Into The Workers' Domain: Witnessing A Construction Site Accident, Richard Brett

CIB Conferences

Construction site safety campaigns, for example ‘zero accidents’, pursue a goal, either genuinely or fantastically, for the way construction sites should perform. Critics accuse the advocates of these lofty goals as being unrealistic to the everyday working nature of construction which will always have inherent and irremovable hazards. When construction site accidents do occur the moment of harm is invariably instantaneous. Witnessing these events first hand, especially as a researcher, is a rare occurrence. While undertaking a short-term ethnography on a building site the author observed a minor accident unfold and captured it with a video camera. The data collected …

A Conceptual Framework For Implementing Digital Twins In Infrastructure Upgrades And Retrofits, Kofi A.B. Asare, Rui Liu, Chimay J. Anumba, Dolly Na-Yemeh

CIB Conferences

The United Nations (UN) Sustainable Development Goal (SDG) 9 emphasizes the need for sustainable and resilient infrastructure. An important pathway to achieving this goal is to upgrade and retrofit existing infrastructure to reduce carbon emissions, which is a top priority of the Bipartisan Infrastructure Law in the United States. Existing research has recognized that Digital Twins (DTs) are valuable for retrofits. Yet, current efforts are fragmented, focusing on specific types of infrastructure, and do not provide an approach that can be applied to the aggregated infrastructure stock. The variety of infrastructure systems makes focusing on DT-based methods for infrastructure upgrades …

Project Cancellations In New Zealand's Construction Industry: Assessing The Impact Of Unpredictable Events, Maryam Tagharobi Ms, Mostafa Jelodar, Teo Susnjak

CIB Conferences

Unpredictable disasters such as climate change, natural hazards, and pandemics disrupt the construction industry, a vital driver of economic stability. Despite preventive measures, the industry faces setbacks, including project cancellations, postponements, and suspensions. These issues are particularly pronounced in large-scale projects, exacerbated by shifting regulations and economic crises, causing broader economic repercussions. In response, government priorities and disaster strategies often reallocate resources among residential, commercial, and civil projects, inadvertently exacerbating postponements and cancellations in some cases. This research addresses these challenges by analysing the impacts of external and unpredictable disruptions on project value and volume in New Zealand's construction industry …

Leung, Dicken Poon, Yuxiu Zu, Yueyang He, Kai Gao, Tim Huang, Clement Pang, Kenneth Leung, Jenny Zhao, K. S. Wong, Edward Ng, Chak Sang Yue, Yuk-Ching Cheung

CIB Conferences

Better urban ventilation can significantly contribute to achieving UN SDGs through better liveability for sustainable cities and communities (SDG 11), better air quality for health and well-being (SDG 3), and more climate-responsive building design for climate action (SDG 13). Aligning with the said goals, a set of guidelines comprising 2-dimensional prescriptive building separation requirements was promulgated by HKSAR's Buildings Department (BD) in 2011 to promote better urban ventilation. However, some practitioners have concerns about applying the guidelines for projects with complex geometries. Projects may adopt alternative assessment methods using wind tunnel or CFD simulations to demonstrate compliance, but the required …

Idenitfying Barriers & Enablers To Improve Whs Outcomes In Australian Small Construction Businesses, Marcus Jefferies A/Prof., Tanvi Newaz Dr, Buddhini Ginigaddara Dr., Temitope Egbelakin Prof., Riza Yosia Sunindijo A/Prof., Liyaning Maggie Tang Dr.

CIB Conferences

Despite its important socio-economic contributions, the Australian construction industry has a poor WHS record. Efforts to improve WHS tend to focus on and be led by, large organisations due to the resources that they have and their ability to capitalise on the economies of scale in their operation. However, it is important to realise that 97% of construction organisations are small businesses, employing fewer than 20 people and their WHS outcomes are worse than the WHS outcomes in large organisations. They are also hard to reach through conventional communication strategies. This indicates that current WHS best practice initiatives are not …

Virtual Reality (Vr)-Based Training In Human-Robot Collaboration: Mediating Role Of Vr Learning Experience, Adetayo Olugbenga Onososen Dr, Musonda Innocent Prof

CIB Conferences
