Rooftop equipment anchorage engineering
Rooftop Equipment Anchorage Engineering
Structural evaluation and design of equipment attachments, considering applicable wind and seismic forces in plain language without presenting project-specific calculations or conclusions.
Who this service helps
- HVAC contractors securing rooftop equipment
- Architects specifying anchorage for new equipment
- Property managers in wind-exposed coastal areas
- Permit coordinators responding to anchorage comments
Common situations that lead to this request
- A permit requires anchorage to be evaluated for wind or seismic forces
- New equipment is being installed where anchorage did not exist
- A replacement changes the attachment arrangement
- Coastal exposure raises wind considerations
What the evaluation or design process involves
- 1Submit equipment details, location, and attachment arrangement.
- 2Ian's office reviews the applicable forces for the project.
- 3After authorization, the anchorage is evaluated or designed within the agreed scope.
- 4Findings and any needed attachment details are documented.
Documents needed to begin
- Equipment specifications and weights
- Proposed attachment arrangement
- Roof plans and existing drawings, if available
- Project location for wind/seismic considerations
Possible deliverables
Subject to agreed scope.
- Anchorage evaluation or design within the agreed scope
- Stamped calculations where required
- Attachment detail recommendations when needed
Factors affecting cost and scheduling
- Complexity of the attachment and forces involved
- Whether existing drawings are available
- Number of units
- Requested turnaround
Cost and turnaround depend on project review. No fixed price or guaranteed schedule is quoted before scope review.

Equipment Anchorage Evaluation — frequently asked
What wind and seismic considerations apply?
Rooftop equipment can be subject to wind uplift and seismic forces depending on location, height, and weight. The evaluation considers the applicable forces for your specific project.
Can you tell me if my equipment is safely anchored from a photo?
No. Anchorage depends on the specific attachment, substrate, and forces. Ian reviews the equipment and structural information before determining what is required.
