“…Dlungwana & Rwelamila (2003: 3) identified the key features of small-sized contracting firms as largely unregistered, operation in the informal sector of the economy, hardly any formal business systems, largest percentage of total contractors, and very few permanent staff, usually less than ten employees. Besides, the ownership structure is less complex (Hussain & Abdul Hadi, 2018: 21), and capabilities for innovation are relatively low (Martínez-Román, Tamayo & Gamero, 2017;Wang et al, 2018). The nature of contracts executed by small and medium-sized construction firms includes substantial maintenance works, refurbishment, and housing construction projects, which are carried out under lump-sum contract and through open tender procedure (Wasi et al, 2001).…”
