Typically, the materials engineer specifies the requirements for a piping specification in the form of what is commonly referred to as a 'human spec'. It is your responsibility as the piping specification writer to interpret the human spec and transfer that knowledge into a form that is recognized by a Smart 3D Piping Specification.

The following guidelines for interpreting a human spec are presented in terms of addressing the requirements of a specific example of a human spec. For the sake of simplifying this to a discussion, it is assumed that the following pre-requisites have been addressed.

  • All piping parts required by the piping spec already exist in the piping catalog. However, if an additional piping part is required, you can create the piping part during the spec creation.

  • All applicable select list values have been created. However, if an additional select list value is required, you can easily add a new value during the spec creation.

We recommend that you review the Tools > Options in the Catalog task, and to customize these options, as required, to meet the requirements of the piping spec to be created. When reviewing the Options dialog box:

  • On the Piping Specifications tab:

    • Select a default industry practice.

    • We recommend that you enable the commodity code builder option, when the commodity code can be formatted, for ease in the selection of piping parts.

    • We recommend that you select the Create material description by rule option.

    • Set the Include schedule with contractor commodity code option as needed.

    • We recommend that you select the Verify specification data on entry option.

    • We recommend that you select Based on pipe stock and branch nipples in piping commodity filter for determining branch and header sizes.

    • Select how you want to view piping specification notes.

  • On the Piping Specification Units and Piping Catalog Units tabs, set the units of measurement.

  • On the Short Codes tab, customize the permissible short codes, as required. We recommend that you do not use end preparations in short codes. You should recognize the requirement for functional short codes (generic short codes).

    • We recommend that 'Check Valve' be used, whereas the human spec has used 'Lift Check' and 'Swing Check' for different size ranges.

    • We recommend that 'Vent/Drain Valve' and 'Instrument Root Valve' be used as the function of the valve rather than specifying the type of valve. This provides consistency for the piping designer in situations where the type of vent/drain valve might differ between two piping specs.

    • We recommend that '90 Degree Direction Change' and '45 Degree Direction Change' be used rather than 'Elbow' or 'Pipe Bend'. This provides consistency for the piping designer in situations where the type of direction change fitting might differ on the basis of size within the same piping spec or between two piping specs.

    • We recommend that 'Concentric Size Change' and 'Eccentric Size Change' be used as the type of offset from the size reduction rather than specifying the type of in-line reducing fitting. This provides consistency for the piping designer in situations where the type of size reduction fitting might differ on the basis of size within the same piping spec.
