Regular apprentice meetings, excursions and other events are organised to promote an active internal exchange of ideas and information.

Our apprentices frequently participate at the Swiss Championships for building services engineering and have been on the podium regularly in recent years. In 2012 and 2013, our apprentices even won the title. Currently10% of all Amstein + Walthert employees are apprentices.


Electrical design EFZ

As an electrical designer, you design electrical installations for buildings according to the needs of the client. Electrical designers are expected to have extensive know-how, which makes their work very interesting. They address issues relating to medium voltage, high voltage, low voltage, grounding, telephone engineering and security systems, and are expected to follow various standards relating to the prevention of personal injury, property damage and workplace accidents.

Working together with the client, electrical designers first record detailed accounts of electrical supply and infrastructure specifications. Using the specifications as a basis, the designers then draft pictorial diagrams. These are used to represent electrical systems and installations in simplified and illustrative form. Pictorial diagrams are drafted to represent various design components such as medium voltage, high voltage and grounding installations, as well as control, security, telephone and R/TV antenna systems.

The electrical installations and electrical panels are then precisely represented in the electrical plans. Using these documents and the architectural drawings as a basis, the installation plans are then represented via CAD systems. This includes the drawing of power distribution routes and the exact positioning of individual fixtures such as outlets, motion detectors and lights. The electricians who later work according to the plans at the construction site are thereby able to know exactly where the fixtures, pipes and other components are to be positioned.

Electrical designers are also responsible for dimensioning pipes and cable ducts so that the necessary cable and wires have enough space. The same applies to the appropriate dimensioning of cable and wire gauges, i.e. so that the necessary high voltage can be safely transmitted. This is an area in which the regulations designers learn in school and training programmes are applied. Other challenges include the design of power supply systems for entire residential or industrial complexes, transformer stations, public lighting installations, etc. 


Heating systems engineering EFZ

Heating system designers design heating systems and installations for buildings and thereby ensure a comfortable degree of heat.

Heating system designers understand the full range of heating systems, from simple room heating systems to heat pumps, alternative heating systems, district heating and processing installations. They are also able to determine the most appropriate source of heat from among a variety of sources such as ambient heat, natural gas, oil, electricity, coal and wood. They know all about the various building materials and how to factor in their properties. In the context of design, the use of renewable sources of energy is examined and deployed whenever possible in the interest of environmental protection.

Designers meet with architects and developers during the design phase to ascertain their wishes and specifications relating their heating systems.

The heating system designer then designs the heating systems according to the client's specifications and the structural and economic circumstances. The work also includes the drafting of cost calculations and comparisons and the submission of bids.

Heating system designers make all of the relevant calculations (e.g. heating needs) and draft the plans for the production and installation of the systems using CAD. Pictorial diagrams are also necessary to illustrate the basic function of the heating systems.


Ventilation systems engineering EFZ

Air is the medium that keeps us alive. We breathe it, smell it and feel it on our skin. Good air and a good ambient atmosphere make us feel better and allow us to reach higher levels of performance. Bad air can make us irritable and diminish our performance. However, the availability of good air is not a self-evident matter. Especially not inside of buildings.

The work carried out by ventilation system designers helps to ensure that the air in homes, offices, laboratories, restaurants, hotels and hospitals is good and healthy. In addition to this, they can also make important contributions to improved energy efficiency.

Ventilation system design begins with meetings with developers and architects. In this context, general decisions are made and basic conditions are defined. Further meetings take place during the design phase between the various specialists and the project management. Ventilation system designers know all about the various types of ventilation systems, including their advantages and disadvantages. In addition to technical aspects, ventilation systems are also expected to meet aesthetic criteria, i.e. whenever their installation will leave them visible.

The dimensions of the ventilation ducts and accompanying fixtures are determined during the planning phase. The system can then be represented in the relevant drafting programme on the basis of the components and the architectural plans.

Ventilation system designers never work alone on a project. They draft ventilation designs on plans they receive from architects. In situations in which preferred designs are prevented by space constraints, for instance, the designers need to work out a solution directly with the architect. Moreover, projects will always include the participation of heating, plumbing and electrical designers. Using meeting results and the plans submitted by these other designers, ventilation designers aim to route their systems through buildings without clashing with other systems.

The installation work can begin when all of the system components have been accounted for and the ventilation system is in alignment with the other systems. This means that a subcontractor is selected to install the system. The plans are submitted to the developer and are then forwarded to the construction site. All of the ideas and clarifications that went into the design can now be implemented. As a ventilation system designer, it is very nice to experience the on-site installation of systems you may have been working on for months or even years.

Ventilation system designers face the challenges of storing their system components in the relevant facilities and, for instance, moving large ducts through the building. Ventilation systems are also sometimes required to meet special requirements for special applications such as: large kitchens, laboratories, computing centres and garages. Good general technical skills and creativity are often required to handle such tasks.


Plumbing systems engineering EFZ

Plumbing system designers design plumbing systems for buildings and thereby make an important contribution to hygiene and comfort. The scope of plumbing system design also includes sprinkler systems and special gases, for instance, in the case of medical device installations and gas extinguishing systems.

In the capacity of consultant to the developers and architects, plumbing system designers are expected to know the applicable standards and requirements, and to ensure compliance with respect to them. The planners know all about the available plumbing systems, from the simple plumbing installations appropriate for single-family homes to the complex systems that are installed in industrial plants, hospitals, computing centres and banks. An excellent understanding of the various building materials and their properties is essential for successful plumbing system design. Plumbing system designers also know the complete range of fixtures offered by the manufacturers of plumbing fittings.

Designers meet with architects and developers during the design phase to ascertain their wishes and specifications relating the plumbing system. The basic plan is then worked out in the context of a pilot project according to the specifications and adapted as appropriate to the structural and economic circumstances.

Cost calculations and cost comparisons are drafted and environmentally appropriate alternatives (e.g. rain water management systems, solar collector systems and heat recovery systems) are also presented. The work is by no means restricted to supplying buildings with water. Important contributions can also be made for our future, including energy and resource conservation.

The plumbing system designer then moves onward to the detailed design stage. All of the calculations for the installation are made and the plans are drafted using CAD for submission to the building authority, to component producers and installers.
