Permlt Counter <br />This letter outlines several of the standards and guidelines that are being used in the design of the <br />High Bay Factory Office Build -Out project. <br />In general, the 1990 High -Bay Factory Expansion served as the baseline for design criteria and <br />building code interpretation. The 1990 High -Bay Factory Expansion was designed under the 1988 <br />and 1991 editions of the UBC. We attempted to remain as consistent as possible with the 1990 <br />High -Bay Factory Expansion project in our interpretations of the UBC, and in the application of <br />specific variances that were granted by the City of Lverett for that project. These interpretations <br />are described below. The current High Bay Factory Office Build -Out project is designed under the <br />1994 edition of the UDC. Issues specifically related to the interpretation of the current code are <br />also described below. <br />I. In general, exit potential to the tunnels is increased from all levels, since additional stair <br />towers will be built to provide two means of egress for the new office areas. In no instance <br />does the occupancy of a new office level create a load on the tunnel exitway larger than i <br />the factory floor. The pedestrian tunnel exit width is sufficient to meet the combined <br />tributary areas of the factory Floor and tower levels. 10 o 0o i c if <br />2. The occupant load for the factory floor is I occupant per 1000 s.f. This is consistent with <br />the occupant load factor used in the 1990 High -Bay Factory Expansion. <br />3. No new spaces are assembly areas. 1) <br />ie, <br />4. The tower office spaces are subordinate uses to manufacturing, and are considered to be <br />mezzanine levels. This is consistent with the 1990 High -Bay Factory Expansion. -- <br />Of ccll CL-FV, LAIRY, Sri -> � Lr V S/>+ M wil h f'RFsfARIrp <br />ly <br />
