Why Do Construction Bids Vary So Much From the Same Set of Drawings?
I recently sent the same blueprint set to a few contractors and was surprised at how different the numbers came back. The scope looked identical to me, yet labor assumptions, material takeoffs, and allowances seemed all over the place.
It made me wonder how much comes down to how thoroughly the plans are reviewed in the first place. Getting reliable blueprint estimating services sounds like a smart move when you want a clear baseline before comparing quotes or negotiating changes.
For contractors and homeowners here, what usually causes the biggest gaps between bids? Missing details in the drawings, different construction methods, or just conservative vs aggressive pricing?
