1. General

Site works are rarely completed and turned over to the client as a single entity. More usually this is achieved in discrete stages based on functional systems or geographical zones or by complete buildings as the case may be. Ideally the manner in which this is to be organized should be defined before the work on site starts, with specific requirements being incorporated into the Construction Procedure & Execution Manual and into the construction subcontracts.

Such an arrangement enables all parties to know from the beginning their roles in achieving a smooth evolution from construction, through punchlisting and on to turnover. Should turnover stages not being defined at the time the site is opened, the Project Construction Manager shall liaise with the client and the relevant Company departments to clarify this situation as early as possible during the site works.

2 Turnover Stages by Functional Systems

Turnover stages for a process plant are normally defined in terms of functional systems covering both the process units themselves and the offsites and utilities. Each system is defined by means of (where applicable):

  • A marked-up process and instrumentation diagram(s) (P&ID).
  • A list of piping isometric drawings.
  • A list of mechanical equipment.
  • A list of instruments.
  • A list of electrical schematic diagrams.
  • A list of instrument loop diagrams.

For the sake of completeness, infrastructure items e.g. roads, piperacks, buildings, fences, concrete structures, etc. can be assimilated into the list of functional systems (in that for example a piperack is a "pipe support system" or the roads are a "vehicle access system", etc.). This enables each and every item of works to be included in one or other of the turnover packages.
