Look-Ahead ScheduleFLD 206 · Practitioner · Field Operations & Project Controls The short-interval, field-level plan — typically three to six weeks out — that translates the master CPM schedule into the specific, ready-to-build work the crews will actually execute.
Delay Notice & Time Impact AnalysisFLD 302 · Advanced · Field Operations & Project Controls The contractual notice that a delay has occurred and the schedule-based analysis that proves how much of the completion date it actually moved — the two instruments that establish or defeat an extension of time.
Site Photo DocumentationFLD 108 · Foundation · Field Operations & Project Controls The systematic capture of dated, located visual records of site conditions and work in place — the corroborating evidence that turns written claims about what was built into something you can see.

BackchargeCHG 205 · Practitioner · Change Management A cost one party incurs to correct or complete another party's work, then charges back against amounts owed to the responsible party — the mechanism for recovering the cost of someone else's default.
AllowanceCHG 206 · Practitioner · Change Management A defined sum carried in the contract for scope that is not yet fully specified — a placeholder that lets a project be priced and signed before every selection is made, reconciled against actual cost as the scope is defined.
ContingencyCHG 207 · Practitioner · Change Management A reserve of money set aside within a budget or contract to absorb the cost of risks that are anticipated in aggregate but not yet identified individually — the buffer between a project's estimate and its inevitable surprises.
