Lean Construction Principles in Practice: Continuous Improvement in the Norwegian Construction Industry

This paper examines the role of continuous improvement in the Norwegian construction industry, focusing on the strategies, methods, and challenges faced by the country’s largest contractors. The study uses a qualitative survey methodology, including semi-structured interviews with key personnel. The findings show that all surveyed contractors engage in continuous improvement, with strategies stemming from self-developed business systems, training for skill development, and a culture of improvement. However, there are significant gaps between strategic intentions and practical implementation, influenced by cultural, organizational, and resource-related factors. The paper concludes that a more integrated and systematic approach to continuous improvement is needed to effectively address the industry’s enduring challenges.
