The Swedish construction industry: actors, rules and how to enter the market

The construction industry in Sweden: size and role in the economy

Construction is one of Sweden’s largest industries. It builds homes, schools, hospitals, offices, roads, railways and utility networks — and maintains and rebuilds what already exists. In the broad sense it is the whole built-environment sector: clients and property owners, contractors and trades, architects and engineers, material suppliers, authorities and training providers.

According to Statistics Sweden’s (SCB) labour force surveys, which the contractors’ federation Byggföretagen reports in its industry facts, construction employs several hundred thousand people. On top of that come those working in design, building-material manufacturing and property management. Construction investment — new build and refurbishment of housing, commercial premises and infrastructure — makes up a significant share of Sweden’s gross fixed investment, and it swings more sharply with the economic cycle and interest rates than the economy as a whole. Current figures are published by SCB and in Byggföretagen’s forecast report Byggkonjunkturen.

Three features shape the Swedish industry and explain much of how it works:

• **Project form.** Almost all construction happens in temporary projects with a unique team — which is why standard contracts and shared specification systems carry so much weight.
• **Long supply chains.** A main contractor can have dozens of subcontractors (UE), who engage their own; quality, safety and integrity must hold through the chain.
• **Strong regulation.** The Planning and Building Act (PBL, 2010:900), Boverket’s building regulations, the Work Environment Act and the Public Procurement Act (LOU) govern what is built and how.

This guide gives the overview: who the actors are, the shared language they use, the rules that apply, where the industry is heading — and what a foreign company needs to sort out before it can work here. How an individual project runs step by step, from idea and zoning to completion certificate and operation, is covered in our guide to the construction process in Sweden.

Market segments: buildings, civil works, refurbishment and services

The industry is traditionally divided into segments with different clients, contracts, skills and sensitivity to the economic cycle. Many companies work in several segments, but the boundaries explain why the market can move out of step — civil works can grow while housebuilding stands still.

Building construction — housing

New multi-family housing (rental apartments and tenant-owned apartments, bostadsrätter) and single-family houses. This is the most cyclical segment: when interest rates and building costs rise and household demand falls, tenant-owned projects are the first to stop. Clients are private developers, municipal housing companies, tenant-owner associations being formed and — for houses — private individuals buying through house manufacturers.

Building construction — non-residential

Offices, retail, warehousing and logistics, industry, hotels and public buildings such as schools, preschools, healthcare facilities, elderly care homes, police stations and universities. Public buildings are often commissioned by municipalities, regions and state property companies and procured under LOU, which makes demand more stable but the process more formal.

Civil engineering and infrastructure

Roads, railways, metro, bridges, ports, water and sewerage networks, energy and power grids, groundworks and foundations. The largest single client is the Swedish Transport Administration (Trafikverket), but municipalities, municipal water companies, energy companies and industry are also major clients. Civil works are largely driven by political decisions on infrastructure and by the transition of the energy system, and projects are often long and technically complex. Contracts and specifications normally follow AMA Anläggning.

ROT — repair, refurbishment and extension

A large and growing share of work is in the existing stock: pipe replacement in the 1960s–70s “Million Programme” estates, energy upgrades, extensions, fit-outs, facade and roof renovation, and bathrooms for households. ROT is less cyclical than new build and dominated by small and mid-sized firms. Households can claim the ROT tax deduction (ROT-avdrag) on labour costs.

Building services

Electrical, plumbing and heating, ventilation, sprinklers, controls, lifts and cooling — a growing share of construction cost, in both new build and service. Installatörsföretagen represents the employers and publishes industry rules.

The actors: who commissions, who builds, who regulates

To understand the Swedish industry you need to be able to place the actors. Broadly there are five groups — clients, contractors, consultants, suppliers and authorities — plus the organisations that bring them together.

Clients and the byggherre

Under PBL the byggherre (developer/client) is the party that, on its own account, carries out or commissions building work. The byggherre bears ultimate responsibility for the project meeting the legal requirements, and must appoint the kontrollansvarig (KA, certified quality controller) and the building work environment coordinators (BAS-P and BAS-U). Clients fall into two camps:

• **Public clients:** municipalities and their companies, regions, Trafikverket (state roads and railways), state property companies such as Akademiska Hus, Specialfastigheter and the National Property Board, and the municipal housing companies. They procure under LOU or, for utilities, LUF.
• **Private clients:** property companies, developers that buy land and build for sale, industrial companies, tenant-owner associations and private individuals.

Client competence is one of the biggest single factors behind successful projects. A capable client states clear requirements, chooses a suitable contract type and manages risk deliberately — see the early stages of the construction process.

Contractors — from large groups to sole traders

Contractors carry out the work on site. The structure is clearly pyramid-shaped: a few large groups, a larger number of regional and mid-sized builders, and a very large number of small companies — many with fewer than ten employees.

• **Large contractors.** Skanska, NCC and Peab (building and civil works), JM (residential development) and Norwegian-origin Veidekke run the most complex projects and often set the standard for safety, digitalisation and climate work.
• **Mid-sized and regional builders.** Much of the regional building work, often with close ties to local clients.
• **Small companies and trades.** Carpenters, painters, tilers, plumbers, electricians and groundworks firms, often as subcontractors or in the ROT segment.

Between them runs the subcontractor chain: the main contractor (general or design-and-build contractor) engages underentreprenörer (UE, subcontractors) for different trades and packages, who in turn may engage their own. A long chain brings flexibility and specialist skills but makes quality, safety and integrity harder to control. Many clients therefore limit the number of tiers in the chain by contract — something foreign subcontractors should check before pricing.

Architects and engineering consultants

Design is carried out by architects and engineering consultants — structural, building services, geotechnical, fire, acoustic, environmental and energy specialists, plus project and construction managers — from large international groups to small specialist practices. Appointments are normally under ABK 09.

Material suppliers and merchants

Manufacturers of concrete, steel, timber, plasterboard, insulation, windows, services products and prefabricated elements, plus merchants and plant hire. Most of a new building’s climate impact arises in material manufacturing, and products covered by a harmonised standard must be CE marked with a declaration of performance.

Authorities

• **Boverket** (National Board of Housing, Building and Planning) — issues the building regulations and guidance on PBL, climate declarations and energy performance certificates.
• **Arbetsmiljöverket** (Swedish Work Environment Authority) — supervises health and safety, issues the AFS regulations and receives posted-worker notifications.
• **Municipal building committees (byggnadsnämnder)** — decide on permits, issue start notices and completion certificates and supervise compliance with PBL; the municipality also adopts detailed plans.
• **Lantmäteriet** — property formation, the property register and geodata.
• **County administrative boards (länsstyrelser)** — hear appeals against municipal PBL decisions and protect national interests in planning.
• **Others:** Skatteverket, the Swedish Tax Agency (staff registers, F-tax, ROT deduction), the National Agency for Public Procurement, the Swedish Competition Authority, the Civil Contingencies Agency and the National Electrical Safety Board.

Industry organisations and trade unions

• **Byggföretagen** (Swedish Construction Federation) — industry and employers’ organisation for contractors, formerly Sveriges Byggindustrier. Signs collective agreements and publishes forecasts and industry facts.
• **Innovationsföretagen** — organisation for architecture and engineering consultancies.
• **Byggnads** — the trade union for, among others, carpenters, concrete workers, bricklayers, floor layers and civil works operatives.
• **Unionen and Sveriges Ingenjörer** — the largest unions for salaried staff and engineers in the industry, for example supervisors, site managers and estimators.

Shared industry institutions

• **Svensk Byggtjänst** — owned by the industry; publishes AMA, the BSAB system/CoClass, the standard contracts and much of the industry’s reference literature.
• **BKK** (Byggandets Kontraktskommitté) — produces the standard conditions AB 04, ABT 06 and ABK 09 through cooperation between the client, contractor and consultant sides.
• **SBUF, Smart Built Environment and IQ Samhällsbyggnad** — fund and run industry research, digitalisation and development networks.

Standards and the shared language: AMA, BSAB, AB 04 and the building regulations

A client in Luleå and a subcontractor from Malmö can start working together without negotiating every detail because the industry has a shared language: specification systems, standard contracts, technical standards and industry rules. Learn these acronyms early — they appear in every Swedish set of tender documents, and foreign firms that skip them tend to misprice.

AMA — the reference specification

AMA (Allmän material- och arbetsbeskrivning, general materials and workmanship specification) is a reference work of requirements on materials, workmanship and inspection that the project’s technical specifications refer to. It comes in several parts — including AMA Hus, AMA Anläggning, AMA VVS & Kyla, AMA EL and AMA Funktion — and is published by Svensk Byggtjänst in new editions every few years. Alongside it are AMA AF, which provides templates for the administrative provisions, and RA (advice and guidance) to support specification writers. The project specification states which codes apply and adds project-specific requirements. There is no direct international equivalent: think of it as a national master specification whose clauses become contractual simply by being referenced.

BSAB and CoClass

BSAB is the Swedish classification system that structures the AMA codes; CoClass is its successor for digital information management and BIM. In practice both are used side by side.

The standard contracts: AB 04, ABT 06 and ABK 09

• **AB 04** — general conditions for build-only contracts, where the client is responsible for design.
• **ABT 06** — general conditions for design-and-build contracts, where the contractor also designs.
• **ABK 09** — general conditions for architecture and engineering consultancy.
• In addition there are, among others, ABU 07/ABTU 07 for subcontracts and ABM 07 for material purchases.

The conditions are negotiated between clients and contractors within BKK and regarded as balanced — so rewriting them in the AF section without understanding the consequences is risky. BKK has spent several years on a comprehensive revision, with the working titles AB 25 and ABPU 25 as successors to AB 04 and ABT 06 respectively. As of October 2026 the new conditions have not been published. Whatever happens, the contract referred to in the tender documents is always the one that applies to the project.

Building regulations and Eurocodes

Boverket’s building regulations are now split into one regulation per essential requirement (see our building regulations hub, in Swedish, or Boverket’s English overview). The BFS 2024 series applies from 1 July 2025: load-bearing capacity (BFS 2024:6, replacing EKS, BFS 2011:10), fire safety (2024:7), hygiene, health and environment (2024:8), safety in use (2024:9), noise (2024:10), suitability of dwellings (2024:11), accessibility (2024:12) and plots (2024:13). Energy efficiency has its own regulation, BFS 2026:9, from 1 October 2026, when BBR (BFS 2011:6, last edition BBR 31) was repealed in full. Older projects may still be assessed against BBR and EKS under the transitional provisions. Structures are designed to the Eurocodes (SS-EN 1990–1999) with Swedish national choices.

Wet rooms and water installations

For bathrooms and water installations, three industry rule sets — Byggkeramikrådet’s BBV, GVK’s Säkra Våtrum and Säker Vatten — define good workmanship in practice, and insurers and clients often require authorisation under them.

ID06

ID06 is the industry system for identification on construction sites: a personal card showing who the person is and which company they work for. The card is used for access control and to meet the requirement for an electronic staff register. ID06 also offers registration of skills and training, so clients can check that staff are qualified for, say, hot work or scaffolding. More on what this means for foreign firms below.

How projects are organised and financed

The contract type decides who designs, who bears the risk of errors in the documents and how much the client can control the details. The most common forms in Sweden:

• **Utförandeentreprenad (build-only, AB 04)** — the client designs and is responsible for the documents; the contractor builds to them. Can be procured as a general contract (generalentreprenad) or as split contracts.
• **Totalentreprenad (design and build, ABT 06)** — the contractor designs and builds based on the client’s functional requirements; the client gives up detailed control in exchange for clearer responsibility.
• **Partnering and collaboration (samverkan)** — client, contractor and consultants work in a joint organisation with open books and shared incentives, often on complex projects or framework agreements.
• **Payment forms:** fixed price, cost reimbursement (with or without target price and incentive), or unit-rate schedules for remeasured work.

How the choice is made and how procurement is carried out is covered in detail in the procurement section of our construction process guide. Variations (ÄTA) are where much of the commercial outcome is decided — see our guide to change order management.

Financing

Private projects are financed with equity and bank loans. Tenant-owned housing normally requires a share of apartments to be pre-sold before starting — so weak sales hit starts directly — while rental housing depends on long-term cash flow and is sensitive to rates and costs. Public projects are funded through budgets, municipal companies through loans with municipal guarantees and major infrastructure through the national transport plan. Contractors finance running costs between invoices and often provide a bank or parent company guarantee.

Health and safety: one of Sweden’s most dangerous industries

Year after year, construction is among the Swedish industries with the most fatal and serious occupational accidents, according to the Swedish Work Environment Authority’s statistics. Falls from height, collapses, being struck by vehicles and machinery, falling objects and electrical accidents dominate. Add musculoskeletal injuries, noise, vibration and exposure to silica dust, asbestos and isocyanates in refurbishment. Health and safety is therefore not a side activity but part of every project plan.

The regulatory framework

The foundation is the Work Environment Act (1977:1160) and the Authority’s AFS regulations, restructured on 1 January 2025: design and building work environment coordination is now in AFS 2023:3, and the old rules on building and civil engineering work (AFS 1999:3) have been replaced by the new structure. Technical requirements for things like scaffolding and fall protection are in the new regulations on the design of workplaces and work equipment. Always read the current regulation on av.se before citing a section. The principles follow the EU framework; the role names and documents are Swedish.

BAS-P and BAS-U

For every building and civil engineering project the byggherre must appoint a suitable building work environment coordinator for planning and design (BAS-P) and one for execution (BAS-U). BAS-P coordinates health and safety in design and ensures a work environment plan (arbetsmiljöplan) is drawn up when required; BAS-U coordinates the work on site and keeps the plan up to date. AFS 2023:3 sets out the competence requirements for coordinators — training, experience and suitability in relation to the project’s size, complexity and risks — and the byggherre must make sure the coordinators are actually able to carry out their tasks.

Everyday safety practice

• A risk assessment before every activity with significant risks — our guide to construction risk assessment shows a practical method.
• Method statements (arbetsberedningar) in which the crew goes through how, with what and in what order the work will be done.
• Regular safety inspections (skyddsronder) with the safety representative, and follow-up of actions.
• Induction of everyone who enters the site, including subcontractors and suppliers.
• Reporting and investigation of near misses — they are free lessons before the accident.

Working in Sweden as a foreign construction company

Foreign subcontractors and posted workers are a common sight on large Swedish sites, but the entry requirements are real, enforced on site and mostly administered in Swedish. This is a starting point, not legal or tax advice: details depend on your company form, home country and how long you will work here, so check with the authorities named and, for anything substantial, a Swedish adviser.

Company registration and F-tax

A foreign company can work in Sweden either from its home-country entity or through a Swedish presence — a registered branch (filial) or a Swedish limited company (aktiebolag), both registered with Bolagsverket, the Companies Registration Office. Which route is required or sensible depends on the scope and duration of your activities; verksamt.se, the joint government portal for businesses, explains the options in English.

Whatever the form, the key registration for construction work is with Skatteverket, the Swedish Tax Agency. Swedish clients and main contractors will ask for proof of approval for F-tax (F-skatt), which shows that the company itself is responsible for its taxes. If a contractor is not approved for F-tax, the paying customer must as a rule withhold tax from payments for work — so in practice you will struggle to get work without it. Foreign companies apply with a dedicated form from Skatteverket. Expect to also deal with VAT, employer registration where relevant and the question of whether your activity creates a permanent establishment in Sweden. Requirements on foreign entities have been tightened in recent years, so apply in good time and keep your reporting up to date.

Posted workers (utstationering)

If you send your own employees to work temporarily in Sweden, the Posting of Workers Act (1999:678) applies. The employer must report the posting to the Swedish Work Environment Authority through its e-service “Report a posting” (anmälan om utstationering), and appoint a contact person in Sweden who can receive documents on the employer’s behalf and be reached by authorities and trade unions throughout the posting. The Swedish customer has its own obligations: if it does not receive proof that the posting has been reported, it must notify the Authority. The employer must also comply with Swedish rules on the work environment, working hours, holidays and discrimination during the posting. Exemptions, deadlines and documentation requirements are set out on the Authority’s posting pages in English — read them before the first worker travels. Social security for posted EU workers is usually documented with an A1 certificate from the home country.

Staff register (personalliggare) and ID06

On Swedish construction sites, an electronic staff register must be kept under the Tax Procedure Act. The byggherre must report the building site to Skatteverket before work starts, and the start and end of every shift worked on the site must be recorded for every person. Skatteverket makes unannounced inspections, and the purpose is to counter undeclared work and unfair competition. According to Skatteverket’s English guidance, the developer provides the register equipment while each contractor records its own people; very small projects with a total cost of no more than four base amounts are exempt. The developer can transfer all of its obligations to a contractor that independently answers for carrying out the work — typically the general or design-and-build contractor — but only by written agreement.

The ID06 card is the industry’s way of meeting the staff-register requirement in practice, and most main contractors require it for everyone on site. Your company needs to be connected to the ID06 system before your workers can get cards, so build that into your mobilisation plan. Information is available on id06.se.

Collective agreements and Byggavtalet

Sweden has no statutory minimum wage. Pay and many working conditions are set by collective agreements between employers’ organisations and trade unions. For construction workers the main agreement is Byggavtalet, between Byggföretagen and the Byggnads union; building services trades have their own agreements. Swedish law does not oblige a foreign employer to sign a collective agreement, but within the limits of the Posting of Workers Act unions can take industrial action to secure agreed minimum terms for posted workers, and many clients and main contractors require terms in line with collective agreements in their contracts — as public clients increasingly do under LOU. Ask the Work Environment Authority’s posting service, Byggföretagen or Byggnads which terms apply to your workers before you price the job.

Checklist before your first Swedish site

• Decide your company form in Sweden and, if needed, register a branch or company with Bolagsverket.
• Apply for F-tax approval with Skatteverket and sort out VAT and employer registration.
• Report postings to the Work Environment Authority and appoint a Swedish contact person.
• Connect the company to ID06 and get cards for every worker who will be on site.
• Clarify which collective-agreement terms the client or main contractor requires.
• Make sure supervisors can work with a Swedish work environment plan, safety inspections and AFS requirements — or bring in a Swedish-speaking coordinator.
• Read the contract’s AF section and the referenced AB 04/ABT 06 or ABU 07/ABTU 07 conditions in full; see our construction process guide for how they fit together.

Trends shaping the Swedish construction industry in 2026

From housing slump to cautious recovery

After record years around 2017 and a peak in 2021, housebuilding fell sharply in 2023 as rates and costs rose and tenant-owned sales stalled; starts hit their lowest levels in many years and bankruptcies rose, while civil works and refurbishment held up better. For 2025 and 2026 Byggföretagen describes a cautious recovery from low levels, held back by high costs and weak rental demand. Follow SCB’s housing-start statistics and Byggföretagen’s forecasts.

Climate requirements and the climate declaration

Since 2022 a climate declaration (klimatdeklaration) has been required for most new buildings, covering construction-stage impact from materials, transport and construction. Boverket’s proposed limit values from 1 July 2025 were not introduced; instead development is coordinated with the recast EU Energy Performance of Buildings Directive (EPBD), pointing to extended life-cycle assessment (LCA) around 2028 and limit values around 2030. The EPBD will also bring zero-emission requirements for new buildings and stricter rules for the existing stock; how and when is being decided in the ongoing Swedish implementation. Many clients, including Trafikverket, already set their own climate requirements.

Circular construction

Reuse of building products, pre-demolition inventories, waste sorting and design for disassembly are moving from pilots to standard requirements. Refurbishing instead of demolishing and rebuilding is often the largest single climate saving.

Industrialised construction and prefabrication

More and more is made in factories: precast concrete, timber volumetric modules, CLT frames and bathroom pods — shorter programmes and better quality, at the price of early design freeze and supplier dependence. Multi-storey timber construction has grown strongly over the past decade.

Digitalisation, BIM and AI

BIM is standard on larger projects for coordination, clash detection and quantity take-off. AI is increasingly used to read and compare tender documents, draft specifications and minutes, review documents and analyse risk — see our guide to AI for construction.

New building regulations

The move from BBR and EKS to the BFS 2024 series and BFS 2026:9 is the biggest change to the building regulations in more than a decade. The rules are more purely performance-based, which means new references in control plans, specifications and fire safety reports.

Public procurement

Public clients spend very large sums under LOU each year. The trend is towards evaluating quality and sustainability rather than price alone, more collaborative forms, employment terms in line with collective agreements, and a new procurement law under review.

Unfair competition and work-related crime

Construction is one of the industries where Swedish authorities see most work-related crime: undeclared work, tax schemes, exploitation of foreign labour and infiltration through long subcontractor chains. Countermeasures include staff registers, ID06, limits on subcontractor tiers, collective-agreement requirements and F-tax checks. Expect thorough checks of your company before you are accepted into a supply chain.

Skills supply

Retirements and rising demand for digital and climate skills make skills supply a major challenge; shortages of experienced project managers, site managers, structural engineers, installers and certified quality controllers persisted even during the downturn. Women remain a small minority among tradespeople, though a much larger share of salaried staff, architects and engineers. See our guide to construction lessons learned on keeping knowledge in the organisation.

Roles, careers and training routes

The trades — carpenters, concrete workers, bricklayers, tilers, painters, electricians, plumbers, plant operators — are the core of the industry, surrounded by salaried roles in design, production and operations:

• **Projektledare (project manager)** — leads the project for client or contractor: time, cost and quality.
• **Projekteringsledare (design manager)** — coordinates the design team.
• **Platschef (site manager)** — the contractor’s head on site.
• **Byggledare (client’s site representative)** — monitors on the client’s behalf that the contractor builds according to the contract.
• **Kalkylingenjör (cost estimator)** — prices bids and budgets.
• **KMA-samordnare (QEHS coordinator)** — drives quality, environment and health and safety work in projects and companies.
• **BAS-P and BAS-U** — the building work environment coordinators the developer appoints for design and execution.
• **Kontrollansvarig (KA, certified quality controller)** — helps the developer with the PBL control plan and monitors that it is followed.
• **Arkitekt and konstruktör (architect and structural engineer)** — design the building and size its structure.

Salaries vary widely between roles, regions and experience. Current pay statistics by occupation are available in SCB’s Lönesök (in Swedish), and the unions (Byggnads, Unionen, Sveriges Ingenjörer, Sveriges Arkitekter) publish their own pay statistics for members.

Training routes

• **Upper secondary vocational programmes** — building and construction, electrical and HVAC, followed by an apprenticeship.
• **Higher vocational education (yrkeshögskola)** — one to two years with work placements, for example for supervisors, estimators or BIM coordinators.
• **Engineering degrees** — högskoleingenjör (three years, 180 credits) or civilingenjör (five years, 300 credits) in building, civil engineering or construction management.
• **Architecture** — five years (300 credits) at, among others, KTH, Chalmers, LTH and Umeå University.
• **Certifications and further training** — for example certification as kontrollansvarig, BAS courses, hot work, scaffolding, fall protection and courses in AMA, AB 04/ABT 06 and LOU.

Foreign professionals should note that some roles require Swedish certification (the kontrollansvarig, for example), and that practical production experience counts for a great deal — even graduates often benefit from having worked on site. Swedish language skills are a practical requirement for most site and client-facing roles.

Tips for newcomers to the Swedish market

• **Learn the language of the industry first.** AMA codes, the AF section, ÄTA, egenkontroll, slutbesiktning, BAS-U — the acronyms are many but recur on every project. Read a real Swedish set of tender documents from start to finish.
• **Understand the contract type on your project.** Whether it is build-only or design-and-build decides who is responsible for what — and so what you can claim and what you risk. Read AB 04 or ABT 06 chapter by chapter.
• **Document as you go.** A site diary, signed self-inspections and minuted decisions protect you when something is questioned later. Our guide to a construction quality control plan shows how to structure the checks.
• **Take health and safety seriously from day one.** Ask about the risk assessment, use the protective equipment and speak up when something looks wrong. Everyone has the right — and the duty — to point out risks.
• **Sort out the paperwork before you mobilise.** F-tax, posting notifications, ID06 and collective-agreement terms are checked on site — see the section for foreign companies.
