A super in Jersey City rolled his eyes at my schedule and it fixed my whole operation
About two years ago I was running a 40 unit gut rehab in Jersey City and I was pretty proud of my schedule. Had it in a spreadsheet, color coded, 14 tabs, the whole deal. The building super, this older guy named Ray who had been in that building 30 years, looked at it for about 10 seconds and said "this thing is fiction, you got no float anywhere." I was annoyed but he was right. I had every trade starting the day after the one before it ended, zero cushion, so one late drywall delivery blew up the next 6 weeks. I went back and rebuilt the whole thing with 2 days of float after each trade and I stopped stacking subs on top of each other in the same zone. First month after the change we still hit delays but nothing cascaded, and the punch list at the end dropped to 19 items versus the 60 or so I usually get on a job that size. Now I build float into the schedule from day one and I print it out for the super before we even start. Anybody here still running zero float schedules, or did you get humbled the same way I did?
My color coded masterpiece had 14 tabs and still fell apart in week 3, so you're not alone there. Ray sounds like the kind of guy who's seen every fancy schedule crumble and just waits for it. Two days of float after each trade is such a simple fix but it took me way too long to learn it.
