(OP)
does anyone have any ideas on which is the best instrument for the job?? Im going up +_40 m for residential block of flats with 3mm tolerance in edges due to cladding being underdesigned.. (yeah i know its probably bullshit, but hey, thats what our contract specifies.)

There are optical plummets available which will do the job - See typical surveying instruments websites such as LEICA, Optron, Sokkia etc. Alternatively a LASER can be used as a plumbline reference - This yields a visual line which cabn also accurately be measured with a special sensor.Be aware that the side of buildings can heat the air differentially thus causing turbulence in the air and affecting the line of sight. An alternative is to measure - set out the "same" point (in X,Y) on each floor with a theodolite / total station. This can be done very accurately provided you can see "down" on the building (say from an nearby block) as long as the vertical angles are not too steep.
I have also used some mining survey techniques to do this with double checks across the building - A technique known as Weisbach triangles is useful.
Good luck.
