I was wondering if you guys have multipliers for high ceilings. I am bidding large residential shop with 16' ceilings and I am trying to figure how much time to add for all the extra steps up and down the ladder. I was thinking somewhere in the 10-15% range. Any thoughts?
There are time and motion units for ladder tasks, but they don't include your employees mood for the day, or job conditions, your best figures come from job actuals records, it may pay to look at scaffold or lift, there may be a savings, compared to moving ladders, and attempting to carry equipment, and material up a ladder.
LK is right on the money. Also factor this, on day #1 I work pretty fast off a 12 foot step ladder. On day #2 I start out slightly slower and by the end of the day am begining to feel it. On day #3 marked difference in speed. All this is negated however if the job runs 2 weeks or more in which case I get acclimated to the weight of moving that ladder around and it all becomes normal again. Make the job last 6 months or more and I can work that ladder like its a 4 footer.
Speaking of which... I've got some 20' ceilings and no clue how to safely work up there. How do you guys usually handle rooms that tall, 16' stepladder? What do the drywall people do? I was thinking about just biting the bullet and building staging out of 2x and plywood. This is just a cathedral ceiling in a residence, so no boom truck.

If the residential shop has a concrete floor the scissors lift is a great way to go. Add the rental & some non-productive time to the bid & have fun. I timed myself on a commercial job with identical tasks & the lift cut my time in half. It was a lot easier day with the lift also.
BobbyHo has it with the ladder. A 16' stepladder has a huge footprint. The legs may be 10' apart and it might weigh an awkward 200lbs. It's much more common to use scaffold, which you'll need a second guy to assemble.
