Two ways to get sealed plans
Every ordered project is reviewed and sealed by a licensed Professional Engineer. The only difference is speed: qualifying signs run the 24-hour SignCalc track, and anything else is a quick custom proposal.
Qualifying signs
Standard pylons and monuments inside these limits get an instant estimate, a streamlined order, and a PE-sealed package back in 24 hours.

Real ASCE 7 provisions and your sign’s actual geometry, so every member is sized right, not over-built.

Actual-shape wind
Force coefficient pulled from ASCE 7 Fig. 29.3-1 by your sign’s real proportions, not a flat assumption.
Right-sized, not over-built
Accurate loads mean the correct pole and footing, less steel, still fully compliant.
Submittable package
Sealed calculations plus structural drawings, the full set a plan reviewer expects.
24-hour turnaround
Qualifying signs come back in a day, not weeks.
Pylon & monument
One or two poles, top-mounted cabinets and monument bases.
Free to estimate
Run unlimited preliminary estimates. Pay only for the sealed package.
