Abstract

Although the architecture, engineering and construction (AEC) industry is highly relevant to national development, it suffers from significant productivity challenges. Beneath the design and documentation of structures, a dynamic, complex process is taking place, with constant modifications and feedback involving numerous professionals from different fields and their respective approaches and work developed using various computer programs. This diversity of factors converges within an iterative trial-and-error process and does not stop until a refined model is achieved. To understand traditional structural engineering companies (SECs) in Chile involved in building private procurement projects, 25 non-value-adding SEC activities were identified and classified according to typical lean management waste categories. These were initially validated by a panel of experts and then confirmed through a survey of 37 companies. The identified activities reduce the productivity of SEC organizations, contributing to low AEC industry indicators.
