Methodology and notes

Barbour ABI, provider of construction intelligence services and Building sister company, contacted more than 500 firms for this year’s Building Top Consultants’ Survey. They were sent a survey form asking for details on the number of chartered staff, non-chartered and technical staff, and domestic and worldwide fee incomes. Firms are ranked according to total UK chartered staff, and for QSs, architects, engineers and project manager by chartered staff in each respective discipline. Practices were also asked questions relating to: staff recruitment, wage patterns, margins, areas of work, and work expectations.

The survey relies upon firms completing and returning the annual survey form. For a variety of reasons firms sometimes decide not to take part. Only those firms that complete and return the survey form are included in the survey. Firms with any questions about the survey, or that wish to be included in the 2016 survey, should contact Barbour ABI
