Increased use of computers has led to sophisticated techniques of structural analysis and has increased manufacturing and fabrication capabilities. This added degree of sophistication has resulted in more complex structures being designed and built with structural members that have long spans, shallow depths, and contain a high percentage of reinforcing steel.

In the past, during the course of developing placing drawings, the detailer often suggested solutions in areas where the details were incomplete and where the reinforcing steel appeared to have constructibility problems. Usually these solutions were used only after their acceptance by the architect/ engineer (A/E). Unfortunately, many problems do not surface during the detailing phase but rather occur during construction. The A/E and the contractor, working together, then solve the problem.

The A/E prepares the structural design to meet the requirements of the applicable building code and provides sufficient definition through the contract documents to convey all the requirements for detailing reinforcing steel. It is then the detailer's responsibility to develop all of the dimensions and quantities of the reinforcing steel to conform with the structural drawings and project specifications of the A/E.

As the complexity of design and construction increases, it is imperative that both the A/E and detailer understand their responsibilities clearly. The responsibilities of the A/E and the detailer, as they apply to the reinforced-concrete industry, are stated more clearly by the following separate sections.

This standard presents values in inch-pound and SI units. Hard metric values are usually not exact equivalents; therefore, each system is to be used independently of the other. Combining inch-pound and hard metric values can result in nonconformance with the standard. Soft metric values are exact equivalents, so combining inch-pound and soft metric values conforms to the standard.
