Example: new housing scheme, constructing 10 houses on separate plots. Brickwork can begin 5 days after the 20-day tasks of scaffolding being erected. However, brickwork can't finish until 5 days after scaffolding has finished being erected.

How do I link the start & finish of the brickwork to the start and finish dates of the scaffolding being put up? MSProject says I can't give one task 2 links to the same predecessor task.....

All help gratefully received..

  • If Brickwork can only start 5 days after Scaffolding completes, how is it possible for Brickwork to finish anything less than 5 days after Scaffolding completes?

  • Sorry - I wasn't clear. Brickwork can only start 5 days after scaffolding starts (not complete). Brickwork can only finish 5 days after scaffolding finishes.. I hope that's clearer

I would have 3 tasks.
1 Scafolding
2 Scafolding Complete (Milestone) linked to TID:1
3 Brickwork 1SS+20d, 2FF+5 days

That will give you what you want. As you say in project you can only have 1 link to the same predecessor task.

  • Thanks Richard. That'd work, although it's a little clumsy. I'm surprised MSP can't cope with this set of dependencies. It must crop up a lot.....I feel a suggestion to MS coming on........Thx again

  • Another spin - two milestone tasks (begin scaffolding and end scaffolding) which are SS and FF linked (respectively) to the scaffolding task, which is 20 days long. Then Brickwork linked appropriately. Commented Nov 25, 2015 at 20:53
