• Avoiding potential site revisits for missed data (office base field checking)
• Fast turnaround where access time is restricted (e.g. railway possessions, contaminated areas, live motorways, etc)
• High accuracy plans for retro fitting design work, avoiding on-site alterations and clashes
• A reduction in re-work and ‘fit-up’ problems
• The ability to amend the scope of projects without requiring a return to site
• Avoiding the need for access platforms as the survey is entirely reflectorless
• An archive record of the site at a snapshot in time which can always be accessed even though it may no longer exist in reality !

Benefits can also be in terms of Value added datasets:

• Quick data turn around from site work to data delivery
• Management of scope change more effectively
• Real time checking of the data (scan data can be viewed in real time in the field)
• Massive increase in data available compared to conventional surveys
• Increased safety by using reflectorless survey techniques
• Scan data can be used to validate other forms of survey quickly and efficiently
• Creation of deliverables from raw scan data can be done by the client or end user
• High quality images, animations and visualisations can be created for reports and presentations
• One dataset can be made available to multiple users: e.g. for a rail project
       o OHLE design
       o Structure surveys
       o Signal sighting issues
       o Clearance data
• Laser surveying helps avoid:
       o Assumptions
       o Generalisations
       o Errors in interpretation
       o Problems by having the original data set to refer back to
