MMP C(5): DEFERRED SUBMITTALS Please note all deferred submittals on the plans. All deferred submittals must be reviewed for general conformance by the Registered Design Professional before being submitted to Building Safety. All deferred submittals must be reviewed and approved by Building Safety prior to installation/construction. Reference: AMC 23.10.302.4.2 C(6): SPECIAL INSPECTION PERSONNEL The Owner shall submit a letter to Building Safety stating that special inspection personnel have been retained to provide special inspections required by IBC Chapter 17 and the Statement of Special Inspections. This letter may also be provided by the Special Inspector/Inspection Firm providing services. All special inspectors shall maintain current certification with Building Safety Special Inspection Program. Reference: AMC 23.15.1704.1.4 Comment remains. No response provided. This comment must be resolved before an F&F permit can be issued. WAB - 9/17/2008 10/13/08 - Not resolved. No information provided this review. MMP 10/21/08 - Resolved. NGE/TFT providing special inspection. Letter by owner to be submitted at preconstruction meeting by agreement. MMP C(7): STATEMENT OF SPECIAL INSPECTIONS Please provide a detailed statement ofspecial inspections in accordance with IBC Chapter 17. Reference: IBC Section 1705.2 Comment remains. The Engineer of Record is required to provide a statement of special inspections per IBC section 1705.2. Please provide. This comment needs to be resolved for F&F. Please note that there appear to be inspection requirements missing such as bottom of hole, setting of anchor bolts, etc. Each type with appropriate frenquency of inspection must be provided in the statement of special inspections which can be included in the drawings or as a separate document. Reference to IBC is not sufficient. WAB - 9/17/2008 10/13/08 - Resolved. Revised special inspection requirements provided on the plans. MMP C(8): BUILDING OFFSET AT PROPERTY LINE Refer to Sheet C1/3. Based on the civil site plan, it appears that the structure directly abuts the property line at the east. The building must be set back a minimum distance equal to the design inelastic story drift. Please coordinate this requirement with Title 21 requirements. Reference: ASCE 7 Section 12.12.3 Comment resolved. It doesn't appear as if the structure is against the property line. Per the section on sheet C2, it appears there is at least 40' separating the building from the east and west property lines. WAB - 9/17/2008 C(9): PILE MATERIAL SPECIFICATIONS Refer to Sheet S1.0, and Geotechnical Report Section 5. Neither the structural foundation drawings nor the geotechnical report note the material specifications for the piles. Please provide. Reference: IBC Section 1808.2.2, 1809.3.1 Comment no longer applicable; however see additional comments. WAB - 9/17/2008 C(10): PILE WALL THICKNESS Refer to Sheet S1.0, and Geotechnical Report Section 5. Neither the structural foundation drawings nor the geotechnical report note the minimum pile wall thickness required to resist stresses during pile driving operations or loads imparted from the superstructure. Please provide. Reference: IBC Section 1808.2.2, 1809.3.2, 1809.3.4 Comment no longer applicable. See additional comments. WAB - 9/17/2008 C(11): PILE CAPS Refer to Sheet S1.0. The piles are connected using W12 pile caps. IBC requires pile caps to be reinforced concrete, and shall include all elements directly attached (e.g. grade beams, slabs, etc.) Please provide revised details showing concrete pile caps. Reference: IBC Section 1808.2.4 Comment no longer applicable; however seeadditonal comments. WAB - 9/17/2008 C(12): ANCHORAGE OF PILE CAPS Please provide design calculations showing the adequacy of the pile cap anchorage to the pile. Reference: IBC Section 1808.2.23.2.2 Comment no longer applicable; however see additional comments. WAB - 9/17/2008 C(13): LATERAL RESISTANCE AT FOUNDATION Refer to Geotechnical Report Section 5.3. The report states that lateral loads shall be resisted by passive pressure on the pile caps and grade beams, and not the piles. In addition, it further states that the top 12 inches of soils should be neglected due to settlement or low compaction. The structural calculations do not address this requirement at all.Please provide. Reference: IBC Section 1604.4 Comment no longer applicable; however see additional comments. WAB - 9/17/2008 C(14): COLUMN BASE FIXITY Refer to Details 5/ and 6/S3.0. The details show base fixity; the column bases are welded to the pile caps. This will probably induce flexural moments in the columns that the pre-engineered building design does not usually consider. It is possible that the additional moments at the base will overload the column in flexure. Please justify by analysis, or provide reviseddetails. Reference: IBC Section 1604.4 Comment no longer applicable; however see additional comments. WAB - 9/17/2008 C(15): Helical piers are not specifically covered by code and require third party approval (i.e. ICC ES Report). We have also accepted an in situ load test as permitted by IBC section 1713. ICC ES acceptance criteria AC358 describes required testing on helical piers. Please note that there are special Geotechnical report requirements for helical piers. See section 6.8 of AC358. Here’s a link to AC 358: http://www.icc-es.org/criteria/pdf_files/ac358.pdf. Reference IBC section 1703.4. 10/13/08 - Resolved. Special inspection and testing requirements in accordance with ICC AC358 noted on the plans. Testing results and inspections shall be submitted to MOA prior to issuance of full structural approval. MMP C(16): A307 BOLTS Not all ASTM A307 bolts are weldable. Please specify ASTM A307 S1 as the anchor type to ensure that the contractor purchases weldable A307. Reference AAC section 23.10.302.3. 10/13/08 - Resolved. Note stating Supplement S1 requirement shown on S2.0. MMP C(17): STATEMENT OF SPECIAL INSPECTIONS Please provide a detailed statement of special inspections in accordance with IBC Chapter 17. This may beprovided on the plans or as a separate document. Reference: IBC Section 1705.2 C(18): BOLTED CONNECTIONS - SLRS Please note on the plans the requirement for all bolted connections in the seismic load resisting system (SLRS) to be installed slip critically, including Class A or better faying surface preparation. Reference: AISC 341 Section 7.2 C(19): WELDED CONNECTIONS - SLRS Please note on the plans the requirement for all demand critical welds to be made using filler metal capable of obtaining a Charpy V-notch (CVN) toughness of 20 ft-lbs at -20 deg. F. and 40 ft-lbs at 70 deg. F., and all other SLRS welds to be made using filler metal capable of obtaining a CVN toughness of 20 ft-lbs at 0 deg. F. Reference: AISC 341 Section 7.3
