Abstract
The Architecture, Engineering, and Construction (AEC) sector is diverse. The industry’s market is run by businesses of different sizes, specialties, and subordinations, and each active company indirectly participates in adding value to the sector. This paper focuses on the functional distribution of local AEC firms in Southern Hungary, mainly in the South Transdanubia region. The work systematically gathers data about multidisciplinary AEC firms based in the region, introduces the main activities of the collected companies, and reveals the potential AEC divisions, by analyzing the popularity, net revenue, and number of employee factors for each professional division within the industry at the studied region.
