# Defining parameters- one time

There are a few base lines that you are required to fill in beforehand, these parameters need to be added only once by a company admin and will be available for all projects throughout your work on the ConWize system.

**One-time configuration (relevant for all projects):**

**1. Base Variables-** You are required to add which variables you would like to asses within your project. For example: number of flats, metric units of the basement or car-park. This will be useful later when you enter the data specific for each project.

Go to: Settings 🡪 Analytic settings 🡪 Base variables 🡪

**2. Cost Element Types-** It is important to attribute each cost element to a certain group so that you can analyse the data later on. For example: opening a group named "cement" and adding all the cost elements that are associated with it.

After adding a group the system will automatically open three parameters for it.

**C**- Cost**Q**- Quantity**QwD**- Quantity without depreciation

Now these parameters will be available for your future use.

** **Please note that if you don't associate a cost element to a group the data for that cost element will not be calculated in the analysis.**

Go to: Settings 🡪 Estimate 🡪 Cost Element Type 🡪 Group 🡪

**3. Analytic Parameters-** After adding the two sections above you are now ready to configure the actual formulas you wish the system to calculate.

Go to: Settings 🡪 Analytic settings 🡪 Analytic Parameters 🡪

Here you are required to type in the formula according to the groups and base variables you added priorly. For example: cost of electricity divided by number of flats. You can use all math equations (plus, minus, multiply, divide).

Note that for your convenience you are able to add a parameter that sums your total cost of the whole project, or total cost of the elements that are categorized in a group.

For the system to calculate the data and show it in a range, you can add your minimum and maximum.
