This chapter presents the sequence of events of a project from its design concept through the construction stage. It is intended to state and refresh the structural engineer's role and responsibilities in the design and construction process toward the common goal shared by the owner and the design professional: a quality project designed for its intended use and constructed within the budget and time restraints.
The structural engineer must bring into the forensic arena the academic training, practical knowledge, and experience (including successes and disappointments), and then use them in the role of a detective or investigative reporter.
