If you feel that an item is not applicable to your project, note “N/A” and discuss the reason with the plan checker.Please indicate the sheet number and detail to the right of each correction, or note the number on the plans where the correction is made. Resubmit marked original, calculations and this correction sheet. A separate sheet for response may be used.Resubmit 3corrected sets of plans.Meetings between the project applicant/designer and the plan reviewer shall be by appointment only. Please call (714) 647-5830 for an appointment.7.1stPlan Check Comments: Sheet A0.4: Sheet A0.1 indicates building is a Type III-B construction, per 2013 CBC Table 601, exterior bearing walls require minimum two-hour fire rated construction. Fire resistive assemblies note #2 indicates 2 hour exterior wall assembly with GA file number WP8415. Reference WP8415 has been verified in Fire Resistance Design Manual. Please provide a complete 2 hour exterior wall assembly detail on the plan. For example, the type of fastener, fastener length, diameter, staggered joints, and minimum thickness shall be specified on the detail.Response: Fire Assemblies locations are indicated on Sheets A0.4, A0.5 and A0.6. Fire Assemblies details are shown on Sheets A0.7 and A0.8.2ndPlan Check Comments: Fire assembly details: WP3514, 7008, WP8415, FC5107, FC511, and D703 have been provided on sheet A0.7 and A0.8. Please specify the item number from Table 721.1(2) for one-hour CMU wall for Fire assembly #4. Specify the minimum thickness and the type of aggregate concrete under Fire assembly #5. Fire assembly #3 is identified on all exterior walls on sheet A0.4 and A0.5. Please show the 2-hour wall legend on the North Exterior walls and South Exterior walls on sheet A0.4 and A0.5Response: Fire Assembly #4 item number has been added and the minimum thickness and type of concrete has been added to Fire Assembly #5 – See sheet A0.4. The two-hour wall legend and plan references have been updated on sheets A0.4 and A0.5.3rdPlan Check Comments:The type of construction has been updated to Type “VA” construction. Fire assemblies on sheet A0.7, A0.8, A0.9, and A0.10 meet the minimum fire resistance rating requirements for building elements for Type “VA” construction. Please show the following table on the title sheet:Building ElementType V-A construction – Fire resistance rating requirements (hours)Primary structural frame1.0Bearing walls (Exterior and Interior)1.0Exterior nonbearing walls and partitionsSee Table 602Interior nonbearing walls and partitions0Floor construction and associated secondary members1.0Roof construction and associated secondary members1.0--1st Plan Check Comments: Sheet C-1: Show Fire Separation Distances on all four sides of the building. Note the North and South Fire Separation distance is measured from the face of exterior wall to center line of the street and alley, respectively.Fire Separation Distance. The distance measured from the building face to one of the following:The closest interior lot line;To the centerline of a street, an alley or public way; orTo an imaginary line between two buildings on the property. The distance shall be measured at right angles from the face of the walls.Response: Fire separation distancesare shown on Sheet A1.0.2ndPlan Check Comments:Fire separation distances are shown on the North side and South side of the building. Fire separation distance on North side of the building exceeds 30 feet. Therefore, the Northern exterior walls are not required to be fired rated. The Fire separation distance on South side of the building is 15 foot 7 inches. Per 2013 CBC Table 602, minimum of one-hour fire rated exterior wall is required for M, S-2, and R occupancies. In addition, Table 705.8 requires maximum unprotected opening to 75% of exterior wall area. On sheet A0.5, show “one-hour wall floor-ceiling” legend at the balcony area on the second-floor egress plan, second-floor mezzanine plan, third-floor egress plan, and third-floor mezzanine plan.On sheet A4.2, elevation drawing indicates 75% maximum opening area requirements are met on the second floor and third floor. However, the Fire separation distance is 15 foot 7 inches as established on the site plan. The 75% maximum opening area requirements are exceeded on the first floor. Since there are usable space between grid-line “E” and “F”, the Fire separation distance remains the same on the first floor. A meeting is recommended on opening protection requirements and alternative options before the next plan check submittal.Response: In accordance with our meeting the greater than 75% opening area on the first floor at the alley side of the building is being mitigated by providing a Water curtain with fire sprinklers. See note on First floor egress plan, sheet A0.4.3rd Plan Check Comments: Since the proposed water-curtain sprinkler construction is used in lieu of standard building Code requirements for opening protection per CBC Chapter 7, An “Alternate Materials, Design and Methods of construction” application is required. Please complete the “Alternate Materials, Design and Methods of construction” form attached. In addition, a licensed C16 Fire Protection Engineer is required to document the proposed water-curtain sprinkler system is equivalent or better than a 75% maximum allowable opening protection of exterior walls. This document shall be stamped and signed by the Fire Protection Engineer. Please submit the “Alternate Materials, Design and Methods of construction” application along with Fire Protection Engineer’s report for Building Official and Fire Marshal’s approval.
