Re: Rainier View Estates Civil Review # II
The 2 gate valves shown by the 45 degree bends should be eliminated. Only 1 gate valve should be provided for this project and it should be located at the mid point of the pipeline.
All fittings should be Slip X Slip with thrust blocks. No MJ fittings are allowed.
If pavement is to be placed for the driveways for lots 8 and 11 during this project, the service lines and toning wire will need to be installed.
Vertical 22 ½ degree bends are shown on the drawings in the 2” main. These are shown as MJ fittings. No MJ fittings are allowed. And all bends need thrust blocking. I suspect that these
bends could be accomplished with a slight deflection of the pipe.
