I received this question on a practice exam case study. The only resource to use was the IBC (the others were site photos and a contract). I cannot locate the right code section or other resource in which to find the answer.
The architect is developing the roof assembly for a ‘green roof’. The supporting roof structure must have the necessary load bearing capacity to support wet densities. What is the “pcf” range?
I did find IBC 1607.12.3.1 but it discusses 20 pSf vs pCf. The answer was 60-90 pcf. Any ideas?
