Change Management

How scope moves and money follows: change events, PCOs, CORs, owner and subcontract change orders, directives, claims, and backcharges.

10 objects documented in this department.

Foundation

  • Change Event CHG 101 · Foundation · Change Management
    The first, neutral record that something has deviated from the contract scope — the container that captures a potential change before anyone knows its cost, cause, or outcome.

Practitioner

  • Potential Change Order (PCO) CHG 201 · Practitioner · Change Management
    The priced, characterized proposal that a validated change event becomes — the contractor's estimate of what a change will cost and how it affects time, before the owner has agreed to anything.
  • Change Order Request (COR) CHG 202 · Practitioner · Change Management
    The formal, packaged request that asks the owner to execute a change to the contract — the priced PCO assembled with its backup and submitted as a contractual demand for authorization.
  • Owner Change Order (OCO) CHG 203 · Practitioner · Change Management
    The executed, bilateral amendment between owner and contractor that actually changes the contract price, time, or scope — the only document that formally makes a change part of the contract.
  • Subcontract Change Order (SCO) CHG 204 · Practitioner · Change Management
    The executed amendment between a general contractor and a subcontractor that adjusts the subcontract price, time, or scope — the flow-down that keeps the buy-out matched to the prime contract.
  • Backcharge CHG 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.
  • Allowance CHG 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.
  • Contingency CHG 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.

Advanced

  • Construction Change Directive (CCD) CHG 301 · Advanced · Change Management
    The owner's unilateral written order directing the contractor to proceed with a change before price and time are agreed — the instrument that keeps work moving when the parties cannot yet settle a change order.
  • Construction Claim CHG 302 · Advanced · Change Management
    The formal assertion of a right to additional compensation or time when a change request has been denied or a dispute cannot be resolved through the ordinary change process — entitlement, causation, and damages, packaged for adjudication.
