Smart Sprinklers application for Revit® uses text files in which diameter of pipes has a dependence on a number of fed sprinklers.
Usually we use NFPA, AS or ISO standards for pre-calculation of diameters. This looks like this:
Here, in this table you can see range pipes, layout and maximum number of sprinklers fed. According these values, you can pre-calculate diameter of a pipe.
As I have already mentioned – Smart Sprinklers uses text files to pre-calculate diameters. This text file looks exactly the same as NFPA, AS or ISO standard’s tables:
If I compare two tables (one from ISO standard and the other from BIM solution Smart Sprinkler) I will see similarity:
- The first column of Smart Sprinklers text table refers to Range pipe description:
- 2 – Range at remote end of all distribution pipes – last 2 ranges
- 3 – Last 3 ranges
- 1 – Last range
- -1 – All other range pipes
- Second column of Smart Sprinkler text table refers to Layout position:
- 2 – 2-end layouts
- 3 – 3-end layouts
- -1 – All other layouts
- Third column of Smart Sprinklers text table refers to connection position:
- Side – for side connection
- Center – for center connections
- Fourth column of Smart Sprinklers text table refers to Diameters of range pipes;
- Fifth column of Smart Sprinklers text table refers to maximum number of fed sprinklers.
Text file should be placed on your work station so that it could be seen in Smart Sprinklers solution:
Smart Sprinklers users can create their own text tables and use their own standards to pre-calculate range pipe diameters, considering they made the text tables and standards according to the workflow described in this post.
