There's much experience and knowledge around here that I'd like to tap into so we can all share our experiences (good or bad) in one place.
Just wondering some of the things for those who have finished or are close to finishing their OB project that you would have changed had you known then what you know now.
eg -
1 - Get a professional estimator prior to starting
2 - What design ideas you wish you had included
3 - Things you wish you had not bothered with
4 - Cost saving tips eg Importing fittings direct from O/S
5 - Time saving tips for co-ordiniating trades
6 - Things to kepe a close eye on
and so on
Anyway hit me with your best (or worst) and thanks for sharing
