A Decision Model for the Investment in Technology to Reduce Concrete Rework

Developments in technology allow for improved processes in construction. Often, project teams face the option of acquiring new technologies, but it is not clear if the expenses merit the benefits. This paper presents a method to choose technology that can reduce rework in structural concrete caused by poor construction quality. The technologies considered are identified as those that can be used to improve quality monitoring during construction. The scope of the investigation was limited to structural elements, such as beams, columns, slabs and concrete walls. The research questions for this study were as follows: (i) what are the causes that lead to poor construction quality of structural concrete; (ii) how can technology be used to improve the construction quality and how effective would it be and (iii) can a decision model be developed to assist a contractor to invest in such technology. A decision model was developed, based on risk and cost, to assist the user in the investment decision of acquiring technology to reduce rework. The approach applies to mega project and smaller projects alike, all to the benefit if improved processes.
