Background & Context

3 stories

3.1

Why a foundation problem is almost always a soils-report problem.

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.

Why It Matters

Foundation remediation costs typically exceed the original foundation cost by 5-10x. Investing in current, footprint-specific geotechnical work is the cheapest insurance a project carries.

3.2

Pay-when-paid versus pay-if-paid — the one-word difference.

"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. Many states will not enforce pay-if-paid clauses without unmistakably clear language; ambiguity defaults to pay-when-paid.

Why It Matters

The risk allocation between subcontractors and GCs hinges on this one phrase. Subs who sign pay-if-paid contracts effectively underwrite owner credit risk on top of project risk.

3.3

Substantial completion is a legal status, not a percent.

"Substantial completion" is achieved when the owner can occupy the project for its intended use — not when a punch list is finished or a percentage is hit. The status starts warranty clocks, transfers risk of loss, and triggers retention release in most contracts. Disputes over whether SC has been achieved are common at month-end.

Why It Matters

Premature certification of substantial completion commits the contractor to warranty coverage on incomplete work; delayed certification gives the owner leverage to extend retention. The legal definition controls, not the status meeting.
