Check a schedule on a machine you don't control

Browser-based tools and a written reference for construction planners. Nothing installs. Nothing uploads. No macros to unblock, no Office bit-version to match, no admin rights required.

Every other P6 toolkit is an Excel add-in or a Windows executable. If your laptop is locked down — and most site laptops are — those never get past IT. Gridopedia runs in the browser tab you already have open, and the file you load never leaves your machine.

105 reference pages

223,769 words on float, logic, calendars, updating, earned value, reporting, delay and claims. Free to read, no paywall.

Nine schedule tools

DCMA health check, baseline submission check, three-file progress audit, XER to Excel, S-curves, WBS tables, longest path, out-of-sequence, logic integrity. In final testing.

What's coming, and when

One email when the first tool is published. Downloadable offline copies go to this list first.

What this does not do

So nobody wastes an afternoon finding out

Gridopedia reads, checks and reports. It does not write back to P6, repair databases, split activities or export XER files. If you need those, buy a proper desktop tool — they are good, and they are cheap.

Nothing here is legal or contractual advice. The rate tables are for sanity-checking a duration, not for evidence in a claim.
