  8. 8. Parking Structure Maintenance Parking Structures • Not Bullet Proof • No Protective Skin • Deterioration Starts Immediately • Subjected To: • Moisture (Rain, Snow, Ice, Deicing Salts) • CO2 Carbonation • Extreme Thermal Expansion & Contraction • Dynamic Vehicle Loads
  9. 9. Parking Structure Maintenance Structure Degradation
  10. 10. Parking Structure Maintenance Structural Systems Cast-in-Place Concrete Precast Concrete Structural Steel
  11. 11. Parking Structure Maintenance Cast-in-Place • Advantages • Flexible Geometry • Monolithic, Fewer Joints • Reduced Maintenance Costs • Longer Life Expectancy • Higher Durability • Disadvantages • Higher Initial Investment • Longer Schedule • More Labor Intensive • Difficult Quality Control • Weather Dependent
  12. 12. Parking Structure Maintenance Precast Concrete • Advantages • Lower Initial Investment than CIP • Fabricated in Controlled Plant Environment • Not Weather Dependent • Accelerated Construction Schedule • Disadvantages • May be no local plant • Geometry not Flexible • Lower Perceived Ceiling heights • Shearwalls (Closed In) • More Joints • Prone to Thermal Expansion & Contraction Damage • Higher Maintenance Costs
  13. 13. Parking Structure Maintenance Structural Steel • Advantages • Lower Initial Cost than Precast • Accelerated Construction Schedule • Fabricated in Controlled Environment • No Shearwalls (Open) • Disadvantages • Corrosion Issues • Higher Maintenance Costs • Not Suitable for Fire Protection
  14. 14. Parking Structure Maintenance Typical Annual Life Cycle Costs $550 $467 $333 $167 $250 $447 $0 $100 $200 $300 $400 $500 $600 $700 $800 $900 CIP Precast Steel Cost/Space Maintenance Initial
