Lethabo Power Station – P&ID As Built Verification
Organization or Joint Venture Name:
Vereeniging, Free State, South Africa
The Scope of the project included the drawing of 804 Piping and Instrumentation Diagrams from “walk down” and “redline” information supplied by the client.
3DDraughting used the original vendor drawings to create a integrated set of drawings. The legacy drawings contained components in different systems and items could appear many time over many different drawings.
The first task was to source the latest set of drawings from a 180 000 site documents. The P&ID’s were then evaluated to determine the best layout and to ensure that each component is only shown once. These integrated P&ID’s were then sent to site for verification and “redline” markups were back draughted under a stringent quality control procedure.
All data was stored in a central database for further manipulation by the client.
