Coordination of specifications for process control systems with project specifications for other disciplines, including process equipment, is essential. For example, implementation of system-wide uniformity in requirements for packaged systems (pumps, screens, centrifuges, and drives) requires either specific reference to instrumentation requirements or repeating them in equipment specifications. To reduce the risk of errors when specifying devices in more than one location, it is strongly recommended that requirements be written in one place only. As such, the reader is encouraged to include text within the other discipline section to meet the requirements of instrumentation specification. While simplifying paperwork for the contractor, listing requirements for devices and control panel details in the equipment specification requires careful replication to ensure device matching.
