    Towards Effective Implementation of Carbon Reduction Strategies in Construction Procurement: A Case Study of New Zealand
    (MDPI AG, 30/09/2022) He P; Bui TTP; Shahzad W; Wilkinson S; Domingo N
    In light of climate change, the construction industry plays a crucial part in alleviating carbon emissions and other environmental impacts. The focus on improving the public procurement process poses an important opportunity for the successful implementation of carbon reduction strategies in construction projects. There is a growing body of literature mapping green and sustainable procurement practices in construction. However, previous studies have not treated the implementation of procurement in a particular area, such as carbon reduction, in much detail. This study aims to investigate the implementation of construction procurement incorporating carbon reduction strategies, with a specific focus on the public sector in New Zealand. The research was conducted through 13 semi-structured interviews with construction procurement experts in New Zealand. The results shed light on the current implementation of carbon reduction strategies in construction procurement and its challenges, such as a lack of knowledge and ambiguous procurement guidelines and documents. It also emphasises the importance of (1) well-developed carbon reduction evaluation criteria, (2) specifying a budget for carbon-related initiatives, and (3) the prerequisite of a high level of innovation in the procurement document. The study adds to the rapidly expanding field of carbon reduction construction procurement by providing a deeper insight into the way carbon reduction strategies are effectively implemented in the procurement process.

    Risk identification, assessment, and allocation in PPP projects: A systematic review
    (MDPI AG, 27/07/2022) Rasheed N; Shahzad W; Khalfan M; Rotimi JOB
    Public private partnerships (PPPs) have gained widespread adoption as an innovative way of procuring public infrastructure projects over the last two decades. Risk identification, assessment, and allocation have received considerable attention from researchers due to the risk heavy nature of PPP projects. Adoption of PPPs has triggered a sudden increase in research interest in the area in recent years. This study attempts to provide an updated systematic review of literature related to risks in PPPs using a PRISMA flowchart. The results of the study offer some valuable insights into the future and current state of research. The study found that the focus of research on PPPs has shifted from an overall risk identification and assessment approach to individual risk analysis. Moreover, this research trend is on the rise in developing countries, and that quantitative methods for risk management in PPP research and qualitative methods in practice are preferred. In developed economies, due to negative public sentiments, transparency concerns, and arguments of value for money not being achieved, PPPs are becoming less popular. For these reasons a shift to availability-based payment mechanisms such as in Design-Build-Finance-Maintain (DBFM) from traditional revenue-based mechanisms as in Build-Operate-Transfer (BOT) has been observed. These shifts in research trends and practice offer researchers future opportunities to investigate these relatively newer approaches.
