Structural calculations in Groningen

Reviewing existing investigations alongside a new renovation plan

Where can you find local information?

Groningen distinguishes between the former municipalities of Groningen, Haren and Ten Boer when providing file access. For the former municipality of Groningen, it lists records from 1878–October 2010 at Groninger Archieven. Follow the route for your address; today’s municipal name is not always the archive name.

Reviewing existing investigations alongside a new renovation plan

Do you already have an inspection, damage or repair report? Supply it in full and explain which works have since been completed. An earlier report may address a different question from your proposed renovation. Clarify what was investigated then and what you want to change now. No conclusion about your building is drawn from the region alone.

These points help you prepare. They are not an assessment of a particular property.

Renovation — concept detail, not for construction
Educational illustration; not a photograph or calculation for a local project.

Three actions to prepare your enquiry

  1. Check the former municipality when selecting archive records.
  2. Include complete investigation reports and attachments.
  3. Record which recommended works were actually completed.

What scope fits your proposal?

Send the records you have found together with your proposed changes. We discuss the calculations, structural drawings and any additional information required. An archive record describes a documented situation; its correspondence with the current building needs assessment. The quotation defines the work and price.

Check permits and other consents separately for the project address. Our structural approval guarantee covers additions to our own documents within the agreed scope. The municipality decides on planning and permit approval.
