Commercial Repair Garages

Thanks for your input! I am in agreement with you both! No additional restroom

required in the Shop Area!

You might want to be real careful here. I'm pretty sure I can see a sex discrimination suit in your future. Why is it the women that need to travel 500' and not the men? Equal rights, etc.
 
Not true, it's still a unisex, just don't have to provide "separate" facilities.

If the ladies aren't of the mood to use a restroom visited by the male species, they can hike the up to 500 feet.
 
I believe the restroom requirements apply to the building, not to each separate portion of the building. Isn't the service/shop area and the waiting area all portions of the same building? If the shop area portion calculated out to 7 and the waiting area calculated out to 12, the total would still exceed 15 and the requirement for separate toilet rooms would kick in. I'm just throwing out numbers here, but the point is if the total number of occupants in the building necessitates two toilet rooms, then a toilet room for each sex is required.
 
I sent a request to the RDP for a "Code Analysis" of this project, ..no response

received yet! I am looking to see how he calculates the occ. loads for the

various [ different ] occ. types involved in each structure.

I will earnestly try to keep ya'll updated! ;)

Chapter 3 lists automotive showrooms in the business group. Table 1004.1.1 lists business areas as 100 sf gross per occupant. So that's the number I use for showrooms.

How is everyone calculating egress for the following areas?

Customer lounge - I've been figuring it as assembly w/o fixed seating.

Customer side of the parts counter - Business Area (100 sf gross)? Assembly (standing space at 5 sf net?) Lump it with whatever the adjacent area is?

Service Reception garage (where customers can drop off their cars for service) - I've used Industrial Area (100 sf gross) in the past, but think maybe I should start using Parking Garage (200 sf gross.)

He is risen indeed!
 
The customer waiting area is likely under 50 for Occ Load, so it is either a B or part of the main Occupancy. Beyond that, 'occupant load' is only 'needed' to calcualte exiting (and toilets...). The numbers associated with both of those requirements are such that a minimum sized door and unisex facility will likely suffice based on the building sizes in the OP. For the record, when calculating 'required facilities', the correct method is to calcualte each area by actual use, not by Occupancy Classification. (in other words, the customer lounge is 'used' for an assembly purpose, hence the fixtures are calcualted based on that, not the B occupancy classification for under 50 OL)

I have plans for a "new" auto dealership with 2 separate bldgs.One bldg. is the Sales / Showroom bldg. and the other is the repair

shop/garage.

What occupant load would I use for the Shop Areas ( referring to

Table 1004.1.1 in the 2006 IBC )?

The Gross Area of the Shop is 4,200 sq. ft., Type II-B, fully

sprinkled. Approx. 3,670 is actual Shop Area. Other accessory

spaces inside this same bldg. [ approx. 530 sq. ft ] include a

Waiting Area, with a transaction counter & customer waiting

area, 1 unisex restroom for the customers and 1 unisex for

the employees.

Thanks ya'll! :)

you could probably need some advice of the professional one's. ask some of the guys of the other Arizona auto repair shops, they seem to know the answer on your questions.
 
Section 304, B-Occupancy has Motor Vehicle Showrooms listed. Not an M-Occupancy.

Section 311, S-Occupancy for the repair area.

No clear allowance per occupant is listed

I have an architect using (500 gross per occupant) as his multiplier for the repair area, helps his toilet count! (warehouse, is the closest space function he/we can find?)

Why would you think warehouse is closer association than "Parking Garage"? Parking is specific to the inclusion of vehicles. As for the 200 square foot per vehicle, few vehicles are that large. Most would not take up more than 6' X 18' or 108 square feet, some much less. That leaves an additional 92square feet per vehicle for tools, space to work, drive paths etc. Also it is not all that uncommon for more than one mechanic, service person, sales person or supervisor to be around vehicles at the same time.

200 square feet might be a bit conservative but at least you have a clear association with parking of vehicles.
 
Big Mac, I agree with you that parking garage best discribes this use at a 200 OL multiplier, some times it helps to open the commentary book, the commentary list four types of garages.

The architect in this case is trying to reduce his occupant load to reduce his toilet count. I did'nt state that I agreed with the architects calcs. :)

GT anything new on this yet?
 
gbhammer,

I will have to go back and pull our set of plans, and get back to you and

the other Forum members. The building permit has not been issued

on this project yet. The owner has been "dragging his feet" for some

reason.

I haven't forgotten about "keeping the Forum" updated.
