Seeking to revitalize the site of the once thriving Wilshire Grand Hotel in downtown Los Angeles, development of the Wilshire Grand Center forever changed the skyline and became a vital part of the ongoing downtown renaissance. As the first skyscraper in Los Angeles built without a flat roof, the seventy-three-story mixed-use office and hotel tower stood as the tallest building west of Chicago at the time of its completion. As a destination for business travelers and tourists, the four-star InterContinental hotel sets the standard for luxury accommodations. Guests check-in on the 73rd floor sky lobby - a first in Los Angeles where they have breathtaking 360-degree views of the city. The commercial spaces include retail, restaurants and Class A office space.
The Wilshire Grand Center is the first building in downtown Los Angeles that is a composite structure with a concrete core and structural steel and glass exterior. The concrete core gives the tower stability against seismic events and serves as a protection in the event of a fire. The building's frame features three levels of buckle-resistant bracing that act as shock absorbers against earthquakes. The strength of the core allows for smaller exterior columns and provides the visitors with uninterrupted views in every hotel room.
Prior to starting construction on the building's vertical core, pouring the foundations was critical to the structural stability of the project. The building's foundation was placed during a record-setting concrete pour. Coined "The Grand Pour," foundations for the tower were poured during an 18.5-hour period, setting a new Guinness World Record for the longest continuous foundation concrete pour at 21,200 cubic yards.
