Your application has been received and a permit set up. However, the submitted documents are not sufficiently developed for us to perform a comprehensive review at this time. Construction -level documents should be submitted for review. Two complete sets of the revised drawings should be submitted to replace the previously submitted drawing sets. Preliminary comments are provided below to assist in preparing the drawings, but these are not intended to provide a comprehensive review. The resubmittal documents should include an itemized response letter clarifying how the review comments below have been addressed. Intake Review Comments: 1. Verify that the existing unit was installed with a valid permit. Replacement of an existing unit that was not permitted will require evaluation of the existing structure for the new unit. Depending on the age and construction of the building, and the estimated age of the unit, this is something that can be discussed further as a permit history on older units is often difficult to verify. 2. Where the existing unit has been installed with a valid permit, the drawings should include the weights of the existing and new units, and demonstrate that the new unit does not increase the previously permitted lading condition on the roof by more than 5%. The weight of all accessory components (e.g., mounting curbs, operating weight with fluid, etc.) should be included. If the load increase exceeds 5%, a structural analysis of the supporting framing is required. See 2018 IEBC Section 706.2. 3. If installation of the unit requires substantial structural modifications to the supporting framing, a building permit will be required. The application should include drawings and calculations for the proposed modifications. Minor modifications (e.g., blocking between existing framing, curbs, sheathing penetrations that do not cut framing members) may be performed within the scope of the mechanical permit application. 4. If the unit is suspended, details and calculations for the gravity supports and lateral bracing of the unit is required if it exceeds 20 lbs. See IBC Section 1613.1 and ASCE 7-16 Chapter 13. 5. Details will be required when penetrating fire -rated assemblies; the applicant is responsible to evaluate the building and determine the Construction Type of the building per IBC Section 601, and the locations and ratings of assemblies. Penetration details should be provided for the rated assemblies per IBC Chapter 7. 6. The drawings should list additional required permits as follows: a. A Plumbing permit is required when the unit requires connection to the plumbing system(s), such as water supply and/or discharge lines connected to an HVAC unit. b. An Electrical permit will be required for work involving components that are hardwired to the building's electrical system.
