About your Project
As a note, if your project has an activity that is noisy or disruptive try to do that work first thing before your owner becomes project tired! Later, he will get tired of the project and become more difficult with dust or noise.
When your subs make mistakes there is no need to tell your customer or maybe not even the architect. Because we hired them we must take some responsibility for their mistakes. They are somewhat like our own employees, so keep it confidential.
Remember the biggest reason projects fail is lack of timely information. Your job is to push for timely information to get issues resolved.
