Turf Underlay — Compaction Handover
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.
Turf Underlay Preparation
Turf underlay needs a consistent growing layer over a correctly formed base. A smooth top surface can conceal an uneven distribution of suitable soil.
Before moving material
Check the formation and the growing-medium requirements.
Receiving operation and checks
Complete the venue's final soil preparation and turf installation. Check local low areas and underlay thickness.
Do not infer a turf rootzone specification from the word underlay.

A sports-turf handover should identify the formation, drainage and growing-layer system delivered. Playing-surface appearance alone does not establish venue acceptance.
Before moving material
Obtain the applicable project and sport requirements.
Receiving operation and checks
Complete the venue's inspection and release process. Retain measured levels and relevant construction records.
No sport or venue compliance is claimed from illustration or grading alone.
Read the complete Sports Turf Surface Handover guideThe Surface Is the Handover
The surface is the handover between operations. An excavator may finish its excavation, but the roller still needs suitable material, lift thickness and moisture. A scraper may finish shaping, but the irrigation operator still needs a connected fall to a usable outlet. Define acceptance at each transition instead of allowing the next machine to inherit an unresolved problem.
Before moving material
Name the operation that receives the surface and agree its requirements.
Receiving operation and checks
Release the area to the next operation only after outstanding defects are identified. Use independent level checks and project-specific material tests where required.
Visual smoothness alone does not prove compaction, bearing capacity or hydraulic performance.
