ScheduleLens

ScheduleLens is a browser-based forensic analyser for a single construction or infrastructure programme. You upload a schedule file and get back a standards-anchored report in minutes, with nothing to install.

It reads the formats planners use: Primavera P6 (XER and XML), Microsoft Project (XML and MPP), and Asta Powerproject (PP) natively. Reading PP without an XER export is something most competing tools cannot do.

Three report types:

Schedule Health checks one programme against the DCMA 14-point assessment, traces the critical path, ranks float paths, runs logic, constraint and calendar checks, forecasts progress, and grades the schedule A to F.

Schedule Comparison takes two versions of the same programme, such as baseline versus current, and shows what changed, why the completion date moved, and a three-number delay decomposition.

Series analysis takes several successive updates of one programme and tracks how delay accrued across them.

Every number in a report is computed by a deterministic engine. The analysis itself is not performed by AI. An off-the-shelf language model only writes the already-computed findings into readable prose, grounded in verbatim excerpts of the standards each finding cites. It never invents figures.

Update-integrity checks are the most differentiated part of the product. Across successive contractor submissions it flags mechanical evidence of schedule manipulation: a Retained Logic to Progress Override switch that moves the critical path without touching an activity, slip concealed by shaved durations, recorded actual dates that changed after they were first reported, critical-path churn, and forced Expected Finish dates. Each flag states the evidence and leaves judgement to the reader.

Standards anchoring: DCMA 14-point (PAM 200.1 thresholds), an AACE RP 29R-03-aligned observational method, and an SCL Protocol Appendix B records-adequacy assessment on comparison reports, with a methodology appendix citing the standard behind each finding.

Subscribers also get a Project dashboard that tracks one programme's snapshots over time, a multi-baseline timeline that measures each snapshot against the plan in force for its era, and two grounded conversational agents that answer read-only questions from the computed results.

Pricing is per report from $29, or subscriptions from $79 a month. An analysis runs before payment, so you see the DCMA headline and a sample of the findings from your own file before deciding. The uploaded source file is deleted after processing.

ScheduleLens is built for one programme and its own versions over time, not a portfolio of distinct projects.
