Parsons Corporation�s story is one of a company that has quietly transformed our global standard of living by designing, engineering, and constructing energy, water, military, transportation, and commercial infrastructure. Its worldwide contributions are depicted through the personal recollections of staff memebers who were directly involved in creating Parsons� first-of-a-kind, one-of-a-kind project legacy. They offer insight into Parsons� accomplishments, starting with founder Ralph M. Parsons� engineering acumen in the oil industry in the 1940s through the firm�s present reconstruction efforts in European, Middle Eastern, and African countries. In many ways, the evolution of Parsons can be defined as a corporation�s technical response to an ever-evolving economic and political environment. However, it is also a story of how leadership and market adaptation turned a start-up consulting business with eight employees into a formidable global organization, employing thousands of professionals. From Parsons� mailroom to the boardroom, the author was given unlimited access to interview former and current employees and access little-known corporate archives and personal mementos of the staff to formulate this story. The book spans over 60 years of increasingly complex projects and is a testament to the often unsung engineering, technical, and construction professionals who, every day, deliver and service the world�s most reliable, safe, efficient, and visually striking infrastructure.
