Description

The City of Houston’s Houston Airport System seeks qualified environmental consulting firms to provide on‑call aviation environmental services across its three major airports—George Bush Intercontinental (IAH), William P. Hobby (HOU), and Ellington (EFD). The work includes environmental assessments, compliance assurance, and related advisory services. The agency intends to award one or more contracts for an initial three‑year term with two optional one‑year renewals, targeting a 24% DBE participation goal. • Scope covers environmental impact studies, regulatory compliance reviews, and on‑site consulting for airport operations. • Contracts may be split among multiple firms, each providing on‑call support as needed. • Competitive bidding includes a pre‑submission conference (Oct 22, 2025) and a questions deadline (Oct 29, 2025).

Budget estimate

$2,000,000 – $5,000,000

Based on comparable multi‑airport environmental consulting contracts, a three‑year on‑call agreement for three major Houston airports would likely range between $2 million and $5 million total. The estimate considers the breadth of services (assessments, compliance, advisory), the need for specialized aviation environmental expertise, travel and on‑site support costs, and the inclusion of DBE participation goals that may affect pricing.
