Practices by Discipline

This Practice is a guideline for developing Overall Electrical One-Line Diagrams (OEOLDs) by engineers and designers.  It covers the generation of new OEOLDs and may not apply to the revision of existing OEOLDs.This Practice applies to one-line diagrams that fit the definition of an OEOLD in Section 3. This Practice uses ANSI/IEEE 315 - IEEE Graphic Symbols for Electrical and Electronics Diagrams and IEEE C57.12.80 - IEEE Standard Terminology for Power and Distribution Transformer symbols.The main purpose of an OEOLD is to provide an initial view of the electrical system for use in early design discussions. Then, the OEOLD can be updated as the project develops and kept current to provide a reference document that shows a high level view of the overall electrical system. As a secondary purpose and function the symbols provided for use in a OEOLD are intended to provide basic information.  The basic information is shown in visible fields by default.  Many OEOLD symbols have hidden or invisible fields that provide extra information or details.  The invisible or hiddens fields can be changed to be visible based on owner requirements. This Practice can be applied to CAD systems used for developing OEOLDs, and is not supplier, hardware, or software specific. Electronic native files for the text, symbols, and cover sheets are available from PIP for use in CAD systems and have been developed in AutoCAD 2015. While the symbols can also be developed in Microstation DGN files, the functionality from AutoCAD may not be available in Microstation. Development of project-specific legend sheets is recommended using the PIP native files as a starting point. Additions and/or deletions are permitted to meet project requirements. Drawing borders and title blocks can be altered to be project specific.The guidelines in this Practice provide a balance between showing all data on OEOLDs and making OEOLDs legible and easy to read. Although this Practice describes major components in the electrical system, specific applications may require additional or alternative components. Determinations concerning fitness for purpose and matters of application of the Practice to a particular project or engineering situation should not be made solely on the information contained in this Practice.The OEOLD symbols included in the Appendices of this Practice are not intended to recommend specific design details or requirements. An example OEOLD is included to provide an illustration of how the elements of this Practice are combined into an OEOLD.

This Practice provides general guidelines for the format and content of Process Flow Diagrams (PFDs) for process and utility systems.This Practice covers the development of new PFDs and does not apply to existing PFDs developed before the adoption of this Practice.The Practice applies to all diagrams that fit the definition of a PFD in Section 3.This Practice can be applied to any CAD system used for developing PFDs and is not vendor, hardware, or software specific.Although this Practice provides general guidelines for the development of PFDs, individual applications may require differing approaches than those recommended in this Practice. Determinations concerning fitness for purpose and matters of application of the Practice to a particular project or engineering situation should not be made solely on the information contained in this Practice.Example PFDs in the Appendixes of this Practice are not intended to recommend specific design details or requirements, but are included to provide illustrations of various options available to the user.

This Practice describes the minimum requirements for a geotechnical engineering investigation including subsurface exploration, field and laboratory testing, analyses, and preparation of reports that present geotechnical engineering recommendations for design and construction. This Practice does not include requirements for an environmentally-related investigation or analysis.

This Practice describes the minimum requirements for the design of buildings. This Practice is intended to be used in conjunction with PIP ARC01016 - Building Data Sheet, PIP CVC01017 - Plant Site Data Sheet, and PIP STC01015 - Structural Design Criteria. This Practice does not apply to open or partially enclosed industrial structures.

This Practice is intended to be used in conjunction with PIP ARC01015 - Architectural and Building Utilities Design Criteria, PIP CVC01017 - Plant Site Data Sheets, and PIP STC01018 - Blast Resistant Building Design Criteria. These data sheets contain architectural, HVAC, electrical, fire protection, plumbing, and communication information that may be conveyed from the owner to the project design team or from the project design team leaders to the team design members. This data may be provided by the owner or developed by the project design team and approved by the owner.

This Practice provides structural design criteria for blast resistant buildings. This Practice describes the minimum requirements for the design of permanent (non-temporary) blast resistant buildings including requirements for selection of structural systems, analysis methods, and design of ancillary items such as doors and openings. This Practice also contains design criteria for non-structural items (e.g., suspended architectural or electrical items, HVAC ductwork, etc.) that could pose a hazard to the occupants of blast resistant buildings.
