Decision Readiness
Ready with Restrictions

Evidence requirements are 4/5 satisfied. The unresolved verifier assignment and a separate pending structural recalculation constrain use without blocking procurement preparation.

Procurement Decision Support

Verified engineering data and condition assessments support procurement teams in evaluating reuse opportunities and preparing tender documentation.

Components in this case have been selected based on technical fit, verification status, and circularity potential. Digital Product Passports provide traceability and verification references that can support tender requirements.
