IRRIGATION / SPRINKLER ESTIMATING.

## Bidding irrigation work in Phoenix is not the same as bidding it anywhere else Phoenix sits in the Sonoran Desert. Average annual rainfall is under 8 inches. That means every residential and commercial property you work on depends on an engineered irrigation system to keep anything alive — and every homeowner, HOA, and property manager knows it. Demand is constant. So is competition. When you walk a job here, you are not just counting heads and calculating pipe runs. You are sizing for extreme heat, accounting for ET (evapotranspiration) rates that peak above 0.35 inches per day in July, specifying pressure regulators for municipal supply lines that regularly run above 80 PSI, and often designing separate drip zones for desert-adapted plantings versus any turf that remains after city water conservation mandates. Estimate.Pro is built for that level of specificity. It handles the full scope-of-work — zone counts, controller specs, backflow preventer requirements, valve manifold layout, head spacing by precipitation rate, and drip emitter tallies — and prices it against your own saved material cost workspace. You set your supplier pricing. The calculator does not assume Home Depot retail. ## What the 8-minute bid target means on a Phoenix irrigation job The median time from starting a walkthrough to sending a client-ready bid on Estimate.Pro is 8 minutes. That number reflects a real workflow: 1. You walk the property. On supported devices, AR measurement captures linear footage of pipe runs and zone boundaries directly. On any device, photo measurements are flagged as estimates so you are never presenting false precision. 2. AI generates a scope-of-work draft. Zone count, controller type, backflow assembly, wire runs, valve boxes, sleeves under hardscape. 3. You review and adjust. Add a drip manifold for the xeriscape bed. Swap the rotor heads for the turf strip. Change the controller to a Wi-Fi unit because the client asked. 4. You send it. Eight minutes is achievable because the system knows irrigation. It is not a blank spreadsheet with a timer. ## Phoenix-specific scope items that slow down hand-built estimates **Backflow preventer permits.** The City of Phoenix Water Services Department requires a permit and inspection for any new or replacement backflow prevention assembly on a potable water connection. That permit fee is a line item. Estimate.Pro lets you build it into your template so it never gets forgotten. **Water conservation compliance.** Maricopa County and Phoenix city ordinances reference the Arizona Department of Water Resources guidelines. Some commercial bids require a water budget calculation tied to the Arizona ET-based landscape water-use standard. Knowing your precipitation rate per zone and your plant-factor assumptions matters when a landscape architect or HOA manager reviews your bid. **Caliche.** Subsurface caliche layers are common across the Phoenix metro. Trenching through caliche requires a rock saw or pneumatic hammer, and that labor cost is meaningfully higher than standard soil excavation. Your estimate needs a line item for it when site conditions indicate it. **Sleeve requirements.** Driveways, sidewalks, and hardscape crossings require Schedule 40 PVC sleeves. In new-construction subdivisions across Maricopa County, sleeve location and sizing often appear in civil drawings. On retrofit jobs, you are estimating them from a walkthrough. Either way, they need to be in the bid. ## Pricing for Phoenix irrigation contractors Estimate.Pro offers a free tier with no credit card required — useful if you want to run a real bid before committing. Pro runs $39 per seat per month. Elite runs $79 per seat per month and adds Stripe Connect invoicing with 0% platform fee, plus invoice exports. Crew is $399 per month flat for larger operations running multiple crews across the Valley. On the Free tier, Stripe Connect carries a 3% platform fee. On Pro and above, that fee drops to 0%. There is no per-bid charge. Run 3 bids a month or 300. ## Built for the 25 trades that make up a full-service landscape and irrigation operation Many Phoenix irrigation contractors also handle landscape installation, synthetic turf, concrete flatwork, or low-voltage lighting. Estimate.Pro covers 25 trades. You can build a combined irrigation and landscape estimate in one document without switching tools or merging spreadsheets. If you subcontract electrical for pump systems or controllers, you can track that scope separately within the same job file. ## Start with a real Phoenix job Create a free account, import your material costs from your current supplier pricing, and run your next residential or commercial irrigation bid. The free tier is permanent — not a trial. If the 8-minute target holds up on your first real job, Pro pays for itself on the second bid of the month.
