Crane · 2026
26007 - Avalon Dulles - Mobile - CRN2
Herndon, VA · near Washington Dulles Intl (2.5 mi)
What this outcome means
The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.
The proposal, in the filer's words
"This filing is for the mobile crane. This is corner 2 of the building. The mobile crane will be used to erect building on site. The mobile crane is a Grove RT 655L. The mobile crane will not reach heights above 155 feet AGL including most upper parts of the crane. The mobile crane temp. structure will be used on site from July 2026 to November 2028. The mobile crane will be mobilized Monday through Friday 7am to 7pm. The crane will be lowered when not in use and from sun down to sun up. The mobile crane will have red lights and flags."
