How to Model Common Improvement Strategies on eTool
Now that you have completed the Reference/Business as usual design it’s time to model your improvement strategies. With our new ‘Scenarios’ feature, building your proposed design by adding single improvement strategies is now much easier to do in eTool. In case you haven’t already, we demonstrate how the new ‘Scenarios’ feature works in our Intermediate Training course. So please ensure that you’ve completed both your Beginner and Intermediate training courses.

- Make sure same MPa is specified
- Make Sure same reinforcement % is specified
- Use ‘Bulk Swap’ feature to change the concrete (materials) to correlating fly ash quantities.

Replace Carpet/Tile for Timber Floor
- Know m2 of carpet/tile to be replaced
- Add timber floor at correct quantity
- Bulk swap disposal method, 50% recycle, 50% compost is an ok assumption
- Delete/reduce the corresponding amount of carpet/tile
