Background & Context

3 stories

3.1

The change-order trap that erases written contract terms.

Most construction contracts require change orders to be in writing, but many states enforce an "oral modification" exception when the parties' conduct shows agreement — especially when the changed work is performed and accepted without protest. Continued performance without written change orders can waive the writing requirement entirely.

Why It Matters

Contractors who do extra work hoping to "true it up later" routinely lose those claims because the conduct shows acceptance of the original scope. A signed change order before the work is the cleanest evidence of agreement.

3.2

The mechanics-lien clock starts before you think.

In most IL jurisdictions, the lien filing deadline runs from last day on the project OR last delivery of materials, whichever is later — but several states use a project-wide cutoff (substantial completion) regardless of when your specific work ended. Counting the wrong start date is the leading cause of waived liens.

Why It Matters

A blown lien deadline drops your collateral down to a personal-guaranty claim, which often means recovery cents on the dollar. The window is short — 60 to 120 days in most states.

3.3

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.
