Hi all,
I was hoping someone could help explain this architect drawing I have received. It says EGL 77.7 PGL 77.80, does this mean the proposed ground level is 73cm higher that the existing ground level?

I am in the US, but one would assume that EGL means existing ground level and PGL means proposed ground level. Hear in the US we use decimal feet for elevation on site plans. Sometimes they are carried to the tenth and sometimes to the hundredth even on the same plan. It certainly looks like the difference is 1/10 of whatever unit of measure they use where you are.
