Project: Scan To BIM
Client: Dar Al Handasah
Location: Dubai (UAE)
Area: 3 Kilometers
Al Maktoum Airport
Dubai Airport Engineering Department hired GCS to perform Scan to BIM service, later to bring some alterations like retrofitting, renovation, refurbishment, or reconstruction. It is very important to have a detailed and accurate representation of the existing conditions of the building. 5 teams of 3D laser scanning devices were used to capture the existing conditions, the scanned data was in the form of “Points” where more than 10 billion such points were combined together which formulates a Point Cloud Scan. A Point Cloud Scan was then imported into a 3D Modeling platform with the purpose of creating an As-built model.
The intended use of the Scan to BIM process was for: site verification, design validation/planning/comparison, develop as-built drawings, interference checks, MEP or construction elements demolition, addition, documentation of existing building conditions, quantity take-off, and budget estimation.
Execution of a Scan to BIM project was very challenging, to implement the project successfully we made a step-by-step process, which is described below and involves four steps  Capture  Process  BIM Modeling and,  Quality Assurance and all four steps should be executed as per BIM Execution Plan (BEP/BXP) and as per project workflow.
