The Irvine Business Complex (IBC) is located in the City of Irvine (City) at the west most side of the City bordering with the cities of Newport Beach and Santa Ana. At the southwest border of IBC is the John Wayne Airport.
Map of IBC:
The IBC is one of the City's larger employment center. The other employment center that comes to mind is the Irvine Spectrum Area which will soon hold title to the tallest building in Orange County thanks to the 200 Spectrum Center office tower project. The IBC also has existing high rises, and according to a past OC Register article, one of which at one point was the fourth tallest building in Orange County. This is The Michelson office tower (19 stories, 286 1/2 feet tall), opened in 2007, which currently bears the title of Hyundai Capital towards the top of the building.

The City periodically updates their list of the status of residential projects (latest update: April 1, 2015) within the IBC along with a map illustrating those updates:
Accordingly, based off the City's updated list, Orange County Dense Developments provides a picture to those residential projects that are under construction or what looks to be like the site is breaking ground soon.
