Ms. Joanne Coghlan Plan Check Number: B2003-040, First Building Review April 8, 2020 Architectural 1. The proposed project appears to be located at 5208 S 2nd Avenue. The project address should be verified and the construction drawings revised as needed. Note that this comment is not duplicated for other disciplines, and should be applied to all drawings in the submittal. See IBC Section 501.2. 2. The construction drawings specify replacement of the existing bridge with a new aluminum bridge. The existing guards shown at each end of the bridge on Sheet A-1.0 are presumed to have been connected to the original bridge, but are not connected for the replacement bridge. The following comments should be addressed: a. Details showing the interface of the existing and bridge guards should be provided in the drawings. The guards should comply with IBC Section 1015.4. b. The guard ends that are not positively connected to the bridge structure should be modified to comply with IBC Section 1607.8.1. Details modifying the guards and their connections to the supporting structures should be provided in the construction drawings. Calculations substantiating the design should be submitted for review. c. Continuing with the previous comment, if connections are provided between the deck guards and the bridge,they should be provided with isolation joints similar to Detail E2 of the bridge drawings. Calculations substantiating that the joints comply with ASCE 7-10 Section 12.12.3. See IBC Section 1613.1. Structural 1. Structural special inspections are required for this project. The"Statement on Special Inspections"in the Structural General Notes on Sheet S1.1 stating that special inspections are not required should be revised. The statement should include a table listing each type of special inspection and shall specify the extent of each inspection(e.g.,continuous, periodic) per IBC Section 1704.3.1. See IBC Sections 107.1, 1704.2.3 and 1704.3. Required inspections include but are not limited to: a. Concrete post-installed anchors per IBC Table 1705.3(4). b. Steel construction per IBC Section 1705.2.1 and AISC 360-10 Chapter N. c. Aluminum construction per IBC Section 2002.1 and AA ADM 1-15. 2. Continuing with the previous comment,the project appears to include work that will be performed on the premises of fabricators'shops. Special inspections are required to be performed by the fabricators unless they are registered and approved to perform work without special inspections. The Structural General Notes on Sheet S1.1 should be revised to list work being performed by approved fabricators. Work not being performed by approved fabricators should be added to the list of special inspections. See IBC Sections 1704.2.5, 1704.2.5.1, and Section 1704.5 Items 1 and 2. 3. The bridge is connected to the existing building with an eccentrically-loaded joint per Detail 3/S3.1. The joint will induce torsional loads into the supporting beam. Calculations substantiating the resistance of the beam and other stabilizing framing should be submitted for review.
