Validating construction project data for a Digital Twin The process of providing as-built information in a facility’s Digital Twin.

Abstract

The facility management and operational stakeholders of a building are today widely relying on information provided from the design phase of the building project. To ensure that more relevant and accurate information is generated, the industry has embraced the Digital Twin. The Digital Twin’s purpose is to mirror the geometry of the physical asset in a digital manner while also connecting it with non-geometrical information, which provides knowledge and insights. The connection between geometrical and non-geometrical information is carried out by utilizing a validation process made in several steps. The process also varies depending on what information is being handled. To gather information from the as-built environment a laser scanning is made to create a point-cloud acting as a geometrical representation of the physical asset. This point-cloud is later connected with non-geometrical information through the process of validation. The process is carried out partly by subcontractors which connects the physically installed objects, scanned into the Digital Twin, to non-geometric information such as product data. The validation is summarized to be a helpful way of structuring information and connecting it to physical positions. However, it has been concluded that what information that is deemed relevant heavily varies between projects and who is going to receive the information. It is therefore suggested to make an early mapping of involved stakeholders interest in what information that should be provided in the Digital Twin.
