I've read (forget the source now) that one of the reasons Titanic took longer to build was because there was no rush after Olympic was built. The wanted to get Olympic out as soon as possible for various reasons. The marketing and all that of the new class of ships. It was more Olympic was built quicker than Titanic was built was slower. If you want I can go hunt for the source of that. CheersI still see it was not necessary to spend so much on that type of gantry, and to question the efficiency as building the Titanic hull took nearly four months longer than Olympic hull which at the time, they were both the same size.
