Budget estimate

$500,000 – $2,000,000

The project covers two major sites (the Georgia World Congress Center and Centennial Olympic Park) and requires full hardware procurement, system integration, labor, testing, training, and a one‑year warranty. Based on comparable large‑scale irrigation upgrades for convention facilities, total contract values typically range from several hundred thousand to low‑multiple‑million dollars. Assuming equipment costs of $300‑$600 K, labor and program integration of $200‑$500 K, and additional support/warranty fees, a reasonable estimate is $0.5 M – $2.0 M. The final amount will depend on the number of controllers, site‑specific complexities, and any optional add‑ons.
