Project Execution Plan (Universally Applicable)

Abstract ↓

​This practice defines the purpose and requirements of a Project Execution Plan (PEP) document. The practice provides key considerations to the development of the PEP document and standardized guidance to ensure consistency, clarity, and alignment in documenting how projects will be executed, monitored, and controlled throughout their lifecycle. The designation “Project,” as delineated within this document, encompasses a spectrum of work scopes that may be as small as engagement of a third-party entity for completing a small design study, or may be as large as executing complete engineering, procurement, and construction (EPC) activities for a greenfield facility. This practice has been developed considering a PEP for a large, greenfield EPC project, spanning early front-end loading (FEL) phases through commissioning. This practice is not intended to provide the format, structure, or style for the development of the PEP but provides considerations to customize and use as project needs dictate. ​​

Hygienic Process Seat Valve Specification (Universally Applicable)

Abstract ↓

​This Practice provides the minimum requirements for the specification of mechanical and controls functions, design and manufacturing of seat valves in hygienic processes. Mix-proof valve packaged systems may include a broad range of designs for process and Clean-in-Place (CIP) applications. This Practice is intended to address basic requirements that are typical for typical single seat and mix-proof valves. The purchaser shall ensure that specifications are invoked and provided for specific applications that exceed the scope of this Practice. The purchaser may also provide data sheets, P&IDs, process data, and any other supplemental specifications to define the requirements for specific packaged equipment. For the purposes of this practice, “Hygienic,” “Process,” or “Hygienic Process” refers to all hygienic processes for Food/Beverage/Consumer and Current Good Manufacturing Practices (CGMP) or other products requiring a clean design.​
