THE FUTURE OFFSITE CONSTRUCTION & DIGITAL ENGINEERING MATHEW RILEY MANAGING DIRECTOR, RAMBOLL UK

DRIVERS FOR CHANGE

PRODUCTIVITY

MODERNISE BY CONSTRUCTING OFF SITE Client benefits Enable informed decisions earlier Faster delivery Create better quality in less time De-risk the programme downstream Lower costs

MODERNISE THROUGH DIGITALISATION Digitalisation Conceiving tools that speed up the analysis of design to: Increase productivity Improve quality Go further faster

COMBINING EXPERTISE IN OFFSITE CONSTRUCTION & SKILLS IN DIGITALISATION

OFFSITE CONSTRUCTION & DFMA Design for Manufacture and Assembly (DfMA) Combining design for ease of manufacture and design for ease of assembly in a lean approach Manufacturing done off site in a safer, controlled environment with higher quality control Assembly on site uses fewer site operatives and at a faster speed

BENEFITS OF DFMA Higher quality control Increased knowledge transfer Lower financial risk DfMA Accurate coordination Greater material quantity certainty Reduced assembly time

It costs too much There is no architectural freedom You can t insure the building It won t last 50 years The connection design is difficult Design is too restrictive It will feel prefab No one knows how to design with it The supply chain is not developed

AUTOMATING BIM POINT CLOUDS TO 3D OBJECTS

WHAT IS A POINT CLOUD? Millions or even billions of individual XYZ coordinates So dense they often appear solid Commonly captured by laser scanning Based on the time-of-flight of a laser beam hitting target and returning to sensor

PROCESS Point cloud Edgewise processing Revit model

AUTOMATED (1 CLICK) MODELLING 1 click pipe model 1 click operation finds 50-75% of the walls and pipes Easy to use tools to clean up and finish model Time savings of at least 50% over manual modelling Improved accuracy and QA After clean up

ASSISTED MODELLING For structure, user guides process by selecting type of structural element and region of points Time savings of at least 25% over manual modelling Improved accuracy and QA Particularly effective for non-horizontal or vertical members
