DESCRIPTION OF PROJECT
The 'Greenview Cleaners-HVAC' project consists of the replacement of an HVAC roof top unit (RTU). The unit will sit on
an existing curb. The scope of this calculation evaluates the existing structural (purlin) members for the additional loading,
as well as the attachment of the new units to resist wind and seismic forces.
