Quantification of Construction Waste in Early Design Stages Using Bim-Based Tool

Construction and demolition waste represents a growing environmental, social, economic problem, has become priority for European worldwide policies. The early quantification of construction is essential the minimisation its production improvement management. This requires development design-based tools that enable better understanding expected produced during phase. Building Information Modelling (BIM) methodologies have gained recognition in Architecture, Engineering, Construction, Operations (AECO) sector, largely due to their capacity data simulation, storage, management building design study presents software application, called WE-BIM Add-in, quantify (CW) while designing BIM model Revit. A validated CW which enables types quantities per element be predicted detail according List Waste (LoW) integrated into Revit workflow. Design alternatives could effortlessly simulated real time assist practitioners decision-making stages. Two alternative structural systems Spanish residential were compared: reinforced concrete structure, Option 1 (O1), steel 2 (O2). results obtained automatically: O2, addition reducing 56% O1′s waste, would increased recycling rate by 49%; displayed Revit, thereby remaining consistent with those other studies compare prefabricated situ systems. work provides basis future research automated estimation useful tool waste-prevention
