AGC and Computer Guidance Corporation conducted the survey that serves as the basis for the 2013 Construction Hiring and Business Forecast during the final two weeks of November and first three weeks of December 2012. Over 1,300 firms from . and every state except for Delaware — primarily from among the 20,000 general contractor or specialty subcontractor members of the Associated General Contractors of America — completed the survey. Contractors who completed the survey were entered into a raffle to win a $100 Amazon gift certificate. Other than that, firms and their employees.
