SPU Design Checklist

  • This checklist shows the expected level of care and standard deliverables needed to produce a quality pipeline project. It may be useful for other types of SPU engineering design projects. The list is not exhaustive and is not intended to substitute for your engineering judgment. Note: On many projects, deliverables listed during 30% design should have started earlier during preliminary engineering.
    The checklist is organized into six phases:
    1. Scoping
    2. 30% design
    3. 60% design
    4. 90% design
    5. Bid documents
    6. Construction
    More detailed follow-up questions and lists are associated with most major checklist questions. Potentially useful contacts/links/documents are noted as Resource(s).
    Minimum deliverables are shown in red.
    Coordination points with physical security discipline are shown in green.
    Coordination points with electrical design are shown in brown.
