MEP Reviews – This review does not include Mechanical, Electrical, and Plumbing (MEP).Architectural CommentsGeneralFirst Plan Review Comment:Architect-On-Record shall stamp and sign the plans.Second Plan Review Comment: The plans are still missing the architect’s stamp and signature.Senior Plan Check Engineer, Anson So, reviewed the architectural drawings. Assistant Plan Check Engineer, Jonathan Lo, reviewed the structural drawings. See page one for contact information.GA0.1.0 – Sheet IndexMechanical, Electrical, and Plumbing (MEP) sheets are on a separate permits. Omit sheets or reference ‘Per Separate Permits’.GA0.1.1 – Under Code ClassificationParking Count - One in every six accessible parking spaces is required to be a van accessible parking space. Increase the number of van parking space to ‘2’ under Retail Parking.Delete occupancy group ‘A-3’ and the ‘200 feet’ travel distance at the Exit Travel Distance Section. There is no A-3 occupancy on this parking structure.
Revise the code section reference to ‘CBC 602.2’ at the Type of Construction.
Under Area of Refuge, revise code section reference to ‘1009.3.3 exception 2’.
Under Fire-Resistance Ratings – Mechanical Shafts, reference section 712.1.10.3 for fire rating exemption.
Revise the Vehicle Barriers code-reference section number to CBC 406.4.2.
Sheet GA2.1The 3-hour firewall along gridline ‘A’ ends at gridline ‘3’. Without the benefit of a firewall separation between gridline 1 & 3, The Fire Separation Distance (FSD) governs the fire protection level on the exterior walls and its openings. Depending on the location of the imaginary property line, the first FSD is measured from the apartment building to the imaginary property line. The second FSD is measured from the parking structure to the imaginary property line. Determine the two FSD and verify that openings does not exceed the allowable opening areas per CBC Table 705.8.[End of Architectural Comments]General StructuralClarify the extent of the ground improvement area. Please attach the ground improvement drawings to the structural plans for reference. Provide the design of the ground improvement mitigation method (listed by approved agencies. E.G. ICC) to mitigate the effects of liquefaction and for support of the porposed conventional foundation system.Per amendment of soils report, all isolated column pad footings shall be connected in at least two directions by grade beams. Please update foundation design.PC #2: Letter not found in provided resubmittal. Please provide either PDF or hard copy.Add note to the cover page of the structural plans that “The design of the ground improvement mitigation method to mitigate the effects of liquefaction and for support of the proposed foundation system shall be designed by a licensed professional and reviewed and approved by the geotechnical engineer and the structural engineer in record”Foundation design shall be reviewed by the geotechnical engineer. Geotechnical report recommendations are considered to be minimum standards. Structural calculations and drawings must meet or exceed said minimum standards. Verification of review may be by a “review stamp” on the foundation plan or by a letter on their letterhead. (1803)DrawingsSheet GS1.1Please provide address on the title block on each sheet. Provide sheet index on first sheet.PC #2: Add sheet GS6.4 to sheet index.Provide Risk Category and Analysis Procedure used for design in General notes.
