What goes around, comes around
In the early years, I got some sound advice from Lloyd White—a salty and wise old guy at Lincoln Steel who had supplied steel to my father (who was a general contractor) for years. "There are a few ’bad actors’ out there who will do you wrong," he said. "Just remember, if you want to be in business for a long time, ’treat people right’ and they’ll be loyal to you. The bad ones will likely be at your mercy sometime in your career because what goes around comes around."

Structural engineers’ role in improving the sustainability of our nation’s infrastructure
Large parts of our nation’s transportation network are in need of repair, rehabilitation, restoration, or replacement, demanding massive amounts of resources. In the transportation design arena, structural engineers have a dominant voice in the selection of the form, type, and location of various elements of the infrastructure network, and thus, can exert greater influence in improving the sustainability aspects of these elements. Several aspects of design are discussed below.
Project and business management
As integral as computers and software are to our businesses, finding the ideal application for our unique situation may be easier than you think. Many developers offer a variety of software and web applications to enable your business to perform at its peak. Accounting, organization, timesheets, and document control are all examples of what is currently available specifically for engineering firms.
In response to an open invitation from Structural Engineer, a number of companies provided the following information about their products. Company web addresses are provided for immediate access to additional information.

Structural design performance
Ever since I entered this profession, structural engineers have been grappling with building codes and design standards. At that time, practicing engineers had many questions: Which codes apply to which jurisdictions? What has changed since the last edition of the code? How are the design standards developing and affecting the code? How does my structural design comply with the code? Though much has changed more than a decade later, the profession is still faced with many of these same questions.
The 2009 International Building Code An overview of the structural changes—Part 1
The International Code Council (ICC) uses an 18-month code development cycle and a three-year code publication cycle. This means a new code is published every three years with one supplement published between code editions. Thus, the successful code changes during the 2006/2007 cycle were published in the 2007 Supplement to the International Building Code (IBC). The successful code changes proposed during the 2007/2008 cycle are then combined with the changes in the 2007 Supplement to produce the new 2009 edition of the IBC.
Performance-based design A concrete shear core lateral system case study
The Bravern is a massive, 3 million-square-foot, mixed-use development that covers a 4.5-acre site. Located in Bellevue, Wash., a thriving Seattle suburb, The Bravern includes two class-A office towers and two exclusive condominium towers. These four high-rise buildings are situated over a three-story podium showcasing over 300,000 square feet of high-end retail space and 3,100 parking stalls located on seven levels of below-grade parking. DCI Engineers applied a performance-based design philosophy to analyze the seismic force resisting systems for this project in order to control the cost of the structure, while still ensuring a safe and practical design.
Structural performance on Waikiki Beach Meeting the challenges of luxury
Waikiki and Trump: the former is one of the world’s premier vacation destinations; the latter is synonymous with luxury development. The union of these two is the Trump International Hotel & Tower at Waikiki Beach Walk—a 38-story luxury hotel and condominium.
