Subcontractor Agreement – AB-U 07, Extra Work (ÄTA), Work Environment and Liability
Share
Short answer: A subcontractor agreement should link together scope, schedule, compensation, variations (ÄTA), quality, work environment, insurance, liability, and documentation. Standard terms such as AB-U 07 or ABT-U 07 do not apply automatically just because they are common in the industry – they must be incorporated into the agreement in a clear manner.
| Scope | Exactly which works, documents, and interfaces are included? |
| Variations (ÄTA) | Who is authorized to order changes, and how should they be priced and documented? |
| Time | Start, milestones, completion, and consequences of delay. |
| Work environment | Roles, coordination, work preparations, risks, and requirements for compliance with work environment regulations. |
Clearly refer to standard agreements
AB-U 07 and ABT-U 07 are standardized subcontracting terms often used in conjunction with other contract documents. If the parties want a standard agreement to apply, the reference should be explicit and the document hierarchy clear, especially if there are deviations or specific administrative provisions.
Scope and demarcation
Many construction disputes start with the question of whether a piece of work was included in the contract sum. Therefore, describe the scope of the construction work, drawings, technical specifications, design responsibility, and interfaces with other contractors.
Variation (ÄTA) works
The agreement should state who is authorized to order changes and how price and time consequences are to be approved. A clear written routine reduces the risk of work being performed without the parties agreeing on compensation.
Work environment and coordination
The subcontractor has employer liability for their staff, while the construction project may also be subject to coordination by the developer and the Work Environment Coordinator (Bas-U). AFS 2023:3 and other work environment regulations need to be considered alongside the project's work environment plan and site rules.
Contractor liability for wages
The Act (2018:1472) on contractor liability for wage claims applies to Swedish construction and civil engineering activities and may entail liability higher up the contracting chain when an employee of a subcontractor does not receive their wages. This is an important compliance issue when selecting and monitoring subcontractors.
Insurance, warranty, and defects
- requirements for liability insurance and proof of insurance,
- inspections, remedial work, and warranties,
- liability for damage to one's own and others' property,
- documentation, self-inspections, and "as-built" documents,
- final settlement and withholding of payment when agreed upon.

FAQ
Do AB-U 07 apply automatically?
No. Standard terms must be made part of the agreement through a clear reference or other incorporation.
Who is responsible for the work environment?
Several actors may have parallel obligations. The subcontractor has responsibility as an employer, while the developer and the construction work environment coordinator have specific coordination duties.
What is most important in a variation (ÄTA) routine?
That ordering authority, written procedures, pricing, and time consequences are clearly regulated before the variation work is performed.
