The Standard applies to new installations as well as alterations, additions or repairs to existing installations. What interested me the most is that many hydraulic designers have told me I dont use Barrie Smith as his results oversize the pipework but you can see in the comparison that Barrie Smith and AS3500 are almost identical, with AS3500 actuallyreturning probable simultaneous flow rates higher than that ofthe Blue Book fromaround the 22 fixture unit mark. Were picking up the calculated fixture units from our pipework and multiplying it back out by our 3.5x multiplier from my previous postto give us our actual AS3500 compliant fixture units. Not to mention, with the AS3500 pipe sizing work(around)flow that I posted last week, the flow rates still dont quite match up due to the IPC vs AS3500 conversion factor. Is assigned a fixture-unit rating of four inch drain handle assigned a fixture-unit rating of four how! Heading back to our second (green) step, theList.FilterByBoolMask node feeds into anotherElement.GetParameterValueByName node.

For the purpose of the demonstration, Ive created all the distribution pipework at 50mm. Its frequently touted as the best method to model a facade made from old chairs, but did you know that Dynamo can be used for actually useful things too? If youre using out of the box (OOTB) Revit families, check the loading units (which are called fixture units in Revit) and check that they match the requirements of AS/NZS3500.

There are six main systems of sanitary plumbing. It applies to new installations as well as alterations, additions or repairs to existing installations. e. I have a Excel sheet where I transcribed table 48 from the Blue Book, filling that sheet out with our fixture count, we can see that if were only taking into account velocity requirements when sizing our pipework, 32 diameter is quite oversized even for 15 toilets and that 25 or even 20 diameter would be a more acceptable size. Give it a go yourself, once the Dynamo portion is humming along your return of investment is incrediblyquick. Wireless Access Point With Ethernet Ports, I have since written customised code to cater for Australian Standard pipe sizing in Revit so I no longer use this method in the post, however my original spreadsheet, the dynamo graph and now my Revit addin all use the Barrie Smith fixture unit conversion table (table 48) and all sizing is verified with the data contained within the Barrie Smith book on tables 2-7 for cold water and tables 8-13 for hot water. Upgrading to a 6-inch pipe with the same grade will allow you to load the pipe with 840 drainage fixture units. A good set of families are the building blocks of good pipe sizing results.
