NOTES AND COMMENTS*
NOTE: These Plan Review comments reflect submitted construction documents omissions and
deficiencies that we have identified in our review. The construction documents shall be revised in
accordance with the comments and the referenced code sections. Prior to approval of the project, the
1. INFORMATIONAL NOTE: The materials submitted for this plan review project depict anew one-story,
slab -on -grade building with mezzanine level intended for worship and other assembly uses.
The main floor of this building is arranged as a Chapel with its fixed pews and Rostrum platform where
the main worship and religious services are held. Accordion folding partitions separate the end of the
Chapel from the Overflow area and from the Cultural Center. The Cultural Center can also be
subdivided with accordion folding partitions. This space will be used for indoor sporting activities and
other general assembly functions. At the far end of the Cultural Center is a stage Platform. The
building also contains numerous large meeting rooms such as the High Council Room, Rooms 113
through 115 with their integral Serving Area and Rooms 123, 134, 136, etc. All of these rooms, spaces
and areas are classified as Assembly Group A-3.
It appears that Rooms 141, 142 and possibly 140 will be used as';cry rooms" or as a child care facility,
but only during the worship and religious services. If so, these rooms are considered as part of the
main use and occupancy. If these rooms provide child day care services outside of the normal church
activities, then they must be classified as Institutional Group 1-4. Further design information must be
submitted for these rooms to determine the applicable code requirements.
This building also contains various labeled and unlabeled partitioned offices, clerical rooms, work
rooms, etc., that will be used to conduct the business and administrative functions of the church.
These rooms and spaces are classified as Business Group B. The nonseparated uses option will be
used to evaluate the mixed use groups and occupancies (A-3 and B) present in this building. Based
on a full street frontage area modification increase and the automatic NEPA 13 fire sprinkler system
building area increase, the Type VB construction specified on the drawings provides the necessary
height and area allowances for this building. The 70' high noncombustible steeple does not add to the
building height in terms of "feet".

Example #1: Cultural Center #165 and #166, which appears to be supplied 1,360 cfm of outdoor
ventilation air, must be provided 6,720 cfm of outdoor ventilation air (Auditorium: 2,982 sq. ft. x 150
people/1,000 sq. ft. at 15 cfm/person).
Example #2: Rostrum #162, Chapel #163 and Overflow #164, which is supplied 2,540 cfm of outdoor
ventilation air, must be provided 13,980 cfm of outdoor ventilation air (Auditorium: 6,210 sq. ft. x 150
people/1,000 sq. ft. at 15 cfm/person).
Example #3: High Council #103, which appears to be supplied 149 cfm of outdoor ventilation air, must
be provided 540 cfm of outdoor ventilation air (Conference: 527 sq. ft. x 50 people/1,000 sq. ft. at 20
cfm/person).
Please submit a ventilation schedule. Included with the ventilation schedule should be documentation
which indicates the applicable outdoor ventilation air rates from Table 403.3 and the occupant load or
occupied floor area used to determine the amount of outdoor ventilation air supplied to each room and
space. (105.2, 106.3, 106.3.1, 401.2, 401.3, 402, 403.1, 403.2, 403.3, Table 403.3, 405. 1)
5. Indicate the nature of the cooking in the kitchen areas with the ranges. Please note that the amount
of grease laden vapors which will be produced to warrant the installation of Type I kitchen exhaust
hoods, grease ducts and fire suppression systems shall be subject to the discretion of the code official.
As previously indicated in Comment #3, the ranges are specified in the project manual to be used as
domestic cooking appliances. Therefore, if the cooking appliance is only used for warming or is used
similar to a domestic cooking appliance, a kitchen exhaust hood is not required to be installed above
the appliance. Final approval that neither a Type I nor II kitchen exhaust hood system is warranted
rests with the code official. As a point of information, Section 507.2.2, Exception #4, of the 2006
Mechanical Code would not require a Type II kitchen exhaust hood system to be installed above some
light-duty cooking appliances as long as the additional heat and moisture loads generated by such
appliances are accounted for in the design of the HVAC system. (505, 506, 507, 508, 509; 2006 IMC
