ACEP ID:
Intergraph Smart Instrumentation—often referred to as SPI or Intools—is the industry-standard software for instrumentation engineering and design. Developed by Hexagon PPM (formerly Intergraph), it provides a single, central database to manage the entire lifecycle of an instrumentation system, from initial design through to decommissioning.
Pros: Unmatched data consistency, powerful automation, industry standard. Cons: High cost, steep learning curve, requires dedicated administration.
