Reconsidering digital deconstruction, reuse and recycle processes using BIM and Blockchain

Project description

The main goal of DiCYCLE is to analyze, map, and optimize current End-of-Life (E-o-L) processes in construction, supported by digital technologies—BIM (Building Information Modeling), Blockchain (BC), and Smart Contracts (SC). This aims to create new business models and allow for sustainable, digitalized construction and planning processes that enable the reuse and recycling of building materials and components throughout their lifecycle and clearly define the roles and responsibilities of model stakeholders. The project seeks to support a transparent, recycling-friendly collection and tracking of building components and materials, as well as to minimize construction and demolition waste.

This research focuses on two aspects: on one hand, Building Information Modeling-supported building models (BIM models) that correspond to the actual executed state ("as-built"), and on the other hand, process flows that describe both data changes and executed construction works. Data structures for E-o-L relevant information must be identified and linked with BIM. The integration of necessary data sets and the mechanisms for verification through BC-based technologies and SC will be developed for the reuse and recycling of the materials and components of a continuous digital building model, enabling early E-o-L assessments. Additionally, a framework as a proof of concept will be developed, which will facilitate the implementation of BIM, BC, and SC in E-o-L processes.

Thus, the project represents the continuation of the framework developed in the research projects BIMd.sign and FMChain for the implementation of BC and SC in a BIM-supported planning (BIMd.sign) and operation (FMChain). The innovation of the project lies in the integrative view of E-o-L data and processes, their coupling with BIM, and the verification/tracking through BC and SC.
