The Westlake Hialeah retrofit is an HVHZ glazing retrofit project in Hialeah, Miami-Dade County, Florida — one of the most technically demanding glazing project types in the Florida market. Retrofitting an existing building to HVHZ compliance means removing existing non-impact or non-compliant glazing and replacing it with systems carrying current Miami-Dade NOAs, sized and anchored to the building's existing structural conditions. ACG provided the complete HVHZ-compliant replacement glazing package — new impact-rated systems with TAS 201/202/203 documentation, design pressure analysis, and anchorage details for the existing substrate conditions at the Hialeah site.

Glazing retrofits in HVHZ — replacing existing non-impact or non-NOA-documented glazing with fully compliant HVHZ systems — are among the most complex and technically demanding glazing project types in the Florida market. Unlike new construction, where the designer controls the structural conditions the glazing is anchored to, a retrofit must work with the existing building's substrate, frame rough openings, and structural elements as built. The retrofit contractor must evaluate the existing conditions and select replacement systems whose NOA anchorage requirements can be satisfied by the existing substrate.
The Westlake Hialeah project is an HVHZ glazing retrofit at a commercial property in Hialeah, Miami-Dade County. Every glazed opening in the scope was evaluated for rough opening dimensions, substrate material, and structural conditions at the anchorage locations. ACG selected replacement glazing systems with Miami-Dade NOAs appropriate for the existing structural conditions — systems whose NOA anchorage requirements were achievable in the existing concrete, CMU, or steel structure without requiring significant structural modifications.
The demolition of existing non-impact glazing in an occupied or partially occupied building requires specific safety protocols: temporary protection of the opening during the window between removal and installation, debris containment to prevent glass fragments from entering the occupied space, and coordination of work sequence to minimize the time each opening is unprotected. ACG managed the demolition, temporary protection, and installation sequence for the Westlake Hialeah retrofit to minimize risk to the building's occupants during the work period.
Miami-Dade HVHZ permit documentation for a retrofit project includes: the existing building's structural information, proof that the replacement system's NOA anchorage requirements can be met by the existing substrate, the current NOA with a design pressure rating covering the building's calculated wind load at each opening, and a full shop drawing set showing the replacement installation in the existing rough openings. ACG prepared this complete retrofit submittal package for the Hialeah permit.
Technical highlights of the Westlake Hialeah HVHZ retrofit scope:
HVHZ glazing retrofits in occupied or partially occupied commercial buildings require careful scheduling to minimize disruption to building occupants. Each glazing opening represents a temporary weather and security exposure during the demolition-to-installation window; ACG planned the Westlake Hialeah retrofit work sequence to minimize this window at each opening and to prioritize occupied or critical spaces for accelerated turnaround.
Miami-Dade HVHZ permit review is thorough — the building department examines NOA documentation, substrate conditions, and anchorage details carefully on retrofit projects, where the interaction between the new system and the existing structure can produce conditions not present in new construction. ACG submitted early and responded to plan review comments to maintain the project's permitting timeline.
Hialeah is a dense urban environment; material delivery and staging at the retrofit site required coordination with the building's parking, loading access, and security. ACG pre-planned the delivery logistics for each phase of the retrofit work.
An HVHZ glazing retrofit is the replacement of existing non-impact or non-compliant glazing in a building located in Miami-Dade or Broward County with systems carrying current Miami-Dade NOAs. Retrofits differ from new construction because the replacement system must fit the existing rough openings and its NOA anchorage requirements must be achievable in the existing structural substrate. ACG manages the full technical process: existing condition assessment, system selection, NOA documentation, and Miami-Dade permit submittal.
Hialeah is in Miami-Dade County, and all of Miami-Dade County is HVHZ under the Florida Building Code. All exterior glazed openings in commercial buildings must carry current Miami-Dade NOA documentation. Buildings constructed before HVHZ requirements were strengthened, or buildings where non-compliant glazing was installed, may need a retrofit to achieve full HVHZ compliance.
When a commercial building owner or operator discovers non-compliant glazing in an HVHZ jurisdiction, the typical path is to engage a licensed contractor to provide replacement systems with current Miami-Dade NOAs and to permit the replacement work with Miami-Dade Building and Zoning. The permit submittal must include the current NOA for the replacement system, design pressure analysis, and anchorage details demonstrating compatibility with the existing substrate.
Yes. Replacement glazing in HVHZ must carry Miami-Dade NOAs documenting TAS 201, 202, and 203 test compliance — the same requirement that applies to new construction. A retrofit does not allow installation of non-TAS-tested systems just because the building was built before HVHZ standards were adopted.
In most cases, yes — concrete and CMU substrates are commonly used for HVHZ glazing anchor points. The NOA specifies minimum concrete compressive strength (f'c), minimum fastener edge distance, fastener spacing, and fastener type. ACG evaluates the existing substrate against these requirements for each opening and provides supplemental anchorage or substrate repair where the existing conditions do not meet the NOA requirements.
Yes. American Commercial Glass (FL CGC #1531993) performs HVHZ glazing retrofit work in Miami-Dade County, including Hialeah, Miami, Coral Gables, and other Miami-Dade jurisdictions. HVHZ retrofit work requires specific expertise in existing condition assessment, NOA system matching, and Miami-Dade Building Department submittal requirements that ACG has developed across multiple Miami-Dade retrofit projects.
A Miami-Dade HVHZ glazing retrofit permit requires submission of: current NOA for the replacement system, design pressure analysis confirming DP coverage, shop drawings showing the replacement installation at each opening, documentation of the existing substrate conditions, and anchorage details. Miami-Dade Building and Zoning reviews the submittal for NOA validity, system size within the tested envelope, and anchorage compliance before issuing the permit.
Yes. Hialeah is in Miami-Dade County, and all of Miami-Dade County is designated HVHZ under the Florida Building Code Section 1609.1.1. Every exterior glazed opening in commercial buildings in Hialeah must carry a current Miami-Dade NOA.
