LASER SCANNING FOR CONSTRUCTION (3 days)
Setting Out For Construction is an Approved Training Organisation
- CITB Assured
- Eligible for Flexible Workforce Development fund, GRANT BACK fund, CITB Skills and Training fund and/or levy grants.
About This Course
Delegates should have a working knowledge of 3D coordinate geometry, surveying and setting out principals and 3D mapping and modelling software.
This 3- day practical training standard teaches the principles and practices of laser scanning for use in construction specific contexts and covers the practical elements, relevant theory, use of software and considerations when working in a public area.
