Just a short explanation about what the excel sheet is for.

When building a road the most important test done is a test for compaction. A road is essentially built by adding layers of material on top of each other of increasingly good quality and higher compaction. Once we build a section (of a layer) we run a number of physical tests and the Data sheets verify if the compaction is acceptable. The summary sheet then shows the layers based on the location (chainage/distance from the beginning of the road).

Traditionally the summary would have to be done manually which is an absolute nightmare.
