Abstract: Faced with the problems of ever increasing construction costs, more and more methods are being employed in an attempt to keep expenses to a minimum without sacrificing the quality of construction and the safety of the workers. One such method is the use of a steel trench box in lieu of sheeting and/or shoring. This can be a highly successful method if certain basic fundamentals are observed. The width of the trench box must be such that it allows the workmen to move about and lay the pipeline in accordance with the specifications. Therefore, the engineer and contractor must take into account the design of the trench prior to the use of the box.
