Good Evening Friends,
When setting stakes on uneven terrain and using a builders level or transit.

How do we know the mark on each stake is level?

Respectfully,

Check them with a water level.

[Robert WA]

Whatsa "transit"?????

[RETIRED]

Every day that my level goes on the tripod I check it as follows: set up level, shoot two levels a few metres apart that are at different heights, move level about 10 -20 metres over to the other side of the two check points, shoot levels again, make sure the difference between the two points is the same from both positions. That's my daily check, then every year (or more often if it's getting a lot of use) it goes in to get checked and calibrated. Plus you swear profusely :mad: at anyone that comes within two metres of the tripod and threaten to have anyone flogged :eek: if they touch the profiles. THAT'S how I know that all my marks are level!

I think a transit is what we call an engineer's level, like an automatic level but the head can be tilted in a vertical plane so as to transfer set outs up onto bulkheads and ceilings.

Whoops. Mick, you were not there when I posted.

my dictionary clearly states the same as ROBERTWA, with the one pivotal exception:

Good Morning Friends,
I got quite a kick out you fellows especially those who didn't know what a transit was. Actually it is nothing more than the engineers instrument that can traverse both horizontally or vertically.

The level has a line of sight that neither dips, sags, or curves and when setting grade stakes on uneven ground and establishing a grade line you are telling the dozer operator where to fill or cut to arrive to a rough level grade.

Her in Ohio I have seen the time when we had to lay a painters pick across a ditch to locate a stake with a grade mark on it for the operator.

Thank you all for your comments and support.

Respectfully,
