Laser Levels & Datums Explained – How to set up a laser level for Groundworks using the UK Datum

In this weeks video I explain where and how levels in construction originate from and in particular how the Ordnance Datum Newlyn is transferred to sites and used all across the construction industry. I find using this method of adding the height of your own rotary laser to the transferred datum far easier than manually using a tape measure. Thanks for watching and as always I appreciate any feedback offered to improve. Ben :)
