We have completed the first review of the building plans for this project. This email will serve as the review letter. The comments below should be addressed. Two revised full-sized hard-copies of the drawings should be submitted for review. An itemized response letter stating how each comment has been addressed should be included with the drawing. Additional revised documentation, including but not limited structural calculations and other supporting documentation,should be submitted as required. Comments General: 1. The construction drawings appear to show more units that indicated in the application, including but not limited to multiple AHUs and an ERV. The location of the minisplit systems is not clear. The drawings and application should be revised as needed to consistently indicate the proposed work. 2. A schedule for the mechanical equipment should be included in the construction drawings. The schedule should list the operating weight of each unit. Architectural: 3. The drawings indicate penetration of vents through the floor system into the story above. Details for the concealment of the vents should be included. In addition,fire-rated penetration details should be included if the vents penetrate rated construction. See IBC Section 714. Structural: 4. Details for the support of the mechanical equipment should be included in the drawings. The supports should include lateral bracing. Calculations substantiating the design should be submitted for review. See IBC Sections 1604.1 and 1613.1, and ASCE 7-16 Chapter 13. 5. The project appears to require cutting large openings in the concrete walls. a. The size and location (i.e., horizontal and vertical) of the openings should be specified. b. A letter sealed and signed by a professional engineer licensed in the state of Washington should be submitted stating the impacts of the new openings on the structural performance of the walls. c. Additional construction details notes provided by the structural engineer should be specified in the drawings. Information may include but is not limited to demolition and opening reinforcement details. Please contact me if you have questions. Thank you. � I
