The concept of project success remains unclearly defined due to different expectations from Different stakeholders. The well-known success criteria of time, cost and quality do not provide any practical information of achieving project objectives in an efficient way. Identification of the main factors contributing to project success will gain particular importance for stakeholders in the light of highly competitive environment of housing construction since housing construction projects represent one of the largest sectors in the construction industry in the country. Indeed the Kenya Vision 2030 strategy (2007) outlines the housing sector as having a crucial role to play in The achievement of the envisaged goals. The success of the industry is therefore important to a growing economy like Kenya. The main aim of this research project was therefore to identify rank and analyse the interrelationships between the most influential factors affecting the successful delivery of housing construction projects in the Ministry of Housing in Nairobi, Kenya. The study focused on five projects undertaken by the Civil Servants Housing Scheme in The ministry. Three different target populations segmented into four specialized groups that were involved in the construction project management process for the ministry in the past five years and the beneficiaries of the projects were the target. The groups were the project management team, the consultants' team comprising, the construction team and the project beneficiaries. A census of the entire target population for the project participants was earmarked for the study while simple random sampling was used to identify respondents from the beneficiaries of the projects. The sample design represented a total of 120 respondents. A questionnaire designed with both matrix and open ended questions was administered to the respondents and from the 120questionnaires sent out, 81 were received representing 67.5% response rate. Based on the Analysis of the data using SPSS computer software, success factors were ranked according to the impact on project success. Further, factor analysis was used to study the interrelationship between the factors. From the initial 72 variables, 29 factors were extracted and 16 factors were identified as critical determinants. The top 5 were: 'contractors experience', 'contractor's cashflow site management', 'employer's ability to honour contractor's certificates on time' and 'adequacy of funding from external sources'. Three of these are related to project funding, while The other two concerns the contractors' experience and effective site management. Funding is Therefore a critical factor for public projects, therefore implementing organisations must have clear funding structures for the projects to succeed. The research findings will contribute practically in the successful project implementation at the ministry and other public project oriented organisations, while theoretically the findings will be invaluable to other related policy makers and to the project management field of study. The current research may be developed further by increasing the sample size and studying the area more in depth by deploying different methodology. Increasing the sample size could help to identify more precisely the interrelation framework of success factors. This can provide a significant contribution to the existing literature by adding knowledge to the project management theory in a developing economy like Kenya. Finally as this study was focused on a specific type of project in one country, and a limited Location within one organisation, the research is not able to provide generalization regarding the construction industry as a whole. This may be the main limitation of this study since the conclusions cannot be applied to other organisations.
