The Kingdom of Saudi Arabia (KSA) construction sector is an important industry and contributes approximately 20% of the gross domestic product (GDP). However, uncertainty, complexity, sustainability and Saudi Arabia National Policy Plan 2030 are among the most important features of the current construction business environment in the KSA. Therefore, for the KSA construction organisations, the creation of economic value by addressing the above issues now increasingly poses real profound strategic challenges. This paper focuses on key knowledge management (KM) strategies that the KSA construction organisations implemented en route to organisational competitiveness. The findings are in the main, based on semi-structured interviews with 46 professionals from 30 construction organisations. The data analysis revealed that, the key initiatives implemented broadly under the umbrella of KM are knowledge sharing initiatives, knowledge capturing initiatives and knowledge mapping initiatives. The scarcity of knowledge and expertise is, and will continue to be, a huge challenge for many construction organisations in the KSA.
