Abstract
Purpose
The growth of the Chinese economy has resulted in a significant increase in construction and demolition waste (CDW), and regional differences in CDW generation are gradually increasing. The purpose of this study is to investigate the regional differences in CDW generation and the driving factors that influence CDW generation in different areas of China. To provide a systematic advisement for local governments to select the appropriate policy, reduce CDW generation.
Design/methodology/approach
The generation of CDW was calculated by region, based on the area estimation method, from 2005 to 2018. The relationship between CDW generation and economic development, and the driving factors of CDW generation in different regions of China, was investigated using the environmental Kuznets curve (EKC) model and the STIRPAT theoretical model.
Findings
CDW generation of China increased at the average annual growth rate of 10.86% from 2005 to 2018. The main areas of CDW generation were concentrated in the eastern and central regions, while the proportion of CDW generation in the northeast region decreased gradually, and the changes varied significantly across different regions. The EKC between CDW generation and economic development was established for the whole country, North China, Northeast China, East China, Central South China, Southwest China and Northwest China. Three main factors based on the STIRPAT theoretical model were identified and explained into a framework to reduce CDW generation. The results provided a useful theoretical basis and data support guide for devising effective policies and regulations for the Chinese context.
Practical implications
The findings from this study can ultimately support policymakers and waste managers in formulating effective policies for waste management strategies and CDW-specific legislation. Additionally, it can help the coordinated reduction of CDW generation across regions in China and can support construction enterprises (in their development strategies), similar developing economies and foreign firms planning to operate in China.
Originality/value
This study contributes to the field through the STIRPAT model on driving factors of CDW generation in the Chinese context, in different regions.

Abstract
The construction industry plays a significant role to the economy of Hong Kong not only in terms of output but also the employment. The sector, however, has been severely hit by the economic downturn in recent years resulting in serious unemployment. Employment planning becomes one of the critical aspects for the recovery of the economy. The main objective of this paper is to establish a labour demand model for the Hong Kong construction industry. The unique characteristics and the current conditions of the construction labour market are reviewed. Regression analysis based on 123 construction projects was used to compute the relationship between expenditure and site workers employed. The best predictor of average labour demand of construction projects in Hong Kong is found to be DL = 463 C 0.934, where DL is the actual labour demand in man‐days, C is the final cost of contract in millions. The labour demand‐cost relationship can be applied as a manpower forecasting model to estimate the total labour required for a given type of project. The developed model enables a more reliable and accurate planning of manpower requirements in the construction industry.

Abstract
Purpose
The purposes of this paper are to identify the most significant job-related stressors that influence construction project professionals’ safety, identify the form of stresses and job burnout experienced by construction professionals and investigate the impact of stress and job burnout on safety performance from the perception of construction project professionals in the Gaza Strip construction industry. Construction is characterized as a stressful industry, which influences the safety performance of construction personnel, especially when the stress transfers into burnout.
Design/methodology/approach
The views of a variety of construction professionals operating in Gaza Strip were sought using a questionnaire survey. Project managers, project coordinators and site engineers were targeted. Of the 45 questionnaires distributed, 33 were returned. Data were analyzed using the relative importance index (RII), Pearson correlation and regression analysis that used one-way ANOVA test.
Findings
Findings revealed that an organizational stressor is the major contributor to physical stress, behavioral stress and job burnout. In addition, the findings showed that construction professionals suffered from emotional stress and invisible burnout. Of significance, the findings revealed that job stresses and job burnout did not affect safety performance in the Gaza Strip construction industry because the first priority for most construction professionals was to maintain permanent employment and, therefore, stresses were often hidden.
Research limitations/implications
This study is limited by its small sample size. However, the findings represent novel results, which can be taken into consideration by construction organizations.
Practical implications
The findings may help construction organizations in the Gaza Strip to understand job stressors’ factors, which affect construction project professionals to help minimize or eliminate their impact on safety performance and, hence, improve productivity in construction projects. Furthermore, the study promotes personnel health and safety and enhancement of the quality of work and construction workers’ personal life. The recommendation of this study may also apply to other developing countries.
Originality/value
The study contributes to the overall body of knowledge relevant to job stress and burnout in the construction industry of developing countries. It draws attention to the interrelationship between stressors, stresses, burnout and safety performance, and it illustrates a new form of burnout that is invisible burnout.

Abstract
Purpose
Knowledge sharing (KS) of employees has numerous benefits for organizations. Therefore, the aim of this study is to provide a model for KS in research centers (RCs) that can facilitate the employee's knowledge sharing behavior (KSB).
Design/methodology/approach
Based on the extensive literature review, a valid instrument was adopted to collect the required data set on KS, KSB and intention to KS, and finally 317 complete questionnaires were collected from Iranian research centers. The structural equation modeling (SEM) was used to assess the measurement model and to test the research hypotheses.
Findings
The findings show that intrinsic and extrinsic motivational factors and intention to methods of KS play an important role in KSB. In other words, simultaneous supply of motivational factors and KS methods interesting for employees lead to their KSB. The SEM confirmed the research model and showed a good fit of it.
Practical implications
The implication emanating from this study is that the employees' KSB in RCs as a significant part depends on simultaneous supplying of motivational factors (especially intrinsic motivational factors) and methods of KS that are interesting for employees.
Originality/value
What distinguishes this study from other studies in KS domain could be implied in two subjects. First, the presented model is simple and prepared of the introduced factors, which will lead to KSB. Second, this study was conducted in diverse research fields such as electrical and electronics, telecommunications, materials, chemistry, biotechnology, information technology, management and industrial engineering, computer network security, mechanical and manufacturing. The research model was derived from the collected data of these areas that is unique in this domain.

Abstract
Purpose
A mega‐event flagship (MEF) refers to a popular instrument developed for staging a mega‐event and catalyzing area‐based urban regeneration. Despite its lasting appeal and controversial nature, insufficient research on its critical early stage has been done to provide useful analysis. When the clients lack appropriate capabilities to confront sustainability challenges, MEFs may end up functioning poorly in the post‐event era and even hindering the progress of intended renewals. The purpose of this study is to enhance MEF clients’ capabilities in meeting sustainability challenges at the early stage and ultimately producing responsible MEFs of enduring worth.
Design/methodology/approach
The multiple‐case study method was adopted due to its widely recognized reliance on multiple sources to facilitate in‐depth analyses. Data were collected through archival records, documentation, direct observation and participant observation.
Findings
By proposing a comprehensive development framework based on the findings of multiple‐case studies, this paper corrects a misunderstanding of such a development being an end in itself, and contributes new insights into the definitional early stage of MEFs.
Social implications
The fact that MEFs are a global phenomenon as well as a local undertaking leads to a need to develop a database of useful lessons and critical decisions from previous MEFs, to establish a best practice targets system in future research.
Originality/value
As an initial attempt, this paper lays the groundwork for research on MEFs by investigating how mega‐event hosts have prepared in meeting its sustainability challenges.

Abstract
Purpose
Over decades, mega‐events have enjoyed increasing global popularity as catalysts of significant urban renewal both on and beyond the event grounds. Nevertheless, although some mega‐events are exemplary in their transformation of some places, post‐event failure of others highlight a lack of long‐range planning. Yet, such a paradoxical relationship between spectacularity and sustainability has, so far, received little in‐depth analysis. Building upon the Yin‐Yang theory, the purpose of this paper is to identify the Triple‐C gap and argues that planning for mega‐event led renewals (MELRs) is an issue of dualism rather than dichotomy.
Design/methodology/approach
This paper adopts the multiple‐case study approach. Two methodological steps are taken to seek a greater understanding of the issue at global and local scales. One is a review of eight mega‐event cases in the West to identify post‐event sustainability challenges. The other explores these challenges through an examination of the Expo 2010 development as a chapter of the Huangpu Riverfronts Renewal in Shanghai China.
Findings
The eight historical cases and Expo 2010 unanimously challenge the dichotomy between event staging and post‐event sustainability. It is therefore high time for future client organizations to rethink how to find a convergence.
Practical implications
With lessons drawn, the article concludes that planning an MELR should be pre‐post oriented and serve as a catalyst for broader‐scale improvements.
Originality/value
This pioneering study constitutes a much‐needed reference for future mega‐event hosts to rethink their commitment to MELDs, which will hopefully spark more interdisciplinary interest.

Abstract
Purpose
The construction industry has always been regarded as a stressful and task-driven industry with high levels of work pressure. When the stressful situations are prolonged, job burnout becomes unavoidable for construction professionals. The purpose of the present paper is to investigate the critical predictors of burnout among civil engineers at construction sites in Turkey and identify the impact of those determined burnout predictors on various burnout dimensions.
Design/methodology/approach
The possible causes of burnout for civil engineers at construction sites were determined using an extensive literature review and were further studied using a questionnaire. The obtained data were analysed statistically using SPSS 22 and LISREL 8.7 software. Correlation analysis, exploratory and confirmatory analysis, and structural equation modelling were performed on this collected data, and a structural model was developed.
Findings
Three critical factors affecting burnout levels of civil engineers in construction sites were determined; among them “organisational injustice” and “competitive pricing and lack of contract management” were identified as the critical predictors of burnout in the emotional-exhaustion and cynicism dimensions. Based on these predictors, potential solutions and recommendations are proposed that are anticipated to decrease the burnout among civil engineers at construction sites.
Originality/value
Although there are several works of research regarding the burnout among construction professionals, there is limited research that has provided insight into the specific factors causing burnout among civil engineers. This research presents a structural model of the predictors obtained by a confirmatory factor analysis for decreasing the burnout level of civil engineers at construction sites. The current study represents the first comprehensive quantitative determination of the factors and predictors of burnout among civil engineers at construction sites in Turkey.

Abstract
Purpose
This paper aims to analyse the factors influencing refurbishment site managers’ waste management efforts.
Design/methodology/approach
Twenty-seven semi-structured interviews were held with managers from two large contractors involved in housing and office refurbishment projects in Sweden. Also, a web and postal questionnaire survey was sent to 232 refurbishment site managers and received a 34 per cent response rate.
Findings
Site managers devise waste management strategies based on environmental inventories and project size. In smaller projects, waste contractors are employed only for physical activities rather than providing advice. Site managers’ waste management efforts are influenced by project-related factors, organizational and personal factors, technical factors, industry culture and legislation. The level of contract detail, specific client demands related to waste management and project size are important factors.
Practical implications
Policies and guidelines for projects of different sizes should be developed at least for large contractors; scale influences site managers’ waste strategies. Waste management efforts in refurbishment projects can be improved by addressing simple technical problems including providing clear labelling of containers and ensuring shelter from rain and snow.
Originality/value
This is a pioneer survey of refurbishment site manager opinions and practices. Inefficient waste management in building refurbishment projects can be costly and harmful to the environment. There are many opportunities to improve waste management efforts.

Abstract
Purpose
This paper aims to seek a greater understanding of the conceptualization of mega-event flagship (MEF) development as a point of departure to forge the much-needed organizational capacities in these regions. An MEF constitutes a temporarily themed venue for a mega-event and a transforming force on corresponding urban renewal. The unfailing demand for MEFs from emerging hosts after historical failures in the West draws attention to a glaring weakness of extant literature in wanting of evidence-based case studies.
Design/methodology/approach
Due to the explorative nature of research and the context-dependent complexities, the case study method is used for studying the case of Theme Pavilion – one of the four key flagships led by Expo 2010 to catalyze an ambitious urban renewal in Shanghai, China. The focus is on its conceptualization process (2004-2007) where different copying strategies were tested and consolidated to facilitate the post-event transformation. Data were collected mainly through participant observation in that duration.
Findings
For future Expo hosts, exhibition center developers and the event industry, the study concludes with eight constructive lessons, namely, clustering strategy, different integration, pre-post orientation, diversification for adaptation, development by stage, flexible mindset, the end crowns the work and building local capacity.
Research limitations/implications
Given the qualitative nature of the study, some results may not be fully generalizable. While showing the possibility of sustaining MEF development given the right coping strategy, it also reveals implementation difficulties and emphasizes the importance of continued case studies.
Originality/value
The study will contribute fresh insights into forging better strategies to cope with transformation difficulties of MEF development and building greater capacity to accomplish affiliated renewals and other significantly comparable urban projects in emerging economies.
