In my early days as a carpenter, I worked on many job sites that were in chaos. The hvac, plumbing, and electrical subs were tripping over each other, and the drywall contractor pulled up ready to hang rock before the building inspector had signed off on the project. This "show up when you can" form of construction management was frustrating for everyone on the job. When I became responsible for project schedules, I learned from the mistakes of my previous employers and looked for ways to avoid these problems. I started to think about the project schedule in the same way I think about the estimate. There is no way to give a client a cost estimate
