Warning: A 'simple' retrofit in a 60s office building turned into a 3-day nightmare

Last week I got called to install a new panel in a downtown office. The old wiring was a mess of cloth-covered stuff, and the previous guy had just twisted and taped everything. I spent a full day just mapping it out, and on day two I found a whole zone was backfeeding through a junction box in the ceiling. The building manager kept saying 'it was working fine before,' but it was a fire waiting to happen. Ended up running all new wire for that section and billing for the extra time. Anyone else run into these hidden disasters on 'easy' retrofits?

Ugh, classic. Always budget double the time.

Learned that the hard way last week. Just started adding a buffer for every single step now.

Used to think adding buffer time was just being lazy. Then I got burned trying to fix a simple bug before a demo. Took three hours instead of one and I looked like a fool. Now I pad everything, like @ben_nguyen said. That extra hour for a meeting or even just to send an email saves my sanity every single day.
