10/1/18
3 X The plans call for (4) 4” ductile iron MJ 45 bends, are you requiring all the fittings on the sewer force main to be ductile iron or just those (4)?
Please clarify. The (4) each 4‐inch MJ 45 Bends shown on sheet H.1 are part of the Sanitary Sewer. Sanitary Sewer pipe and fitting are PVC according to Subsection 708.05.
10/1/18
4 X Clean‐out detail on sheet H‐8 calls for a (threaded plug 12” with 2” square nut)‐ are you requiring the clean‐out to be 12” diameter on a 4” sewer main?
This will be addressed in a forthcoming Amendment.
10/1/18
5 X Are you requiring restrained pipe joints on any of the 8” CL52 water main? Note 3 on sheet I.2 references a detail which shows minimum pipe joint restrained lengths near fittings, but it isn’t included in the plans or spec.

8 X Clarification to my question A3 ‐ MJ fittings are typically made from Ductile Iron and restrained with Mega Lug retainer glands. You can’t get an MJ PVC fitting. So, my question was inquiring if you would accept MJ AWWA C153 Ductile iron fittings with Mega Lug restraints on all the fittings?
Comply with the CRWWD Manual as called for in the SCR’s.
