Question 1

How do I vet a design-build parking contractor?

Accepted Answer

Verify parking-specific project history (5+ completed projects), in-house technology integration capability, active licenses and adequate insurance ($2M+ GL), GMP capability, and climate-specific construction expertise.

Question 2

What is the difference between design-build and design-bid-build?

Accepted Answer

Design-build places design and construction under one contract. CII research (RS-133) shows DB projects are 12–33% faster and 6–12% cheaper than traditional design-bid-build delivery.

Question 3

How much does a design-build parking project cost?

Accepted Answer

A 100-space surface lot with technology integration costs $250,000–$600,000 under design-build, or $2,500–$6,000 per space including LPR, payment systems, lighting, and EV charger conduit.

Question 4

What licenses should a parking contractor have?

Accepted Answer

General contractor license, electrical contractor license, workers' comp, $2M+ general liability, and completed operations coverage. IPMI CPP certification indicates parking-specific expertise.

Question 5

How long does a design-build parking project take?

Accepted Answer

A 200-space surface lot takes approximately 21 weeks under design-build versus 36 weeks under traditional delivery — 42% schedule compression.

Question 6

What warranty should I expect?

Accepted Answer

Structural: 5–10 years. Paving: 2 years. Technology systems: 1–2 years workmanship plus manufacturer warranties. LPR accuracy guarantee >98%.
