In this blog series “Answers from the Engineer”, our panel of fabric structure experts answers questions from industry insiders submitted during a recent webinar regarding fabric structures. Today’s questions address foundations.
Q. How do the foundation costs of fabric buildings compare to traditional pre-engineered metal buildings (PEMB)? Higher uplifts? Are lateral thrust forces due to rigid frame action the same as with traditional PEMB?
Yes, you will find that because we are using loads driven by ASCE7 for load determination that the horizontal, vertical and uplift vertical forces will be nearly identical in fabric building foundations to PEMB foundations.
Q. Are foundations typically larger for fabric buildings versus PEMB?
There is no real difference in magnitude. You will find that because we are using loads driven by ASCE7 for load determination that the horizontal, vertical and uplift vertical forces will be nearly identical.
Q. Can Legacy design a foundation?
Currently we provide about 50% of the foundations with our buildings. Many owners like to keep the whole design in one contract to streamline their permit process, turning in stamped foundation drawings with the stamped building drawings. Other clients have local engineers they use on projects, so we give them our preliminary reactions and work with the foundation engineer to make sure the anchor bolt layouts work with their foundation.
