The Salesforce Tower -- San Francisco’s tallest building and the second-tallest west of Chicago (behind the steel-framed Wilshire Grand in Los Angeles) -- topped out last week. The final steel beam was placed on the 61-story, mixed-use office and retail tower, soaring to a height of 1,070 ft in the South of Market district downtown.

The project uses 10,000 tons of structural steel, fabricated by The Herrick Corporation (an AISC member and certified fabricator and erector). Magnusson Klemencic Associates engineered the building with enhanced seismic safety and high-performance design features in mind. The project features a uniform steel and glass curtain wall system that wraps the tower’s structural steel framing, which surrounds a concrete core. Forty-two 5-ft-by-10-ft steel-reinforced concrete foundation elements extend to bedrock. The 14-ft, 9-in. slab-to-slab distance accommodates approximately 13-ft unfinished ceilings, 10-ft drop ceilings and 10 ft-high continuous clear glass windows. The column-free interior provides maximum natural light to the work space. The top 150 ft of the tower will feature the highest public art light installation in the U.S.

The completion of the project is scheduled for July. For more information, visit www.salesforcetower.com.
