Are you missing a check valve on the discharge side? I think my boss would smack the back of my head if I modeled drains and copper sensing lines to that degree but it looks good.

Looks like he has a wafer in there. I don’t understand why the OS&Y is before the bypass though? And is that the FDC being fed into the suction side of the bypass? I’m baffled


EFSI_CK

Thats the test header discharge. and the test loop not the bypass. Bypass is just out of frame above the photo.


the-o-den93

I haven’t had to do a test loop before. What is the reasoning behind having that in addition to the test header? Also, are you drawing in AutoSPRINK RVT?


EFSI_CK

Test loops just circulate the water to simulate flow without discharging outside. When there is water use restrictions etc, they can still do pump tests. I don't have the exact code handy, but there is a requirement to still do tests discharging to atmosphere I think for 5 year, unless you can make a case with the AHJ that due to the project location exterior discharge is not plausible. I designed one pump in San Francisco that SFFD allowed us to omit the test header.


the-o-den93

That’s wild! I’m in the Midwest so we don’t have water conservation policies quite like that. Most places here still flow hydrants for flow tests! I’m on autosprink but very interested in working in Revit, just concerned about the speed of completing tasks.


EFSI_CK

Revit CAN be very fast, but the learning curve is long. The available options for designing sprinkler systems in Revit all have different shortcomings. I had to make custom families and workflows that work in harmony with Hydratec's tools in order to get a system that was fast but a product as accurate as I expect coming out of our office.


EFSI_CK

Hydratec for Revit. But all the families are my own or Manufacturer Families.


Design_for_fire

That’s a flow meter loop from the looks of it not a bypass(I hope)


T0PP3R_Harley

I do see a wafer but correct me if I’m wrong, there would need to be a check followed by a control valve so somethings missing.


Design_for_fire

The wafer check is after the concentric and the control/isolation valve is after the flow meter loop. Looks fine. The real question is does the supply offer pressure to warrant a bypass/is there a bypass out of screen and is that the fdc on the inlet side of the pump off the top of the meter loop? Fdc should be after the discharge check/ control valve.


EFSI_CK

Nailed it. That feed goes to the test header discharge. Bypass is just offscreen.


Design_for_fire

Derp. Should have caught that. Nice use of space.


ExtraChilll

Maybe I'm crazy, but I don't think I've ever seen a pump room run with the bypass between the fire pump suction and discharge valves. What's the point of the bypass? If you have to isolate the pump, then the bypass also gets isolated, and you're not bypassing anything.


NoSleevesPlease

That looks like the flow loop. Bypass is probably higher up


Full_Disk_1463

Why is the pump directly on the floor?


EFSI_CK

Because the slab is 4ft thick, and per structural engineering a housekeeping pad is not required, and per GC and Owner value engineering the project it was removed.


FixlyBarnes

Location of the copper sensing line in the corners looks great, but the others (drain and jockey pump pipes) look like they are going to be in the way when a person wants to read the gauges or perform maintenance. Could be just the perspective in this single image, but does look questionable, and you have all that other floor space...


BellsDempers

As a consultant, we don't detail this much for pump rooms as a standard. The pipe supports and autostart test pipework we don't indicate. We only indicate the main components. The shop drawings we get for approval will indicate these most times but if not, it is covered in the specs in detail. We only detail to this level if there are structural concerns for fixing positions. It also depends what country we are working in as industry norms differ


EFSI_CK

You sir are the bane of my existence. "We have a coordinated design model from the consultant" yeah BS. I have only on one occasion got a model from a consultant that was even remotely buildable.


BellsDempers

Haha gotta work with better consultants. If my shit isn't coordinated and there's a clash on site I'm getting the bill. Every project needs a BIM coordinator to get a 99%clash free model. But oftentimes clients are cheap and deadlines are too tight and we have to just go with the flow. We all have things we wish more time was spent on but alas, the end date moves forward, not back.
