Upon submission of two sets of drewings and a signed <br /> stamped letter from a professional engineer reflecting the information requested, your application will be <br /> given priority anc� plan review will resume. <br /> Mechanical <br /> 1. All submittals should include (as applicable) the following: <br /> a. Cubic feet of air per minute (CFM) at each air diffuser, return air register, exhaust and transfer <br /> grill; size of ducts and outlets; equipment schedule of brand names, fuel type, model numbers, <br /> input and output capacity, tons of cooling, efficiency ratings, CFDt capacity, motor efficiencies, <br /> and unit weights; and locations of smoke and fire dampers. <br /> b. Combustion air source, size and locations. <br /> c. Make-up air system required to meet IMC, WSEC requirements. <br /> d. Roof parapet and screening, where applicable or required. <br /> e. Structural details and caiculations wet-stamped by a certified Washington State Design <br /> Professional for all suspended or rooFtop mechanical units greater than 400 pounds. <br /> f. Anchorage details for mechar�i;al equipment to meet structural seismic and static loads. <br /> g. Manufacturers' installation instru�tions/catalog cut sheets for all equipment speclfied. <br /> 2. An economizer is required for the new medianical air handling units, unless documentation is provided <br /> otherwise indicating conformance with !^.�SFC section 1424 Economizers. <br /> 3. The location and weight of the new air handling units requires review and stamped structural <br /> verification by a Washington State licensed professional engineer. <br /> a. Either the professional engineer should write a letter with a wet stamp to verify that the <br /> existing structure will carry the weight (this lelter can be sent by e-mail); or, <br /> b. The professional engineer can send an e-mail verifying that the current mechanicaf submittal <br /> was reviewed by the engineer, and the location and weights of the units has not changed since <br /> the structural drewings were designed and submitted for building permit; or, <br /> c. If the existing structure is not sufficient to carry the weight or resist the seismic impact of the <br /> new air handling units, the engineer will need to submit wet-stamped framing plans, details and <br /> calculations for structural revisions required. <br /> If 2 <br />
