# Government department: 80% faster contract review with AI

> UK central government department · Public Sector · AiRE (AI Rollout Engine) + QuantSpark Labs

A central government department was reviewing thousands of contracts manually for compliance with new procurement rules. We deployed ContractCube and reduced review time from weeks to hours.

- **80%** Faster review
- Engagement: 8 weeks
- Team: 3 engineers

## What was the problem?

A central government department was responsible for reviewing every supplier contract above £100k against a new set of procurement rules introduced in 2025. The volume was approximately 4,000 contracts a year, and the existing workflow involved a team of 12 procurement specialists reading each contract manually and filling in a 30-field assessment form.

The team was running six months behind. The Permanent Secretary needed the backlog cleared before the next NAO audit, and there was no realistic prospect of doing it manually in the time available.

## What did QuantSpark do?

We deployed ContractCube against the existing contract repository. The first four weeks were spent training the extraction model on the specific clause patterns the department cared about, with weekly review sessions with the procurement team to refine accuracy.

Once the model was performing above 95 percent accuracy on a held-out test set, we built a review interface that surfaced flagged contracts to the procurement specialists with the AI-extracted assessment pre-filled. The specialists reviewed the AI work rather than doing the work from scratch.

We also built a compliance dashboard for the Permanent Secretary that tracked progress against the backlog in real time.

## What changed?

Contract review time fell from approximately 4 hours per contract (manual) to 25 minutes per contract (AI-assisted review). The backlog was cleared in 11 weeks against the original projection of 9 months.

The department has since extended the system to cover ongoing contract management, including obligation tracking and renewal alerts. The specialists who previously spent their time on manual review have been redirected to supplier engagement and category strategy work.

> "The thing that surprised us was that the AI made our specialists better, not redundant. They could spot things in 25 minutes that they would have missed at the end of a four-hour read."
