Am I correct in reading the 2010 ADA Standards and the new CBC that library book stack aisles that serve both sides must be 44" wide, or 36" wide if they serve only one side based on the requirements stated in 11B-403.5.1?
The new hotel building is a 4-story type VA that sits on a type I podium used for parking and entry lobby. There is also 1-1/2 levels of basement parking. The second floor has a restaurant and guest units on the same level. Because of the sprinklers, we are able to raise it 1-story and an additional 12,000 sf. Will the sprinkler help per floor to increase the allowable area (table 503) which is 12,000 to a much higher figure for the sum of ratios calculation? Based on 506.4, the sum of ratios for Group A & R and some others cannot exceed 2 in multi-story buildings. The numbers add up to more than that (3.25 to be exact) especially adding one more floor due to sprinklers. Can you subtract areas that are non-occupiable such as restrooms, corridors, and stair/ elevator shafts? It's hard to get a sum of two. Is it a catch 22?
We've got an all metal carport next to a 2 story R-2 apartment building. The carport fascia is 8'-0" from the apartment wall. We have taken the area increase for fire sprinklers and the building fits into the Type V-B allowable area, including the area of the carport. Does the carport require fire sprinklers?
Our firm is currently working on four multi-family projects under the current CBC and we're receiving conflicting information about whether or not our permits, when issued in 2014 will have today's building code requirements grandfathered, or will be required to meet the 2014. This is particularly critical due to energy requirements and minimum threshold standards going up 25% according to our MEP's. Any feedback would be greatly appreciated.
Can two different door rough openings use the same king stud? The pocket door header would be 2 x 10s butted up to top cap. I would be able to either use very long nails to go through the upper cripple stud of the left door through king stud into header of pocket door or maybe use lag bolts instead. I need to use the existing king stud for both doors to allow needed width of pocket door for wheelchair access. This is a load bearing inside wall and I could use the needed double jack studs on each end.
We have a long corridor and I check in NFPA 101, the travel distance to exit from corridor shall be 30 mtrs also there is a chance of the movement of Fire & Smoke.
We have given additional exit door to come up with the problem with the travel distace. But, to limit the smoke or Fire movement we have to provide the Doors in the corridor. I cannot find the in NFPA the Fire Rating of the door. I check NFPA 101 and 80. does any one have any suggestion
Does anyone know if the bathroom fan can be used for the fresh air ventilation for small 2 bedroom apartments (600-800 SF)? We would like to use recirculating range hoods and omit the kitchen exhaust fan.
