Waste management and minimization are touted to be two of the key drivers for greening the construction industry and a pathway to a circular economy. This research aims to revisit the attitudes and perceptions of project stakeholders towards construction and demolition (C&D) waste in the Australian construction industry and ascertain if the current state of play in construction would facilitate the transition to a circular economy. Statistical analysis was performed on an online survey dataset collected from 104 professionals within the Australian construction supply chain. The results reveal that construction professionals' attitudes and perceptions to C&D waste could be classified into normative, regulatory and cultural cognitive drivers. Also, the perceived barriers and strategies of C&D waste management vary across design consultants and principal and sub-contractors. Overall, the evidence is suggestive that the Australian construction industry seems not fully ready for a circular economy. In terms of research implications, clearer guidelines and mandatory approaches to C&D waste management, involving a balance of incentivization and dis-incentivization actions, and close and stronger collaborations between the industry and government, are deemed necessary for better C&D waste management performance and the realization of a greener industry.

This study aims to examine construction firms' awareness and implementation of various aspects of corporate social responsibility (CSR) practices and ascertain whether the level of CSR awareness and implementation would vary across firms with different ownership and control. An online questionnaire survey was undertaken across extra-grade construction firms in China. The results show that respondents' CSR priorities are built around the aspects of quality, safety, and environment. They tend to adopt a more integrated approach to managing the interests of diverse stakeholders. It is notable that there are positive correlations between the firms' CSR awareness and implementation and that listed firms tend to exhibit a higher level of CSR awareness and implementation than their counterparts. In conclusion, the findings inform policymakers and practitioners of the status quo of CSR, thus enabling them to configure targeted strategies to improve the overall CSR awareness and implementation in China's construction industry.

An objective evaluation of users’ long-term satisfaction with the post-disaster permanent housing provided is important for judging the successes or failures of housing reconstruction programs. Focussing on four resettlement sites built via the REKOMPAK program after the 2010 Merapi eruption, this paper examines the users’ long-term satisfaction with the provided housing, and explores how their satisfaction level relates to their demographic characteristics and level of participation in the reconstruction processes. The results show that the households are in overall satisfied with the present housing. Their overall satisfaction level is statistically positively associated with household income, but not their level of participation and other demographic characteristics. These findings provide evidence on a satisfactory outcome in the long-term for the REKOMPAK, a community-based reconstruction program that was implemented in Indonesia since 2004, and a useful insight for local authorities, humanitarian and other agencies involved in post-disaster reconstruction program.

Individual contractors exhibit different bidding behaviors when confronted with a given set of project decision environment factors, i.e., heterogeneity in the population of contractors. In examining the tenability of the bidder homogeneity assumption, a linear mixed modeling approach is applied to two data sets obtained from Hong Kong and Singapore contractors via a bidding experiment. Two linear mixed models were developed by relating the contractors' mark-up decision to four project decision environment factors, namely, (1) market conditions; (2) number of bidders; (3) project type; and (4) project size. The results show that not only is there a significant heterogeneity between the Hong Kong and the Singapore contractors in terms of both their preferences (intercepts) and responses (slopes) to the project decision environment factors that affect their mark-up decision, but also that the individual Hong Kong and Singapore contractors have different degrees of sensitivity toward the project decision environment factors (which is reflected in the varying individual-specific intercepts and slopes). These individual-specific parameter estimates have implications for managerial action in formulating a firm's competitive strategies.

This research is based on the premise that there is heterogeneity in the population of contractors, i.e., that individual contractors exhibit different bidding behavior when confronted with a given set of bidding variables. Random-coefficients logistic model is used to explicitly measure the heterogeneity across contractors in terms of their (1) intrinsic bid/no-bid preferences and (2) responses to four bidding variables, i.e., number of bidders, market conditions, project type, and size. The binary bid/no-bid decisions were assumed to arise from a logistic model, but with the model parameters that varied between contractors. Data were gathered using a bidding experiment involving Hong Kong and Singapore contractors. The results show that there is significant heterogeneity across the contractors in which Hong Kong contractors can be clustered into four groups of identical (statistical) behavior in response to the four bidding variables, whereas in Singapore, there are only three groups as determined by the underlying heterogeneity distribution. This probabilistic classification of contractors has implications for contractors' competitive strategies by targeting different groups of competitors toward maximum competitiveness.
