    Okay... here's the equation - pay no attention to the number 17, as it is simply the row in which I copied the formula. The $ sign fixes the number so when you copy the cell, it doesn't change the numbers in the formula, since excel likes to think too much.


    Hope this will clarify. Follow the example above:

    On the bid sheet:
    Column A = Description of item
    Column B = Quantity of item
    Column C = Unit of measure (EA, SQFT, BALE, etc)
    Column D = Price
    Column E = hidden column - don't worry about for moment

    Therefore, in the equation above, If C, the unit of measure, equals EA, SQFT, etc. then multiple B (quantity) times D (price). This formula rests in the materials column.


    Sitting in the equipment column, if C, the unit of measure equals DAY, EHR (equip hours), then multiple B (quanity) times D (price).

    Therefore, if I have in the following columns
    A: Rototiller B: 2 day C: DAY D: $30.00
    The column for equipment will pick up that this is an equipment calcualation, not material or labor, and therefore drop $60.00 into the equipment column.

    Hope this helps.

    PS - I separate the foreman and technician hours into two columns and designate them with F & T in the Unit of Measure (U/M) column. So I don't have to constantly type in the hourly rate, I have it fixed in an assumptions area with other mark up numbers (overhead, profit, etc). This way I reference the same number, and if I want to change the labor rate throughout the whole project, I only have to type it once, not each time labor was applied to the job.

    If you want more info or explanation on this, email me.
