How much detailed is DETAIL Engineering?

Similarly to realizing where BASIC Engineering stops (see corresponding post) it’s interesting to realize that DETAIL Engineering does not produce all execution drawings: some are left to the construction contractor to develop.

  • 10 GB for database size.
