    Excellent Post. Can you please also provide the typical weighting for each activity to guide the planners ?
    Example: for Pump / Compressor / Blower
    Chipping & Padding - 5%
    Lifting & Rigging - 20%
    Levelling and Grouting - 5%
    First Alignment - 25%
    Final Alignment - 35%
    Final Check & QC Documentation Sign off - 10%
