Cost overruns have been a major source of concern to project clients and other project stakeholders for decades. The consequences of cost overruns include reduced guaranteed profits for the contractor and several additional issues for all stakeholders, including additional delays, contractual disputes, claims and litigation, inefficient allocation of scarce resources and project failure or abandonment. To address these problems, it is essential to establish effective cost control strategies to ensure projects are executed within budget. Several methods, techniques and tools have all been put forth to aid construction cost control. The increased usage of Information and Communications Technology (ICT) as well as digitalization and automation have fuelled the evolution of the fourth industrial revolution (Industry 4.0). The futuristic idea of Industry 4.0 is centred on digitization of a product’s value chain and the enhancement of productivity using a technologically diverse and industrialised automated manufacturing environment. However, there appears to be a paucity of scholarly research on the role Industry 4.0 technologies in supporting construction cost control. This research aims to appraise the existing methods, tools, and techniques for construction cost control with a view to identifying a more robust approach that meets the 21st century challenges especially in the era of Industry 4.0. This will be accomplished by conducting a comprehensive literature review which will classify the findings according to three main themes: methods, tools, and techniques of cost control. This will inform how to improve cost control of projects in the era of Industry 4.0.
