Schematic Design of World’s Tallest Building Completed
Commissioned by the South Korean-based Lotte Corp., the schematic design of a 107-story office tower and mixed-use/retail facility planned for construction in the city of Pusan, South Korea, has been completed by Parker Durrant International, Minneapolis. The 5.7 million-square-foot Lotte World II Tower is slated to be the world’s tallest building at 1,620 feet high.
The sleek steel-and-glass office tower’s adjoining facilities will include a hotel/
conference center, a multiplex cinema, an IMAX theater, a department store, and specialty retail stores and restaurants. It is expected to become a regional attraction and international tourist destination.
Initial work on the construction site has already begun, with completion of the retail/entertainment portion planned for 2006, and completion of the tower expected in 2008.
It’s not exactly a new concept; however, ergonomics is still misunderstood today. Buildings asked Edward Metzger, vice president, sales and marketing, BioFit Engineered Products, Waterville, OH, to share his thoughts on the topic.
Q: What are the most common ergonomic injuries?
A: Musculoskeletal disorders (MSDs) include injuries and disorders involving muscles, nerves, tendons, ligaments, joints, cartilage, and spinal discs. Carpal tunnel syndrome, a hand and wrist disorder resulting from a compressed nerve, is one of the most common examples of MSDs.
Ergonomic injuries occur far more often than you may realize. The Bureau of Labor Statistics reported more than 582,000 MSD cases in one recent year. MSDs account for approximately one-third of all occupational illnesses and injuries.
Q: While ergonomics is not a new concept, how well is it understood?
A: The understanding and appreciation of ergonomics in the workplace have increased greatly during the past 15 to 20 years. Seated office work is a good example. We used to think that no one could become injured sitting in an office. We now know that sitting is not restful, as it may appear, because individuals use nearly 100 muscles to balance in a seated position.
Workers who spend the majority of their day on seating that is too high, too low, too hard, or too difficult to adjust are placing unnecessary strain on back, leg, and stomach muscles. An awkward posture, repeated reaching, or other repeated motions can result in muscle strain, premature fatigue, reduced productivity, and a potential MSD.
Q: When purchasing ergonomic seating, should you expect to pay more?
A: If furniture is being selected solely on price, rather than the best quality/price combination, workers may end up with seating that does not provide a proper fit or meet basic ergonomic needs.
Easy-to-use ergonomic controls and easy, quick adjustability add to the usability and value of a chair, and also add to its price. For example, backrest tilt and seat tilt are functions that can make a chair more comfortable and versatile, but at additional cost. The bottom line, to use the cliché, is that “you get what you pay for.” Furniture that provides ergonomic quality and durability is cost-effective when you factor in its benefits.

Basic Design for Stability – Columns and Frames: AISC and the Structural Stability Research Council team up for a six-hour program focusing on the compressive strength of columns and frames to provide a fundamental understanding of buckling. With a strong emphasis on applications via example problems and case studies, you’ll understand the stability provisions in the AISC Specification, as well as methods of stability analysis outlined in the AISC Commentary. Authors: Theodore Galambos, PhD, University of Minnesota; Perry Green, PhD, University of Florida; Todd Helwig, PhD, University of Houston; Joseph Yura, PhD, University of Texas. Attendees will be issued 0.6 CEUs or 6.0 PDHs upon completion of the seminar.

Challenges Overcome at Georgia Cancer Center
Begun in October 2001, the Georgia Cancer Center for Excellence at Grady Health System faced numerous construction and design challenges, overcoming each with the goal of delivering a high-quality medical environment in Atlanta.
The Cancer Center occupies the ninth and tenth floors of Grady Memorial Hospital, totaling 64,000 square feet. It was necessary to keep one of Atlanta’s busiest hospitals operational during construction despite demolition and construction activity. Equally challenging, engineers were tasked with accommodating the weight of a PET/CT scanner in the middle of this existing high-rise building.
It was necessary for infrastructure on the newly dedicated floors to integrate with existing plumbing, mechanical, and HVAC systems ranging from 10 to 50 years in age. Completed in January 2003, the Georgia Cancer Center for Excellence adds in-patient/nursing care, clinical services, office/consult/waiting areas, imaging, wet lab research, and a pharmacy to the hospital. The project team included Boyken International Inc., HJ Russell Construction Co., Alcon Construction Co., HDR Architects, as well as owner representatives from the Georgia Board of Regents, and many other collaborators.
