Large Diameter poured in place storm manholes
(OP)
I am trying to find a detail for poured in place large storm manholes (for 48" to 66" pipe). Could anyone direct me to either a site or a publication w/ a typical detail for this? All my details are either pre-cast or brick of which neither will apply to this condition.
Thanks
Thanks

Sorry David, but the last one I did was three companies ago for a connection in Chicago. Suggest you contact the Engineer's office for the agency that you need to make happy.

look at page 80 of the .pdf (std dwg RDM-010-05)
A KYTC type C manhole should work for your application. There are 3 more pages of steel details and quantities.

Oh yeah, and FYI dont believe a contractor when he tells you he can pour-in-place manholes LOL.... I allowed that substitution at a pre-bid conference and These guys can even set the molds correctly..(avoid the headaches and require pre-fab!!)

I can't imagine that brick would be 1) that much easier to construct, and 2) perform any better long-term.
I agree that CIP manholes - especially large-diameter and/or deep require a skilled (and better, experienced) contractor to construct.
