Manual Pipe Routing Revit mep

Manual routing of piping is the next method. When routing, manually start the piping run at the elevation that you know will most likely be out of the way of other disciplines. Use the following steps to set up and place mechanical equipment, create a hydronic supply and return, and manually route pipe to all pieces of equipment:
1. Open the Ch11_Project.rvtfile found at www.sybex.com/go/masteringrevitmep2012.

2. One of the best practices is for the architectural model to be linked into the mechanical model. Download the model C11_base.rvtfile found at www.sybex.com/go/masteringrevitmep2012.
3. Choose Insert Revit Links, select the directory into which you downloaded the Revit base, select Auto – Origin To Origin, and then select Open. By selecting Origin To Origin, you are assured that the model will be properly located (see Figure 11.12). Open the default 3D view, {3D}, to review the Architectural model.

To improve productivity in piping layouts, make sure to create and maintain project templates that contain your company standards. Properly created project templates ensure that everyone in your firm is on the same page when creating mechanical piping systems. For more information on how to create project templates from existing projects, refer to Chapter 2, “Creating an Effective Project Template.”
4. Open the NORTH Elevation and, from the Collaborate tab, select the Copy/Monitor tool.
When prompted, select the link file and then select the linked files for Level 1 and Level 2.
Click the Finish button.

5. From the view tab, choose Plan Views Floor Plan, and create views for Level 1 and Level 2. Open Level 1.
6. Choose Insert Load Family Imperial Library Mechanical Components Air-Side Components Heat Pumps. Select WSHP – Horizontal.rfaand then select Open (see Figure 11.13).

7. Choose Home Mechanical Equipment, and start placing the water source heat pumps (type 006) into each room. After you have placed all the heat pumps into the model, rightclick the water source heat pump you first spotted and choose All Instances Visible In View. Then, from the Properties dialog box, select Offset and change the offset to 9′-0″(2750 mm). This will allow you to set the correct elevation of equipment (see Figure 11.14).csv4
8. Your system will require a boiler and a closed-circuit cooling tower. Choose Insert Load Family Imperial Library Mechanical Components Water-Side Components Boilers. Select Boiler.rfaand then select Open. Repeat the process to load the Cooling
Tower – Closed Circuit – Counterflow – 37-211 MBH.rfafile from the Cooling Tower directory located in Water-Side Components. After these are located in the project, place them into the appropriate locations, as shown in Figure 11.15.

9. Next you will need a centrifugal pump. Choose Insert Load Family Imperial Library Mechanical Components Water-Side Components Pumps. Select Centrifugal Pump -Horizontal.rfaand then select Open. Place the pump where you want it to be located in the mechanical room (see Figure 11.16).

10. You are now in a position to start routing piping. Route your mains first so you can make sure that most of the piping will fit before connecting all the branches to the mains. Select the proper piping material before starting your layout. This will help if you need to do a quantity takeoff for budgeting purposes. To route your pipe, choose Home Pipe. Change the offset to 8′-6″(2600 mm) and pipe size to 2″(50 mm), and route piping mains
in the corridors and into the mechanical room (see Figure 11.17).

11. Before you start connecting piping, you will need to make sure that your mechanical equipment is set up for both hydronic supply and return systems. To do this, select one of the pieces of mechanical equipment, and then go to Modify | Mechanical Equipment Piping and select Create Hydronic Return System (see Figure 11.18).

12. After you have selected the hydronic return, go to the Piping Systems tab, select Edit System, and edit the Hydronic Return system name. Then select Add To System, and select all mechanical equipment that contains Hydronic Return connections. Repeat with Hydronic Supply (see Figure 11.19).

13. Cutting sections when routing piping can really improve the coordination success of your Revit model. To route piping, choose Home Pipe Modify Place Pipe, and be sure to select Connect Into (see Figure 11.20).

14. Repeat steps 6 through 13 for all your piping systems. Taking a few minutes to review any clashes between the structure, mechanical, and architectural models can really cut down on potential field conflicts. After you have coordinated with other services/structure and verified your layout, the layout will be complete
