Evaluating Irrigation Bids for a 40-Building Complex

How to Compare Contractor Proposals Fairly

Joanne's subdivision committee needs to evaluate bids from multiple companies using different products (Toro, Weathermatic, Rain Bird, Hunter). The key is apples-to-apples comparison.

Best First Step: Hire an Independent Consultant

Engage an Irrigation Association Certified Designer with contractor experience. They work for you, not a manufacturer. They'll:

• Develop a master design and specification.
• Ensure all bids quote the same materials and methods.
• Provide construction oversight.

Do Your Own Research

Visit these resources:

• Irrigation Association – find certified designers
• American Society of Irrigation Consultants
• Manufacturer sites: Rain Bird, Hunter, Toro, Weathermatic

What a Consultant Provides

• Non-proprietary specifications based on site needs.
• Professional plans like an architect's drawings.
• Construction supervision to ensure design intent.

Red Flags in Bids

• Vastly different zone/head counts between bidders.
• No as-built drawings promised.
• No insurance certificate or references.
• Unrealistically low price ("too good to be true").

Trust Your Instincts

This is a long-term relationship. Choose a contractor you're comfortable with—communication matters as much as pipe size.
