Respondents have been involved in various types of building projects (commercial, residential, and institutional).  Most do at least two of these three types of work.

Respondents have worked on renovation and new projects, with slightly more renovation work reported. More than one-quarter of respondents (28%) regularly work on both types of projects.

Respondents have worked on public and private building projects, with slightly more private work reported. Twenty-eight percent (28%) of respondents regularly do both types of work.

This background information indicates that respondents have diverse types of project experience; their overall work experience is fairly typical of the general population of building professionals. I also know that people from both large and small firms are represented in this survey.
