To understand Revit MEP Pipe Types, imagine them from the perspective of the installer. The Pipe Type is related to the material and style of fitting used. For instance, both chilled and hot water mechanical pipes, 3″in diameter and under, are commonly constructed from copper with soldered or brazed sweat joint fittings. This should be the basis of your Pipe Type.
To modify and create new system pipes, in the Project Browser choose Families Pipes Pipe Types and then right-click the Standard pipe. Select Duplicate. This will create the additional Pipe Types you will need for your project. Next, right-click the duplicated Pipe Types and rename them to the Pipe Type you require. It is preferable to rename them to the pipe material
type (see Figure 11.1).
Avoid naming your Pipe Types as system type names (such as hot water supply pipe). This makes it harder if you use your model for an integrated project delivery for which you are partnered with a general contractor and mechanical subcontractors. The contractors will want to take the information and use as much of it for shop drawings as possible. This is where the Iin BIM becomes more than a catchphrase. The more accurate the information about the material, fittings, and so on, the more accurate the material takeoffs will become for pricing and budgeting purposes.
Now that you have your Pipe Types created, you will want to change some of the parameter options. First, right-click the Pipe Type you want to edit and select Type Properties. This opens the Pipe Type parameters. With regard to careful space planning, the accurate selection of fittings is the most important and most time-consuming task when setting up your Pipe Type.
This is addressed in the following subsection.
Under Mechanical, you will find Material, Connection Type, and Class parameters. Change
these settings to the appropriate types (see Figure 11.2).
