Activities
The critical-path Gantt where the schedule is actually built — a virtualised table and timeline that computes your dates from logic, calendars and constraints instead of letting you type them.
Who it is for. Planners building and updating schedules throughout the day, with keyboard shortcuts for routine edits and XER import and export for exchanging schedules with clients and delivery partners.
What it is for
A schedule needs dates that respond to logic, calendars, constraints and progress. When those calculations are disconnected from daily edits, planners cannot reliably see the critical path, available float or the effect of an update.
Build durations from quantities and production rates, then use the same schedule for DCMA checks, crash analysis, forensic delay analysis and Monte Carlo. Planning and analysis work together in the browser, with no export step or client install.

What it does
Every line below is in the product today.
A real forward and backward pass
Total and free float per activity, including negative float where it belongs.
Eight constraint types, with typed violations
ASAP, ALAP, start and finish no-earlier and no-later, must-start-on and must-finish-on — raising warnings or errors rather than moving silently.
Relationship codes normalised defensively
All four relationship types with leads and lags, accepting short-form, long-form and legacy numeric XER codes.
Duration from production rate
Quantity divided by crew output, with the rate per day, week or month, on working or calendar days, aware of the activity’s own calendar.
Float-path tracing
From the selected activity — backward, forward, both, or the free-float path — with stepped float cutoffs and a show-only-this-path mode.
Keyboard shortcuts for daily planning
Field-level undo and redo, fill down, copy and paste of activities, and select all keep routine schedule edits moving.
Several projects in one Gantt
Projects open as sibling roots with read-only anchors pinned so only the active one flexes, and inter-project logic pulled from an external-links model.
A non-destructive what-if sandbox
Clones the schedule, captures current dates as the scenario baseline, and reschedules live against the real engine without touching the database.
Virtualised, and it stays smooth
Only the rows near the viewport render, and zoom tracks the mouse wheel smoothly even on schedules with thousands of activities.
It reads and writes with
WBS
Build the deliverable hierarchy once, drag unassigned activities onto it, and save the whole structure as a reusable template for the next project.
Network
See the logic instead of the bars — an activity-on-node diagram in four layouts with the critical path highlighted and float on every card.
CP Crash
Find the cheapest way to pull the finish date in, see what each day actually costs, and know the exact date the critical path moves to a different chain.
DCMA Checks
Run the DCMA 14-point assessment against your live schedule, a stored project, or a client’s XER — before they run it on you.
See it on your own schedule.
Send an XER before the call and we will import it and show you Activities running against your data.
