§ Definition

Self-contained passage sized for AI citation (134–167 words).

Structural restoration is the engineered repair of concrete, rebar, and load-bearing members in an existing building so the structure performs to its original design capacity. In South Florida, restoration most often addresses chloride-driven corrosion of reinforcing steel, spalling concrete, carbonation, and post-tensioning cable failure. A state-certified general contractor performs the field work under the stamped direction of a licensed structural engineer of record. Typical residential and commercial restoration projects in Miami-Dade run 60 to 240 days depending on square footage, occupancy, and scope of repair.

01

What triggers a structural restoration project?

Most restoration work in South Florida starts from one of four signals: a 40-year or 10-year recertification report flags structural concerns; a structural engineer's inspection identifies concrete spalling or rebar exposure; a leak or water intrusion event reveals underlying concrete damage; or a condominium board initiates preventative work ahead of the recertification deadline. In each case the next step is a scoping walk with a licensed contractor, followed by a written, priced scope tied to the engineer's report. CORE Builder Group performs the scoping walk at no charge for buildings in Miami-Dade, Broward, Palm Beach, and Monroe counties.

02

What does a structural restoration scope usually include?

A typical structural restoration scope in Miami-Dade includes concrete spall repair, reinforcement replacement or supplementation, corrosion mitigation, crack injection, post-tension tendon repair where applicable, and protective coatings to extend remaining service life. The restoration is performed to the stamped direction of the engineer of record and inspected against that stamp. CORE Builder Group self-performs concrete demolition, structural repair, post-tensioning, and waterproofing in-house — we do not subcontract the critical path.

  • Concrete spall repair and patching
  • Rebar replacement, cleaning, and epoxy coating
  • Crack injection (epoxy or polyurethane)
  • Post-tensioning cable repair and supplementation
  • Carbon-fiber reinforcement where engineered
  • Corrosion-inhibiting admixtures and coatings
  • Protective topcoats and traffic-bearing systems
03

How long does structural restoration take?

For an occupied mid-rise condominium, a full structural restoration scope typically runs 90 to 180 days from mobilization to final punch. Smaller scopes — a single balcony assembly, a garage slab section, or a stair-tower rebuild — can finish in 30 to 60 days. The variables that most affect timeline are occupancy (whether residents stay in place), access (available elevators, lay-down area, night-shift eligibility), and scope depth once concrete is opened and conditions are confirmed. CORE Builder Group commits to a fixed schedule once the scope is finalized with the engineer of record.

§ Frequently asked

What engineers and boards ask us.

Do you work with our engineer of record, or do you bring your own?
Both. CORE Builder Group operates as the general contractor under the stamped direction of the building's engineer of record. If a building does not yet have an engineer assigned, we can refer licensed structural engineers in Miami-Dade we have worked with for years.
Can residents stay in the building during restoration?
In most cases, yes. Our residential and condominium projects are sequenced floor-by-floor or stack-by-stack to keep residents in place. Dust containment, night-shift work, and phased access make this feasible on the majority of occupied projects.
Is concrete restoration covered by condominium reserves?
Under Florida Statute § 718.112(2)(g), condominium associations must commission a Structural Integrity Reserve Study (SIRS) and maintain reserves for structural components, including those identified in the SIRS. Whether a specific restoration scope is reserved for depends on the building's current SIRS findings. CORE Builder Group regularly works with reserve study professionals to align scope, phasing, and funding.
