PrimaViewer

Overview

PrimaViewer opens Primavera P6 schedules in a browser for everyone who has to read them but does not hold a P6 licence - owners, subcontractors, executives and field teams. It reads XER files straight through, shows the WBS, activities and Gantt with costs, resources and relationships, compares two revisions of the same schedule, and lets people write progress back to the scheduler without ever altering the file.

The challenge

Primavera P6 licences are expensive and thinly spread, so the people who most need to read a schedule usually cannot open one. The scheduler ends up exporting PDFs for every question, revisions are compared by eye, progress arrives by email, and years of POBS records quietly bloat the XER until it crawls on load.

Our solution

We delivered a web application that treats the XER as a first-class document. Activities, the work breakdown structure, the critical path, milestones, calendars, relationships, activity codes, notebook topics and steps are all browsable, with a Gantt view and look-ahead filters for a chosen calendar window. Schedule Comparison takes an original and an updated XER and reports exactly what moved - added and deleted activities, duration, date, cost, constraint, relationship, resource assignment and code changes - to PDF or Excel. Progress entry captures actual start and finish, percent complete, remaining duration and notes as a report for the scheduler, leaving the source XER untouched, and the XER Cleaner strips POBS data so files load fast in P6 again.
