eTaskMaker, by InterPlan Systems, is a front end planning and estimating tool that generates resource loaded project schedules ("fragnets") that can be exported to numerous project management software platforms.  eTaskMaker is bundled with a enxtensive estimating library for both routine (equipment cleaning, inspection and repair) and non-routine (piping demolition, fabrication and installation) work found in a typical refinery or petrochemical plant turnaround.
