Dwg terrain importing

[Mr_X]

Hello guys, im new on this forum. 

Today I've recieved from Geodesist dwg file from terrain. In this file i see this points with numbers of height but when i look this terrain from the sides it is flat terrain but its not (its 1-2m difference) , of course when i import from autocad the terrain is flat. Is it maybe this failure from geodesist or? 

Thank you. Greetings.
