Dnk,
They have no problem, because they know the costs involved, the company he works for has been in the construction business, since the 30's, and they have a large staff in the estimating group, it's the way they plan jobs that has allowed them to profit all these years, it appears that equipment sales is part of their earnings.
I thought it was intresting, how the larger companies, track their costs to maintain profits, what i learned from this is there in no magic mark-up number to use, but by assigning the proper cost burden to material can help maintain profits.
