Over the years, it has become clear that infrastructural development, more so the construction and rehabilitation of roads, is expensive. There have been numerous cases of stalled construction projects due to cash crunches in Kenya. According to the National Assembly Budget Committee, 3 infrastructural projects worth up to 9 trillion Kenyan shillings have stalled due to contractors' delayed payment and inability to complete the projects, mainly due to underquoting (Seboru, 2021).

Housing is a basic human need. Shelter for all was even listed among the millennium developmental goals therefore its significance cannot even be quantified.
