Impact of knowledge management on construction projects

The implementation of knowledge management strategies on construction projects can accrue benefits such as improved performance and continuous improvement. However, many projects are still not utilising knowledge management fully and are thus plagued with inefficiencies, repetition of mistakes and lack of lessons learnt. Poor skills, design changes, errors and omissions contribute to the internal failure cost element of the overall cost of poor quality on construction projects. This study aimed to investigate the extent of the impact that knowledge management has in reducing the cost of poor quality and used a mixed-methods approach. In-depth interviews were conducted with 25 construction industry experts on knowledge management across the UK, followed up by a questionnaire survey of 114 respondents. The data obtained were analysed using thematic analysis and descriptive statistics. It was found that knowledge management had a positive impact in reducing the cost of poor quality, in particular in the area of knowledge transfer through apprenticeships and mentoring. This implies the importance of managing the tacit knowledge of employees through 'socialisation' initiatives. This study contributes to the existing body of knowledge by providing a knowledge management framework for reducing the cost of poor quality on construction projects.
