Pre-bid demolition intelligence · bridge remove-and-replace
Removal of the existing structure is ~1.5% of the winning bid — and the item bidders disagree on most in the whole proposal. Everyone prices the replacement well. Almost nobody prices the removal from evidence.

The asymmetry · measured, not folklore
The field · 13 states
Cross-bidder disagreement on demolition items runs 1.45–2.78× the level on everything else in the same lettings — highest where the item is an undescribed lump sum. Opacity is priced as risk.
The winners · 25,894 contracts
In every measurable state, winners carry the removal below their own bid average more often than not. The people taking the work price it like they know something. They do — they've done it before.
The envelope · where it hides
Winner lean on demolition runs 0 to −10%. On the temporary works around it — cofferdams, access, shoring — it runs 2–4× deeper. The mispriced money is the envelope, not the line.
