Level 10 Construction Announces Latest Benchmark For 181 Fremont–New Standards For Earthquake Safety
Level 10 Construction completes 40 floors of the structural steel build-out for 181 Fremont Street in San Francisco, and announces new standards for earthquake resilience.
Steve DeWees, project executive for the 181 Fremont Street project, said the tower's resilient support, designed by structural engineer Arup, allows the building to flex in a seismic event.
"This design would virtually eliminate structural damage from a significant earthquake" said DeWees, "and would allow the building to be occupied the next day. It will be the most earthquake resistant building on the West Coast. "
Structural steel is being installed with the assistance of a Wolffkran 700 B Luffing tower crane, the first of its kind being used in the U.S. The 700 B Luffing tower crane is known for its ability to move extremely heavy loads at quick line speeds within a tight urban footprint.
"The Luffing tower crane is one of the only cranes made today that has the capacity needed for the size of steel that is being used in the construction of this building," said DeWees.
"We have had some very heavy picks that had the crane at its max capacity, around 105,000 pounds," DeWees added. "We have heavy steel box columns on six corners of the building, and each segment is five inches thick. There are welded to a box and erected one to two floors at a time. Most cranes in the U.S. don't have the capacity to pick that weight out at the furthest points."
181 Fremont, an 802-foot-tall, 70-story luxury residential and office tower in the SOMA neighborhood of San Francisco, is set to transform the San Francisco skyline. Designed by Heller Manus Architects and developed by Jay Paul Company, the $540 million tower features a state-of-the-
The building includes 432,000 square feet of Class A office space, as well as 67 luxury condos on the top 17 floors. It is pre-certified LEED platinum. The lobby is being designed by FORM4 Architecture;
181 Fremont incorporates innovative design strategies for sustainability, water savings, and energy efficiency. As part of the building's pre-certified LEED platinum status, Level 10 Construction has installed a grey water system on Level B5, the lowest floor in the building. The system will recycle 1.5 million gallons of water per year for toilet flushing throughout the building. A large parking garage on basement Levels B3-B5 of the building houses 125 vehicles. The parking garage operates with the assistance of an auto-lift at a valet drop off. The building also features emergency evacuation elevators, the first of their kind in the country.
Sixty-seven ultra-luxury condos, known as 181 Fremont Residences, occupy the top 17 floors of the tower and have a magnificent view of San Francisco from every room. Forbes says the condos are "the most luxurious residential high-rise on the West Coast." The interiors of the residences are designed by Orlando Diaz-Azcuy Design Associates (ODADA) and feature high-end finishes sourced from throughout the world. A presentation center for the condos and a condo model is located at 101 California, 42nd floor.
