Value Stream Mapping of Project Lifecycle Data for Circular Construction

Abstract

With The Aim Of Shifting From The Traditional Linear Flow Of Resources In The Construction Industry Into A Circular Model, Several Studies Have Focused On The Reuse And Recycling Of Construction And Demolition Waste. The Present Study Focuses On The End-Of-Life (EoL) Decision-Making For Built Facilities, Including Buildings And Infrastructure, To Support Such A Shift. We Look At The Involved EoL Decisions Through The Lens Of ‘Information Requirements’ And Try To Envision An Information Supply Chain, In Parallel With The Facilities’ Lifecycle Stages, To Support Such Decisions. We Examine Available Data Acquisition Techniques, Data Analysis Tools, And Information Standards That Can Help In Creating And Maintaining An Up-To-Date View Of The Built Facility’s Materials/Components/ Subsystems And Their Location, Condition, Residual Value, Remaining Life, Second Life Attributes, Etc. Through Digital Twins. We Suggest A Value Stream Map For Capturing And Updating Such Information And Identify Technological Requirements And Barriers To Its Realization In Practice.
