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 /> 42( 11)) a pIa25 fi‘c rout <br /> Thank You, �4nn / <br /> Noj kilo 0)<`,7 (I(Ye CCd (CPivaeJ/ <br /> Chris Trussell <br /> Marion County Buor/than Inspection <br /> Examier Sec r1)r 2 O•c �3 �3 ��O Building Inspector/Plans Examiner 'J�'�, <br /> CAI 46 'ROW <br /> Phone - 503-566-3977 /(, 0 y/� <br /> Fax- 503-588-7948 av U p" 1co n or S'"I�/' `p 4c.e k <br /> -Rurt faf ih WiA cie.

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.
