“…This platform allows stakeholders to monitor material flows and perform negotiations between each other. With the aim of engaging all of the supply chain actors in the decision-making process of public works, the DECORUM project developed a multi-user platform [181]. This platform supports green public procurement by allowing users to assess the circularity and environmental impact of projects, and to develop a marketplace for recycled materials.…”

Circular Digital Built Environment: An Emerging Framework

2021

Digital technologies are considered to be an essential enabler of the circular economy in various industries. However, to date, very few studies have investigated which digital technologies could enable the circular economy in the built environment. This study specifically focuses on the built environment as one of the largest, most energy- and material-intensive industries globally, and investigates the following question: which digital technologies potentially enable a circular economy in the built environment, and in what ways? The research uses an iterative stepwise method: (1) framework development based on regenerating, narrowing, slowing and closing resource loop principles; (2) expert workshops to understand the usage of digital technologies in a circular built environment; (3) a literature and practice review to further populate the emerging framework with relevant digital technologies; and (4) the final mapping of digital technologies onto the framework. This study develops a novel Circular Digital Built Environment framework. It identifies and maps ten enabling digital technologies to facilitate a circular economy in the built environment. These include: (1) additive/robotic manufacturing, (2) artificial intelligence, (3) big data and analytics, (4) blockchain technology, (5) building information modelling, (6) digital platforms/marketplaces, (7) digital twins, (8) the geographical information system, (9) material passports/databanks, and (10) the internet of things. The framework provides a fruitful starting point for the novel research avenue at the intersection of circular economy, digital technology and the built environment, and gives practitioners inspiration for sustainable innovation in the sector.

“…This waste could be grinded on-site to be used as inert aggregate for subsoils (Concretos Reciclados, n.d.) or to make on-site blocks (Yajnes et al, 2017). Nonetheless, many authors propose to use it as inert aggregate in prefabricated blocks (Luciano et al, 2021;Pacheco-Torgal, 2014;Rakhshan et al, 2020). These experimental materials represent a solution to make concrete blocks, but they still lack the required certification, dissemination and acceptance from users, developers and stakeholders (Molar-Orozco et al, 2020;Roux Gutierrez et al, 2015).…”

A construction and demolition waste management model applied to social housing to trigger post-pandemic economic recovery in Mexico

2021

Buildings consume 40% of raw material and primary energy and generate 35% of industrial waste worldwide, making this sector play a main role in raw material depletion, energy consumption and carbon emissions which provoke great environmental impact and worsen Global Warming. Latin American countries including Mexico have the world’s highest urbanisation rate (84%) but lack effective construction and demolition waste (CDW) management to thrive in regenerative sustainability, climate change mitigation and post-pandemic economic recovery. This work applies the Spanish current model to quantify on-site 61 Mexican social housing CDW with surveys to workers and supervisors as an additional source of data. The results of the case study show that social housing consumes 1.24 t.m−2 of raw materials and produces 0.083 t.m−2 of CDW. Cement-based, ceramic and mixed CDW represent 83.44% of total CDW. When considering inert soil as a recyclable resource, 78% of the remaining CDW ends in landfills and only 22% of it goes to recycling plants. The implementation of this methodology will deliver sustainable CDW management in Mexico, by minimising CDW production, promoting related legislation and allowing replacement of current construction materials for eco-efficient ones. Furthermore, these data can broaden the Spanish coefficients of the construction resources that become CDW to build an internationally sourced database.

“…A building may be demolished using various methods or techniques, including (a) blast, (b) wrecking balls, (c) hydraulic crushers and pulverizers, and (d) the top-down process. The method of demolition chosen is determined by the project requirements, site limitations, and equipment availability [74,75]. Demolition sites are typically located in congested areas where space for large machinery such as cranes is often restricted [76].…”

The widespread use of artificial intelligence (AI) in civil engineering has provided civil engineers with various benefits and opportunities, including a rich data collection, sustainable assessment, and productivity. The trend of construction is diverted toward sustainability with the aid of digital technologies. In this regard, this paper presents a systematic literature review (SLR) in order to explore the influence of AI in civil engineering toward sustainable development. In addition, SLR was carried out by using academic publications from Scopus (i.e., 3478 publications). Furthermore, screening is carried out, and eventually, 105 research publications in the field of AI were selected. Keywords were searched through Boolean operation “Artificial Intelligence” OR “Machine intelligence” OR “Machine Learning” OR “Computational intelligence” OR “Computer vision” OR “Expert systems” OR “Neural networks” AND “Civil Engineering” OR “Construction Engineering” OR “Sustainable Development” OR “Sustainability”. According to the findings, it was revealed that the trend of publications received its high intention of researchers in 2020, the most important contribution of publications on AI toward sustainability by the Automation in Construction, the United States has the major influence among all the other countries, the main features of civil engineering toward sustainability are interconnectivity, functionality, unpredictability, and individuality. This research adds to the body of knowledge in civil engineering by visualizing and comprehending trends and patterns, as well as defining major research goals, journals, and countries. In addition, a theoretical framework has been proposed in light of the results for prospective researchers and scholars.
