Target population was 127 people while sample size was 96 respondents. Findings on frequently delay’s factors of commercial building projects of construction companies in Rwanda were presented in table 4.2 to 4.10 confirming delay’s factors of success of commercial building projects of construction companies; contractors related factors; technical equipment factors; owner related factors; environmental factors; design related factors; material related factors; project related factors; and interpersonal related factors affecting commercial building projects of construction companies in Rwanda. The results on the indicators of development of commercial building projects of construction companies in Rwanda were shown on table 4.11 to 4.16 said the indicators are cost performance; time performance; quality performance; clients’ satisfaction; health and safety; and functionality.

The findings revealed that there is a positive and low correlation between contractors related factors and cost performance with (r= 0.322, p<0.01); time performance with (r= 0.232, p<0.05); health and safety with (r= 0.250, p<0.05); functionality with (r= 0.320, p<0.01) for commercial building projects. The results revealed that there is a positive and strong correlation between technical equipment factors and cost performance with (r= 0.566, p<0.01); positive and low correlation between technical equipment and time performance with (r= 0.267, p<0.01); and health and safety with (r= 0.306, p<0.01); positive and strong correlation between technical equipment and functionality (r= 0.593, p<0.01) for commercial building projects. As conclusion, the objectives were realized, the research questions were responded; problem of the study was solved; research hypotheses were verified where all six null hypotheses were rejected by saying that there is different delaying factors affecting success of commercial building projects in Rwanda.
