duration for civil engieering design

Have you submit a search in "Prod-Rates"? However, production rate on engineering deisgn, too hard.

Try to ask to the engineering company.
Or if You are workign in an engineering company call a meeting to discuss the document register and the weight (manhrs)for each deliverables (drawing, calculation report, etc ...).

It is the best way

The list could be very long Tom,

But Basically,
The hrs required will be vary depend on the level of Engineering Stage (Preliminary Study, FEED, EPCI Detail Design, etc)
For Drawing also there’s one additional factor, whether the Project use advance 3D Modelling Software (PDS, PDMS etc) or only produce drawings on 2D basis.

But from my experience, one standard jacket (which basically only consists of structural steel) may expend about 25-40 mhrs, during Engineering detail design stage and by using generic drawing production methods (no 3D modelling in advance). That hours comprise of 10-15 % Engineer hrs, 20-30 %Lead/Senior Designer (ie : checker) hrs, and the rest are for the designer/draughtsman.

Note that we will required additional hrs for more specific/detail drawing (ie : topsides, major equipment, etc)
