The Specifications for use on a project will be as defined in the ‘Project Execution Plan'. The specification requirements will be clarified in the Engineering Estimate or at the Preliminary Engineering Phase of the work. The Mechanical Engineer/Specialist will be responsible for maintenance, distribution, updating and/or generation of Specifications as required.

A number of WorleyParsons Technical Specifications exist. These Specifications are intended as minimum mandatory requirements to be complied with by Vendors. WorleyParsons Technical Specifications should be reviewed on a Project basis to determine applicability to a given Project. They may then be adopted ‘as is', or supplemented by a Project specific Addendum or revision. During the evaluation for Project suitability, should it become apparent that a particular revision may be required to the Corporate master Specification, the Mechanical Department head shall be notified.
