Aligned governance
De-risk the handback of your concession or PPP.
Simeo is the trusted third party that brings clarity to the relationship between grantor and concessionaire. One shared reference of asset condition, one shared methodology, from the first year of the contract to the day the assets are handed back.
One contract, two parties, one source of truth.
A concession or public-private partnership binds a public grantor and a private operator around the same infrastructure for decades. Each party needs its own answers from the same assets, and the contract between them stands or falls on how condition is measured. Simeo gives both sides the same reference.
Grantors & granting authorities
You own the asset and grant its build, operation and maintenance for a fixed term. You need continuous, independent visibility that the infrastructure you will take back is being maintained to the standard the contract promises.
Concessionaires & operators
You finance, build, operate and maintain the infrastructure, then hand it back. You need to plan renewal spend efficiently across the term and demonstrate contract compliance without end-of-term surprises.
The contract between you
Handback clauses (in French, remise en bon état of the biens de retour) are where concessions turn contentious. A condition reference shared by both parties removes the ambiguity that fuels disputes.
What grantor and concessionaire do together in Simeo.
Build and maintain the renewal plan
Build and update the multi-year asset renewal plan on shared, structured condition data, instead of two parallel spreadsheets that disagree by construction.
Optimise infrastructure condition
Targeted preventive maintenance actions, prioritised by risk and criticality, keep the infrastructure on the agreed condition trajectory at the lowest whole-life cost.
Guarantee good condition to handback
A tool and methodology shared between grantor and concessionaire make end-of-contract condition a monitored fact rather than a late-stage negotiation.
How Simeo works across the life of the contract.
Shared reference
One condition baseline both parties trust
Asset condition, criticality and risk live in one structured model that grantor and concessionaire both read. Field inspections feed the same inventory, so there is no 'your survey versus our survey'.
Plan
A renewal plan that stays current across the term
Build the renewal plan against the shared baseline and update it as condition evolves. Compare intervention scenarios under budget and risk constraints, so both parties see the consequences of every arbitrage.
Handback
Evidence that the assets come back in good condition
Every maintenance and renewal action links back to the asset, its condition data and the shared methodology. As the contract term approaches, handback readiness is a report, not a reconstruction.
Handback by negotiation vs handback by evidence.
Traditional
- Each party runs its own condition surveys
- Renewal plan revisited only at crisis points
- Condition disputes surface in the final years
- Handback negotiated from contested evidence
- Institutional memory fades across a multi-decade term
With Simeo by Oxand
- One condition reference shared by both parties
- Living renewal plan, updated as condition changes
- Condition trajectory monitored from day one
- Handback readiness tracked as a standing indicator
- Asset knowledge held in the platform, not in leaving heads
Frequently asked questions
What is handback in a concession or PPP contract?
Handback (in French, remise en bon état of the biens de retour) is the contractual obligation to return infrastructure assets to the grantor in an agreed condition at the end of a concession or public-private partnership. Disputes typically arise because the two parties measure condition differently; a shared reference removes that ambiguity.
How does Simeo help the grantor?
Simeo gives the granting authority continuous, structured visibility of asset condition throughout the term, against the same reference the concessionaire plans with. The grantor can verify that maintenance and renewal keep the infrastructure on the contracted trajectory, years before handback becomes urgent.
How does Simeo help the concessionaire?
The concessionaire plans renewal and preventive maintenance on evidence, prioritised by risk and criticality, and demonstrates contract compliance from the same data the grantor reads. That means efficient spend across the term and a handback defended by records rather than by negotiation.
When in the contract lifecycle should Simeo be introduced?
The shared baseline delivers most value when it exists from the start of the contract, but Simeo is also introduced mid-term, typically ahead of a contract review or the final handback horizon, by building the condition reference from inventory and inspection data first.
What integrations are available?
CMMS (Maximo, Infor EAM, CARL Software, SAP), ERP, GIS, BIM, IoT and SCADA, and the major business intelligence stacks via REST and GraphQL APIs.
Where does the data live?
Default: Azure France region (EU residency, ISO 27001, NIS2-aligned). Self-hosted Kubernetes is available for operators with strict isolation requirements.
