Engineering in Excellence

Electrical planning, lighting design, energy efficiency, alternative energy sources, interface coordination, safety checks, status analyses, lightning protection: these are not just buzzwords. They are our passion, our mission. We advise you on all your projects - professionally, independently and neutrally. We plan the desired installations for you and coordinate the efficient execution of your order, analyse existing installations and carry out appropriate safety checks. Without question, we are also your competent partner in phases 31 to 53 of SIA 108.


Building Information Modeling

We use Building Information Modeling (BIM) software to optimise the planning, execution and management of buildings. All partners involved in the construction digitally record the relevant building data. The project is built „virtually“ before we turn it into
reality - and we can already identify and eliminate problems in the planning stages. 


Neutral electrical planning

The basis of worry-free electrical infrastructure is careful planning. Our planning and design work - including transparent financial management and professional advice - ensures that you receive and pay for exactly what you need.


Lighting design

Light helps create experiences. Whether in a living space, bathroom, kitchen, office or factory: the right atmosphere is only created through good lighting design. Our experience, creativity and know-how ensure that we deliver unique lighting solutions that provide much enjoyment.


Energy efficiency

The implementation of legal requirements for energy efficiency plays a major role in technical building equipment today. Energy consumption is reduced to a minimum with the right electrical planning, modern controls and optimal electrical systems.


Alternative energy sources

Our extensive experience enables us to offer other innovative technologies to reduce operating and energy costs - such as photovoltaic systems which include appropriate financing models. We are at your side right from the planning and calculation of yield through to the completion of your project.


Interface coordination

Thanks to state-of-the-art innovative technology, you benefit from electrical systems that are extremely easy to operate. Networked building services communicate and work together. This interaction makes it easier for your facility management team to operate and significantly reduces maintenance costs.


Safety checks

The increasing complexity and high security requirements of modern buildings and systems require optimal collaboration between planner and business owner. Risks arise through interfaces that are not (or are insufficiently) recognised and coordinated. We implement integral safety checks to check the functionality and the interaction of all systems. You will also receive a written record of the results.


Lightning protection

The design and planning of a lightning protection system must be carried out by a licensed specialist company. The respective protection classes and zones, as well as the applicable SEV Guidelines and cantonal fire protection regulations, must be observed in connection with the initial concept, groundwork and preliminary planning.

Teilphasen SIA 108

Partial phases according to SIA108

At the beginning of the project, our partial services in accordance with SIA 108/112 offer a flexible and cost-effective way to support you. Object-neutral advice or unbiased expert assessments regarding building approvals relieve you of difficult decision-making. As a building owner, architect or client, you can benefit greatly from timing the release of all project phases as partial services, according to SIA 108/112.


Feasibility and status analysis

In order to complete status analyses, we inspect and formulate the "current" and "target" conditions of a building, including any requirements for innovative electrical planning. On the basis of this research, target concepts for solution proposals and progress can be developed for your project. A neutral expert assessment provides security in critical circumstances or contributes to decision-making and peace of mind.

Our process

Our goals are your requirements

Clearly structured processes and professional planning ensure that the workload is optimised, while the risk of error is simultaneously minimised. To your advantage.

Needs analysis

You explain your requirements, wishes and goals. We advise you on suitable solutions, and deliver them.


Based on the needs analysis, we draw up coherent, sustainable concepts and present them to you.


Based on your chosen concept, we plan and calculate with you to design the ideal solution.


We implement the chosen design with expertise and dedication, and accompany you until your project is successfully completed.
