[MW:15429] Reg Verticality

Dear All Experts
 
We are manufacturing flue gas duct piping for boiler chimni of 4* 360 MW, I have that confusion in one point that how to check the verticality of shell(of Dia 5m & one shell containng two segment of 2.5m height i.e. one shell of 5m height), now pls clarify that is it right to check the verticality of the shell at fabrication stage(of 5m height shell) bcoz we have no flat ground available to check verticality or On the other hand if the total height of flue gas duct piping is 275m then we can check the verticality of shell at erection stage bcoz at erection stage we will have flat ground.
 
Pls clarify
 
WIth regards
