How to set up a level using a rotating laser. What is a level datum. How to calculate the height of collimation and set right level for construction works.
This is a first video from my SETTING OUT and surveying in construction series. At this will be your first duty on site today I am showing how the rotating laser works and how to use it. You will see how to set it using a tripod and what is the best way of setting it - make it as comfortable as possible and try to keep it in 'safe' place so no one moves it. PLEASE also remember don't set it just at 'the eyes' level - it's flashing and is not good for the eyes and it's annoying 😁 After starting a laser we will find a height of collimation having a known datum. Once we calculate it we can set whatever level we want and I am giving two examples when level is above height of collimation (eg. for decking) and one below (eg. dig level, drainage etc). As I found many people struggling with this, especially under stress on site below I have a simple exercise for you - don't forget to leave the comment!
👍👍👍 EXERCISE for you!!! 👍👍👍
Assuming our laser is spinning (height of collimation) 756mm above our 50500mm datum let me know what you have to set on the staff to get:
a) 60835mm
b) 47340mm
