Engineering News

ENR attempts to bring structure to an otherwise huge and chaotic construction industry by performing annual surveys of its key segments, and ranking companies engaged in general contracting, specialty contracting, engineering, architecture and environmental services, among other specialties. The rankings, based on annual revenue at home and abroad, are further divided into specific market categories. ENR Sourcebooks take that market analysis to a more detailed level by ranking industry leaders in particular market subsets. Analyses marked with a PDF icon require an annual ENR paid subscription membership to access. If you are not a paid member, sign up here.
