Are there specific designs and/or requirements
with regards to basement level parking
having mechanized or automated parking lifts under the NFPA 101 and NFPA 13?
The 2009 NFPA 101, Section 184.108.40.206 for new hotels and dormitories and Section 220.127.116.11 for new apartment building, reference NFPA 88A, Standard for Parking Structures, and is applicable to assisted mechanical and automated type of parking structures. Chapter 6 of NFPA 88A has the requirements for fire protection.
Looking at NFPA 13 you will see no specialized requirements for the design and installation of the sprinkler system,
Because NFPA 88A and NFPA 13 do not clearly address the approach for sprinkler protection for thestorage configuration of automatic parking structures, an engineered solution is required
There is always more to add from the discovery of facts that change the parameters.
For high rise, let say 15 stacks enclosed mechanical parking building.
Is it necessary to install smoke exhaust system?
Thanks and Regards,
If the building safety regulation was referring to NFPA 88A, then an enclosed automated-type parking structure must have a continuous ventilation system that provide a minimum of two air changes per hour per Section 9.2.3.
Section 404 of the 2015 IMC and Section 406.6.2 of the 2015 IBC has the ventilation requirements for enclosed parking structures.
Section 403.4.7 of the 2015 IBC has the smoke removal requirements for high rise buildings.
Enclosed or underground parking garages require ventilation to remove harmful vehicle emissions and other pollutants, while providing fresh air. Ventilation is also a requirement in the event of a fire to remove smoke and to provide a clear access for firefighters. Exhaust and supply fans are used in conjunction with ductwork to distribute air throughout the parking garage, providing a common system for both pollution and smoke control.
Interesting thread given this use. Playing devil's advocate, I'd disagree with the application of parking garages is applicable. The automated part generally means the vehicle is palletized storage. You pull up to a garage, get out, and the system transports it. These systems have more in common with automated distribution type warehousing than parking garages. It is a pallet on a shelf. So the storage racks and robotics are equipment, and the vehicles are stored product. I would think from a code standpoint, it is a large open storage room like a warehouse. The racks and equipment aren't generally part of the building code anymore than a vehicle lift or service crane in a fleet maintenance facility.
If NFPA 88A was adopted by a local building safety regulation per my previous comments, then the automated-type is a parking structure.
I agree you may have a basis for an engineered solution for NFPA 13. A fire protection engineer may just buy into it.
NFPA 88A Standard for Parking Structures
Brief scope of standard:
This standard covers the construction and protection of, as well as the control of hazards in, open and enclosed parking structures, including automated-type parking structures, other than those within one and two family dwellings.
Thank you. Your response is a great help.
