Crane · 2026
UCAR - Bldg. 1a
Boulder, CO · near Boulder Muni (0.8 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
"We will be using a fixed crane to remove the old skylight glass and replace it with new glass. We will swing crane away from runway line when removing and replacing glass as to not go any further North with the crane. We will only use the crane for a few days to remove and then a few days to replace the glass. The crane will be lowered when not in use."
