Background & Context

3 stories

2.1

The mechanics-lien clock starts before you think.

In most SD 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.

2.2

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.

2.3

When prevailing-wage rules apply to your project.

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.

Why It Matters

Wage-rate violations carry back-pay liability, debarment from future public bidding, and personal liability for officers in many states. The audits look back years.
