DCMA Non-Conformance Summary
32% of activities have non-ASAP constraints — 6.4× the DCMA 5% threshold. Of the 48 hard constraints, 32 (67%) have no approved justification on file. This represents a significant audit risk ahead of the Owner's Q2 2026 schedule review. MFO constraints on STN.030 and COM.005 are particularly problematic as they override network logic.
Remediation Action Plan
Priority actions for DCMA compliance:
- Review and remove 32 unapproved constraints by 15 Mar 2026
- Replace MFO constraints with milestone activities where possible
- Document contractor constraint justifications in Schedule Basis memo
- Target ≤ 10% by next audit (Apr 2026)
