Same situation here. When I was in construction we would put a 2 stop Esco 886 Holeless in 12-14 working days. That was lightening speed at the time. We now have a mod that can be done in 2 weekends! Its crazy but the trend is not quality but quantity. Until the building owners get wind of it and care it will continue.
2 stop hydros are now thought to take no longer than 3-4 working days, some actually achieve that.
