BOQ

BOQs (Bill of Quantities) are very useful for quickly calculating quantities while retaining the details of your calculations so that you can update them more easily later on :

• 1 BOQ is a calculation of quantities (no notion of price)
  
• 1 BOQ consists of calculation lines
• Total BOQ = sum of the result of each BOQ line
  
• BOQs are variant-specific (or BIM Template-specific)
• All mathematical functions are recognized (see 📄 Math operationsfor more details)
• 1 BOQ can be called as a variable in 1 other BOQ via #boqname
• Possibility of using conditional forms

• BOQs are centralized. This means that:

  • you can modify them before you start writing a Variant
  • you can create them without linking them to a product range
  • you can use them as many times as you want
  • 
    

Example:

In this example :

• The area of a roof is calculated.
• The user named this BOQ: “sroof”
• The user named their first line “main roof” and entered the expression “12*8+4*4.8” Bimbal automatically calculated the result of this expression to be 115.20
• The user named their second line “garage” and entered the expression “4,2*6,3” Bimbal automatically calculated the result of this expression to be 26,46
• Bimbal calculated the total for this BOQ as follows: 141.66
• The user can now use the value of this BOQ as a variable wherever they want by calling it with the #sroof function
  
  

Example of advanced use

Suppose you want to charge for earthworks at a flat rate if the quantity is less than 150, or at a detailed rate if the quantity is greater than or equal to 150 :

• you create an “excavation” BOQ in which you calculate your earthwork quantities
• you create another boq “excavation150” with the expression 
• you create another boq “excavationdetails” with the expression #excavation>=150

If your earthwork quantity is 100, the BOQ “excavation150” will return the value “1,” which will count the product to which it is associated. The BOQ ‘excavationdetails’ will return a value of “0,” which will not count the product to which it is associated.
