Schedule forensics
you can defend.

Fragnet independently recomputes the schedule — DCMA health, delay forensics, and probabilistic risk — with every number traceable to a frozen input and a cited method.

The difference

Most tools re-present P6. Fragnet recomputes it.

A real forward/backward-pass CPM engine derives its own early/late dates, float, and longest path — so manipulation and hidden logic surface instead of being echoed back to you.

Re-presentation tools

  • Display P6's stored dates and float, as-is
  • Can't independently verify the critical path
  • No real Time Impact Analysis
  • Outputs that don't survive a hostile expert

Fragnet

  • Recomputes early/late dates, total float & longest path
  • Splices a fragnet and re-runs the driving path (AACE 52R-06)
  • Seeded, reproducible Monte-Carlo risk (QSRA)
  • Every result traceable to a hashed input & cited method
The analysis suite

One upload. The whole forensic workbench.

01 · HEALTH

DCMA 14-point + grade

Full 14-point assessment with CPLI/BEI and a roll-up A–F quality grade, against a generic or agency rule-pack.

02 · FORENSICS

Time Impact Analysis

Splice a fragnet into the logic, recompute the driving path, and auto-write the AACE 52R-06 methodology narrative.

03 · RISK

QSRA Monte-Carlo

Probabilistic finish dates with duration correlation and a seeded, reproducible simulation you can re-run to the number.

04 · COMPARE

Schedule Delta

Pair & multi-version diff — added, deleted, duration, date, float, logic and lag changes, plus forecast slip.

05 · EARLY WARNING

Float erosion & alerts

Track float burn and milestone breaches across updates before they become the claim.

06 · FORENSICS+

Windows & as-built

Windows analysis, collapsed-as-built and concurrency/pacing — forensic methods, computed not asserted.

07 · PERFORMANCE

EVM & S-curves

Earned-value metrics and progress S-curves derived from the recomputed schedule.

08 · WHAT-IF

Sandbox & bottleneck

Test logic and duration changes safely; merge-bias and bottleneck detection expose the real constraints.

09 · OUTPUT

11 branded PDF reports

DCMA, TIA, QSRA, EVM, Windows and volatility — plus the full claims set and a compiled, submission-ready claim package. Every one court-ready, cited, and reproducible.

Delay claims & forensics

We’re not called Fragnet for nothing.

A fragnet is the fragment-net you splice into a schedule to model a delay — the decisive move in a Time Impact Analysis, and the one thing legacy tools concede they can’t do. We built the whole platform around it. Claims aren’t a bolt-on here; they’re the reason Fragnet exists — every method computed from the recomputed schedule, not asserted, and every number traceable to a hashed input and a cited method so it holds up under cross-examination.

01 · DETECT

Find the delay

Windows analysis, as-planned-vs-as-built and float erosion surface the slip and where it happened — computed, not echoed back from P6.

02 · MODEL

Splice the fragnet

TIA (AACE 52R-06), impacted-as-planned and collapsed-as-built — additive and subtractive, on a real forward/backward-pass CPM engine that honors calendars and constraints.

03 · ATTRIBUTE

Assign responsibility

Owner / contractor / concurrent classification with a day-by-day concurrency apportionment — the split that decides what’s actually compensable.

04 · QUANTIFY

Put a number on it

Measured-mile productivity loss, extended field & home-office overhead (Eichleay), and liquidated-damages / delay-cost calculators.

05 · NARRATE

Write the story

The per-event narrative builder weaves the schedule facts with your referenced exhibits into a cited, defensible account — you supply the judgment, it supplies the rigor.

06 · PACKAGE

Ship the claim

Compile every event, method summary and a consolidated exhibit index into one bound, submission-ready claim package — the deliverable a claim is filed as.

◆ End to end, from the first slipped day to the filed claim — deterministic, cited, and built to survive a hostile expert.

Why it holds up

Auditable by design, not as an afterthought.

Traceability is the feature. Every analysis can be reproduced and defended line by line.

  • Immutable snapshotsEvery uploaded update is frozen as a read-only, versioned snapshot — nothing overwrites.
  • Input hashing & provenanceSource files are SHA-256 hashed; every result names the exact input it came from.
  • Versioned methodologyEngine and rule-pack versions are pinned to each analysis, so the math is never ambiguous.
  • Append-only audit trailUploads and analyses are logged immutably — a defensible chain of custody for the record.
