This study sought to establish the impact of piping fabrication/installation management on the project deliverables of Umusadege hydrocarbon processing plant in Kwale, Delta State, Nigeria. Piping fabrication/installation management was dimensioned with four cardinal management processes which include project initiation, planning, execution and closure. While the deliverables were measured using As-built documentations and On-site activities. This gave rise to eight hypotheses which were tested using the Pearson’s Product Moment Correlation technique; aided by International Business Machine Statistical Product and Service Solutions (IBM SPSS) version 21.0 at the 0.05 level of significance. The analyses revealed that there is a strong significant relationship between the dimensions of piping fabrication/installation management and the measure of deliverables of the hydrocarbon processing plant. Based on this it was concluded that piping fabrication/installation management is an antecedent of the project deliverables of Umusadege central processing facility.
