Rework is systemic and a recurring decimal and It is triggered by several factors, which emergence create scenarios, which degrades project cost, quality and schedule performance, and overall project performance. This study therefore examined the perception of construction professionals on the factors that triggers the emergence of rework in the Nigerian construction industry. This was achieved by determining the predominant rework triggers that affect project performance, identifying rework triggers in which the professionals view varies significantly, and examining the category of rework risks triggers that contribute more to rework incidences. The study adopted a quantitative survey approach in which structured questionnaire was adopted as the research instrument. Mean item score was used in ranking the professionals perception on rework triggers, and Kruskal-Wallis H test was used to identify the variables in which the professionals view varies. The study concluded that: contractor-related and design-related causes are the major categories of rework risks triggers. Unclear instruction to workers, Shortage of skilled supervisors, incomplete and inaccurate information are the predominant triggers of rework. The professionals view varies significantly on nine factors which cut across the four categories of rework triggers. It was recommended that there is need for clarity, effectiveness and timeliness of instruction and information dissemination among project participants, and the use of skilled and experienced professionals, skilled supervisors and proper implementation of quality management practices by both the design consultant and contractor throughout the project’s phases
