Mr. Jason Beagle Merrick Lentz Architect Plan Check Number: B2212-020, First Building Review February 3, 2023 Structural 1. The project proposed demolishing a portion of the existing concrete wall to modifying the door opening. See IEBC Section 806.2, and IBC Sections 1603.1, 1604.1, 1604.2, 1604.4, 1901.2, and 1901.5. The following comments should be addressed: a. A structural partial plan for the area around the modified opening should be provided indicating the structure above bearing on the length of wall to be modified (e.g., beams, girders, columns, posts, walls, pilasters, etc.). b. Section 3/S-1 should be revised to specify the dimensions for the remaining wall section. c. Section 3/S-1 should be revised to indicate the remaining reinforcement. The wall should be scanned to accurately determine the sizes, numbers, and locations of rebar in the wall. See ACI 318-14 Section 27.3.1.2. d. Documentation substantiating the condition and strength of the existing concrete should be submitted for review. See ACI 318-14 Section 27.3.1.3. e. Calculations should be submitted substantiating the flexural and shear capacity of the wall. Note that the wall supports the existing URM wall above that provides a bearing load path for both the upper floors and the roof. f. As an alternative to Items (b) through (e), a new supplemental gravity frame with foundations should be installed to support the existing structure. Calculations substantiating the design of the frame and foundations should be submitted for review. 2. Plan Note 3/A-1 states that the manufacturer shall provide connections of the lift to the existing structure. The structural drawings are required to provide a sufficient base for the installation of these connections; this is not provided by the manufacturer. Details and calculations providing lateral anchorage and support for the new lift system should be submitted for review. The existing floor system should be modified to provide a load path into the diaphragm to transfer the lateral forces. See IBC Sections 1603.1, 1604.1, 1604.2, and 1604.4 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. If you have any questions or require additional clarification, please contact us.
