Mortenson met the tight schedule, thanks to the off-site strategy. And while the off-site work boosted productivity, it cost 6% more. Gregor attributes that to the fear factor in the bids of subcontractors, unaccustomed to off-site work. He expects prices to come down once subcontractors gain a comfort level that comes with experience.
