Parking structure construction remains a steady market segment driven by urban development, airport expansion, healthcare facilities, and mixed-use developments. While EV adoption is changing design requirements, the fundamental need for structured parking continues to grow.
Municipal/Government
Cities, counties, transit authorities, airports, and public universities. Usually lowest-bid procurement with prevailing wages.
Healthcare/Institutional
Hospitals, medical centers, and universities. Often negotiated contracts with phased construction around operations.
Private Development
Mixed-use developers, REITs, and parking operators. Focus on speed and aesthetics with value engineering.
Parking Structure Types
Advantages
- • Faster construction (30-50% faster)
- • Factory-controlled quality
- • Reduced on-site labor
- • Year-round construction capability
- • Long span designs possible
Considerations
- • Higher material cost
- • Transportation limitations
- • Joint waterproofing critical
- • Requires skilled erection crew
- • Limited site customization
Advantages
- • Design flexibility
- • Monolithic construction (fewer joints)
- • Local material sourcing
- • Easier to accommodate changes
- • Lower transportation costs
Considerations
- • Longer construction schedule
- • Weather dependent
- • More on-site labor required
- • Formwork costs significant
- • Quality control more challenging
Advantages
- • Longer spans (60+ feet)
- • Thinner slabs (more headroom)
- • Reduced cracking
- • More efficient steel usage
- • Better waterproofing potential
Considerations
- • Specialized labor required
- • Higher initial cost
- • Careful tendon layout required
- • Grouting quality critical
- • Future modifications limited
Advantages
- • Fastest erection time
- • Long clear spans possible
- • Lightweight structure
- • Easy future expansion
- • Good for poor soil conditions
Considerations
- • Fire protection required
- • Corrosion concerns
- • Higher material costs
- • Deck topping still needed
- • Less common in parking
Critical Building Systems
Waterproofing is the most critical system for parking structure longevity. Chloride intrusion from deicing salts is the primary cause of structural deterioration.
Traffic-Bearing Membranes
- • Polyurethane traffic coatings
- • Epoxy overlays
- • MMA (Methyl Methacrylate)
- • 10-15 year lifespan typical
Below-Slab Protection
- • Sheet membrane systems
- • Bentonite panels
- • Spray-applied membranes
- • Drainage boards
Joint Types
- • Armored expansion joints
- • Strip seal systems
- • Compression seals
- • Pourable sealants
Critical Locations
- • Deck-to-wall transitions
- • Precast panel joints
- • Column penetrations
- • Stair/elevator interfaces
Maintenance
- • Annual inspections
- • 5-7 year replacement cycle
- • Critical for structure life
- • Major warranty item
Lighting Requirements
- • LED fixtures (energy code compliance)
- • Daylight harvesting controls
- • Emergency egress lighting
- • CPTED security considerations
- • Typical 5-10 fc at parking level
EV Infrastructure
- • Level 2 charging stations (7-22 kW)
- • DC fast chargers (50-350 kW)
- • Electrical capacity for future expansion
- • Load management systems
- • Conduit for future buildout
Finding Parking Structure Projects
Municipal Projects
City/county purchasing portals, state procurement sites, and parking authority RFPs. Often require prequalification and bonding.
Airport Authorities
FAA-funded projects through airport websites. DBE participation often required. Long procurement cycles.
Healthcare Systems
Hospital construction managers and development teams. Often design-build or CM at Risk delivery.
Private Developers
Commercial real estate developers, parking operators like LAZ and SP+, and mixed-use project GCs.
Specialty Subcontractor Opportunities
High-Value Scopes
- • Structural concrete
- • Precast erection
- • Post-tensioning
- • Waterproofing/coatings
- • Expansion joints
Specialty Systems
- • Parking equipment (gates, PARCS)
- • EV charging installation
- • LED lighting
- • Security/CCTV
- • Elevator/vertical circulation
Winning Bidding Strategies
| Component | % of Total | Key Variables |
|---|---|---|
| Structural System | 45-55% | Precast vs CIP, spans, soil conditions |
| Foundations | 10-15% | Soil conditions, depth to bearing |
| Facade/Enclosure | 8-12% | Open vs enclosed, architectural requirements |
| MEP Systems | 10-15% | Ventilation, fire protection, EV infrastructure |
| Waterproofing | 5-8% | System type, climate, warranty requirements |
Schedule Acceleration
Offer accelerated schedules with precast or hybrid systems. Time is money for developers losing parking revenue.
Lifecycle Cost Analysis
Present total cost of ownership including maintenance. Better waterproofing systems save money long-term.
Extended Warranties
Offer extended warranties on critical systems like waterproofing. Demonstrates confidence in quality.
EV-Ready Infrastructure
Include EV infrastructure provisions even if not specified. Forward-thinking approach impresses owners.
Best Practices for Success
Concrete Quality Control
Specify low permeability concrete, proper curing, and adequate cover over reinforcement. Document with testing.
Waterproofing Installation
Manufacturer supervision during installation. Flood testing before acceptance. Document surface preparation.
Joint Detailing
Proper joint layout, sealant installation, and expansion joint detailing are critical for long-term performance.
- Inadequate drainage slope (minimum 1.5% recommended)
- Poor cold weather concrete placement practices
- Insufficient cure time before waterproofing application
- Improper joint layout causing premature cracking
- Underestimating electrical capacity for future EV charging
