Influence of Management Ability of Contractors on Performance of Road Construction Infrastructural Projects: Beyond Project Implementation

The study objective was to establish how management ability of contractors influences performance of road construction infrastructural projects in Nairobi County, Kenya. The target population for the study was 460 and a sample size of 210 drawn from the same. As per the tools used, 152 questionnaires and structured interview schedules were successfully completed, representing 72.8 % return rate. Simple linear regression model was used and a test for significance computed at 0.05 level of significance. Hypothesis was stated in null form for which the following results were recorded: that, R=0.157, R2=0.025, β=0.124, t=1.956, F (1, 151) =3.827, p=0.052greater than0.05, thus we failed to reject the null hypothesis for lack of sufficient evidence. It was therefore concluded that contractors’ management ability does not significantly influence performance of road construction infrastructural projects. This suggests that management ability of contractors explains well the success of the project from the time construction starts to completion phase but not performance.
