Bill of Quantities – (Fixed Cost) part 5

When we start with calculation for project, for each Bill of Quantities, we could have specific fix costs. I described full calculation process for each Construction Position, but all of them where variable costs. That means, when we have to complete some position work, we need to consume some items (goods or materials) or some labor (mechanization, vehicle or person). As we have more Construction Positions work, we would have more item and resource consumptions (or subcontract work, as well). All of them are variable costs.

On the other hand, we could have some specific costs who are not linked to Construction Position execution, bit there are linked to complete project. These are e.g.: some project taxes, project preparation, project insurance, staff accommodation… All of them are fixed costs and we cannot link them to one of the positions.

For each BoQ, we can add them to project by insert in linked table ‘Fixed Project Costs’ and fill their cost. When we fill of them, on BoQ Header, we can see Total BoQ Fixed Cost.

We can insert fixed costs by starting command (three points) near field and after that we need to insert cost values by specification. When we finish cost inserting, we need to assign this cost to positions. We can assign total fixed cost to all positions or only for selected. If we want assign cost only for selected, we need to mark/unmark fields ‘Cost Using’ for each line. After that, we need to start command ‘Apply Fixed Cost’ and NAV will place parts of fixed cost to each selected position. System use proportional method of placing costs. When this is finished, field ‘Assigned Fixed Cost’ on header will be marked as sign that fixed cost is placed to lines.
