I am keen to hear from people who have assigned a Builder / PM to build parts or all of a project for them in the past (or at present). Or dealt with Trades directly...... What are the lessons learnt? Some examples: How differently would you have negotiated the details of your tender to avoid things such as variations? How would you have negotiated your timeline clauses? How would you have supervised progress / quality of works and organised schedule of payment? What would you have done differently to avoid small or large disputed and if they did happen how would you have handled it? If you have dealt mainly with tradies, what did you find useful in managing them?
