City of Bellevue Submittal Requirements69ROUTING CHECKLIST for Mechanical Permits (BL) 9/27/2013To be completed by city staff:Structural review required? Yes No If yes, then respond to next question.(Reviewer: Reject BL application if structural review will be done as part of the BL and missing structural information)Separate building permit required? Yes No Bldg. Initials_____(Reviewer: Accept BL application if structural review will be done under a separate building permit even if missing structural information)(Permit Tech: If no is checked then add structural reviewer to routing)Land Use review required? Yes No LU Initials_____Complete this checklist prior to application.1. Is any equipment located on the exterior or vented to the exterior of a building? (examples: rooftop or wallmountedequipment, generators, HVAC equipment, exterior louvers, vents or exhaust terminals, gas piping) Yes – Land use review required. Land Use Submittal Requirements sheet 71. No2. Does the work include installation or modification to a fume hood, lab, chemical storage, paint spray booth, fueltank or kiln? Yes – Fire review required No3. Does the work include installation of an emergency or stand-by generator? Yes – Land use and Fire review required No4. Does the work include installation of uninterrupted power source (UPS) equipment? (examples: battery storageand recharging facility) Yes – 50 gallons or more of electrolyte – Fire review required Yes – less than 50 gallons of electrolyte No5. Does the work include the installation of a kitchen grease duct exceeding 75 feet in length? Yes – Fire review required No6. Are structural or fire rated improvements needed for the mechanical installation? (shafts, walls, exteriorscreening, rafters, beams, etc.) Yes – A separate building permit is required No7. Is any equipment over 400 pounds? If yes, please see attached document. Yes No8. Does the work include the installation or modification of a Type I or Type II kitchen hood? Yes – Commercial Kitchen Hood checklist must be submitted NoPLEASE NOTE:For roof-mounted mechanical equipment, provide architectural elevation views with your mechanical permit application toverify that new or existing screening is in compliance with the Land Use Code.Mechanical units are not allowed in side-yard setbacks in residential districts & properties adjacent to residential districts.Separate permits are required for Fire Alarm, Fire Sprinkler, Structural Building Improvements, Electrical, Smoke Control,and Plumbing if that work is being done as part of your project. See “Building Code Requirements for MechanicalInstallations” (next page) for coordination of structural and mechanical permits.If a fuel-fired boiler > 200 MBH is going to be installed, a separate permit is required from Washington State Departmentof Labor and Industries (L & I) Boiler Division. Contact Labor and Industries at Boiler@lni.wa.gov or 360-902-6400.The answers to the above questions are accurate to the best of my knowledge._________________________________________________________________________Signature of Owner/AgentDate

A separate building permit is typically neededfor structural improvements to allow for review and inspection of those improvements. Some examplesof typical structural improvements done as part of an HVAC installation include: Modifications to an existing roof or elevated floor to carry the weight of new equipment. Installation of screening as required by the Land Use ordinance. Connection of wall-mounted installations to an existing building.Building plans and structural calculations are required in most cases to justify existing and/or newconstruction related to gravity or lateral support of new HVAC equipment. Note: If structuralcalculations are required by the City of Bellevue, the calculations, details, and drawings must bestamped and signed by an engineer licensed in the state of Washington. Please review Table A on thenext page to determine if and when lateral engineering is required for your project.Structural improvements not listed below require a separate building permit. Note: If a separatebuilding permit is required, the mechanical permit will not be issued until the building permit is approvedfor issuance. If a separate building permit has already been submitted for review or has been issued, itis not necessary to provide the same information with the mechanical permit application. New HVACequipment should not be installed on elevated roofs or decks until necessary structural improvementshave been completed and approved by the building inspector.If screening for exterior equipment is required, per the Land Use ordinance, provide lateral and gravitycalculations for review. For projects requiring installation of shafts, plans & details showing the locationand support of vertical and/or horizontal shafts must be provided. In many cases, shafts must be fireresistance-rated; assembly listing numbers and assembly details must be provided for review.When is a separate building permit not required?The following items are considered ancillary to the mechanical work, do not require a building permit,and may be reviewed as part of the mechanical permit: Seismic connections to prevent overturning of equipment during an earthquake. Creating an opening in an existing roof and installation of a curb to support new rooftopequipment. Blocking and/or brackets to support ductwork. Review of an existing roof or elevated floor assembly for new gravity loads when no structuralimprovements are needed. This review is necessary to confirm that an existing roof deck, floorframing or platform is adequate to support the new or replacement installation. Engineering for gravity is not required for rooftop equipment if the new unit will be in the samelocation and the weight does not exceed 5% more than the original equipment.

Structures with (I p) = 1.0: The attached Table A specifies the City of Bellevue-approved seismic bracing requirements. [Importancefactor (I p) as defined in ASCE 7-05]2. Structures with I p > 1.0: All projects with I p > 1.0 require an engineered design of seismic bracing systems for all mechanical (M),electrical (E), plumbing (P), sprinkler (S) j , fire alarm (FA), and smoke control (SC) system components when the system componenthas been assigned an I p of 1.5. The component I p shall be taken as 1.5 if any of the following conditions apply.a. The component is required to function for life-safety purposes after an earthquake, including fire protection sprinkler systems.b. The component contains hazardous materials.c. The component is in or attached to an Occupancy Category IV structure and it is needed for continued operation of the facility orwhere its failure could impair the continued operation of the facility.Table AGuidelines for System Component Seismic Bracing where I p = 1.0a. 4’ dimension measured from the floor to the mounting point location.b. Mechanical, electrical and plumbing components with flexible connections installed between the components andassociated ductwork, piping, and conduit.c. Water tank restraints required per UPC Section 508.2.d. Engineering for gravity not required when mounted at slab on gradee. Lateral engineering for nonsuspended equipment is not required when the height/width ratio is < 1.0 (in all horizontaldirections)f. Engineering shall address the bracing system, the point(s) of attachment, and the capacity of the building element orstructure supporting the attachment and bracing system.g. Rooftop equipment: Engineering for gravity is not required for rooftop equipment if the new unit will be in the samelocation and the weight does not exceed 5% more than the original equipment.h.
