Services
Wind engineering for your project.
Standard packages have published prices. Custom work receives a written proposal; "typically" is the range those proposals have landed in. Every calculation is site-specific, under ASCE 7-22 and the code your jurisdiction adopts.
Components & cladding
The letter the permit office asks for when the product approval alone does not prove the installation works at your address.
- from $399
Doors & windows
Site-specific design pressures for every opening by zone and size, checked against the NOA or Florida Product Approval.
- from $459
Roofing
Uplift by roof zone, RAS 127 tile moments where the roof is tile, and the HVHZ roofing forms.
- from $499
Solar
Roof-mounted PV uplift by zone, attachment spacing and the racking check; ground mounts and solar poles quoted.
- from $249
Components & equipment
Rooftop units, condensers, generators, fences, signs, pergolas and canopies: lateral, uplift, overturning and anchorage.
- typically $1,900–$2,000
Site-specific installation drawings
When the permit set needs the attachment detail and fastener schedule on a sealed sheet, not just a letter.
Poles & pole-mounted equipment
Cameras, lights, antennas and solar fixtures add wind area to a pole. We total it, check the pole and the base, and write it for the pole owner or the AHJ.
- from $450
Light pole engineering
EPA summaries for everything on the pole, lateral force and moment, pole capacity coordination and the foundation check.
- from $450
Camera & ALPR poles
Permit-ready packages for new camera poles, their foundations, and attachments to existing street lights. Per-site pricing for rollouts.
Field testing & research
Some things an engineer has to see. What we learned at full scale feeds every pole, solar and equipment letter we write.
- Case study
150+ mph wind testing at FIU’s Wall of Wind
A solar fixture and light pole assembly in a simulated Category 4–5 wind field: where it moved, where it failed, and why the panel went before the pole.
- Quoted per project
Finite element modeling
When a hand calculation is not enough: slender poles, eccentric fixtures and connection-governed assemblies, modeled under ASCE 7 loads with the assumptions stated.
