AbstractEffective cost management is a vital requisite for successful Low-cost housing projects (LHPs) management and delivery. Whilst several attempts have been made to develop appropriate structured models for cost management practice, many of these models are fragmented and do not capture a holistic representation of the system components or their interrelationships in LHP settings. Moreover, these models are predominantly descriptive by nature – only identifying the components of cost management and not how they can be implemented within LHP settings. This research adopts an explicit sequential mixed research design to develop a bespoke LHP cost management model for process integration and evaluation in Nigeria. This identifies the structures and interrelationships needed to conceptualise and implement cost management practice effectively. Research findings highlight eight important techniques. These include target costing, approximate estimating, site meetings, Earned Value Analysis, on-site resource control, cash flow analysis, cost reporting and cost aggregation. However, it also needs to be acknowledged that it is important also to have: a well-developed client brief; detailed project designs and accompanying specifications; effective project planning and supervision; and competent teams (client and contractor) to discharge responsibilities. The importance of early contractor involvement was also seen as a core lever for success throughout the pre-design, design, and construction stages of LHP. The resulting model standardises cost management practice to provide a systematic ‘blueprint’ beneficial to project managers, cost managers and project management teams in evaluating and managing CMS processes more effectively in LHP settings. It is expected that the project department in Housing agencies adopts this model as a requirement for cost management practice in LHPs in Nigeria.
