    Benefits, constraints and enablers of modular offsite construction (MOSC) in New Zealand high-rise buildings
    (Emerald, 2023) Shahzad WM; Reddy SM; Kahandawa R; Rotimi JOB
    Purpose: The ascendancy of modular offsite construction (MOSC) over traditional construction methods is well known. Despite the known potential of this construction approach, its adoption is minimal in New Zealand construction industry. This article investigates the potential benefits of using MOSC for delivery of high-rise buildings in New Zealand, underlying factors responsible for its low uptake and the measures that can facilitate its improved uptake. Design/methodology/approach: This study utilised a mixed research approach. An empirical questionnaire survey was carried out with New Zealand construction industry professionals with expertise in MOSC. Factor analysis of survey data was carried out using SPSS software. Semi-structured interviews were carried out with subject matter experts to get further insights and expand the survey findings. Interview data were analysed using thematic analysis. Findings: Study identified benefits of MOSC, thus establishing potential of its uptake for high-rise building construction. Constraining factors were investigated, most pronounced being low level of skills in construction industry to design, manufacture and integrate supply chain of MOSC, high initial investment, high cost of importing modules and negative perception about offsite manufactured buildings. This study also highlighted the enablers to improve uptake of MOSC. These enablers included; loan and mortgage policies to suit MOSC paradigm, building regulations to support OSC industry, increased support from the government and awareness and acceptance of standardised building designs among the clients. Originality/value: Originality of this paper harps from little to no research carried out to investigate use of MOSC for high-rise buildings in New Zealand context.

    Blockchain and information integration: Applications in New Zealand’s prefabrication supply chain
    (MDPI (Basel, Switzerland), 2021-12-03) Bakhtiarizadeh E; Shahzad WM; Poshdar M; Khalfan M; Rotimi JOB; Banaitis A
    New Zealand’s rising demand for new and affordable homes is driving innovative and effective methods for project delivery. Prefabrication or off-site construction is considered an innovative approach to project delivery that eliminates the limitations of traditional construction methods. However, the prefabrication industry struggles with several challenges, including poor coordination and low supply chain integration amongst its partner organisations. There has been previous literature on improving the prefabrication supply chain integration, but few studies about the role of technology in this sector. Therefore, this article provides intuitions into the applicability and benefits of advanced technologies, namely blockchain, for improving supply chain integration in the context of prefabrication in New Zealand. A questionnaire survey was used to identify the channels used for information exchange between clients and contractors. Moreover, the questionnaire ascertained the positive effects of blockchain on enhancing supply chain integration between the two partners. Blockchain has proven to be a secure information integration instrument that can improve the integration of the prefabrication supply chain by fostering collaboration between organisations.

    Real-Time Project Productivity Tracking System: Practical Case in Smart Construction Projects
    (School of Built Environment, Massey University, 2022-02-17) Radman K; Babaeianjelodar M; Lovreglio R; Wilkinson S; Ghazizadeh E; Shahzad WM; Rasheed EO; Rotimi JOB
    Motivation: The productivity and progress tracking systems are currently used in construction projects to acquire the site works data and converting to various digital reports. Knowledge gap: To date, capturing and transferring data processes are slow or inefficient because significant human errors occur in the process. Therefore, project managers can omit critical information, and no timely decision can be made related to delay and unproductivity. Aim and objectives: The purpose of this paper is to encompass a real-time project productivity tracking system to register data and manage delays related to an Electrical and Instrument service trade involved in smart construction projects in New Zealand. Research method: The paper aimed to review industries delay reports, use expert judgment experience, and compare the proposed method with current ones. Preliminary or anticipated findings: The finding shows the proposed method uses a combination of smartphone and Ms Project real-time monitoring software to optimise the current site reporting procedure and workflow of productivity managing. Research significance: The presented method should help construction decision-makers enhance time and cost-effectiveness and manage delay better alongside more effective decisions. Meanwhile, hours booked to collect data and update programs and models dropped by 24%.
