RESBIM- Research and development of a BIM-based geo-referenced CDW information management system.
In order to implement a true circular economy it is necessary to make significant progress in the level of data we have on Construction and Demolition Waste (C&DW). The type of information we are dealing with in this project is data on the availability or supply and need or demand for CDW.
In the RESBIM project we created a completely new workflow for the use of CDW by addressing different aspects. On the one hand, we automated the collection of information (quantities, typology and coding) on CDW from BIM models for new construction, renovation and demolition.
At the same time, we take this information to geographic information systems (GIS) to solve the second need: to locate waste in space in order to be able to access it in a proximity market.
The RESBIM project covers the part of research and development necessary to obtain a system capable of calculating the waste on a BIM model, extracting it and positioning it on an open GIS model so that the agents of the sector can know the supply of recycled CDW elements that exists or will exist at the time they are demanded and in the place where they are demanded.
Including the calculation of CDW in the BIM model resolves an existing and necessary need for the digital transformation of the construction sector and the promotion of a circular supply chain to go hand in hand and aligned. Likewise, we present the ability to localise the supply of CDW in a system with geographical components that are essential to unlock a barrier for CDW: the great penalty they suffer when competing with primary materials when they have to travel long distances. These distances not only often eliminate economic viability, but also derail the expected environmental improvement.
RESBIM results in an automated information flow from BIM to GIS in a seamless way, without complicating the work for the project managers but providing valuable information for all parties.
This project is financed through a grant from the Instituto de Fomento de la Región de Murcia aimed at the Technological Centres of the Region of Murcia, Modality 1: R&D Projects, co-financed by 80% by the ERDF global grant.
