Zaha Hadid is suggesting “design adjustments” to bring down the cost of the proposed Collins Park Parking Garage.
Miami Beach commissioners asked Zaha for a redesign of the garage earlier this year, after a consultant said that it would cost $49 million for construction. The initial budget for construction was $20.8 million.
Last week, commissioners were shown changes that could bring the construction cost of the garage down to $28 million. The new design would cost about $58,000 per space for 460 spaces planned in the garage (a price including retail and plaza space), while city staff claimed that a “regular” garage would cost about $20,000 per space to build.
Mayor Phillip Levine still wasn’t satisfied however, saying that he wanted it built “as cheaply as possible,” which he said should be “closer to $25 million.”
City staff will provide commissioners with an updated construction estimate within months.
ZHA’s design adjustments implemented to find cost reductions:
- Curves optimized – all radii the same
- Vertical Columns
- Grid / Column layout regularized
- 40′-0”spans reduced to 36’-0”
- Slab thickness reduced to 12”
- Cores redesigned to be as simple and efficient as possible
- One 27’ bay eliminated for the 3 ”flyover” levels this eliminates 4 columns and a 27’-0”portion of slab over three levels
- Balustrades greatly simplified to be a simple vertical balustrade alternates in-situ and steel guardrail system, requiring no elaborate formwork
- Roof Pavilions eliminated
- Feature Stair and glass elevator eliminated replaced with simple switch-back stair within structural concrete enclosure
- Landscape design eliminated surface treatment only
- Retail Area potentially reduced to Retail A only. Please price Retail B, and C optional and priced separately
- Vertical Retail Facade
