Planning perspective
When requesting a quote for rooftop HVAC dunnage, provide the equipment make, model, weight, and manufacturer's cut sheet when available. Also provide the required support height, roof slope and structure information, and desired finish. Project requirements, including loads, clearances, attachments, and applicable codes, should be confirmed by the project's qualified professionals.
Define the rooftop unit and support condition
Dunnage pricing depends on more than the rooftop unit's overall weight. The project information should identify each support point, operating weight, required elevation, curb or rail relationship, service-clearance envelope, roof slope, and the structural members intended to receive the reactions. For replacement work, identify whether the new unit footprint differs from the existing support.
HVAC dunnage pricing checklist
- Current equipment schedule and manufacturer cut sheet
- Operating weight and support-point layout
- Required top-of-steel elevation and roof slope
- Roof framing plan and proposed load-transfer points
- Access, curb, flashing, and service-clearance constraints
Resolve before fabrication release
Confirm the final equipment model, orientation, support points, elevations, connection details, and who is responsible for roofing interfaces. A change in unit selection can change frame geometry and reactions, so approval should use current equipment data.
Information to assemble before requesting pricing
- Current drawings, sketches, dimensions, and clear site photographs
- Equipment manufacturer, model, operating weight, support points, and current cut sheets
- Design criteria, loads, connection requirements, and approvals from the responsible project professionals
- Material, finish, inspection, submittal, schedule, and delivery requirements
- A clear list of requested inclusions and work that will be performed by others
How USA Structural approaches quote review
USA Structural uses the available project information to determine whether a fabrication scope can be priced and what open items require clarification. Early information can support an initial review, but fabrication should proceed only from current, approved project information. Listing a planning consideration does not mean it is included in a quote.

Frequently asked questions
Can USA Structural price from incomplete information?
Available information can be reviewed, but missing dimensions, loads, specifications, or responsibilities may prevent firm pricing. Any assumptions and exclusions should be resolved before release.
Who is responsible for final design?
The project's responsible licensed professionals retain design and approval responsibility unless a written agreement explicitly establishes a different, appropriately licensed scope.
Are finish, freight, and installation included?
Not automatically. Each item must be requested and confirmed in the accepted quote. The reviewed evidence does not establish a general installation service or nationwide delivery promise.
