# EW volume comparison between DTM vs Grid Method and End Area Method

**Project file**can refer [here](https://largefilehosting.s3.ap-northeast-1.amazonaws.com/ProjectSharing/Update%20Blogpost%20Link/Earthwork%20Test.zip)

**Excel Spreadsheet** [here](https://docs.google.com/spreadsheets/d/1IpDiz1u3RVQ_1BMu7fJS-UteY-0q_bDYbe6OFCDHkjI/edit?usp=sharing)

From the spreadsheet, it is pretty clear that all three methods agree with each other quite well, as shown in the summary table below:

Note that

The volume needed before compact fill is equal to fill/shrink factor. The manual calc. and software calculation agrees with each other, as shown from the above screenshot.

Below is the sreenshot of the software outputs:

## **Scenario 1**

**Swell Factor** **= 1**

**Shrink Factor** **= 1**

1. DTM

2. Grid Method

3. End Area Method

## **Scenario 2**

**Swell Factor** **= 1**

**Shrink Factor** **= 0.8**

1. DTM
