The intelligence standard for project schedules
Open-source schedule intelligence platform — from validation to prediction to cost-schedule integration. Built for schedulers, project controls professionals, and forensic delay analysts: transparent, auditable, free.
Problem
01.Schedule intelligence tools split into two camps: expensive enterprise suites (Acumen Fuse, Primavera Risk Analysis) priced for owners and contractors with budgets — and fragmented open-source utilities that cover one analysis dimension at a time. Forensic delay analysis, EVM, ML-based duration prediction, and standards-traceable validation in a single transparent stack didn't exist.
Approach
02.Methodology library where every analysis engine traces back to a published standard (AACE Recommended Practices, DCMA 14-Point Assessment, SCL Delay & Disruption Protocol, GAO Schedule Assessment Guide). Layered: XER + MS Project XML parsing → DCMA validation → CPM + float trends → Time Impact Analysis → EVM + S-Curve → Monte Carlo QSRA → ML duration prediction (RF + GB ensemble per Gondia 2021 / AbdElMottaleb 2025) → Schedule Health Score → narrative reports. Custom hand-crafted SVG Schedule Viewer (zero external chart deps).
Impact
03.v0.1.0 → v4.3.0 production releases. 48 analysis engines + 1 export module. 22 Claude MCP tools (FastMCP). 1,679+ backend tests + Vitest + Playwright E2E. 129 API endpoints across 25 routers. 55 SvelteKit frontend pages. P6 XER round-trip write-back fidelity. $0/month infra (Cloudflare + Supabase free tiers).
