Microsoft Project Start & Finish Date being a Duration from Project Commencement Date RRS feed

  • Question

  • I need to schedule ~92 tasks which have a start and finish time based on a number of days from the Project Commencement Date which is currently not known.

    E.g.: Bridge A09 start 101 days from Date of Contract and finish 109 days from Date of Contract. Therefore a duration of 9 days.

    Can this be entered into Microsoft Project so that when the Commencement Date is finalised and entered all the tasks will also alter their start and finish dates while maintaining the duration between them.

    The days are calendar days not work days.

    Please advise, thanks.

  • Hi Ian,

    It is indeed possible, and I would say that it is a best practice in scheduling. In MS Project ribbon, "project" tab, "project information", you can set the project start date.

    Then schedule your 92 tasks with dependencies (links) and not constraints on the start/finish dates. Meaning that you have to create links between tasks and enter a duration, no start date which will create constraints. You should have no "calendar" icons in the indicator column.

    This is the condition for getting what you need : as soon as you know the project start date, just update it in the project information and your entire project will be moved accordingly, keeping the dependencies and durations.


    Hope this helps,
