What will happen if the time is not taken to properly measure and lay out a job before
trying to bend conduit? - CORRECT ANSWER-I. Additional labor to re-bend
II. Conduit may need to be bent multiple times as a result of inaccurate measurements
IV. Increased amount of scrapped conduit
The only viable method to reduce the material cost itself is to reduce waste, and the
