Abstract

In this study a computerised management system was developed to aid major contractors in improving cost control performance in construction projects. The system was developed by synthesising all construction cost-related functions into a comprehensive framework, taking into account both cost overrun factors and mitigating measures. These factors and measures were based on the findings of previous studies by the authors, in which 10 cost factors were specified as the most potentially controllable by contractors of an observed 59 influential factors identified in construction projects in Iraq. The system was then developed using Python programming language to incorporate the material, labour, and equipment costs of each construction activity. The system was then compared to in real life implementations in seven types of construction projects undertaken by the State Company for Project Execution of the Ministry of Transport, a major contracting company in Iraq, with the results showing that the system can be successfully utilised by major contractors for cost control during construction.
