An estimation framework for building information modeling (BIM)-based demolition waste by type

Abstract

Most existing studies on demolition waste (DW) quantification do not have an official standard to estimate the amount and type of DW. Therefore, there are limitations in the existing literature for estimating DW with a consistent classification system. Building information modeling (BIM) is a technology that can generate and manage all the information required during the life cycle of a building, from design to demolition. Nevertheless, there has been a lack of research regarding its application to the demolition stage of a building. For an effective waste management plan, the estimation of the type and volume of DW should begin from the building design stage. However, the lack of tools hinders an early estimation. This study proposes a BIM-based framework that estimates DW in the early design stages, to achieve an effective and streamlined planning, processing, and management. Specifically, the input of construction materials in the Korean construction classification system and those in the BIM library were matched. Based on this matching integration, the estimates of DW by type were calculated by applying the weight/unit volume factors and the rates of DW volume change. To verify the framework, its operation was demonstrated by means of an actual BIM modeling and by comparing its results with those available in the literature. This study is expected to contribute not only to the estimation of DW at the building level, but also to the automated estimation of DW at the district level.

Analysis of Waste Generation Characteristics during New Apartment Construction—Considering the Construction Phase

“…There have been no recent studies on the WGR of CW, and recent building sizes or site characteristics have not been properly considered. Table 2 compares studies on the WGR of CW [24]. These previous studies exhibited significantly different WGRs and classified CW into 3–13 types.…”

“…Therefore, research is needed on calculating the unit generation rates by classifying C&DW by use and structure [22]. In recently, there have been studies that estimate C&DW generation using Building Information Modeling (BIM; e.g., quantity take off), but they have limitations that cannot reflect various characteristics of actual construction sites (e.g., [23,24]).…”

Managerial Areas of Construction and Demolition Waste: A Scientometric Review

“…BIM with all the information from the design stage to the demolition stage of the building has potential advantages for predicting the amount of CDW at the project level [ 83 ]. Through extracting material and volume information from BIM, it is possible to automatically estimate the waste generation not only from the construction stage but also from the demolition stage in the early design stage [ 84 ]. In addition, to accurately forecast the waste production based on building stock at the regional level, the geographic information system (GIS) presents as an innovative approach to assessing the amount of demolition waste [ 85 ] and monitoring the demolition activities [ 86 ] in space and time.…”

“…With the rapid development of information technology, more and more new technologies and methods are applied to construction projects, such as BIM, RFID, GIS, GPS, and big data. For instance, Kim proposed a BIM-based method that calculates demolition waste in the design phase [ 84 ]. Akinade developed a BIM-based model to determine the deconstruct ability in the design stage [ 121 ].…”

Pricing Strategy of Construction and Demolition Waste Considering Retailer Fairness Concerns under a Governmental Regulation Environment

“…Various problems concerning C&D waste management have also aroused widespread concern in academia recently. Many scholars have quantified and estimated the generation rate of C&D waste [8,9,10], and some have studied the applicability of emerging digital technologies such as big data and BIM (Building Information Modeling) in C&D waste management [11,12]. At the same time, focusing on the type of waste materials (such as concrete, asphalt, and brick) [13,14,15] and studying the waste material properties have also become mainstream directions of research.…”
