    An optimisation process to motivate effective adoption of BIM for refurbishment of complex buildings in New Zealand
    (Higher Education Press Limited Company. Publishing services by Elsevier B.V. on behalf of KeAi Communications Co. Ltd., 2019-12) Okakpu A; GhaffarianHoseini A; Tookey J; Haar J; Ghaffarian Hoseini A
    Despite the multidisciplinary networks involved in refurbishment of complex building projects, the lack of BIM adoption signifies lack of real BIM benefits towards acceptance of BIM within Architecture, Engineering and Construction (AEC). To this end, this study empirically examines the potential real benefits between traditional network and BIM network for a real-time refurbishment case study project, through agent-based simulation modelling. A social network analysis theory is adapted to model the project interaction networks and a BIM prototype network. An assessment of the main stakeholders for BIM perception is carried out. We offered three prototype interaction networks for comparison of real BIM benefit. An agent-based Bayesian network model is used to simulate the propagation of design error within the project networks. The result of the analysis show that BIM project diffuses error efficiently, while stakeholders recovers faster and nearly at the same time than traditional network. The optimised network shows better performance to the traditional network, when there is early involvement of subcontractors. The main contribution of this study is providing a novel approach to compare real benefits for traditional method to BIM method for refurbishment project and to provide avenue for project stakeholders to optimise their interaction through adoption of BIM.

    Business environment, CRM, and sustainable performance of construction industry in New Zealand: A linear regression model
    (MDPI AG, 2021) Alqudah HE; Poshdar M; Oyewobi L; Rotimi JOB; Tookey J
    Increasing fragmentation of the construction industry makes it riskier and more competitive. Construction management researchers have become intrigued by the factors influencing performance differentials due to such fierce competition. This study examines the relationships between the business environment and customer relationship management and their effect on construction organisations sustainable performance. It develops a model to explain performance differential between construction organisations in New Zealand by using the linear regression technique. A questionnaire was administered to professionals within construction organisations. A total of 101 usable responses were analyzed for descriptive statistics and correlations. Following the balanced scorecard performance metric, the organisations’ sustainable performance was measured using customers, financials, internal processes, and growth and learning metrics. Results indicated that environmental dynamism had a significant regression with internal business processes and perspectives on learning and growth, with 0.259 and 0.607, respectively. CRM was significantly associated with financial (0.327), customer (0.373), and internal business process (0.451) perspectives. This study provides an integrative framework to construction enterprises, and determinants of organisational sustainable performance, which are substantial developments in the current literature on CRM practices. Given the significance of the construction sector to the global economy, ecology, and social well-being, its sustainable performance can lead to a sustainable future for communities.

    Evaluating defect reporting in new residential buildings in New Zealand
    (MDPI AG, Basel, Switzerland, 2015) Rotimi FE; Tookey J; Rotimi JO
    The need for defect reporting is becoming increasingly difficult to ignore at handover of new residential buildings. A general review in defect studies has consistently shown that newly built properties can be found to have a significant number of defects. Very often the responsibility for rectifying these common defects is borne by the new homeowner even though house developers are liable. In the current study, survey data is obtained from 216 recent home purchasers/owners across New Zealand urban cities. The intent of the investigation is to show that opportunities exist for defect reporting that will act as a mechanism to measure performance and thus improve the quality of finished construction products in New Zealand. The study found that a significant number (81%) of the participants were involved in the construction of their homes and could influence quality performance if they were proactive enough. The results show that (64.7%) did not engage the service of independent building inspectors for defect reporting on their new homes. Seventy-four percent now agree that independent building inspection was important in hindsight. The study findings are in line with literature on defects and the poor use of defect reporting in new residential buildings. The current challenge for defect rectification by house developers after handover is real and this could increase the confidence that new home owners can have in their developers. Defect reporting could confer benefits to new residential building quality in New Zealand and should be embraced as part of a wider best practice.

    Sustaining construction organisations in NZ: A linear regression model approach to analysing determinants of their performance
    (MDPI AG, 2023) Alqudah HE; Poshdar M; Oyewobi LO; Rotimi JOB; Tookey J
    The characteristics, strategies, capabilities, and resources of an organisation contribute to its competitive advantage and superior performance. A model to explain performance differences in the New Zealand context will be developed by examining the relationships between construction organisational performance and these constructs. The information was obtained using a questionnaire survey. A total of 101 organisations participated in the research. For the instrument used to elicit data, the literature was used to identify indicators associated with characteristics of organisational strategies for competition, resources and capabilities, and performance of the organisation. Analyses of descriptive, parametric, and linear regression were conducted to examine the effects of these constructs on organisational performance. The results suggest that organisational characteristics are significantly associated with internal business processes, learning, and the growth perspectives of an organisation’s performance, while competitive strategies, resources, and capability perspectives are significantly related to financial perspectives. As a result, these findings add to the current discourse regarding organisational performance differentials in the construction industry. The study demonstrates that it is critical to take into account the different organisational characteristics that are implemented within organisations and how they influence organisational performance beyond rational processes.
