The GC bid is a market signal, not a cost estimate.

Adjust market conditions: GC backlog, sub availability, material volatility. Watch the bid spread widen. A "cost estimate" is a GC's risk-adjusted price for absorbing uncertainty — not a calculation of what it actually costs to build.

The bid isn't what it costs. It's what it costs plus what the GC charges to absorb your risk. Hot market = wide premium. The GC isn't estimating — they're pricing.
