An investigation of corporate approaches to sustainability in the US engineering and construction industry

Sustainability involves focusing on a project's impact in three areas: (1) environmental; (2) economical; and (3) societal. In reality, companies' approaches in the three areas are not evenly distributed. A study of current trends in the US construction industry related to the emerging focus on sustainable construction will be of great value for the engineering and construction industry to recognize the differences in corporate approaches to sustainability, for the sake of team alignment. A random cross-section of 300 companies, consisting of 150 owner companies, 75 contractor companies and 75 design firms representing a variety of industries, was selected from annual company data assembled by the weekly construction news publication Engineering News Record (ENR). To identify sustainability-related concepts within the context of these company documents, content analyses and chi-square statistical analyses were performed on the selected companies' publicly available annual reports and mission/vision/values statements. The primary objectives are to: (1) identify concepts of sustainability that are currently being emphasized within the US engineering and construction industry, possibly at the expense of other concepts; and (2) develop an understanding of the relationships between various company and industry groups related to the fundamental concepts of sustainable construction.
