Instrumentation (SPI)

Produce instrumentation deliverables using SmartPlant Instrumentation (SPI) for accurate data management and project consistency.

Service Overview

At Engineering Design Services, our Instrumentation (SPI) services provide structured, data-driven engineering support for the design, specification, and management of instrumentation systems. Using SmartPlant Instrumentation (SPI), we create a centralized, intelligent database that connects instrument design data across all project phases, from concept through construction and into operations.


Our team works closely with clients to develop complete instrumentation deliverables including instrument indexes, data sheets, loop diagrams, and I/O management. We ensure all instrumentation data is accurate, traceable, and aligned across process, electrical, and control system disciplines.


From new facility design to plant expansions and system upgrades, we ensure instrumentation information is consistent, maintainable, and fully integrated with project execution workflows.


By combining instrumentation engineering expertise with SPI database management, we deliver solutions that reduce design errors, improve coordination, and support long-term operational efficiency.


Whether supporting greenfield projects, brownfield modifications, or facility modernization, our team delivers SPI-based instrumentation solutions built for accuracy, reliability, and lifecycle performance.
