Questions by topic
Enquiries & collaboration
Contact usHow does the enquiry process work?
You call or write to us. We look at the property on site, and you then receive a quotation with a schedule and a named contact person.
Who is my point of contact?
One person per project – from the site visit to acceptance. You can reach the relevant division head on +41 44 435 10 50 or at kontakt@technikpartner.ch.
Where does Technik Partner operate?
Technik Partner is headquartered in Zurich. Our teams work throughout Switzerland – for network operators, developers, property owners, property managers, data centre operators and businesses.
What does the acquisition by Circet change?
Customers keep the same contacts: the management team continues to lead the business, and the teams remain in place. Since 29 July 2026, Technik Partner has been part of the Circet Group.
Electrical engineering & energy
More on electrical engineering & energyDo I need a safety certificate after the installation?
Yes. The Low-Voltage Installation Ordinance (NIV) requires a safety certificate for new installations and modifications. You receive it from us after acceptance.
Is the incoming supply sufficient for charging stations in our underground car park?
Usually, yes – with load management that distributes the available power across the charging points. The site survey shows whether the main incoming supply needs to be upgraded.
Is solar PV with battery storage worthwhile?
Yes, if an energy management system controls generation, storage and loads: solar power flows first to the loads currently running and into storage, then into the grid. We install and connect the systems.
Can you replace a main distribution board in an occupied building?
Yes, in stages, with interruptions announced in advance for each riser or floor. We provide the tenant notice.
Data centres & service
More on data centresWhat does “availability targets up to Tier IV” mean?
Tier I to IV are the Uptime Institute’s availability classes; Tier IV means fault-tolerant and concurrently maintainable. We design installations to the target you need – up to Tier IV. Certification applies only to a specific data centre and is awarded only by the Uptime Institute.
What is the difference between a UPS and a standby generator?
The UPS bridges interruptions of seconds to minutes. In a prolonged outage, the standby generator, usually diesel-powered, takes over. Together, they ensure a continuous supply.
What does cold-/hot-aisle containment achieve?
It separates the cold supply air in front of the racks from the warm exhaust air behind them, so that the two do not mix. This keeps the temperature at the racks constant and saves energy.
What does 24/7 service & maintenance cover?
Maintenance, fault service, repairs and support for data centres and critical installations – around the clock, for customers with a service contract. The scope and our availability are set out in the contract.
Fibre optics & FTTH
More on fibre optics & FTTHWhat is Network Level 4?
The in-building segment of the fibre network: from the building entry point (BEP) to the optical telecommunications outlet (OTO) in each unit. Technik Partner builds this segment across Switzerland – for network operators or directly for property owners and developers.
What is the OTO outlet and what do I need the OTO-ID for?
The OTO is the fibre outlet in your flat. You use its OTO-ID to order your subscription; your provider uses it to activate the connection.
Who commissions an NE4 in-building connection?
Usually the network operator as part of its network roll-out, often in consultation with the property owner or property manager. Property owners and property managers can also commission us directly, for example for retrofits or new builds.
As a tenant, do I need to be at home?
For the installation of the outlet in your flat, yes – you will receive advance notice of the appointment. Work at the building entry point and in the riser does not require you to be present.
How many fibres are installed per flat?
In Switzerland, the four-fibre model is common practice: four fibres per residential or commercial unit, so that several providers can connect via the same in-house cabling.
What happens after installation?
We test every fibre, document the OTO-ID and hand over the documentation to the network operator and the property manager. You then order your subscription from your provider, who activates the connection.
What records do I receive?
The final test report for each fibre and the documentation for each unit with its OTO-ID. Both are part of our handover.
Networks, telephony & security
More on IT & communicationsCopper or fibre in an office building?
Both: Cat 6A copper to the workstation, OM4 or OS2 fibre between floors and buildings. Our cabling is vendor-neutral, and we test and document every link.
We still have an old phone system – what now?
In Switzerland, telephony runs over IP. We migrate your system to IP or cloud telephony, port your numbers and train your team.
What does a video conferencing room need?
Display or projection, camera, microphone, speakers, the connection to your platform and a room control system that lets you operate the whole room centrally. We calibrate the room and train the users.
What do I need to bear in mind with video surveillance?
The Federal Act on Data Protection (FADP): a clear purpose, signage for the monitored areas, limited retention and access for authorised persons only. We plan the system accordingly and configure recording and access to match.
Job applications
More on the application processHow do I apply?
Send your CV and three sentences on what you can do to kontakt@technikpartner.ch, subject “Bewerbung”. You will then get to know us in Zurich or on a construction site.
Do I need prior experience in fibre installation?
Not necessarily. Trade or electrical training and a careful approach to work are the foundation; you will learn splicing and testing with our team.

- Standby generator
- Usually diesel-powered; takes over the supply during a prolonged grid outage.
- Tier I–IV
- Uptime Institute availability classes; the Institute certifies only specific data centres.
- Cold/hot aisle
- Rack layout that keeps the cold supply air in front of the racks separate from the warm exhaust air behind them.
