**5. Analyses and discussion**

407 construction projects which constituted a category of the study population, was adopted for this study. Information on the project client were investigated. The distribution of projects sampled into the sub-variables of the project client characteristic was analyzed using percentage. The results are presented in **Table 1**.

On project client, **Table 1** shows that the projects sampled are distributed among Public (22.1%) and Private Individual (77.9%). These results show that the study covered short, average and long term projects.

#### **5.1 Levels of adoption of communication process based on project client**

The third research hypothesis was tested for difference in the levels of adoption of communication process between public and private clients. The hypothesis was tested using Independent Sample t-test and Mann Whitney U test at p-value ≤0.05. The results reveal that the differences in the levels of adoption of nine (9) communication practices between projects procured by public and private clients are significant. The results are presented in **Table 2**.

**Table 2** shows that the p-values for the test of difference in the levels of adoption of written (0.032), audio-visual (0.023) and electronic communication media (0.001), print (0.001) and electronic (0.001) communication channels and upward (0.021) downward (0.001) lateral (0.007) and horizontal (0.021) communication flows between projects procured by public and private sector client are less than the critical p-value (0.05), therefore, the test rejects the hypothesis. The results indicate that the differences in the adoption of written, audio-visual and electronic communication media, print and electronic communication channels and upward, downward, lateral and horizontal communication flows between public and private sector project are significant. The implication is that project clients have significant effect on the levels of adoption of the two communication media, two communication channels and four communication flows.
