The Bauhauptgewerbe — how construction differs

Germany’s main construction trades run on social and tariff machinery that nothing else in this repo shares. A reader who understands the Handwerk or industrial picture and assumes construction works the same way will get the important parts wrong: how holiday is earned, what the minimum wage is, what happens in winter, and who the employer legally is.

This file exists so the individual trade profiles do not each explain it badly.

Bauhaupt- vs. Baunebengewerbe

Examples English Tariff world
Bauhauptgewerbe — structural work Maurer, Beton- und Stahlbetonbauer, Zimmerer, Straßenbauer, Gerüstbauer, Dachdecker* BRTV-Bau, SOKA-BAU, Bau-Mindestlohn
Baunebengewerbe / Ausbaugewerbe — finishing and building services Elektroniker EGT, SHK, Maler, Fliesenleger, Raumausstatter Electrician Own sector agreements; some have their own AEntG minimum

* Dachdecker and Gerüstbauer have their own sector agreements and their own AEntG-declared minimum wage, separate from the Bau one. They sit in this world structurally but not under the same paper. Check the agreement named in the contract, not the trade.

The repo’s two existing trades are both Ausbau. That is the gap this file and the §5a profiles close.

SOKA-BAU — holiday that travels between employers

The single most unusual institution in German working life, and the one that most surprises people arriving from another country or another sector.

Construction employment is discontinuous: projects end, firms lay off, workers move. Under the normal rules that would mean holiday entitlement resetting every time, and the six-month waiting period for full entitlement starting again.

So the sector pooled it. SOKA-BAU (the Sozialkassen der Bauwirtschaft — ULAK and ZVK) collects a percentage levy on every employer’s gross payroll and administers:

  • Urlaubskasse — your holiday entitlement and holiday pay accrue to you across the whole industry, not to a job. Change employer and the days come with you. Leave the industry, or leave Germany, and you can have the accrued balance paid out.
  • Berufsbildung — the levy also funds the sector’s Ausbildung, which is why construction apprenticeships are comparatively well paid and why a third year is commonly spent in a training centre (ÜBA) rather than on site.
  • Zusatzversorgung (ZVK) — a supplementary pension on top of the statutory one.

Participation is not optional and not negotiable: the Sozialkassenverfahren is declared generally binding (allgemeinverbindlich) under the AEntG, so it binds every employer in the sector, including foreign firms posting workers to German sites.

Practical consequences

  • Your payslip will show SOKA deductions and your holiday will be administered off-site. This is normal.
  • Keep your SOKA-BAU number. It is the thread that ties entitlement across employers.
  • If you work a season in German construction and leave, claim the balance — a meaningful sum goes unclaimed every year by workers who return home not knowing it exists.

BRTV-Bau — the framework agreement

The Bundesrahmentarifvertrag für das Baugewerbe is the sector’s framework: working time, wage groups, site allowances, notice, and the rules the Sozialkassen sit on. Pay itself is set in separate, regionally split wage agreements — West, East and Berlin have historically differed, with convergence being a long-running negotiating issue.

Two features worth knowing before signing:

  • Arbeitszeitkorridor / Jahresarbeitszeit. Construction is permitted to work long summer weeks and short winter ones against a working-time account, within an annual frame. Overtime is often banked rather than paid. Check how the account is settled and what happens to a positive balance if you leave.
  • Fahrtkosten, Verpflegungszuschuss, Auslösung — travel time, meal money and away-site allowances are tariff entitlements, not employer generosity. On Montage they can be a substantial share of take-home pay, and being partly tax-free (Spesen) they are worth more than the same euro of wage. The pay table does not capture them.

The Bau-Mindestlohn — a minimum above the minimum

Construction has a sector minimum wage set by AEntG declaration, sitting above the statutory Mindestlohn, in two wage groups:

Group Work
Lohngruppe 1 Unskilled site work — Bauhelfer
Lohngruppe 2 Skilled craft work — a qualified Facharbeiter rate; West only, historically

Both are perishable figures and are not quoted here — they are renegotiated on their own cycle. Check the current values at soka-bau.de or with the Zoll’s FKS pages before relying on a number.

Two things follow from it being an AEntG minimum rather than a company agreement:

  1. It applies to every worker on a German construction site regardless of where the employer is based or which country’s law the contract names.
  2. Enforcement is by the Finanzkontrolle Schwarzarbeit (FKS) — the customs unit staffed by the Zollbeamte profiled in this repo. Site checks are real and routine, and construction is their primary beat.

Winter — an employment model, not a season

Site work stops or slows when the ground freezes. Germany does not handle this by laying people off; it funds the gap, so that firms keep crews on the books through the winter.

Instrument What it does
Saison-Kurzarbeitergeld Wage replacement from the Bundesagentur für Arbeit for weather- and order-related downtime in the Schlechtwetterzeit (December–March)
Zuschuss-Wintergeld / Mehraufwands-Wintergeld Supplements funded from the Winterbeschäftigungsumlage, a levy on employers and employees, administered via SOKA-BAU
Working-time account Hours banked in summer are drawn down first, before the state instruments start

What this means for you: a winter with reduced or zero site hours is expected and paid for, and your contract should not end because of it. If an employer proposes a “seasonal” termination each autumn and rehiring each spring, that is a real warning sign — the sector has an entire funded apparatus designed to make that unnecessary, and the practice shifts the cost onto you and the unemployment insurance.

Posted workers — who your employer actually is

Construction is where EU posting (Entsendung) concentrates. A worker employed by a Polish, Romanian or Portuguese firm can be sent to a German site while remaining employed under that firm’s contract and, for up to 24 months, that country’s social insurance (the A1 certificate).

What still applies to them, under the AEntG and the Posted Workers Directive:

  • the Bau-Mindestlohn
  • the SOKA-BAU holiday scheme
  • German working-time, health-and-safety and site rules

What does not: German employment protection in general, and the German social-insurance system.

This is also, documentedly, where the sector’s worst exploitation sits — subcontracting chains several firms deep, accommodation deducted from wages, hours unrecorded, and entitlements that exist on paper and not in the bank. Nachunternehmerhaftung is the legal counterweight: the main contractor is liable for a subcontractor’s unpaid minimum wages and SOKA contributions, which is why main contractors police their chains.

If you are posted rather than locally employed, know which it is. It changes your pension, your health cover, and who you complain to.

BG BAU — accident insurance, and why it is prominent here

Every German employee is covered by a Berufsgenossenschaft; in construction it is BG BAU, and it is more visible than its equivalents elsewhere because the sector’s accident and occupational-disease numbers demand it. Falls from height dominate the fatality statistics, and the long-tail diseases — asbestos, silica dust, noise, and the knee damage that sends tilers and floorers into early Berufsunfähigkeit — are a large share of Germany’s recognised occupational-disease claims.

Consequences on site: Absturzsicherung rules enforced hard, mandatory PPE, the Baustellenverordnung requiring a safety coordinator (SiGeKo) on multi-contractor sites, and dust-suppression obligations that are checked.

Cover is automatic, employer-funded, and applies from the first hour — including to posted workers, and including where the employment itself turns out to be undeclared.

What to check before signing a construction contract

  1. Which agreement — BRTV-Bau, or the Dachdecker / Gerüstbauer / Ausbau agreement?
  2. Which Lohngruppe, and does it match the work you will actually do?
  3. SOKA-BAU number issued, and holiday administered through the Urlaubskasse?
  4. Working-time account — how is a balance settled on leaving?
  5. Montage terms — Fahrtzeit, Auslösung, accommodation: who pays and is it deducted?
  6. Employed or posted? If posted, which country’s social insurance, and is there an A1?
