“…The disassembly and deconstruction analytics tool can also serve as a decision support platform that government and planners can use to evaluate the level of compliance of building designs to circular economy and sustainability requirements. Guerra et al (2019) proposed the use of BIM for the estimation of construction waste based on the delta of construction materials purchased and the materials incorporated into the building structure itself. This tool therefore is not applicable to deconstruction scenarios.…”

Waste from the construction sector poses huge challenges for sustainable waste management. This is not only due to the vast amount of waste produced in construction and demolition activities, but also due to pollutants potentially contained in these products. Subject to these conditions, waste management must ensure recovery of as many resources as possible, while making sure to keep material loops clean. This demanding task requires more knowledge about the existing building stock and an adaptation of current demolition processes. Innovative technologies, such as Building Information Modelling, or modern frameworks, such as Geographic Information Systems, offer a high potential to synoptically provide stock material information for future demolition activities for individual objects to be deconstructed as well as for whole cities as a basis for managing the anthropogenic stock and potential urban mining. Suitable methods of data collection allow for acquiring the desired input for the generation of building stock models enriched with demolition-related information. With the latter, selective deconstruction strategies as well as appropriate waste stream routing agendas can be planned and executed, thereby securing safety at work during the demolition process itself and a waste stream routing according to the waste hierarchy. This review article gives an overview of currently deployed building material assessment tools (data capture and visualisation), both a prerequisite for improved information on materials and geometry (and thereby mass/volume). In addition, this article describes workflows employable for the purpose of urban mining in end-of-life buildings, of which one holistic approach will be described in depth.

“…The model could estimate waste and identify its origin, type, packaging, and other characteristics. In recent years, some authors, such as Akinade et al (2018), Guerra et al (2019), Kim et al (2017), and Mercader-Moyano et al (2017), have developed and continue to develop models supported on building information modelling (BIM) to estimate waste generation based on building design. Akinade et al (2018) used BIM and neural networks to generate a model that could integrate into Autodesk Revit as an add-in component.…”

“…Mercader-Moyano et al (2017) used BIM combined with the cost database of Andalucía (Spain) to calculate steel and concrete waste. Guerra et al (2019) provided a study based on automatic measurements on BIM comparing them with purchasing records on an educational building, specifically to concrete and drywall. This approach obtains an estimate of the generated waste, which is useful in the preconstruction phase.…”

Modelling waste generated during construction of buildings using regression analysis

et al. 2019

The building industry is responsible for a large amount of waste, and the measurement and modelling of this waste could be used to develop better waste management plans. Several theoretical models explain the relationships between waste and building characteristics, but local practices may result in different behaviours. This study aimed to measure and analyse the waste generated through construction. It was based on the analysis of 18 building sites located in the region of Porto Alegre, Brazil. Waste was measured at these sites, and the results showed an average waste generation rate of 0.151 m3 m-2. A regression analysis of the collected data presented a satisfactory performance in two models. The first model was developed to explain total waste generation, including the effects of certain attributes, with an R2 = 0.81. The changes in waste generated during construction were estimated. The second model considered time schedules and examined the effect of the construction stage on waste generation, and reached an R2 = 0.91. The model with time indicated an S-shaped relationship. The models presented satisfactory statistical parameters and could be used to produce better waste management plans in the preconstruction stage.

“…In addition, with the continuous demolition of waste buildings in the process of urbanization, the annual output of construction solid waste in China is increasing. However, compared with Europe, Japan and the United States, the utilization of construction solid waste in China is very low at less than 5% of the annual output [3][4][5][6][7]. The contradiction between the shortage of building materials and the high output of construction solid waste caused by urbanization has brought great pressure and challenge to the sustainable development of China's resources and the environment [8][9][10].…”

In this paper, the properties of sulphoaluminate based recycled concrete, with high workability and low and medium strength, prepared by recycled powder (RP), recycled coarse aggregate (RCA), and high belite sulphoaluminate cement (HBSAC), were systematically studied. Under the condition of a water binder ratio of 0.45, sulphoaluminate based recycled concrete, with different mix proportions, was prepared by replacing sulphoaluminate cement with RP and natural coarse aggregate (NCA) with RCA. The workability, mechanical properties, durability, and hydration products of the prepared concrete were analyzed. The results showed that when RP and RCA were used together, the workability of recycled concrete could fully meet the pumping demand in actual construction. When the mass replacement rate of RP was less than 30% and that of RCA was less than 20%, the strength of recycled concrete could completely reach the design strength grade, while those that did not reach the design strength grade could reach the next grade. The durability performance was also good.
