Fremont will be the first U.S. skyscraper to use all elevators for evacuation. In a U.S. first, a high-rise, when completed by the end of next year, will contain an elevator system that operates during fires to evacuate occupants.
Officials recently approved the construction of a $1.7-billion, 65,000-seat stadium in Carson City, Calif., a Los Angeles County city that could be the future home of the Chargers and the Raiders, two National Football League teams now based in San Deigo and Oakland, Calif., respectively.
Steven Tipping is developing and engineering what is likely the world's smallest seismically isolated structure. The 7,500-sq-ft building in Berkeley about a half-mile from California's Hayward fault is an investment property as well as an office expansion.
In September, the American Concrete Institute plans to publish a guide to help engineers meet the requirements of ACI's first model code for the repair of existing structural-concrete buildings.
A new standard for design guidance on legionellosis is currently available from ASHRAE, formerly known as the American Society of Heating, Refrigerating and Air-Conditioning Engineers. ANSI/ASHRAE Standard 188-2015, Legionellosis: Risk Management for Building Water Systems, sets minimum legionellosis-risk-management requirements for water systems.ASHRAE developed the standard in response to the 8,000 to 10,000 cases of Legionnaires’ disease reported each year in the U.S. More than 10% of those cases are fatal, says Tom Watson, chair of the ASHRAE committee that wrote the standard. Legionella can also cause a less-severe influenza-like illness known as Pontiac Fever.The standard is targeted for use by

The spaghetti-box shape performed poorly in wind-tunnel tests, especially regarding high wind loads and motion at the tower's top.The design solution was to remove windows and create five horizontal slots in the building at the double-height

Video Courtesy ThyssenKrupp Looking to expand versatility in building designs, Essen, Germany-based ThyssenKrupp Elevator AG has announced Multi, a cable-less elevator system propelled by magnetic induction. Multi will allow multiple elevator cabs in a single shaft and be able to travel horizontally as well as vertically within a building.According to ThyssenKrupp, the system will reduce the overall footprint of elevator shafts, increasing the usable space in high-rise buildings. "As the nature of building construction evolves, it is also necessary to adapt elevator systems to
