ABSTRACT
This chapter presents design errors and design deficiencies that have been discovered during construction, operation, and maintenance phases of various projects. It also presents procedures that can be implemented by the design and review teams to reduce or eliminate many types of design errors. Some blunders are senseless, and their occurrence is perhaps caused by an oversight or omission while details of the drawings are being worked out. Others may happen because a designer simply forgot to include some items in the design calculations, made a poor judgment or assumption, or perhaps overlooked the implications of the design criteria. Many other poor design provisions may not be errors in the real sense but may be least desirable from the point of view of plant construction or expansion or may not provide the desired flexibility and convenience in plant operation and routine maintenance.
