Tire Repair Shop

[Kao Chen]

2006 IEBC is primary code. An existing tire repair shop (it was built pre-code for this area, 5B construction) is planning on adding a single story addtion of 2000 sq. ft. (2B construction) for three additional garage bays (no storage). Exisitng structure is 2 stories with a total fire area of 7782 sq. ft. (no separations vertically or horizontally). It contains 3332 sq. ft. of tire storage on the two floors (doesn't qualify as "high piled"). The IEBC for "additions" points to threshold limits of the 2006 IBC as governing sprinkler coverage (see Sec 903.2.8.1). Would you require a NFPA 13 system to be installed in the exisitng and the addition? Take a look at Sec. 903.2.8.2 '06 IBC.

Thanks for the input.

Unless there is a firewall the whole building is 5B........close to the 10,00 square feet and the 20,000cubic feet.....tough to say from here....if required, it would be the whole building....

Steveray is correct. You can't have a IIB addition on an existing VB building--either provide a fire wall to separate the IIB addition from the existing VB building (which solves your fire sprinkler issue) or consider the existing building and addition as a single VB building, which may or may not require a sprinkler system. As a Group S-1, you only need to sprinkler if the fire area exceeds 12,000 sf., but you may need it for an area increase since the maximum allowable area and height for a Group S-1 in a Type VB building is 9,000 sf and 1 story, respectively. You probably don't need it for area, but you'll need it for height in stories.

If an approved type fire sprinkler system is installed,

how long will it take for the decrease in insurance rates

to pay for the sprinkler system?

Be careful about sprinkler protection requirements for tire storage.

The height limit is 6 feet in the IFC for high piled storage provisions, but 5 feet in NFPA 13 for higher density sprinkler protection!

Question for the educated on high piled storage - a story with a mezzininie in it. The first floor and the mezzinine have tire storage - does this exceed the height limitations for high piled or is the magically 6 feet measured fromthe finished floor elevation?

I have always applied the 6 feet (as defined in the IFC) to the finished floor of the first story, The reasoning used is the that mezzinine is using the same atmosphere.

Thanks Ron....thats what I thought, but I didn't have access to Table 503....area would probably work with open perimeter....the # of stories would be problematic and it sounds too large to be a mezz...
