This Letter of Design Certification ensures that the materials furnished by the metal building supplier will be designed
in accordance with the information specified to the metal building supplier on the order documents and summarized
by the loading information listed below. The Project Engineer of Record (not the metal building supplier) is
responsible for verifying that the building code and design loads meet any and all applicable local requirements.
The Professional Engineer whose seal appears on this Letter of Certification is employed by the metal building manufacturer
and does not serve as or represent the Engineer of Record for this project and shall not be construed as such.
