🚀 This course “Project management in Revit”, will present how real-life Revit projects have used the Tool Dynamo - to calculate working hours and working costs.

To get the first data, we need a dynamo script and a Big Source Table.

What do we understand by “Big Source Table“?
This is a spreadsheet listing all Revit families and their properties that you use in your work.

For example, if you use five different types of foundations, you need to enter data on the cost and time for each type of foundation.
Typically, these tables are handled by the BIM department in your company which create Families for Revit.

In my own project I have used such a table with 6500 families and their properties.

Here we are particularly interested in the parameters - according to the volume of the elements is measured- volume in cubic meters, area in square meters or length in meters.

Equally important to us is the time and price quoted per unit of volume.
In my table all prices and times are fictitious.

We have assumed, for example, that 1m³ foundations is mounted in 20min. and the installation costs amount to 20 euros per m³.

We can also specify here in which order the elements are planned, or have to be manufactured or, as in our example, in which order the element are mounted.
For example, we know that the foundations are first assembled, so the number one.
And the truss installed at the end - therefore, the truss has the number 7.

Here you can also specify the product item for each element.

Other Elements or otherwise mentioned – Revit-Families that are not used in this project are also displayed here, which can be used in other projects, for example.
In order to fill in the table specifically for your project, you must include in this general table all Families that you want to use in your projects.
To begin with, you can only add five to six families from your project to understand how this works.

For each family you need to enter data about time and the cost for this element.
And also for the organization of temporary control - the order in which this element will be installed.
