6. A Structural Group Company PRELIMINARY REPORT & RANKINGS • Survey documentation • Order of magnitude repair investment • Proposal(s) • Full condition assessment • Repairs Plant Condition Management System (PCMS) Process – Preliminary Report
7. A Structural Group Company Plant Condition Management System (PCMS) Process – Preliminary Report
8. A Structural Group Company Plant Condition Management System (PCMS) Process – Preliminary Report 1 2 3 Safety Risk & Diminished Structural Integrity Performance Risk Long-Term Durability Issues
9. A Structural Group Company PRELIMINARY REPORT & RANKINGS • Survey documentation • Order of magnitude repair investment • Proposal(s) • Full condition assessment • Repairs Plant Condition Management System (PCMS) Process – Preliminary Report  General findings  Quantify number of units found satisfactory  Locate & identify diminished structural integrity & falling concrete material hazards (i.e. safety) at reviewed structures  Locate & identify examples of deterioration of materials-of-construction related to diminished serviceability/durability (i.e., reinforced concrete, structural steel, fireproofing, etc.)  Recommendations  Repair priorities  Course of action  Conceptual repair strategies  Order of magnitude repair costs
