Approval of a site supervisor in charge must be applied for before starting the construction work or preparatory work, such as excavation, quarrying, pile-driving or felling of trees. A site supervisor in charge is also required for demolition work to be performed on a renovation site subject to a permit.
Approval of a specialist supervisor must be applied for before starting construction work in the specialist field in question.

The party starting the construction project is responsible for verifying the validity of the construction products used and documenting it in the construction work inspection document.
The validity of a construction product means that the product, by virtue of its characteristics, can be used for the intended application and meets the technical requirements set for the application by authorities.
Read more about checking the validity of products on the Building Information page (in Finnish).
The party starting the construction project is responsible for moisture control on the construction site.

Supervision by the developer
The developer can apply for the right to supervise the construction itself if the building is not a residential building. Supervision will be carried out in accordance with the approved supervision plan. When approving the supervision plan, Building Control decides where no regulatory supervision is required.
Upon application, Building Control may allow the author of the construction plan or account or another sufficiently skilled person employed by the party starting the construction project to inspect that the construction work conforms with the plan. The inspect carried out must be certified by a marking on the documents.
The building control authority may require an external inspection, where the applicant must provide an expert opinion on whether the planned solution or construction meets the requirements set for it by law. The party starting the construction project bears the resulting costs.
