Is it better practice to summarise long lead items in one summary bar at the top or bottom of the chart, separated from the construction activities or amongst the construction activities?
In my experience, putting the lead ins as line items immediately above the installation activity seems to throw some colleagaues as they misinterpret the procurement durations as being part of the on site durations for say the fit out of a particular unit; while others fail to pick up the long lead items at all if they are separated on the programme page.
