Smart Retrofitting
Delivery without the risk of heavy contracting.
The delivery stage. NESTIUM acts as Technology General Contractor and Technology PMO — managing the project logic, solution selection, partner coordination and quality of outcome, without taking on the full risk of classic general contracting from day one.
- Role
- Technology GC · PMO · owner-side lead
- Model
- Fee for management and integration
- Outcome
- Measurable change in building parameters
- Billing
- Monthly or by milestones
Pricing after the discovery call — scope depends on the size and condition of the asset.
What it is
Rather than entering a heavy general-contracting model with high fixed-cost risk from the outset, NESTIUM leads delivery as an integrator of the retrofit process and owner-side technical lead. We manage the project, the vendors and the quality — you keep control over the risk.
We earn primarily on the fee for contract management and technology integration, not on a material margin. This keeps our recommendations independent and your project under control.
Who it's for
- Clients with a ready modernisation plan after Value Engineering
- Owners wanting to avoid chaos between multiple contractors
- Asset managers requiring progress reporting and KPIs

What you get
| Document / output | Why it matters to you |
|---|---|
| Final Scope & Implementation Plan | A clear scope and schedule for delivery |
| Vendor Coordination Framework | Order across contractors and suppliers |
| Monthly Delivery Reporting | Control of project progress and risks |
| Commissioning / Acceptance Protocols | Confirmation of implementation quality |
| Post-Implementation KPI Snapshot | A first assessment of results after delivery |
Variants
Management, coordination and oversight of the retrofit contract (typically 10–15%).
Additional fee for solution architecture and system interoperability.
Margin on selected elements: dashboards, data layer, integration documentation.
Pricing after the discovery call — scope depends on the size and condition of the asset.
What you really buy
improved asset quality and control over risk
You buy coherence of execution, less chaos between vendors and greater certainty that the implementation will translate into data and measurable results.
What happens next
Delivery ends with the first measurement of results. So you're not left alone with the system, we move to Remote Building Operator — continuous monitoring and optimisation.
You don't have to decide everything at once.
Start with a 30-minute discovery call. We'll establish the state of the asset, the main risks and a sensible first step.
