This article is the second part of a two-part study, which explored the extent to which Building Information Modelling (BIM) is used for End-of-Lifecycle (EoL) scenario selection to minimise the Construction and Demolition Waste (CDW). The conventional literature review presented here is based on the conceptual landscape that was obtained from the bibliometric and scientometric analysis in the first part of the study. Seven main academic research directions concerning the BIM-based EoL domain were found, including social and cultural factors, BIM-based Design for Deconstruction (DfD), BIM-based deconstruction, BIM-based EoL within LCA, BIM-aided waste management, Material and Component Banks (M/C Banks), off-site construction, interoperability and Industry Foundation Classes (IFC). The analysis highlights research gaps in the path of raw materials to reusable materials, i.e., from the deconstruction to M/C banks to DfD-based designs and then again to deconstruction. BIM-based EoL is suffering from a lack of a global framework. The existing solutions are based on local waste management policies and case-specific sustainability criteria selection. Another drawback of these ad hoc but well-developed BIM-based EoL prototypes is their use of specific proprietary BIM tools to support their framework. This disconnection between BIM tools and EoL tools is reportedly hindering the BIM-based EoL, while no IFC classes support the EoL phase information exchange.

Resumo Normas relacionadas à gestão de Resíduos de Construção Civil (RCC) estão vigentes no Brasil há mais de uma década. O intuito dessa gestão é amenizar os impactos ambientais decorrentes do gerenciamento indevido desses resíduos. O objetivo do presente trabalho é investigar a conformidade técnica e legal de sistemas de gerenciamento de resíduos de construção civil no município de Curitiba. Para tal, elaborou-se uma lista de verificação baseada nas normas em vigor e em alguns modelos de certificações ambientais, como: LEED, AQUA, CASBEE, BREAM e HQE. 24 obras de edifícios residenciais e comerciais foram  visitadas — com ou sem certificação ambiental. Essa lista de verificação foi aplicada nas construções, para realizar um diagnóstico do setor. Apesar da gestão de resíduos ser obrigatória e restritiva à obtenção dos certificados de conclusão de obra, os resultados da pesquisa demonstraram que há problemas na segregação, acondicionamento e transporte dos resíduos. Entretanto, a falta de conscientização e a aparente conformidade documental não se traduz em efetivo gerenciamento dos RCC. Palavras-chave: Resíduos de construção e demolição. Gestão de resíduos. Resíduos sólidos. Auditorias ambientais. Abstract Standards related to the management of Construction Waste (CW) have been in force in Brazil for more than a decade. The goal of this management is to alleviate the environmental impacts resulting from the poor management of these wastes. The objective of this work is to investigate the technical and legal compliance of construction waste management systems in the city of Curitiba. To this end, a checklist was drawn up based on current standards and on some models of environmental certifications, such as: LEED, AQUA, CASBEE, BREAM and HQE. 24 works of residential and commercial buildings were visited — with or without environmental certification.  A checklist was applied, in these buildings, to promote a diagnosis of the sector. Although waste management is mandatory and restrictive to obtain building completion certificates, the research results showed that there are problems in the segregation, packaging and transport of waste. However, the lack of awareness and the apparent documentary compliance does not translate into effective management of the CW. Keywords:  Construction and demolition waste. Waste management. Solid waste. Environmental audits. Resumen Normas relativas a la gestión de Residuos Sólidos de Construcción Civil (RCC) están vigentes en Brasil hace más de una década.

Construction and demolition waste (CDW), as the main consequence of construction and demolition (C&D) activities, has severely affected our sustainability needs. However, construction and demolition waste management (CDWM) lacks the integration of sustainability concepts. Thus, there is a great need to include sustainability dimensions in CDWM to reach sustainable construction and demolition waste management (SCDWM). This study aims at empirically investigating SCDWM by analyzing the impacts of factors that contribute to sustainability aspects of CDWM on waste management hierarchy (WMH), including reduce, reuse, recycle, and disposal strategies. According to the literature, 26 factors were initially identified and grouped under four categories, namely environmental, economic, social, and administrative, that contribute to sustainability aspects of CDWM. Subsequently, a pilot test was performed to assess the significance and applicability of these factors in the Malaysian construction industry by implementing the express analytic hierarchy process (EAHP). Then, a questionnaire survey was performed to collect data from 132 construction companies involved in CDWM. Partial least squares-structural equation modeling (PLS-SEM) was used to test the hypothetical relationships by applying SmartPLS software. Results demonstrated that the economic aspect of CDWM (main category) and “public environment contamination due to illegal waste dumping” (sub-category) were the most influential factor in SCDWM in Malaysia.
