Salesforce CEO Marc Benioff on Thursday presided over an official "topping off" ceremony for the Salesforce Tower, now San Francisco's tallest building at 1,070 feet.

At the ceremony, Benioff quipped, "My grandfather used to tell me that the future of San Francisco is rising up."

"Building tall buildings is fundamentally an aspirational act, and an act of optimism," said the senior principal of Pelli Clarke Pelli during the ceremony. The architectural firm designed Salesforce Tower as well as the under-construction Transbay Terminal seen here below.

Benioff said the top floor, the 61st, will become a community gathering space called the Ohana Floor after the Hawaiian word for family. The space, with sweeping views of the city, will be a Salesforce conference and event space during business hours. At night and during the weekends, the space will be available to a wider community of partners and nonprofits for use free of charge.

Looking out over the San Francisco Bay, the taller of the buildings in the distance is the residential One Rincon Hill South Tower, which was completed in 2008 and stands 60 stories and 641 feet tall.
