue and mental fatigue. A cross-sectional study with data were collected during a 3-month period (from October 2018 to December 2018). Regression analyses, carried out on 387 responses, were used to identify predictors of mental health and fatigue levels. Results indicate that extended separation from family, friends and home country and marital status were major predictors of workers’ mental health and fatigue levels. Given this finding, companies in this sector need to focus on enhancing workers’ mental health and alleviating fatigue. Encouraging social capital between workers and providing the option of digital, social contact with their families can ensure that workers do not feel lonely or socially isolated. It is also recommended that companies facilitate a worker’s return home in the event of an emergency.

Resilient safety culture (RSC) is a socio-technical safety system that is made up of the employee’s capabilities as well the protocols and systems in an organization to deal with hazards. Oil and gas industry sites in Kuwait were chosen for this study. Both urban and rural sites were chosen to gauge the level of resilience in their respective safety cultures. Employees in remote sites experience high stress which may lead them to develop mental health disorders over time. High stress can also be caused due to loneliness of being aloof from the social circle and from an urban surroundings. Expatriates or employees in remote work sites experience greater stress at work due to these factors as compared to urban settings. Stress and mental illness have been identified to affect safety negatively. This, in turn, impacts on safety culture which is the focus of this paper. This study ranks constructs and indicators based on data analysis to show which constructs play important part in this case study.

The relatively high rate of injuries in construction is not surprising, as site work by its very nature ranks highly on fundamental risk factors. Working at heights often magnifies these risk factors. The literature reveals that falls from heights accounts for a large percentage of injuries in construction worldwide. Thailand is no exception, where fall accidents constitute the majority of high-rise construction accidents despite preventive measures being implemented. This paper examines how the use of a simple Ambient Intelligence (AmI) system—a device comprising a microcontroller, microwave sensors, Light Emitting Diode (LED) and audio alarm—could help to affect safety behavioural change of on-site construction workers in order to decrease the potential for fall accidents. An experiment was conducted at a high-rise building construction site in Bangkok, Thailand to examine the effectiveness of the AmI in helping workers mitigate the risk of falling from heights. The analysis of the data collected over two work weeks from the pre- and post-AmI application using X-bar charts and one-way analysis of variance (ANOVA) revealed a significant reduction of about 78% in the number of workers passing through the fall hazard zones. The finding established the potential of a simple AmI for reducing the risk of fall accidents.

For many countries, the oil and gas industry is regarded as one of the most lucrative and key sources of energy. Tasks in this sector can be classified under five main stages – exploration, oil extraction, refining, transporting and marketing of oil and its byproducts. Such tasks pose substantial risks to the environment, personnel and community at large. When accidents occur in the industry, the likelihood of human fatality is very high. Organisations where safety is highly critical (i.e. high exposure to risk and likelihood of an accident) poses particular challenges for leaders. Thus, such organisations call for specific leadership/leadership behaviours, which may differ from those most effective in less safety-critical organisations. Therefore, this paper examines some key accidents in the oil and gas industry that had huge influence on the development of safety legislations. The paper is centred on the literature review and the selected accidents; based on the following themes – leadership, safety culture, safety outcomes, and safety climate. Discussions on the study carried out was presented, followed by a framework for safety leadership. Finally, this paper concludes that safety-critical organisations require leadership that influences followers to behave safely, acts as a role model and exhibits profound concern for safety.

Hospitals are a critical element of the healthcare system and their continuous function is highly important to the wellbeing of communities. In accordance with the criticality of their functional performance during disruptive events, several modelling and analysis approaches have been developed to investigate the extent of various aspects of hospitals’ vulnerability and resilience. However, these approaches fall short in addressing either the degree of absorption, adaptation and, in some cases, degradation of the hospital as a system before its fundamental breakdown or fail to differentiate their performance in normal conditions versus surge circumstances and protocols. In this paper, these issues were addressed via deployment of the Functional Resonance Analysis Method (FRAM) and a macro analysis of the interactions among hospital system functions under surge conditions. The use of FRAM as the modelling technique helps to address the extent of system adaptability to changes and explore the hidden impact of different functions on overall system performance. The modelling involved identification of surge functions and fulfilment of conditions for the functions generating the outcomes. The study identifies the limitations existing in hospital surge procedures and highlights the difference between work-as-imagined and work-as-done regarding hospital surge procedures.

Complexity is a critical factor in managing a project, as it presents an additional difficulty in achieving the project’s objectives. As complexity makes a project more challenging to understand and keep under control, agile methodologies have been developed to enable increased flexibility and responsiveness to changing conditions. Therefore, it is essential to empirically examine the moderating effect of project complexity on the relationship between agile response-to-change (AR) and project performance. To address this objective, a questionnaire was used to measure project complexity, project performance and AR. Structural equation modelling was used to explore the relationship between these variables. The results suggested that internal AR has a positive effect on budget performance. Project complexity appears to lower the relationship between internal AR and schedule performance. As one would expect, the higher the level of project complexity, the more likely the project is to experience delays.

In order to put a proactive approach in place with regards to the prevention of workplace injuries, there is a lean towards the main determinants of safety; e.g. leadership. As a result of their vital role in organisations, leaders are seen as prime players in the creation of safe work environments. However, leadership is a complex, multi-phased concept which advocates that various leadership styles affect the outcome of safety in diverse ways. Therefore, this paper highlighted that complex systems predominantly focus on the relationship amongst teams, behavioural patterns and the interdependencies within an evolving system. Thus, applying the same concept to safety and leadership provided direction in practice and presented an unorthodox leadership construct that would enable managers to imbibe leadership apt for the twenty-first century. The aim of this paper was to develop a framework for safety leadership functions using complexity science. This study was centred on literature review based on the following themes—leadership style, complexity leadership theory and safety leadership. Discussions on the study carried out was presented, followed by a framework for safety leadership. This paper concluded that complexity science supports the flexibility, innovative and dynamism of leadership; not as a set of capabilities or standards innate in any one person.

This research aims to develop a cloud-based safety information and communication system in infrastructure construction projects. To achieve this aim, the current paper-based construction safety management was reviewed. Following this, a cloud-based safety information and communication system, which incorporates geographic information system (GIS) and Global Position System (GPS), has been designed and developed. Google Drive was chosen as the system database and hosting web server, where the Google Docs, Sheets and Forms are tailored to accurately capture on-site safety data with mobile devices. The captured data with its actual construction activity location is automatically synchronized in Google Fusion Tables and the processed safety information is visualized simultaneously on Google Maps together with the project’s general information. Both data capturing and visualization processes are managed in a single web interface, bringing easy-to-use benefits to end users. The system was trial tested with a real case project, which confirmed its usability and benefits. The system developed in this research has potential applications in managing safety in infrastructure construction projects.

This research aims to develop a cloud-based safety information and communication system for improving safety performance of infrastructure projects. To achieve this aim, firstly, current traditional paper-based construction safety management system and practice are described, together with a review of the potential application of cloud-based information technology in safety management. Secondly, a cloud-based safety information and communication system (named as MapSafe) was designed and developed by using a free-to-use online web server. The MapSafe system functions include Pre-Starting Safety Meeting Recording, Permit to Penetrate Request and Approval, Job Safety Analysis, and Safety Incident Reporting. The system was tested by using a road construction project and the results show it is a robust system that can be applied to improve safety. The key contribution of this research includes mapping the processes of safety information collection, analysis and approval, and pointing out the way for future application of cloud computing in construction safety management.No Full Tex

Purpose The Gaza Strip in Palestine is suffering from a shortage of water and energy. To manage the current situation and address future issues, practical approaches need to be adopted to enhance water and energy efficiency. The purpose of this paper is to elicit professionals’ perceptions of the drivers affecting water and related energy consumption in residential buildings in the Gaza Strip. Design/methodology/approach In total, 19 drivers were identified from previous research and modified according to the results of a pilot study. These drivers were ranked under a Relative Importance Index (RII). A questionnaire survey was then administered and non-random purposive sampling used. The population of this study comprised stakeholders, including the United Nation Refugee Work Agency, Gaza Strip Governorates Municipalities, and the Coastal Municipalities Water Utility. Findings The results of all drivers (i.e. RII=71.43 per cent, mean=3.57) indicated that the respondents agreed about which drivers were affecting water and energy consumption. The sign Test-value was a positive 4.55 and the p-value was 0.000 (i.e. smaller than the level of significance a=0.050). The means of these drivers differed significantly and were greater than the hypothesised value of 3. Accordingly, it was concluded that the drivers investigated significantly affected household residents’ consumption of water and energy in residential buildings. The study revealed that climate changes, knowledge of how to conserve water and energy and household size were the most important drivers affecting household residents’ consumption of water and related energy in residential buildings. Practical implications The study will assist the parties concerned about water and energy use to be aware and understand the drivers affecting water and related energy the consumption in order to provide household residents with the necessary knowledge to ensure conservation and sustainability. Although this study related to a narrow geographical area in Palestine, the findings could be useful to similar locations in the Middle East and Africa. Originality/value This research demonstrates the drivers affecting water and related energy the consumption in residential buildings in the Gaza Strip which is considered the first study in Palestine and in the region. The study provides a useful platform for the development of appropriate water and energy strategies in Palestine and other similar geographical locations in the Middle East.

Purpose The purpose of this paper is to provide the empirical evidence supporting the existence of a multi-level hierarchical TQM model showing the structural inter-relationships among a total of 16 TQM variables (i.e. drivers, enablers and outcomes). Design/methodology/approach The set of identified TQM variables is the product of an in-depth review of the literature, and a robust reiterative process of verification and validation. Inter-relationships among the TQM variables were subjected to the scrutiny of a panel of experts, and were used as a basis for developing a web-based survey to explore the existence as well as strength of the structural relationship between each and every pair of the identified variables using interpretive structural modelling and MICMAC (Impact Matrix Cross-Reference Multiplication Applied to a Classification). Findings TQM variables were classified and clustered based on their influence and dependence on each other. Variables such as commitment by top management and customer satisfaction appear to have a strong chance to affect change, whereas variables such suppliers and competitors are very dependent on, and sensitive to, the evolution of the influent variables. Originality/value The paper demonstrates a multi-level TQM model encompassing all identified TQM drivers, enablers, and outcomes. The paper not only addresses a gap in the relevant literature (reduces the evidence scarcity about the hierarchical nature of TQM variables), but also gives insights into the variables with most driving power needing greater management attention.

This research aims at developing a hybrid model for non-homogeneous group decision making in the supplier selection process to select a supplier that best satisfies the purchaser. The model uses the analytical hierarchy process (AHP) in determining the influence weightings of company function department (CFD), then the house of quality (HOQ), as an essential part of the quality function deployment (QFD) concept, is applied to transfer company function department (CFD) requirements to suppliers' attributes. Finally, the Linguistic Ordered Weighted Averaging (LOWA) operator is applied for aggregating the linguistic opinions of the non-homogeneous group. The importance weightings of CFD requirements, criteria and final suppliers score are calculated by applying a mathematical algorithm.

Benefits to the construction industry through the use of off-site manufactured (OSM) buildings are well documented. However, and like most innovations, the uptake of OSM has been rather slow. While relevant potential improvements and barriers are widely discussed in the literature, there is a gap in understanding how key project stakeholders (i.e. clients and manufacturers) perceive the value created by adopting OSM into their projects. This paper attempts to fill that gap by developing a value-based model, with its constituents firmly rooted in the seminal literature. The model depicts factors critical to value-creation from both product and process perspectives, allowing for causal relationships among all the inputs and outputs. A systems approach was adopted where causal relationships involving key identified stakeholders are modelled. Industry consultations have led to the identification of the levels of influence and dependency that each factor has on the value creation process.

Many of the shortcomings associated with dated design and construction methods as well as project fast-tracking can be addressed by exploring the concept of concurrency facilitated by Building Information Modelling (BIM). From a BIM perspective, concurrency facilitates the involvement of stakeholders from very early on during the lifecycle of a project. Leveraging the 5 W/H (Who, What, When/Where, Why and How) method of exploratory research, this paper explores how BIM and Concurrent Engineering (CE) at Terminal 3A of the Chongqing Jiangbei International Airport compares with a historical exemplar of BIM deployment in the AEC industry. Based on existing definitions of CE, we compare both projects to determine their conformance to three CE criteria: 1) compressed project duration, 2) enhanced product value, and 3) reduced project costs. We also review their use of collaborative tools and techniques. The paper shows how the success of BIM-based projects can be rationalised by CE.

Systems thinking is a philosophy currently prevalent within construction safety literature that is applied to understand and improve safety in sociotechnical systems. Among systems, the site-project organizational system is of particular interest to this paper. Using focus group and survey feedback research to learn about how safety incidents effect levels of construction workers engagement this paper reveals how a safety incident provides an opportunity to create a potential quality (productivity) upgrade within an organization. The research approach involved a qualitative study involving 27 frontline supervisors and a follow-up survey completed by 207 frontline workers in the Australian Asphalt and Pavement Industry. The focus group interviews supported the articulation of the concepts of tacit safety, explicit safety, situational awareness, foresight ability, practical intelligence and crew synergy. Our findings indicate that having regular shift changes and other job site workers being fatigued are influential on perceptions of tacit safety. An individual's foresight ability was found to be the most potent predictor of worker perceptions of work engagement. The paper explains that relatively small improvements in worker perceptions of safety can bring about significant improvements in employee engagement and productivity.

Recent innovation diffusion in organisations literature suggests that innovation diffusion dimensions and characteristics are not independent of each other, rather organisational internal environment interacts with both an organisational external environment and an innovation’s characteristics. The purpose of this paper is to examine the validity of the framework consisting of organisational innovation dimensions and characteristics within Saudi Arabian organisations. We test this model with survey data from a large-scale survey of 223 Saudi public and private project-based organisations, these organisations had either adopted, or intended to adopt, the project management office (PMO). To obtain a broad representation of respondents, and to minimise bias, the survey did not target any specific industry. Statistical analysis, specifically exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to ascertain the factors underlying each construct. Structural equations modelling (SEM) was sequentially utilised to determine the factor structure of the model and to assess the relationships between model constructs. This paper took an initiative step towards a conceptual framework for organisational innovation diffusion, represented by the PMO.
