What is the fix for 1/2" weld holes in 20ga. composite floor decking? Not what contractors usually do but a standard requirement this is a USACE project. Please provide the standard (SDI?) where I can find it.

The 6" line that enters the building vertically through the slab is called what? I have always considered it a riser however someone else is arguing it's a standpipe.

The contractor is installing his 1 1/2" branchline through a core in wood ceiling joist. The cores are approx. 2", does this allow for the proper movement in seismic catagory C. Is there any bracing required since the movement is fairly restricted? I am use to seeing pipe supported from...

I was recently ask to verify the light brightness from strobes mounted on high ceilings (approx. 16') by a triangle method. Does anyone know what that is and how I perform the test? I think the strobes are set at 95 from the manufacture but the building official doesn't think it will be bright...
I am inspecting 1 1/4" sprinkler branchlines that are being supported from the structure overhead with 3/8" threaded rod. Is there a maximum lenght for the threaded rod ? I know rod stiffners are required on bracing however this is not bracing. The threaded rods are approx. 18' in lenght. Due to...
Does anyone know a good product to verify block fill and latex paint coverage? As a third party inspector I have been ask to verify coverage. I do not want to stand around and verify coverage per a 5 gallon bucket. Any suggestions?
