Specifications consist of database items which define which type of pipe, fittings, valves, hangers, etc., will be used in a piping system.
The Specification section will take approximately 2 hours.
Next, you will manipulate the specification to use the exact specifications your company will use on a daily basis. This includes setting up the type of Pipe, Fittings, Joints, Valves, Flanges, Hanger Types, Hanger Spacing, Insulation Thickness, Specialties Items and Bookmarks.
The dots only appear on single items: pipe, valves, etc. On fittings, there are many items represented and they may have different sizes possible.
Change the fittings so they are accurate for our Job.
Change the Valves so they are accurate for our Job.
To see more items on this Spec screen, click the down arrow on the bottom right side of the screen. The screen scrolls down.
Change the Flanges so they are accurate for our Job.
Change all the Hanger components so they are accurate for our Job.
Keep in mind you can have up to 7 hangers per Specification (including Riser Clamps). In addition, the hanger that is first (at the top) of the “Hanger†section in the spec will be the default hanger that shows up in the Takeoff screen. If the job is an all concrete job, you may want to move that to the top using the Shift Command. This will eliminate extra clicking when you get to Takeoff.
Notice as you scroll down the specification screen, you can see the variety of hangers that are available.
Double click on a hanger. You can now verify that the selection is correct. All of the components shown will be calculated for each hanger of this type that is being used in Takeoff.
Notice the dot next to “Insulation Size” is selected. This means the hanger is sized to include the pipe diameter plus insulation thickness (x2). If Pipe Size is selected, the hanger is sized to only pipe diameter (no insulation).
Verify that the insulation thickness is correct so that the hanger size and sleeves are calculated correctly. (This is required for the proper over sizing of hangers.) Click to return to the Spec screen.
You can add a new hanger.
Scroll down to view more items. Look at the Hanger Spacing along the left-hand column.
NOTE: If hanger spacing is not selected for a specific size range, then the system cannot calculate hangers automatically.NOTE: If hanger spacing is not selected for a specific size range, then the system cannot calculate hangers automatically.
Change the insulation thickness so it is accurate for your Job.
Notice on the following screen that the 1″ Insulation is specified from ¼” up to 1½” pipe diameter. (This is shown by the gray boxes.)
For most contractors, the insulation thickness is used so that the system will oversize hangers and sleeves automatically for you. If you self-perform your pipe insulation, you may want to select an insulation group and component for your spec. You will be generating a material cost and installation hours for doing pipe insulation.
You need to create the group in the database.You need to create the group in the database.
When you select at the top of the Spec screen, a pulldown list appears. You have a choice to add any group of items: Pipe, Fitting, Valve, etc.When you select at the top of the Spec screen, a pulldown list appears. You have a choice to add any group of items: Pipe, Fitting, Valve, etc.
To see Specialty items, scroll down on the Spec Screen. In specialties, you’ll see such items as Dielectric Unions, Nipples, Sleeves, and O-lets. Again, select the items for the size ranges that each item is to be available (used for).
We’ve expanded a spec beyond pipe, valves, and fittings. You can assign a bookmark to a specific spec. You'll see how this applies in Takeoff.
NOTE: No other automatically generated items “come along” with bookmarks.
Once you are happy with the changes you made to the specification, click .
