Build the landscape irrigation zone takeoff review record
Use irrigation plans, planting plans, civil utilities, details, schedules, and available water-source information. Record each zone, valve, served area, equipment type, and design note.
Do not create performance assumptions that the documents leave to delegated design. Use the site work estimating as a related control, but keep this takeoff tied to its own drawing population and cost lines.
Check quantities and scope conditions
Measure mainline and lateral pipe by size and route basis. Count valves, boxes, heads, emitters, controllers, sensors, sleeves, backflow equipment, and connection assemblies shown. Separate trenching through soil, paving, and planted areas because restoration differs.
AACE recommended practices provide general estimating references. The project documents and approved estimate basis control the actual quantity and scope decisions.
| Review field | Required record |
|---|---|
| Population | Location, type, and source |
| Quantity | Measured basis and unit |
| Interface | Included work and package owner |
| Disposition | Estimate treatment and reviewer |
Reconcile the estimate before release
Reconcile zones with planting and hardscape areas, then trace control wire, power, water connections, testing, startup, and seasonal requirements. Keep permits and design responsibility explicit when they are not settled in the bid documents. Close open assignments through the construction scope matrix guide and preserve the decision with the estimate revision.
