Hi Jeanne,
FYI. We have an issue where the existing 6"SS IE connection point requires us to come up and over the new 12" SD—this
will create a problem for the 6" Waste leaving the building. I think we have a fix with the information listed below from
Chris. I can have Chris formally submit this to your department. Regards Bill Bacon 206-518-225 „

Hi,
Please see the attached,
Probably need to clear this with Jea �,!'!. I checked the flow capacity of the pipes at 0.251.1/o -rvlthe 100 -year flow, they're just at
capacity.
3ill, that discrepancy that Charlie caught was a typo.
We can update the sewer profile at as -built, once we know all the stuff coming from the building and all.
Thanks,
Chris

Thank -you Chris this will work. I will ask Michael to submit a formal RFI to you for your response. We are just waiting on
Holaday-Parks to confirm their stub IE outside of the building. Cheers
Michael, all good to go on submitting an RFI.

Hi all,
See Profile 6/C5.3
If we run the SD pipes from CB-03N(Kristar) to CB -02N to CB -01 at 0.25%, a preliminary look indicates that we could do the following:
• CB-03N—Outlet 393.77 (same)
• 29 -LF @ 0.25%
• CB-02N—Inlet/Outlet 393.69
• 33.06 -LF @ 0.25% to crossing with 6" SS side sewer
• SD IE at crossing 393.60
• If 6" SS IE at crossing can be at 392.65, and assume 3 -inches of total pipe thickness for both pipes.
• There should be a couple inches of separation (for an ethafoam pad).
Thanks,
Chris

Right now the existing SS IE is 392.65' at where the pipe will cross over. Looking at the photo the new 12" SD will be
right over the SS connection point. I am asking Holaday-Parks to combine the 3" & 6" waste at 394.86' outside of the
building. They cannot do it under slab due to plumbing code. Yes we should provide a clear separation (bond)of both
pipes (SS & SD). I would like Mosbrucker to get the 6" DIP in before running the 12" SD so we can adjust CB 02N up
slightly if needed. Looks good Chris I think we have a plan.

Hi Bill,
Can you please let me know what IE you would be looking for in the 6 -inch SS line, where it would cross under the 12"SD pipe?
I think what I have seen in the past is to:
• Have both pipe sticks cross at the center of stick length,
• Concrete (CDF) bed the lower pipe (SS) just up to the top of pipe,
• Place a thin ethafoam pad or even a sheet of visqueen on top of the lower pipe at the pipe crossing point,
Concrete (CDF) bed the upper pipe, but keeping the two portions of CDF separate (ie not one big CDF block, but one bed and
one bridge).
Thanks,
Chris

I met with Marty/Olympic View this morning to discuss the option of running the SS under the new 12" SD with zero
clearance. He will discuss this with his supervisor but does not see a problem.
Chris we would need to run under the 12" SD with DIP (and possibly concrete encase under SD)and then change to 6" SS
plastic to pick up Holaday-Parks at the building. Looking at detail 1/C6.1 can we adjust CB 02N SW IE 393.30' up to help
create more room for the SS? This may also require an adjustment at the Kristar.
Easa can you combine your 3" & 6" inside the building to meet the IE 394.86' outside of the building? This would help
with fall to existing SS connection point.

This is going to be tight. I have added an as -built of detail 1/C6.1 showing existing 6" SS in relation to the new 12" SD.
The sewer needs to go over the top of the new 12" SD but we could hold it down to give us clearance at 394.30'as we
cross the top of the SD. This would give us 6 " of fall over 32'.
Easa the problem I see is with your 3" waste, can it come up to match the 6" waste IE of 394.86'? That would help.
Michael please add the new sketch to the RFI. Cheers

Yes please see attached PDF file of side sewer as -built and photo (and add to RFI). The 32 LF is the minimum fall length
@ 1'-2" (1.17') total fall. If you look at drawing C6.0 they have the connection at a Wye. We are around 3.6% of fall. We
would reduce the cover between the 6" pipe and bottom of footing to 4.25" .

I would like to submit this RFI to structural can you please advise if the below is appropriate and fill in the blank.
Can the requirement per 8/S3.00 for "Typical For Perpendicular Pipes Under Footings" regarding concrete backfill equal
to the width of the footing be reduced to ???.

Chris/Michael,
We are excavating the along grid E late tomorrow early Thursday. I will need to have Holaday-Parks stubbed below our
footing before we form. Can we get permission from the structural engineer to relax detail 8/S3.00 otherwise the pipe
will be lower than the side sewer IE.
Easa can you have your foreman call me as I would like to coordinate this work before next Thursday 22"d. Regards Bill

See attached sketch from our detailer. Elevation called out is from Vt Floor 398'-9".
We have a few design issues that we are working through with the design team that could drive the 6" main down
considerably. We are in the processing of confirming if AAV's at the island dental sink locations are acceptable. Also have
some questions on the backwater valve and how it will be accessed.
How soon will you need to an exact elevation? I will try and push for these items to be resolved so we are firm on the
elevation.

Easa,
We have located the existing side sewer which you will be connecting to once Mosbrucker extends to the
building. Looking at drawing C6.0 and A2.01 can you advise us where you would likeus to stop the sewer for
you to pick up the connection? Looking at drawing S2.01F the adjacent grade beam foundation is 24" thick and
we canb either leave the connection outside of the building or bring it into the building footprint. Drawing C2.0
shows IE at approximately 390.46' between the two MH structures which puts it at 8.29' below 1St floor slab.
We can bring this up closer to FF if you can give us an IE. Regards
Bill Bacon
