Mr. Ismail Mohammad 2713 Maple Street, LLC Plan Check Number: B2101-051, Second Building Review February 10, 2022 10. The proposed design includes demolition and reconstruction of the mezzanine. The mezzanine level was integrally constructed with the east exterior bearing wall, but did not contact the north and west walls; connection to the south wall is not clear. Reference the "Typical Wall Section" in record drawing 'Sheet 4/6" on Sheet A1.2. Section C/A4 indicates that the Second Floor framing will be integrally constructed with the existing walls; it is not clear how this will be accomplished. The connection to the north and south walls is not indicated. Details clarifying the connection of the floor framing and walls should be provided. At a minimum, the walls require lateral support at this level per Section R301.3 Item 1. 11. Continuing with the previous comment, the construction of the new stairs in the northeast and southeast corners interrupts the lateral support at the Second Floor discontinuity of the east wall studs. In addition, the studs along the stairs on the east, north, and south walls exceed the maximum allowable height of 11'-7" per Section R301.3 Item 1. Revised wall framing and details are required. Calculations substantiating the wall construction for bearing and out -of - plane loading for all sides of the building, including top and bottom restraint by the foundation and roof, should be submitted for review. See Section R301.1.3, and IBC Sections 1603.1, 1604.1, and 1604.4. 12. The construction of the new stairs in the northeast and southeast corners interrupts the lateral load path between the Second Floor diaphragm and the shear walls, particularly along the north and south walls. Due to the diaphragm span exceeding 25 feet, engineering is required per Section R301.1.3. The diaphragm edges should include collectors to transfer the shear loads to the supporting braced walls. Calculations substantiating the collector design should be submitted for review. Design should comply with ASCE 7-10 Section 12.10.2.1 including overstrength. See IBC Sections 1603.1, 1604.1, 1604.4, and 1613.1. 13. The Second Floor Plan on Sheet A2 specifies removal of two skylights. Details to infill the roof structure should be included. See Section R106.1.1. This review has been performed for general compliance with the building codes as adopted and amended by the state of Washington and the city of Everett. Corrections and comments made during the review process do not relieve the project from compliance with code and permit requirements. The designers -of -record are responsible for a complete design in accordance with the laws of the state of Washington.
