Engineering consultancy · Basel · since 2003 Technology that works discreetly.
Climate, energy and integrated building services engineering as well as laboratory and industrial planning – all from a single source. Optimal room conditions and economically efficient operating facilities are the result of advanced technology.
Our approach
Fewer interfaces. Lower costs. Higher quality. Every saving goes straight to your bottom line.
Discreet technology
One building, four uses, seven trades, one point of contact
Calm from the outside. Behind it, kilometres of ducts, pipes and cables – invisible when they are planned properly.
Office, laboratory, cleanroom, data centre: four climates, four pressure levels, four safety concepts under one roof.
- Ventilation
- Heating
- Refrigeration
- Plumbing
- Electrical
- Building automation
- Laboratory & media
We bring all trades together – fewer interfaces, lower costs, higher quality. Manufacturer-neutral, from the idea through to commissioning.
Services
One core.
Three roles.
Building services and laboratories are our core. Within it, we plan, manage projects and advise – depending on what your project needs at the time.
01Plan
We do it.
From concept through to commissioning – building services and laboratory as one whole.
02Manage
We lead it.
Holding trades, schedules and contracts together – on the client's side or within the planning team.
03Advise
We review it.
An independent view before the decision, when things get stuck, and during operation.
For general planners, general and total contractors
You plan the building.
We plan the technology.
As specialist planners in your team, we take on building services and laboratory with one responsible person – manufacturer-neutral, coordinated and aligned with your schedule.
- Plumbing and electrical as separate roles in the team
- One point of contact for all trades
- Start small: interface check before the contract
