as late as possible

Dear Raed

This logic only works if you have ensured there are no "open" activities. Having a missing link would result in these activities being measured from the end of the entire project.

I would advise against.

If the engineering task is just 1 day late, it will delay construction. And since engineering activities are notoriously difficult to predict and control, this is quite a risky approach.

Hi Gary

I disagree.

Having engineering tasks linked to construction by ALAP gives the correct delivery date for the design.

If the construction slips then the designers have more time.

If the design slips then the construction is delayed.

I would usually put a 5 day buffer on the link and have the "Traffic Lights" set to 5 days.

Hi Mike,

I would say using ALAP gives the latest delivery date for the design deliverable, not the correct one.

I prefer to plan engineering tasks to happen as early as possible (allowing for limited engineering resources, and prioritised on free float). They often slip, but this way you have the max amount of buffer before slippage becomes an issue.

Another point to note is that if you are using ALAP, be sure you have allowed enough time for any procurement required before construction can commence.

Cheers,

Hi,

I use ALAP for engineering and may input 1 month buffer just to establish the possible start. After establishing the start of engineering, either use a lag from the Engineering Start or Start Constraint then remove ALAP.

This will give Tech Dept time to prepare and a buffer before construction.
