Register for free to look up 10 items; or sign up for monthly use - $.99/first month, then $3.95/mo., cancel anytime.
The data search looks like the screenshots below.
The localized cost modifier seems to be a constant percent when I spot checked it. So you could do that just once on your subtotal.
The key features of cost estimating don’t require exact unit costs, which don’t exist anyway. Just look at the bids you receive for proof.
SUMMARY - PROs
Lots better than guessing
Low learning curve
SUMMARY - CONs
A little more time-consuming than I would like
Must transcribe costs, which is error-prone
