    Hi All

    The original post was:

    There are four different techniques to do the delay analysis

    1-As-Planned Vs As-Built
    Best used when Sub-Contract work is compressed between other trades.
    2-Impacted As-Planned
    Used for on-going work
    3-Collapsed As-Built
    Completely unreliable - don’t even go there.
    4-Time Impact Analysis
    Best for forensic analysis but must have accurate As Buit data to be effective.

    I hope this is clear

    Best regards
