Structural Restoration in
Miami Beach.

Questions from Miami Beach boards and owners.

Is my Miami Beach building subject to Florida's SB 4-D milestone inspection?

If your building is a condominium or cooperative three stories or higher and was completed 25 or more years ago, yes. Florida Statute § 553.899 requires milestone inspection at 25 years for any building within three miles of the coast — and every building in Miami Beach is within that threshold. Reinspection is required every ten years thereafter. The inspection itself is performed by a Florida-licensed Professional Engineer or Architect; any structural deficiencies must be repaired by a qualified contractor before sign-off.

Why does the 25-year trigger apply across all of Miami Beach?

Miami Beach is a barrier-island municipality bounded by the Atlantic Ocean to the east and Biscayne Bay to the west. The entire city is within three miles of the Atlantic coast, which is the threshold SB 4-D uses to apply the accelerated 25-year milestone inspection rather than the standard 30-year trigger that applies elsewhere in Florida.

How does the Miami-Dade 40-Year Recertification ordinance overlap with SB 4-D in Miami Beach?

Both regimes apply. The Miami-Dade County 40-Year Recertification ordinance (Code § 8-11(f), enacted 1975) requires structural and electrical inspection at 40 years with reinspection every ten years. SB 4-D adds a parallel state milestone inspection at 25 years for coastal buildings, with its own ten-year reinspection cycle. Older Miami Beach buildings face both schedules. The repair scope that follows either inspection is similar — concrete restoration, post-tensioning, waterproofing, and structural reinforcement.

What's typical scope on a Miami Beach oceanfront condominium restoration?

Engineering reports on Miami Beach oceanfront buildings most often identify chloride-driven corrosion of reinforcing steel, concrete spalling at balcony edges and column bases, post-tension tendon failures in elevated slabs, and envelope leaks at windows, sliding doors, and parapet caps. The restoration scope typically combines concrete spall repair, rebar replacement, post-tensioning repair, balcony rebuilds, façade work, and re-waterproofing of the building envelope.

Do I need to hire an engineer before contacting CORE?

No. If your board already has a structural engineer engaged, CORE works directly with that team. If you haven't retained an engineer yet, CORE can connect you with its panel of partner engineers — licensed professionals who specialize in South Florida coastal restoration — so you have a single point of contact from first inquiry through final sign-off. Either way, CORE is the right first call.

Why is salt exposure especially relevant in Miami Beach?

Salt-laden air carried inland from the Atlantic accelerates chloride penetration into reinforced concrete, attacking embedded rebar and post-tension cables. Miami Beach buildings are exposed on every elevation — particularly oceanfront and bayfront — so chloride concentrations in concrete are typically higher than at comparable inland properties. The practical consequence is that a Miami Beach building of a given age usually shows more spalling, more rebar corrosion, and more PT tendon damage than an inland building of the same vintage.

Do you work on historic Art Deco buildings in South Beach?

Yes. Miami Beach's Art Deco, Mediterranean Revival, and MiMo (Miami Modern) districts include thousands of contributing structures, many of which require structural and envelope restoration while preserving original architectural features. CORE Builder Group works under the engineer of record and, where applicable, coordinates with the City of Miami Beach Historic Preservation Board on scope and methods consistent with historic-district guidelines.

How does Miami Beach permitting affect project timelines?

Restoration work in Miami Beach requires building permits issued by the City of Miami Beach Building Department, with structural review by city plans examiners. Permitting timelines vary by scope size and reviewer load — small balcony scopes can permit in weeks, while large recertification scopes take longer. CORE Builder Group prepares permit packages with the engineer of record at scope finalization to keep permit time off the critical path.

Can residents stay during restoration in a Miami Beach condominium?

In the majority of cases, yes. Restoration is sequenced floor-by-floor or stack-by-stack, with phased balcony access, dust containment, and where appropriate night-shift work to keep residents in place. Some scopes — for example a structural slab repair below an active unit — require temporary relocation; CORE works with the board to plan and communicate any unit-level disruption well ahead of the work.

What's the typical timeline for a Miami Beach restoration project?

A full structural restoration scope on an occupied Miami Beach mid-rise or high-rise typically runs 90 to 180 days from mobilization to final punch. Smaller scopes — a single balcony assembly, a stair-tower rebuild, a parking-deck section — finish in 30 to 60 days. The variables that most affect timeline are occupancy, access, scope depth once concrete is opened, and permitting.

Is post-tensioning common in Miami Beach buildings?

Yes. Post-tensioned slabs are common in Miami Beach mid-rises and high-rises completed from the 1970s onward, particularly in elevated parking decks and certain residential floor systems. Salt exposure accelerates corrosion of unbonded mono-strand tendons, which are the dominant PT system in Miami-Dade. CORE Builder Group is one of the few contractors in South Florida that self-performs post-tensioning repair with in-house trained crews — including emergency response for blown tendons.

Has CORE Builder Group worked in Miami Beach before?

Yes. CORE has worked on Miami Beach restoration projects including 1801 Purdy Avenue, and on adjacent oceanfront municipalities including Surfside (Parker Dorado, a 40-year recertification project) and other coastal buildings across Miami-Dade. The firm is licensed as a State of Florida Certified General Contractor and has been operating in South Florida structural restoration since 2013.
