The situation

The utility was executing a $340M+ grid modernization program under a 72-month state utility commission order. Over 2,000 pages of regulatory filings had to be manually reviewed to produce software requirement specifications—an expensive, workshop-heavy process outsourced to consultancies. 8 upstream source systems lacked documentation, and the true program state lived in PowerPoint decks.

What we built

In an 8-week engagement, we built a retrieval-augmented compliance and requirements platform inside the client's cloud. We synthesized vendor specs from public filings, established multi-query hybrid retrieval with purpose-built reranking, and implemented document generation subgraphs with 5 parallel judge evaluators (faithfulness gate ≥0.95).

Multi-query expansion & regulatory framework anchoring
Document generation subgraphs with strict section contracts
Faithfulness evaluation gate (≥0.95) blocking bad builds
Deterministically fenced retrieval to prevent prompt injection
Client-side engineer solo deployment in under 30 minutes
Handed off documentation library replacing paywalled vendor specs

Deploy Time

Delivered all 4 contracted workstreams on time, meeting composite score gates (>0.90) and faithfulness gates (>0.95). Replaced weeks of consultancy workshops with cited, natural-language Q&A and 1-click requirement spec generation. Proven 100% portable: a client engineer deployed a second clean environment solo in under 30 minutes.

If you only have half the outcomes, you get half the requirements... how do I make sure we have all the requirements and we're building the right things?
