Hello all
Does anyone have a good (very detailed) detail design engineering schedule to have a look at? I am interested in how the activities and client review circulation period are structured. If someone says yes can you sent it to me at [email protected]
Thanks a lot.

DDR list all design documents that need to be produced in order to fullfill the engineering scope.
It is based on the deliverables list, but expanded to include all documents which will be issued for (internal and/or external) approval. For example, a deliverable might be "P&IDs", the DDR would list each P&ID as a seperate entry.
The DDR typically also tracks the status of the document through generation, approval steps, and issue for construction.
Often, it will also carry a weighting factor which, when combined with a pre-agreed percentage complete for each step in the documents life, give you the overall Engineering S-curve.
As previosuly stated, the DDR is a live document which changes throughout the engineering phase (you will only be able to estimate thre total number of P&IDs which will actually be required at the start of design, for example)
Thanks for the replies. Could you please tell me whats in a DDR? Is the DDR the same as the Deliverables list?
Dear Fernando,
You need to know the scope in your Engineering Contact at the Design stage. It will state the deliverable, and the time for each deliverable. Also, you need to dig up the review cycle by the client or any other entity.
Best Regards,

For me, Deliverable List, but its very difficult to define it from basic engineering to detailed engineering.
"DDR" is only a record, and its a running record, when to close it? who knows?
The contract & DDR (design document register) should give you everything you need.
Hi Gray
would you please abbreviate P&IDs
P&ID = Piping & Instrumentation Diagram. (Sometimes called Process & Instrumentation Diagram)
Most commonly used in the Oil & Gas industry.
