Giants 300 Methodology
BD+C's annual Giants 300 list consists of U.S. firms that designed or constructed the largest volume of commercial, institutional, industrial, and multifamily residential buildings in 2007. Each spring, the editors survey the country's largest firms, ranking the top 300 across six categories: architects, architect/engineers, engineers, engineer/architects, contractors, and construction managers. Design firms are ranked on billings for work performed in-house. Contractors and construction managers are ranked on the value of construction put in place. For multi-year projects, only work from the survey year applies.
Please note: Civil engineering work (including roads and bridges), single-family homes, and certain building types (e.g., power plants, oil drilling rigs) are not included in BD+C's Giants 300 financial data.
