Estimating Grade Fall
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
How to Establish Fall Across Land
Fall across land is established by relating target elevations to measured horizontal distances. Set the required direction before choosing a gradient or moving soil.
Before moving material
Identify start, end and intermediate controls.
Receiving operation and checks
Measure the constructed surface independently. Check intermediate points and receiving outlets.
The example calculations on this site illustrate geometry, not universal design slopes.

Grading before asphalt should establish the correct supporting profile and allow for the specified surfacing thickness. Resolve drainage and transition errors before paving.
Before moving material
Confirm the supporting-layer acceptance and finished elevations.
Receiving operation and checks
Hand over to the asphalt contractor with level and acceptance records. Check joints, gutters and connections to existing pavement.
Asphalt placement should not be presented as a function of the scraper.

Cutting, collecting, carrying, placing and grading are different tasks. A machine that drags material forward does not necessarily carry a contained load to a distant low area. Break the earthworks into these actions so the route, implement and checking method match the actual work.
Before moving material
Survey high areas, receiving areas and obstacles before loading.
Receiving operation and checks
Recheck levels before another layer or another operation covers the work. Track the destination of material as well as the appearance of the cut.
Material suitability, safe towing and compaction requirements remain separate decisions.
