Point Cloud Completion For Mep Components Using Deep Learning Techniques, Hongzhe Yue, Qian Wang, Yangzhi Yan, Zhouzhou Yang, Mingyu Zhang

CIB Conferences

Point clouds are increasingly leveraged for as-built model reconstruction of facilities, and these reconstructed models play a key role in applications for digital twins and sustainable building. However, point clouds of Mechanical, Electrical, and Plumbing (MEP) systems often experience extensive occlusions, which heavily affect the performance of model reconstruction. To tackle this problem, this study adopts deep learning (DL)-based point cloud completion algorithms to complete occluded MEP point clouds. To overcome the scarcity of datasets, this study utilizes parametric BIM modeling and occlusion simulations to generate point cloud datasets for MEP components. Based on generated datasets, the effectiveness of PoinTr …

Smart City Digital Twin: A System-Of-Systems Approach, Rana Khallaf, Chimay Anumba, Gabriel Castelblanco, Makarand Hastak

CIB Conferences

The concept of smart cities has emerged to battle the problems facing cities from rapid urbanization and mismanagement of resources. In order to monitor and control these large-scale environments such as cities, digital twins were proposed. These digital twins represent a large-scale environment virtually and connect it to the physical world. However, complexity arises when studying these cities. A city is a complex system of interconnected systems, or a system-of-systems (SoS), according to definitions by systems engineering. To understand how SoS can be applied to a smart city digital twin, a literature review is first conducted on SoS applications in …

The Reluctance Of A Self-Selected Cohort Of Construction Managers In Ireland To Report Work-Related Stress., Patrick J. Bruce Dr., Victor Hrymak Dr, Carol M. Bruce Dr

CIB Conferences

Workplace stress in the construction sector is reported to have negative implications for employees and work practices. Although much literature exists on workplace stress, one relatively unexplored area within the field, is the reporting of stress-related concerns. This study investigated the hesitancy to report workplace stress from a sample of construction managers in Ireland. Using semi-structured interviews and interpretative phenomenological analysis, 25 construction managers were interviewed about their reluctance to report workplace stress to their employers.

Stakeholder Partnership Barriers Towards Achieving Net Zero Carbon Building, Justina Falana, Robert Osei-Kyei, Vivian Wy Tam

CIB Conferences

As the world is shifting towards achieving NZC (net zero carbon) by 2050, the building sector is acknowledged as a promising way towards achieving this objective. Besides, the transition towards NZCB (net zero carbon building) has been slow. This calls for the immediate attention and partnership of the stakeholders to assist in achieving carbon emissions reduction in the building sector. However, even though realizing NZCB relies on effective stakeholder partnerships, it is still a struggle for these stakeholders to syndicate. Nevertheless, only limited studies have adequately explored the barriers impeding the effective partnership of the stakeholders in delivering NZCB. Meanwhile, …
