my first job, the head field super, takes my drawing and says 'this is what we do with your drawings in the field', and crumples it up and throws it in the garbage.
then i move states, get a job at a top notch company where they actually do real sprinkler work, and i throw it away to go to...
and then, what if the company doesn't care about the survey, and you go out when you're not supposed to, then they think you're stealing time, and you get fired? how does that work?
this is all assuming this is a real job, and not some type of government targeting operation.
don't the fitters just figure it out in the field?
if i have an estimator's drawing already, how much more can i really contribute by 'surveying' the existing system?
