Page 2 of 3 <br /> I am a little confused on the roof construction proposal. In one detail it shows complete roof assembly and then <br /> detail talks about open air roof.Can you please clarify. <br /> ( v-t' 1 a [las fi'c_ roof: <br /> Thank You, AA' ii(711 *red- <br /> /a �< <br /> Chris Trussell / /� <br /> Marion County Building Inspection • �^ �` p VOW <br /> Building Inspector/Plans Examiner I�H'� SnQL �1 Llp��) �3 T3 �D n"fkY jlO <br /> Phone- 503-566-3977 I 11 _ (won o r C 1 II„ r4 ki <br /> Fax- 503-588-7948 a)/�.

This would be engineered of <br /> course,with sprinkler system. This would be allowed for the Type VB construction and based on our discussions <br /> meet the written requirements of the code. <br /> Our proposed alternate method is the currently designed configuration of the skylight system. As the application <br /> form states,the provisions of the code are not intended to prevent a method of construction not specifically <br /> prescribed by the code. We offer that the alternate method is, in our professional opinion, equivalent in all <br /> respects regarding safety of the building occupants, which is what we all care about We do not see any aspects of <br /> the alternate method that are less safe than the intent of the code. <br /> We submit this will all due respect and wish to formally request the alternate method we have discussed verbally. <br /> We believe on all counts that the alternate method is more safe and effective and meeting the intent of the code <br /> including limited area for the plastic skylight(coverage issue), minimizing risk to maintenance staff on the roof <br /> (curb issue), and limiting the amount of combustible materials and overhead structure overall (fuel load and <br /> overhead structure).- <br /> We respectfully request consideration of the alternate method request. <br /> Please let me know if you have any questions. <br /> Kent R.
