Unexpected underground duct bank

A change order is not merely a price-and-days transaction. It is a governed resolution of a triggered risk allocation — and what it does not resolve stays visible.

ILLUSTRATIVE · SAMPLE DATA
A synthetic negotiation fixture, not the governed record. No figure here is filed, and none of it is aggregated with the filed instruments.

Risk resolution

The continuity chain, in order. No separate change-order risk framework.

A change order does not automatically close a risk. Remaining uncertainty stays on the record until an act closes it.

What the change order changed — object matrix

Scope, money, risk and schedule move together against the same objects. A change order that has been executed but not decomposed shows as a GAP, never as a balanced set of rows.

The claimed decomposition below totals $1,200,000. The governed change order CO-014 executed $740,000 and has not been decomposed across objects — that mapping is a GAP, not a pro-rata split.

A claimed decomposition and an executed change order are two separate figures. The difference is stated only where the change order was executed in settlement of the claim. The change order was executed in settlement of this claim.

Illustrative object graph. The object effect, the SOV effect, the risk effect and the schedule effect are four separate columns because they are four separate facts.
