Hiring a building draughtsman in Switzerland: the method

Recruitment starts before the job advert: Draughtsman CFC and Building Services Designer CFC are distinct professions, while each CFC specialisation targets a different candidate pool. The main talent pipeline comes from four-year dual apprenticeships and vocational schools, making in-house training a major recruitment advantage. Finally, a 90-minute practical test using real drawings can better distinguish candidates by assessing standards compliance and model coordination rather than simply measuring speed.

Three decisions to make before writing the advert

Most drawn-out recruitments in this field do not fail at selection. They fail at defining the requirement, and the symptom is always the same: a high volume of off-target applications costing two to three weeks of screening for nothing.

Draughtsman CFC or building services designer

This is the sector's most expensive confusion, and it appears in a large share of French-speaking Swiss adverts. The draughtsman CFC produces drawings for buildings or structures under the direction of an architect or engineer. The building services designer CFC sizes and plans heating, ventilation and sanitary installations. Two qualifications, two profiles, two salary grids.

Publishing an advert headed "draughtsman-designer" without stating the scope attracts both populations. The manual screening that follows is wasted time, and worse, the right candidate does not recognise themselves in the advert and does not apply. We set out both profiles in our analysis of the draftsperson and project designer in Switzerland.

Which CFC specialisation the post actually requires

The official title is Dessinateur/-trice CFC, with four specialisations. They are not interchangeable: a civil engineering draughtsman put on facade details will be slow and frustrated, and the reverse is equally true.

CFC specialisation	What the profile can do	Type of post	Pool availability in 2026
Architecture	Building design, construction details, facades, roofs	Architecture practices, general contractors	Tight: housing is driving demand
Civil engineering	Infrastructure, reinforced concrete, structures	Engineering offices, civil works	More accessible: segment flat in Q1
Interior architecture	Interior space planning	Specialist practices	Narrow pool, few qualified holders
Spatial planning	Urban planning, zoning	Local authorities, planning offices	Narrow pool, heavy regulatory component

Our position at Fed Engineering: if you are hesitating between two specialisations, the post is not defined. In the 2026 market the economics settle it for you -the Swiss Contractors' Association reports an order book up 14.6 % year on year and quarterly turnover up 5.6 %, driven by building work, while civil engineering was flat. An architecture-side post is therefore recruited in a tight market, a civil engineering post in a looser one.

The third decision: train or buy

The CFC is earned over four years of dual apprenticeship, three to four days in a design office and one to two days at vocational school. It is the standard entry route, and the only structural variable an office genuinely controls. A training office has an internal pool, knows each apprentice's real level, and recruits with no fee and no vacancy period. A non-training office buys at market price, in direct competition with those that train.

Where to find candidates when the pool bypasses the universities

This is the methodological difference from engineer recruitment. The channels that work for a university-trained profile are unproductive here, and vice versa.

Channel	Yield on a CFC profile	Note
Vocational schools and training centres	High	Direct relationship with teaching staff, visibility on upcoming cohorts
Network of training offices	High	Newly qualified apprentices not retained for lack of a post are immediately operational
Referrals from your own draughtsmen	High	A small, well-connected professional community in French-speaking Switzerland
General online advertising	Medium	High volume, weak targeting if the specialisation is not stated
Direct approach on professional networks	Low to medium	Less present and less responsive than engineering profiles
Candidates trained abroad	Variable	A foreign vocational qualification may be recognised by the State Secretariat; the profession is unregulated, so employers judge case by case

One point few offices exploit: the Confederation refunds 50 % of preparatory course fees for federal examinations, up to CHF 9,500 for a federal certificate and CHF 10,500 for an advanced diploma. Offering that route costs little and carries real weight against a competitor adding CHF 3,000 of base pay. One condition is absolute: the invoice must be issued in the candidate's name, never the company's, or the subsidy is lost.

The 90-minute test that separates a modeller from a coordinator

Two draughtsmen with identical CVs can be ten years apart in real value. An interview does not reveal it: vocabulary can be learned, practice cannot. This is the format we recommend to our design office clients, calibrated to run in half a morning without tying up the whole team.

Thirty minutes -working up a construction detail. Provide a hand-annotated sketch and ask for the finished detail. You are not assessing speed but discipline: complete dimensioning, correct drawing conventions, line weights and layer management.
Twenty minutes -spotting inconsistencies. Hand over a deliberately faulty drawing: dimensions that do not add up, a section level incompatible with the plan, a sill height contradicting itself across two views. A good draughtsman finds most of them. This is the most discriminating exercise in the test.
Twenty minutes -BIM discussion on file. Ask the candidate to open a test file in the exact software version they claim, and to talk through the model structure. You verify in passing that the stated command is real.
Twenty minutes -verbal debrief. Have the candidate explain the choices made in the first two exercises. Being able to justify a drawing decision to an architect is part of the job, not an extra.

The four questions that cannot be bluffed

They work because they are about team practice, not textbook knowledge. A candidate who has genuinely worked in a coordinated environment answers in thirty seconds; the others generalise.

Who writes the BIM execution plan on your projects, and have you read one in full?
What do you actually do when the building services model clashes with the structure?
What is the last software version you migrated, and what broke?
How are the office templates managed where you work now, and who maintains them?

The fourth is the most revealing. A modeller uses the templates; a higher-level profile maintains them. On the comparative value of testing in technical roles, our guide to recruiting engineers in Switzerland covers the wider selection framework.

The statutory timeline to build in before promising a date

This is where office management most often gets it wrong, and it has nothing to do with the quality of selection. Two delays are entirely outside the recruiter's control.

Constraint	Effect on the timeline	Room for manoeuvre
Vacancy reporting duty (art. 21a)	Five working days of exclusivity for the public employment service before any public advertising	None. Check the occupation group in the Check-Up tool before publishing
Candidate's notice period (art. 335c CO)	1 month in year one, 2 months from year two to nine, 3 months thereafter, to the end of a month	Only by agreement with the current employer
Signature date	Signing on the 2nd rather than the 30th of the previous month pushes the start back a full month	Complete, and it is the best lever available

In practice: allow four to five months between opening the post and the first day worked for a candidate who has been in place for several years. Promising a start date to a client or a project manager before seeing the candidate's contract is the surest way to have to retract it.

The real budget for the post, beyond the advertised salary

An experienced draughtsman on CHF 78,000 gross does not cost CHF 78,000. With employer contributions, the loaded salary cost reaches about CHF 89,000. Adding the BIM licence, the amortised workstation and continuing training, the full cost of the post approaches CHF 94,000 a year, a 1.21 multiplier on the advertised gross. Set against genuinely productive hours, once holiday and public holidays are stripped out, that is close to CHF 50 an hour.

That figure, not the gross, belongs in the budget before the post is opened -and it is also what allows a serious trade-off between a permanent hire, a fixed-term contract and an external service. Salary ranges by profile are set out in our building draughtsman job profile.

Frequently asked questions

Can you hire a draughtsman without a CFC?

The profession is unregulated, so legally yes. In practice, the absence of a CFC or recognised equivalent closes off most established design offices and complicates progression to a designer role. For an experienced profile without the qualification, validation of prior learning through the State Secretariat is the route to explore.

Should the advert require Revit or ArchiCAD?

Require the software your office actually uses, with the version. A competent draughtsman moves between tools in a few weeks, but the migration carries a productivity cost better taken on knowingly than discovered after hiring.

How many candidates should be seen for one post?

Three to four tested finalists are enough where the CFC specialisation and scope are properly defined in the advert. Beyond six, the problem is not the talent pool but the definition of the post.

Does hiring a cross-border draughtsman create particular difficulties?

Employer contributions are identical, since social insurance affiliation follows the place of work. The points to anticipate are withholding tax and the permit. If you go through an agency, it must hold the federal licence for any cross-border activity.

Permanent hire or temporary assignment?

Above roughly 1,500 hours a year on the same skill, a permanent post is markedly cheaper on a loaded hourly basis. Below that, or on a skill the team lacks such as model coordination, temporary hiring buys immediate availability and transfers the under-utilisation risk.
