Golf Course Superintendent — Subgrade Preparation
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.
Subgrade Preparation
Subgrade preparation creates the surface that supports the next pavement or structural layer. The visible level and the condition of the material both matter.
Before moving material
Remove unsuitable material according to the project instructions and establish the formation reference.
Receiving operation and checks
Prepare for the specified compaction and acceptance process. Check levels, moisture and soft areas before the next layer is placed.
A geometric check cannot replace material testing.

Golf-course earthworks form designed contours and feature-specific surfaces. Smoothing away a deliberate mound or swale can defeat the course design.
Before moving material
Set out the intended feature and identify rootzone and drainage layers.
Receiving operation and checks
Complete the relevant drainage and turf preparation operations. Compare the finished shape with the feature design rather than a generic plane.
Greens, tees, fairways and paths need different acceptance criteria.

Uneven subgrade can create variable thickness in every layer above it. Correcting the surface is useful only if the underlying support is acceptable.
Before moving material
Identify soft areas and compare formation levels with design.
Receiving operation and checks
Complete compaction and specified acceptance checks. Check levels before base material conceals the subgrade.
A scraper does not replace proof testing or project-specific investigation.
