Globally, infrastructure development is critical in defining a country’s overall productivity and economic development Road infrastructure project performance is critical for every economy’s growth and development. It is vital to the economy in terms of wealth creation and job creation. However, road infrastructure projects in developing nations are more frequently underfunded, and a higher percentage of road projects built by local enterprises in these countries have encountered cost and time overruns, as well as failing to reach promised quality standards. The study investigated the influence of human management on the performance of construction projects by Kenya National Highways Authority in Nairobi City County. A descriptive research design was adopted targeting an accessible population of 10 ongoing road infrastructure projects within Nairobi City County undertaken by the Kenya National Highways Authority from 2019. The sample of the study comprised of 175 respondents made up of project managers, site engineers and project team members. A semi-structured questionnaire was used to collect primary data. Validity of the study instruments was assessed with the help of the supervisors. The reliability was determined using Cronbach’s alpha coefficient. If the coefficient is 0.7 or greater, it is considered satisfactory. Descriptive and inferential statistics were employed to analyze the data. Multiple regression analyses were used to determine the relationship between variables. The study results indicated that there was a positive relationship between human management and the performance of construction projects by Kenya National Highways Authority in Nairobi City County. The study concluded that human management improved the way road construction projects done by Kenya National Highways Authority (KeNHA) in Nairobi County performed. The study recommended that for successful delivery of road construction projects, given the role that human management plays, it is critical that qualified, experienced and competent human resource be engaged in road construction projects done by KeNHA. Keywords: Human management, Project performance.
