“…While construction companies differ in size, knowledge and risk attitude (Lew et al , 2018; Teräväinen et al , 2018), two of the most important actors in the industry are architects and contractors (Hemstrom et al , 2017; Sariola, 2018). Architecture companies are professional service companies that are generally knowledge intensive, relatively small in size and often led by the principal architects (Hong et al , 2019; Oluwatayo et al , 2016; Salvatierra et al , 2019). Conversely, large companies usually dominate the contractor market, with others being mainly small and medium sized, labour intensive and typically family-owned (Teräväinen and Junnonen, 2019; Hong et al , 2019).…”
