Site-specific evaluations.
When an opening falls outside the approved size limits, we analyze the product at the required dimensions and seal the result.
Design pressures calculated per ASCE 7 for your address, exposure, height, and zone, then verified against the product's rated capacity.
Substrates, edge distances, and existing conditions that do not match the tested anchorage get a designed alternate with a fastener schedule.
Mullions, receptors, and reinforcement sized for deflection and pressure across multi-unit and storefront configurations.
Glass type, thickness, and lite makeup evaluated per ASTM E1300 for the design pressures at the installation.
Primary and secondary drainage, ponding checks, slope and scupper sizing, plus uplift and attachment analysis for roofing assemblies.
Missed inspections and after-the-fact fixes.
We evaluate the as-built condition, document what complies, and specify targeted remediation so the permit can be closed instead of reopened.
Field verification and engineering letters that give the building department a defensible basis to accept work that went in ahead of approval.
When the installed product is not the one on the approved plans, we evaluate the substitution and issue the documentation to reconcile it.
Signed and sealed letters for inspectors, insurers, lenders, and owners, written to answer the specific question being asked.
Product types we cover.
Single and multi-unit assemblies, impact and non-impact, new and replacement.
Entry, sliding glass, French, garage, and commercial storefront systems.
Skylights, roof assemblies, underlayment attachment, and drainage.
Shutters, railings, cladding, awnings, and exterior attachments.
That is a site-specific engineering evaluation. We analyze the product at the size and pressure your opening requires and issue sealed calculations and details that let the installation proceed.
Yes. When the substrate, edge distance, or existing conditions do not match the tested anchorage in the approval, we design an alternate attachment and document it for the building department.
Often, yes. We evaluate the as-built condition, document what meets code, specify remediation for what does not, and provide the engineering letter the inspector needs to close the permit.
We perform glass load calculations per ASTM E1300 and design mullions, receptors, and reinforcement for the design pressures at your site.
