When inputting data through Dynamo, Revit doesnt know that youre inputting metric figures. So the IPC probable simultaneous flow rates far exceed that of the Australian Standards, but is there any correlation between the two? When working through a family, you not only have to take into consideration the 3D elements, but parameters as well. The answer is always no, not because I dont want to share, but because I would rather people learn and understand for themselves rather than taking the easy way of grabbing something from the internet. If you like, you can even copy/monitor the architects fixtures and then map them inside your model to your engineering fixtures. After all, doing it properly takes far too long, so just go with your gut and prove your design with actual calculations later, but only if someone questions it down the track. To the inexperienced , in AS/NZS 3500.2:2003 provides the fixture-unit ratings for plumbing fixtures ratings, And vent most plumbing systems consist of what 's known as DWV, which is drain water.

Our last fork from the second (green) step is to calculate our head loss for our section of pipework. You can use any multiplier to suit your needs, but after extensive testing, a multiplier of 3.5 gives consistent results across many different designs where I have used Revit to size AS3500 compliant pipework. Take the following example, comparing a simple Excel formula to its Revit equivelent, =((AS3500_PSD / 1 L/s) * 0.001) / ((0.7854 * Diameter ^ 2 * 0.001) / 1 m) / 1000. 6.2 FIXTURE UNIT RATINGS 67 - 6.3 TRAPPING OF FIXTURES AND APPLIANCES 67 - 6.3.1 General 67 - 6.3.2 Water seal 67 - 6.3.3 Location of traps 67 . 4.8 FIXTURE UNIT RATINGS . general design requirements for sanitary plumbing systems 6.1 scope of section 6.2 fixture unit ratings 6.3 trapping of fixtures and appliances 6.4 graded discharge pipes 6.5 junctions in stacks 6.6 connections near . 6.2 Fixture Unit Ratings 6.3 Venting For Fixtures 6.4 Trapping Of Fixtures And Appliances 6.5 Graded Discharge Pipes 6.6 Junctions In Stacks 6.7 Connections Near Base Of Stacks 6.8 Vents 6.9 Air Admittance Valves 6.10 Pressure Attenuators Section 7 Greywater Plumbing And Drainage Systems 7.1 Scope Of Section 7.2 General 7.3 Material And Products 710.1 Maximum fixture unit load Calculating fixture units and installing plumbing can be difficult to the inexperienced. test. The output of the python node then feeds into a math divide node and we divide our flow rate figures by 28.317 and pushes the result to a flow based parameter that Ive named AS3500_PSD. Comparing extracts of both the IPC and AS3500, we can start to analyse the differences between the two standards. Referring back to the Blue Book, we can see that 32mm gives a velocity of 1.482m/s which falls within our AS3500 range. Illustrations used in this Standard are diagrammatic only and have been chosen without prejudice. Know if we were sizing a discharge pipe to connect a basin and bath joint Zealand! The Barrie Smith lookup was the most difficult part as it required custom python code to perform the lookup. 6.5 Trapping of fixtures and . Excel, Dynamo and Revit can calculate this quite quickly but the power of Revit is that you dont have to manually enter any data, you just model the piping and connect the system. This system requires the use of an aerator junction fitting (a proprietary junction fitting) to connect discharge pipes at each floor level that receives a soil or waste discharge, and a de-aerator at the base of the stack. Or a few fixtures standard was prepared by joint Technical Committee WS-014, plumbing and Drainage basin and bath handle. For example, changes in lifestyle and flexible work hours .

The Aged Standards Review is one of the ways in which Standards Australia gives effect to that commitment Figure. I had the pleasure tospeak about this topic at the 2016 Revit Technology Conference (RTC) back in May where I demonstrated a simple workflow that sizes domestic water pipework to AS3500 compliant sizes. Just like AS/NZS3500 and Barrie Smith, the IPC provides a table that can be referenced to convert loading units (fixture units in Revit) to a probable simultaneous flow. This gives a set oftrue and false results for all of theselected elements, which in this case is our pipework. Two Sentence Stories With A Twist, Each pipe connected to the stack that serves more than one fixture is referred to as a common discharge pipe. Yes, this is how I spend my nights in hotels when travelling for work. I decided to use the KG Martin method for sizing (from the CSIRO Experimental Building Notes 1978). You simply input the data you would normally enter into a roof drainage calculation sheet into the Revit family, I also added a few more inputs to allow further control over the family. Upgrading to a 6-inch pipe with the same grade will allow you to load the pipe with 840 drainage fixture units. Are comprehensive and easy to understand would be important to know if we were sizing discharge. A relief vent is installed if one or more floor levels exist between the connection of the highest and lowest fixtures. What resulted in an excellent parametric family had absolutely nothing that I could schedule out. If I change the cold water connection to use fixture units, and manually enter 5 fixture units, the incoming pipework is reduced to 20mm. Ispeak with a lot of guys in MEP locally and they give me the impression that they thinkpipe sizing is some kind of dark art, in actual fact its not that difficult at all.
