What process do you guys have in place for payroll for actual versus estimated quantity’s of material used?
Estimator measures and orders for a job 20.66 Sq of field shingles, .66sq of hip/ridge using standard waste factors. Maybe you send a tad extra 21sq / 1sq out to job just in case of a shortage? How do you account for overages if crew reports they used more than the estimated amounts? Measuring and waste factors are not 100% accurate plus you have the potentials of crew stowing extras in trucks/dumpsters etc (theft).
Say… if the crew tear into a fresh bundle of ridge cap for just a couple extra Lf. How do you pay/account for this? .33 extra could really add up over a year.
