provided by the type of constriction used for the building. The greater the potential fire <br /> kir hazards indicated as a function of the group, the lesser the height and area <br /> allowances for a particular construction type. <br /> As documented here and noted in the IBC Code Commentary, the entire code is based on the "equivalent <br /> risk theory'. In this building remodel project, if we look at those three interdependent considerations, we <br /> find that the proposed design with interior fire sprinklers and HT protected exterior canopy provide a <br /> satisfactory level of protection for the occupants. (1)The fire hazard is one of the lowest as a B- <br /> occupancy especially as compared to the previous use as a heavy equipment repair shop. (2)The total <br /> floor area is less than the maximum allowed for a building of this type and occupancy that does not have <br /> any fire protection features. (3)The overall fire resistance,while not required, is bolstered by the interior <br /> fire sprinklers and the 1-hour equivalent heavy timber construction of the canopy. <br /> SUPPLIMENTARY INFORMATION: <br /> LIST SUBSTANTIATING EVIDENCE(REPORTS, STUDIES, ETC) —ATTACH COPIES OF <br /> DOCUMENTATION <br /> • "Fire Design of Mass Timber Members", Wood Works Wood Products Council, May 17, 2021 <br /> o Provided basis of Heavy Timber construction evaluation for fire resistance and char effect <br /> • Alternate "What-If"code summary analysis without Fire Sprinklers <br /> C <br /> L <br /> Page 3 of 5 <br /> CARLSON VEIT ARCHITECTS, P.C. <br /> 3095 RIVER ROAD NORTH • SALEM, OREGON 97303 • 503-390-0281 • FAX 503-390-2459 <br />
