Foundation failures rarely originate at the slab; they originate in soil bearing capacity, drainage, or expansive-clay behavior that was either uninvestigated or not honored in the design. A geotechnical report that is older than the building's design or that did not sample at the actual building footprint is a red flag.

Federal Davis-Bacon applies to projects with federal funding above a threshold; state "little Davis-Bacon" laws apply to state-funded projects with their own thresholds. The trap: rules apply to the work, not the contract — a privately funded portion of a project with any covered funding is subject to coverage on the whole.

"Pay-when-paid" sets a timing condition only — the GC must still pay even if the owner never does. "Pay-if-paid" creates a true condition precedent — no owner payment, no GC payment to subs.
