Steelray Delay Analyzer

Desktop delay-analysis software for Primavera P6 schedules. Vendor says it runs a fully automated half-step analysis using the Daily Progress Method, following AACE RP 29R-03 (MIP 3.4), on any number of XER update exports, and identifies and quantifies delays that moved the finish date, including concurrent and but-for delays. Outputs listed: an Overview Report splitting delays and accelerations into progress-related changes and schedule revisions per period, Period Detail Reports naming the activities that drove impact, longest-path change analysis, a contemporaneous critical path for each window, a progress-only schedule export, near-critical thresholds, an Excel export, and a 3D Gantt where you drag the data date. Vendor says it is chosen by delay experts and expert witnesses in claims disputes (vendor claim). Steelray also sells Project Analyzer (MS Project quality), Analyzer for P6 (Steelray and DCMA checks) and Project Viewer. The site does not describe AI.
