Building Technical Regulation (TEK17) – Structure and Documentation Throughout the Entire Project

TEK17 (Building Regulations) sets requirements for construction works to be designed and executed so that they are safe, healthy, environmentally sound, and fit for their intended purpose. The regulations are function-based and largely define what must be achieved—rather than exactly how. 

This means that each project must be able to document and demonstrate that the requirements have been met. 

A key part of TEK17 is ensuring that buildings are safe with regard to, among other things:

• fire safety

• moisture and water

• structural integrity and material performance

To document this, projects must have control over construction products, Declarations of Performance (DoP), documentation for indoor air emissions, etc. and any deviations that arise during the project.

Both Cobuilder Collaborate and Cobuilder Supply play a role in ensuring that documentation is available, up to date, and traceable throughout the entire project.

TEK17 § 3-1 requires that construction products used in a building are documented and that the documentation demonstrates the product’s suitability for its intended use by referring to the EU Construction Products Regulation (CPR), for example.

In practice, this means the project must be able to:

• Reference valid Declarations of Performance (DoP) or other product documentation

• Manage deviations between requirements, designed solutions, and delivered products

• Document clarifications and changes

With Cobuilder Collaborate, contractors and designers can manage DoP deviations and product documentation in a structured way throughout the project. This provides better traceability between requirements, products, and deliveries, and makes it easier to document compliance during inspections and handover.

For manufacturers and suppliers, Cobuilder Supply helps ensure that correct and up-to-date product documentation is collected and made available to the projects that need it.

TEK17 § 9-2 addresses requirements related to hazardous substances. This means projects must have control over which chemicals and products are used in the building, and which documentation applies.

In practice, this includes:

• Safety Data Sheets (SDS)

• Chemical information linked to products and deliveries

• Access to correct and up-to-date documentation

With Cobuilder Collaborate, projects can collect and manage SDS and chemical documentation across deliveries, ensuring the right information is available when needed—during construction, and inspection.

At the same time, Cobuilder Supply makes it easier for manufacturers and suppliers to share updated SDS and chemical documentation directly with projects.

TEK17 § 17-1 sets requirements for documenting greenhouse gas emissions from material use in construction works.

This requires access to correct and structured environmental data, especially EPDs, that can be linked to actual products and deliveries in the project.

Cobuilder supports this work through:

• Structured use of EPD data

• Structured use of generic LCA data from databases like Boverket, ÖKOBAUDAT etc.

• Improved data quality for greenhouse gas calculations

• Reduced manual work in data collection and follow-up

FDV and documentation deviations related to material choices and sustainability can be managed in Cobuilder Collaborate, supported by product and environmental data and documentation maintained in Cobuilder Supply.

The legal responsibility for compliance with TEK17 is distributed across the applicant, designers and contractors.

In practice, this often means:

• Building owners, contractors and designers are responsible for collecting, managing, and documenting compliance

• Manufacturers and suppliers must deliver correct and up-to-date regulatory documentation

Cobuilder Collaborate helps building owners, contractors and designers track, collect, and document the necessary evidence to demonstrate TEK17 compliance.

Cobuilder Supply gives manufacturers and suppliers an efficient way to collect regulatory documentation in one place, keep it updated, and share accurate information with projects.

TEK17 sets requirements for construction works in areas such as safety, fire, environment, and energy. In practice, follow-up and documentation require the a lot of  effort—and carry  risk.

Cobuilder supports projects in working more systematically with TEK17, enabling continuous compliance tracking and ensuring documentation is available when it is needed.
