Map Renovation Dependencies, Earliest Starts and Schedule Float

How to Use This Tool

Turn user-defined tasks and predecessors into an auditable critical-path draft. Build a renovation dependency schedule from task durations, flag missing or circular links, calculate earliest starts and float, and export a timeline.

The work this page finishes

Renovation lists hide sequencing: a delayed rough-in can move inspection and drywall while an independent finish may still retain float. For Renovation Timeline, the row-preserving workspace makes a correction repeatable without rebuilding a prompt or transmitting the source file.

Deterministic workflow

Topologically order valid task-predecessor links, calculate earliest start/finish with a forward pass, then calculate project-relative float with a backward pass. For Renovation Timeline, this page accepts at most 5,000 records and 2 MB of text; rejected items retain their row references while valid items remain available.

Why a dedicated interface helps

Use zero-float tasks as coordination priorities and revise durations as facts change; the output is a transparent draft, not a completion promise. For Renovation Timeline, immediate recalculation and a stable export are useful when the same rule must be applied consistently across a list instead of explained one item at a time.

Assumptions

• Durations are working-day estimates on one common calendar.
• Predecessor labels match task labels exactly.
• Dependencies are finish-to-start with no lag.

For Renovation Timeline, retain the original source until the destination accepts the result; processing stays in this tab, although the device and installed extensions remain part of the user's security boundary.

Limitations and review boundary

It does not infer construction logic, calendars, crews, permits, lead times, resource leveling, local code or contractor availability. For Renovation Timeline, no supplied URL is requested and no pasted markup or code is executed; output is inserted through text-only DOM operations.

Verification and provenance

The implementation was checked against U.S. GAO Schedule Assessment Guide on 2026-08-26, with fixtures for a known answer, an invalid input and a batch-specific edge condition. The six-task example branches after drywall and reports the critical sequence plus the shorter branch's float.
