Infrastructure & PPP

Diagnostics for infrastructure practitioners

Short, structured screens for the questions that come before a commitment: whether a project is worth developing, whether a contract is being managed, whether an idea is defined well enough to test. Each one is willing to tell you no.

Across every stage

AI opportunity 3 tools

Where AI fits in infrastructure work, and where it does not. Most problems these tools examine turn out to need process, data, integration or analytics instead.

01Before approval

Pre-feasibility 10 tools

Appraisal before a project is approved for development: whether the need is real, whether demand supports it, whether it is affordable, how risk should sit between the parties, and whether the environment around it can deliver.

02Before anyone relies on the model

Financial model review 1 tool

Before a lender, an authority or a board relies on a project-finance model: where formulas break, where numbers were typed over formulas, whether saved errors reach the results, whether the rate inputs are plausible and whether the model matches its term sheet. The model is read in your browser and never uploaded. An optional AI second opinion sends only the extracts you approve to Anthropic, using your own API key.

03After signature

Contract management 7 tools

After signature, for the decades that follow: whether the management regime exists, what a variation does, what a renegotiation would cost, and whether anyone is ready for a dispute.

04Existing assets

Asset strategy 1 tool

What to do with infrastructure that already exists: monetization, recycling, divestment, concession renewal and the readiness questions that decide whether any of them is worth taking to market.

Video explainers 3 series

The mechanisms behind the tools, explained on The Infrastructure Brief — how a PPP is actually put together, and what it looks like when one does not hold. Three series, running from first principles to post-mortem.

Series 1
PPP for Beginners A chaptered course, in order: what a PPP is, how it is structured and procured, and how it is managed through to termination and handback.
Series 2
Case studies One project, one lesson. Lesotho’s Queen Mamohato hospital, the Manila water concessions, Vietnam’s solar boom, the end of the UK’s PFI programme.
Series 3
Deep dives One mechanism, examined closely, usually through a project where it failed: availability deductions, the discount rate, demand risk, refinancing gain.
