In my portfolio I have attempted, through projects and post module work in both a large and a small start up company, to examine consulting engineering firms as businesses. Firstly identifying the key issues then developing a framework of ideas that could be used by others. Because of the lack of literature directly related to the practice of consultipg engineering in construction I have looked outside that industry for references to guide me. In this summary I have attempted to consolidate the information gained. This would be useful as a starting point when assessing an existing businesses or as guidance for start-up firms.
