Construction: Change Order Audit with Claude Code: Cost Controls
A production playbook for change order audit in construction operations using Claude Code: cost controls, run-scoped inputs, logs, typed results, and artifacts.
Audience: Construction finance and project controls teams
The problem
Construction finance and project controls teams need change order audit to run repeatedly against change orders, contracts, invoices, schedules, and field reports. In construction operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Set explicit limits for change order audit: input size, run time, tool calls, artifacts, retries, and concurrent runs per organization.
Tradeoffs and failure modes
Limits reject pathological runs, but they keep one workflow from turning into an unbounded infrastructure bill. For change order audit, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
