An automated system for planning and decision making on deconstruction and demolition supported by a database of EoSL materials and products (opens in new window)

Taking the digital twin model developed in D3.1 as the starting point, the report of deliverable D3.2 will describe how to automate the waste audit, i.e. the planning and decision making on deconstruction and demolition. It will consist of the following main sections: (1) a description of the digital twin of the construction; (2) a database of EoSL materials and products; (3) methodology of optimisation to achieve the highest value of reuse and recycling; (4) quantities of different types of waste materials and reusable components to be extracted from the EoSL construction, based on an optimisation process; (5) recommendation for downstream processing of recyclable materials and reusable components.

Methodology for a material mapping dataset (databank) and C&D waste predictor application/solution integrated in BIM processes (opens in new window)

Development and formulation of a methodology for cloud-based datasets, based on data agnostic platform allowing ease of use and simple workflows through the use of API links into existing design authoring applications used form planning and consturction processes. Such methodology shall define requirements on information which have to be provided about:• Materials /products technical and environmental data are known• Materials/products and systems that use a high proportion of recycled/recyclable material are identified (link to T5.3)• Information about manufacturers who offer ‘return schemes’ for construction waste produced during construction (incl. maintenance and rehabilitation) are identified • Proportions of manufactured material that can be recycled at the end-of-life or even re-used completely new product are defined.• Materials / products that have limited potential for recycling once they become contaminated with other products, e.g., partitions and facades that incorporate lots of products to build up the system including one material bonded to another. This represents one of the approaches how to integrate life-cycle based waste management in the whole digitalized construction process.

Evaluation of current practices and policies in CDW management in EU countries, the UK and China. New technologies and automated solutions (opens in new window)

This evaluation will include the results from subtasks T1.1 and T1.2. The purpose is to perform an assessment in the EU (with specific analyses over a number of EU countries), as well as the UK and China, regarding the following aspects:- Current targets, policies, legislation, standards and certification systems applicable to circular economy in the construction industry, implementation and future trends;- Current waste production in construction and markets of secondary products for construction materials;- Current best practices in the construction sector for waste management;- Identification of barriers, risks and drivers;The purpose of this initial evaluation is to set benchmarks for comparison and allow assessment of impact of this project. Additionally, other industrial sectors will be explored to identify potential technologies, automated and robotic solutions that could be applicable for raising efficiency in CDW management and treatment in different lifecycle stages of a built structure, their readiness for validation, implementation and exploitation.The methods used will be based on:- secondary research, with data and information gathering for synthesis and analysis;- surveys and interviews to different stakeholders involved in CDW management, making statistical analysis of results;- comparison to key performance indices (including economic, social and economic metrics);The results will feed WP2, WP3, WP4, WP5 and WP6.

Guideline to ascertain quality assurance including proposal for revision/generation of harmonized test / product standards (opens in new window)

This deliverable will be presented as a report showing the results from task 5.4 and specially providing the guideline to ascertain quality assurance procedures including the testing requirements both at external laboratories and at the waste manager premises to totally characterize the new products alligning this information with market requirements as analized in task 5.3. The revision of test methodologies and product standards will be presented as well as any proposal to ammend or complement existing methodologies or generate new ones that are suitable for CDW based materials.

Methodology for improved logistics concepts regarding collection and automated management of off-site CDW treatment (opens in new window)

A report will be delivered following common practices in C&D waste collection in terms of by law forced pre-sorting, used types of containers, and typical waste treatments. Furthermore, data about national and European legal requirements will be identified with respect to implementing on-site pre-sorting of waste types following the European waste classification (e.g. is pre-sorting retrieved by law? Are their economic incentives? etc.). Possibilities for new types of waste containers will be described and evaluated to support on-site pre-sorting and where possible suitable modifications of smart (IoT-equipped) waste collection containers will be identified. In parallel suitable concepts for a system (network) of regional centers to provide redistribution of segregated waste materials including variant flow-charts for waste processing and organization will be identified and specified respecting market factors. Finally, recommendations and changes in the regulatory framework for EU will be described by the methodology focusing on aspects like: limits for impurities achievable by automated sorting systems, updated set of characteristics/parameters waste operators at recycling plants will be obliged to monitor and declare, etc.

Digital Information Management System (opens in new window)

The purpose of the digital information management system (DIMS) is to integrate the different stages of CDW management by providing an integrated digital approach to enable waste traceability and management, where built asset project information is managed through the whole life cycle. This approach will establish a standardised information management workflow/process. This in turn, will serve to integrate the key stakeholders, ensuring that the right information is provided and accessible by the right ones, at the right time, providing a single view of the truth of the built asset information model at key stages in the life cycle (i.e., design, construction, operations, deconstruction, new products life), to effectively enable CDW management (e.g. across the demonstrators). The DIMS will be established through the adoption and customisation of a cloud-based collaboration (BIM information model) solution, underpinned by existing standards, protocols, etc. for information management of BIM/digital twins, etc. This will facilitate a seamless flow of the required built asset information through the whole-life and CDW management process enabled through the interoperability of the different tools through open exchange standards. The required aspects of information security, privacy, and confidentiality will also be considered in alignment with relevant standards. Analytics and smart tools will be integrated to demonstrate the real-time dashboarding and reporting of the CDW management information to support more effective decision making. In addition, the tools for CDW management developed in RECONMATIC will be considered to be integrated within the DIMS to further demonstrate the enhancement of the seamless flow of information throughout the process. The operation of the DIMS will be validated through the implementation of the scenarios in the demonstrators in RECONMATIC. A DIMS version will be adapted to the Chinese market, corresponding standards and regulations to be applied, and offering similar potential use for CDW management and waste traceability in the Chinese construction industry.
