Item New Zealand's response to the COVID-19 pandemic and the effects of its governance on the construction industry(IOP Publishing Ltd, 2022-01-01) Mirhosseini SF; Wilkinson S; Babaeian Jelodar MThe global COVID-19 pandemic has impacted the construction industry. The pandemic caused wide international disruption to employment, supply chain, costs, skills, and other aspects, and it caused huge uncertainty. Around the world, governments dealt with the crisis in different manners. This study investigates the ways New Zealand responded to this pandemic and examined the effects of its governance on the construction industry. This is done through examining and analysing government records and guidelines in response to COVID-19 at different stages and alert levels. Relevant government information portals and websites such as "Ministry of Business, Innovation and Employment", "Construction Sector Accord", and "Covid.govt.nz"are investigated to find guidelines and information to help the construction industry respond to the impacts of COVID-19. These guidelines and information were compared to understand how similar these recommended responses were. The findings show the mitigating implications and solutions to the construction industry's current disruption and demonstrate the similarity of the recommended solutions.Item 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 JOBMotivation: 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%.Item Classification of rework root causes in the design stage of projects for contract assessment(IOP Publishing Ltd, 2022-01-01) Asadi R; Rotimi JOB; Wilkinson SRework is one of the leading causes of cost and time overruns that primarily affect project performance. The performance of construction projects can be elevated with the implementation of rework moderation strategies. Identifying rework root causes is the first step of rework management followed by a mitigation approach, reducing or preventing strategy. As the contract is the core connection between clients and contractors, using a rework management approach in the contracting process allows participants to be aware of rework impacts before the project's commencement. Selecting the best approach for rework mitigation depends on rework causes and their classified roots. Thus, the paper classifies rework root causes in the design stage of projects to provide a platform for contract documents assessment. The method used to classify the identified rework causes into five categories was designed on the literature. Results from collecting secondary data indicated all categories in the design stage, consisting of technical, human resources, process, material/equipment, and other general factors. The next step of the study is to assess contract documents through a questionnaire based on these classified factors in search of a connection between rework, contractual claims, and clauses of the contract. The paper recommends that assessing contract documents can be used as a new approach for rework management.Item A taxonomy of pedestrian evacuation infrastructure for urban areas; An assessment of resilience towards natural hazards(IOP Publishing Ltd, 2022-01-01) Fathianpour A; Jelodar MB; Wilkinson S; Evans BMany people in the world live in hazardous environments and are susceptible to disasters. In the time of a destructive event, a resilient community must be prepared to mitigate the event and quickly respond. An effective mitigation plan can lead to fewer fatalities and damages. One of the most critical tasks for mitigation is the evacuation process. Wherein short notice time, overcrowding, bottlenecks in infrastructure and challenging terrain and topography may worsen the situation. Amongst other things, the evacuation process encompasses transportation infrastructures referred to as corridors, signs, pedestrian footpaths, and/or shelter infrastructures for keeping people safe. Evacuation infrastructure can also become damaged after the event; therefore, it's imperative to have a robust assessment of different evacuation infrastructures. This study will investigate the characteristics of the available evacuation infrastructure and outline the general drawbacks. A systematic methodology for reviewing articles has been implemented to understand how vulnerable cities can be more prepared, especially for pedestrian evacuation. An evacuation scoring system for pedestrians will be developed to investigate evacuation infrastructure in terms of different resilience features, such as redundancy, safe to fail, readiness, capacity. The most practical evacuation system will be estimated, with a final output being to provide the features of a successful pedestrian evacuation system for future policy use.Item Zero carbon refurbishment for existing buildings: A literature review(IOP Publishing Ltd, 2022-01-01) Bui TTP; Domingo N; Macgregor C; Wilkinson SThe need to mitigate climate change calls for the construction industry to achieve net-zero greenhouse gas (GHG) emissions for new and existing buildings by 2050. Zero carbon refurbishment (ZCR) for existing buildings is a significant area of interest, as many existing buildings will still be there in 2050. This paper investigates the global development, knowledge structure and gaps in the research field by conducting a systematic literature review. The final selection of 147 up-to-date journal articles was analysed using mixed-method data analysis, including quantitative (science mapping) and qualitative (thematic) analysis. Quantitative results reveal evolving research topics including energy performance and efficiency, life cycle environmental impacts, energy resources and policy, and decision-making with multi-objective optimisation. Research in ZCR is well-established in European countries and there is much interest and activity around the world. ZCR research on residential and office buildings provokes much consideration compared to other building types. The qualitative findings discuss the mainstream research areas (e.g. decision-making with multi-objective optimisation), determines research gaps (e.g. carbon impact), and recommends the future research agenda. The study offers academics a comprehensive understanding of ZCR research to link current research areas into future trends. It also provides construction professionals with current practices and an interdisciplinary guide to better deliver ZCR projects.
