Lifting with Cranes

On a hot summer day, who wouldn't want to jump into a cool and refreshing pool? And then, as the sun sets, what better way to relax than to slip into your own backyard spa -- summer or winter? But enjoying all that requires some regular attention. Remember, the water in your pool and spa is an ever-changing environment that calls for constant and careful monitoring. For some, this means hiring a professional service technician to come by once or twice a week. You can, however, take care of your pool and spa yourself. The need to treat water has been widely accepted for a long time. Sanitation, especially, is recognized as a means of controlling communicable diseases. The pool operator is expected to provide safe, clean water for bathers. More recently, however, the importance of mineral saturation, or 'water balance" as it is more popularly known, is recognized by those responsible for maintaining the pool and equipment. Water can become aggressive and destroy pools with corrosion, or it can become scaling and damage the pool with mineral deposits. The pool operator must learn about the use of chemical agents for sanitation and for control of pH, total alkalinity and calcium hardness. The operator is expected to protect both the swimmers and the pool itself. This chapter is written to present the necessary chemical treatments and sufficient background information to know when and how to use them.

Introduction: This book is not intended to teach you about the processes and terms and other mechanical activities of project management. This is a book about working with and leading people who are working on projects. My core premise is that great project outcomes are in large part dependent upon the leadership skills of the project managers. As an executive, I understand that great, passionate and capable leaders that also are well trained in the science of project management are the ones that drive great results. Alternatively, if I look hard at the many project failures that I've encountered in over two decades working for technology firms and now as an educator and consultant, project leadership is always an issue. If you are interested in growing your career as a project manager and perhaps leveraging your unique insights and skills in broader and higher management roles, it is critical for you to focus on building your skills as a leader.
