Inspect the ground before it disappears beneath the lawn.
SAWS inspection guidance addresses soil beneath new sod and connects establishment approvals with the irrigation review process. Confirm the requirements for your project before turf delivery so missing preparation does not surface only at handover.
Ask to review preparation and irrigation coverage while the ground is visible. For a new home, assign establishment responsibility before move-in. On commercial grounds, protect new turf from shortcuts and maintenance traffic, and divide large installations into manageable phases. A new-landscape watering allowance should be confirmed with the provider, not assumed in the construction schedule.
