Calculations That Pass
Chicago requires Illinois-licensed structural engineers for roof decks, load-bearing modifications, and any work that deviates from prescriptive code paths. The city's 100 PSF live load requirement for rooftop spaces demands calculations that prove your structure can handle people, furniture, and whatever else you place up there—calculations that must be stamped before permits are issued.
Our structural engineering covers the full scope of residential and commercial analysis: beam sizing and connection design, column load paths, foundation capacity verification, wind and snow load calculations per Chicago Building Code Chapter 16. We prepare stamped drawings that satisfy Department of Buildings plan review on the first submission, eliminating costly revision cycles.
The advantage of in-house engineering is speed and coordination. When structural analysis happens alongside architectural design, conflicts get resolved on paper rather than in the field. Your permit package moves through review faster because engineering and architecture speak the same language from day one.
