The quality of bridges in Uganda was reportedly poor as several national bridges have collapsed or been washed away by rain soon after construction. Several studies have been carried out on total quality management practices and product quality in bridge construction, however few studies are known about the relationship between total quality management and product quality in Uganda bridges.

This study aimed at examining the relationship between total quality management and product quality in bridges in Uganda. The study used a cross sectional survey research design with a study population of 143 staff members from which, a targeted sample of 125 respondents was randomly selected. The actual respondents were 103.The study used semi- structured self-administered questionnaires and 12 indepth key informant interviews. The study results on all the three aspects revealed associative positive significant relationships between supervision and product quality (r=0.294*; p=0.003; Adjusted R-square= 0.077); process improvement and product quality (r=0.408**; p=0.000; Adjusted R-square=0.158); prevention of defects and product quality (r=0.659***; P= 0.000; Adjusted R- Square=0.429).

The respondents mainly agreed on the statement of all the three aspects; there is supervision, process improvement and prevention of defects (Mean= 4.10; SD= 0.825; Mean= 3.955; SD= 0.986 and Mean =3.101; SD= 1.394 respectively). In conclusion, all the three aspects significantly affect product quality. There is need to focus on training of all levels of staff especially technicians in industrial best practices and technological improvement, ensuring use of the exact materials specified in the bill of quantities.
