Pycharm Community 2020.1.2 (using Python 3.9.6) was used for the experiment and analysis, in this experimental study. The findings effectively showed that the suggested LSTM model's prediction performance, with a training and testing ratio of 90:10, was determined to have a mean square error …

Self-Supervised Learning Framework For Automated Material Grouping Of Demolition Waste: Advancing Sustainable Waste Management, Ahmad Alshami, Juyeong Choi

CIB Conferences

The construction and demolition (C&D) sector generates significant waste, necessitating efficient sorting and recycling to promote sustainable waste management. Traditional sorting methods in C&D waste management often depend on manual processes, which are labor-intensive and prone to errors, thus limiting recycling efficiency. While automated sorting systems have been introduced, they face challenges with the complex, heterogeneous nature of C&D debris and require large datasets that are manually labeled—meaning every image must be tagged with material types by experts—for training. This study addresses this gap by developing a self-supervised learning framework that reduces reliance on labeled data for effective feature extraction …

Developing A Circular Economy Checklist For Designing Modular Buildings: A Case Study In Sri Lanka, Kaveesha G. Dewagoda, Mohan Kumaraswamy, Ji Chen, S. Thomas Ng, Thilak Jayathunga

CIB Conferences

Climatic change and its impact on humankind is increasingly evident. Being the species that brought about this devastation, our interventions are now needed to proactively and paradigmatically change production and consumption patterns. Circular Economy (CE) is one such sustainability-friendly goal that is gaining traction in the Building Construction Industry (BCI). Given the massive negative impact that BCI has on the environment in terms of resource consumption, carbon emissions and waste generation, design practices must be shifted from object-centric thinking to a systemic & systematic endeavour. Even though Off-Site Construction (OSC) and Design for Manufacturing and Assembly (DfMA) have circular potential …

physically demanding work, such as construction. This narrative review synthesises existing literature examining the relationship between menstrual cycle phases and workplace productivity and discusses implications for the construction industry. The review analysed 40 peer-reviewed publications from 2008-2024, identified through systematic database searches. Findings reveal that menstrual cycle phases …

The True Environmental Cost Of Data Centers: An Insight Into The Construction Phase Of The Era Of Artificial Intelligence, Juan D. Núñez-Morales, Yoonhwa Jung, Mani Golparvar-Fard

CIB Conferences

In recent years, there has been a significant adoption of commercial applications of Artificial Intelligence (AI). These applications have created a demand for infrastructure that support data storage, mining, and throughput compute power services, commonly known as data centers. This demand, which is projected to substantially increase over the next decade, places data centers to be a major contributor to the construction industry's global carbon emissions. However, with research mostly focusing on minimizing carbon emissions during the operation phase of most buildings, environmental impacts incurred during their construction phase are still deserving a deeper study. To address this gap, this …

A Discussion On Sustainability In Terms Of Building Production And Use For Smart Urbanization, Salih Demirkaya, Harun Tanrivermis, Deniz Besiktepe, Yesim Tanrivermis

CIB Conferences

Technological developments and population growth have caused many effects in the construction sector and triggered developments in the construction of cities. Effects such as energy use, construction conditions, building economy draw attention as a war of technology and naturalness within the framework of the concept of sustainability. Constraints such as the need for building production and capacity increase needed by the population, labor and resource use are effective in decision-making. While technology enables the building sector to produce rapidly, it causes negative effects on the balance of nature. Production factors should be evaluated with a holistic approach and systems that …

Insights Into Flow Planning In Construction: The Benefits, Challenges And Implementation, Muhammad Amir Hamza Khan, Robert M. Leicht Phd

CIB Conferences

Despite the productivity gains associated with Lean Construction over the past three decades, the construction industry is still far from the improvements seen in other sectors. One aspect that has been misunderstood and poorly harnessed in construction is flow due to the differing nature of construction projects compared to manufacturing, diverging comprehension of flow, variable production rates across trades, complex logistics for tools, labor, and equipment, and the lack of a holistic model to assess flow on construction projects. This paper discusses the benefits, challenges, and procedural steps for flow planning and implementation on construction projects by interviewing 12 construction …

Women remain significantly underrepresented in technical, trade, and leadership roles, with the majority occupying clerical or administrative positions. This study systematically categorises existing gender diversity policies in the construction sector using the Behavioural Change Wheel (BCW) framework to identify gaps and opportunities for improvement. A systematic literature review was conducted using the PRISMA methodology, analysing peer-reviewed studies and reports published over the last 30 years. The identified policies were mapped to the BCW’s seven categories: communication/marketing, guidelines, legislation, regulation, fiscal measures, environmental/social …

A Life Cycle Approach To Circular Economy In Construction: Strategies For Sustainable Transformation, Bimali Rathnayake, Ruwini Edirisinghe, Tayyab Maqsood, Mayuri Wijayasundara

CIB Conferences

The construction industry’s reliance on linear economic models has resulted in significant environmental challenges, including resource depletion and excessive waste generation. While circular economy principles offer a sustainable alternative, existing research lacks a comprehensive understanding of how these strategies apply across the entire construction life cycle. Many studies focus on isolated stages, such as material procurement or waste management, without considering the interdependencies between life cycle phases. Additionally, there is a gap in structured frameworks that guide construction companies in implementing circular practices effectively. To address these gaps, this study conducts a thematic literature review of 70 peer-reviewed studies to …

Rethinking Sustainability Of Modular Integrated Construction For High-Rise Buildings: Dialectics In System Boundaries, Wei Pan, Zhiqian Zhang, Yang Zhang, Siwei Chen Mr

CIB Conferences

Modular integrated construction (MiC) has been adopted in over 100 building projects in Hong Kong. The sustainability of MiC may vary from different socio-technical contexts such as module designs, which however has not been systematically understood. Therefore, this paper aims to systematically examine the sustainability of MiC for high-rise buildings in a dialectical manner. The examination emphasizes systems thinking of MiC from multiple perspectives such as various performance indicators, building types and modular systems, i.e. dialectics in system boundaries. A new concept of total factor sustainability (TFS) is proposed for systematically examining the dialectics of MiC sustainability. TFS is measured …
