Building Burning Near Pacific Place?

We're working in a building next to Westlake Center, and just heard about a bajillion emergency vehicles go by. Looking out the window, they're all Fire Dept cars and trucks, and smoke seems to be coming from a construction site next to Pacific Place. Not that horrific billowing clouds of black kind of smoke, but disturbing nonetheless. There must be at least 12 emergency vehicles blocking the street. Anyone in the area know what is going on? (Word to the wise: don't take Lenora Olive home if you work downtown...)

UPDATE (3:59 PM): SFD's real-time response list shows 15 units responding to a "fire in building" at 8th Ave. and Olive Way.
