The guard will be constructed so as to prevent the passage of a 21 inch diameter sphere. Guards will be constructed to resist a load of 50 pounds per linear foot applied in any direction at the top and to transfer this load through the supports to the building structure. The guard will also be designed to resist a 200 pound concentrated load applied in any direction at the top and to transfer this load through the supports to the building structure.

The packaged rooftop HVAC unit was installed without the outdoor air intake kits typically installed on them. This decreases indoor air quality in this highly occupied building. This is in violation of the building code. Furthermore, it does not provide make-up air to equipment such as shower/restroom exhaust fans, and clothes dryers that are required to exhaust air to the outdoors. (IMC, 2018, 403.2)

Indoor air quality is poor because of a lack of adequate ventilation. Natural ventilation is not introducing sufficient outdoor air because the building is very tightly constructed and it is not practical to open the windows during extreme conditions. The building's mechanical ventilation is not operational. (IMC 2018, 403.2)

Retain a licensed HVAC design-build consultant to calculate the building outdoor air requirement and provide outdoor air to the return air plenum by making the outdoor air fan functional. Rebalance the fan to provide the required code approved outdoor air to the building.

The packaged rooftop HVAC units ware installed without the typically included outdoor air intake kits. This condition decreases indoor air quality in this frequently occupied building which is a violation of the building code. Furthermore, the units do not provide make-up air to standard equipment pieces such as shower/restroom exhaust fans, and clothes dryers that are required to exhaust air to the outdoors.
