a. All loads and forces necessary to design the superstructure must be provided
by the structural designer of record. This must include all wind and seismic
b. The structural designer of record must review and approve all design
calculations and shop drawings.
c. A foundation design and anchor bolt design must be provided in the contract
documents. These designs will be evaluated based on the foundation

metal building manufacturer be sealed by a registered structural or civil
e. It shall be required that the metal building fabricator be certified through the
AISC Plant Quality Certification Program in the MB category.
f. All serviceability limit states that are to be applied to the superstructure must
be stated in the contract documents. The contract documents must state that
fixed base column design is prohibited.
g. Provide complete dimensions that include such information as roof slopes,
eave heights, floor elevations, required clearances, outside face of girts or
columns and any needed reference dimensions.
h. Indicate if the building is to be designed for future expansion and indicate
