The Venezuelan Petrochemical Industry, in 1990, did not have a database of its own holding man-hours works for the construction field. Such information was of great need, given the beginning of the petrochemical plants expansion in the country. The aim of this study is to show how the performer of this study planned, coordinated and designed a Construction Man-hours Database in a petrochemical plant (PEQUIVEN, Zulia, El Tablazo), taking advantage of the referred business expansion, and which would also help estimate man-hours, in future projects, more accurately.
