The following is our response: <br />1. IBC 1021 requires two exists from the parking level. These exits will need to be <br />separated in accordance with Section 1015.2 <br />a. Agreed. Note the revised CP0.0, CP1.0, A1.0, A5.1, A9.1 adding an exit door <br />from the Parking Floor. <br />2. IBC 1604.5 indicates an occupancy category of III which appears to require a <br />revision of the structural design. <br />a. IBC 1604.5 and Table 1604.5 for Occupancy Category III Buildings and other <br />structures whose primary occupancy is public assembly with an occupant <br />load greater than 300. <br />b. While the Municipal Court is an A-3 assembly facility it's primary use is not for <br />public assembly. Public assembly is typically determined as gathering for <br />worship, entertainment, eating, drinking, or amusement. Risks associated <br />with public assembly are from high density of occupants and in some cases <br />darkness. <br />(, , c. IBC 1604.5 Commentary (see attached) indicates that the determination <br />K \ should be based off of the "primary occupancy is for public assembly is more <br />/ than 50% of the total building. The assembly area includes the courtrooms <br />InVR/ and public lobby is 6,080 sf. The first floor area is 16,256 sf. The total <br />building area is 23,936 sf. Depending on how the determination is calculated, <br />the assembly use area is only 37% of the first floor or 25% of the total <br />building area. <br />/ d. Based on the IBC Commentary this building does not need to be designed <br />II ` under the Occupancy Category III, but under the general building Occupancy <br />Category II. <br />3. The inmate toilet does not include the clearance around the water closet per <br />IBC/ANSI Al17.1, section 604.3 <br />a. Agreed.
