Deconstruction and Recovery Information Modelling (DRIM): A Tool for identifying and reclaiming valuable materials at end-of-life of Buildings

More than 50,000 buildings are demolished yearly in the UK leading to huge demolition waste that ends in landfill (Power,2014). It is noted that demolition waste comprises significant proportion of valuable building materials that could be re-usedfor new constructions or refurbishment if recovered properly. However, no such tool currently exists that can help inidentification of valuable building materials for reuse & recycling. The overall aim of this project is to develop anintelligence-based tool called Deconstruction and Recovery Information Modelling (DRIM) that will enable identification ofreusable and recoverable building materials at end-of-life of a building. DRIM Tool will enable: (i) production ofdeconstruction plan; (ii) simulation of deconstruction process; (iii) production of deconstruction protocols during demolitionof the building to enable efficient recovery; (iv) improved demolition waste collection schemes. The tool is aimed at bothnew and existing buildings sector. The Tool will use innovative technologies that include ontologies, NoSQL and big dataanalytics to capture and predict end-of-life properties and value of building materials. It is about circular economy in theconstruction industry.Methodology and Plan: This is a 24 Months (M) project of 8 Work Packages (WP): (i) WP1 - Data collection on Materialsproperties using workshops with Designers and Suppliers - Month 1 - 6 (6M); (ii) WP2 - Creation of Semantic Store withEnd-of-Life Material Properties - Month 4 - 9 (6M); (iii) WP3 - Creation of Big Data Analytics Simulation Platform - Month 7 -12 (6M); (iv) WP4 -Prototype DRIM Development - Month 9 - 12 (4M); (v) WP5 - Full DRIM Development - Month 13 - 21(9M); (vi) WP6 - Security & Testing of DRIM tool - Month 22 - 23 (2M); (vii) WP7 - Exploitation and Dissemination - Month 4- 24 (21M); and (viii) WP8 - Project Management - Month 1 - 24 (24M). - (Please see Appendix B for Gantt Chart).Key Milestones, Deliverables & Realistic Timelines: WP1 - Gigantic Dataset of Material Properties @ M6; WP2 - Databasestorage of End-of-Life Material Properties @ M9; WP3 - Big Data Analytics based Simulation Platform @ M12; WP4 -DRIM Prototype @ M12; WP5 - DRIM Full System @ M21; WP6 - Packaged DRIM Tool @M23; WP7 - Exploitable &Dissemination Outputs @ M4 to M24; and WP8 - Quarterly Project Reports & Meetings.Clear Management Reporting Lines: Lara Ayris from Waste Plan Solutions Ltd. (WPS) will project manage and coordinateproject resources, with the support of Project Administrator and Exploitation Manager for wider roll-out. ProjectManagement Board (PMB) will be set to drive project, monitor project progress and provide relevant advice. UsingPRINCE2 methodology, Task managers for each WP will (i) manage day-to-day project activities (ii) meet with their WPteam on weekly basis (iii) meet monthly (iv) report quarterly to the PMB about work progress . - (Please see Appendix B forProject Management Structure).Rival Solutions: None of the existing waste tools within the industry (i.e. ArchiCAD, Revit, SMARTWaste, WRAP Netwaste,etc.) has deconstruction and material recovery functionality. The DRIM tool is therefore unique within the industry. It willprovide a simulation platform to benchmark the whole-life sustainability of designs in terms end-of-life re-usable, recyclableand recovered materials.Alternative R&D Strategies: Concurrent Engineering (CE) model which is based on parellelization of tasks (WorkPackages) will be used as a R&D approach for this project, as compared to traditional waterfall model where tasks arecarried out sequentially. CE will therefore enable R&D completion within 2 years of project duration.
