GC + Sub = Wind Load Success

When general contractors and window/door subs do not share wind load requirements, permits fail. Learn how to coordinate for HVHZ compliance.

The Coordination Workflow

GC Orders Wind Load Calculations

Before getting quotes from window/door subs, the GC gets wind load calculations for the project. This establishes the design pressures every product must meet.

GC Responsibility

Share Pressures with Sub

Include the wind load report when requesting sub quotes. Specify that products must meet or exceed the calculated pressures. Require HVHZ-rated products with valid NOAs.

GC Sends to Sub

Sub Selects Compliant Products

The sub chooses products rated for the specified pressures. Each product must have an NOA showing it meets or exceeds the design requirements.

Sub Responsibility

Sub Submits Product Package

The sub provides product cut sheets, NOA documents, and pressure ratings. The GC verifies each product meets the calculated requirements before approval.

Sub Sends to GC

GC Verifies and Submits Permit

The GC confirms product ratings match or exceed design pressures. Wind loads plus product NOAs go into the permit package. Everything is documented and coordinated.

Coordination FAQs

Who is responsible for wind load calculations? +

The general contractor typically orders wind load calculations as part of the permit package. However, window and door subcontractors must select products that meet the calculated pressures. Both parties share responsibility for compliance.

How do I share requirements with subcontractors? +

Provide subcontractors with wind load calculations before they quote. Include design pressures for each opening size. Specify that products must meet or exceed calculated pressures. Require NOA documentation in their submittal package.

What if the sub orders wrong products? +

Products with insufficient wind ratings will fail permit review or inspection. The sub must replace them at their cost if they deviated from specifications. Clear communication upfront about pressure requirements prevents this costly mistake.

Should wind loads be in the subcontract? +

Yes, always include wind load requirements in subcontract agreements. Specify the design pressures, require HVHZ-rated products with valid NOAs, and make the sub responsible for product compliance. This protects both parties from disputes.
