    Exploratory factors influencing building development costs in New Zealand
    (MDPI AG, 29/06/2017) Zhao L; Mbachu JIC; Domingo N
    Identification of costs drivers and their influence levels on building development costs plays a key role in the development of construction models and improve the efficiency and effectiveness of any project. Forty-five indicators influencing building development costs in New Zealand were explored by literature review and pilot interviews. These indicators were grouped into seven categories. The determination and ranking of the significant cost drivers were carried out through questionnaire survey distributed to key professionals working in New Zealand construction industry. Structural equation modeling (SEM) was used in analysing the empirical data. Findings showed that the property market, construction industry characteristics, statutory and regulatory, and socio-economic factors were major drivers of the building development cost trends in New Zealand. It was recommended that the ever-increasing building development costs and housing unaffordability in New Zealand could be significantly mitigated by addressing the identified factors.

    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.
