Subject to being insured are construction or installation works and construction related equipment. While the sum insured of the construction works equals the final cost of the construction works, the sum insured in the case of tools and temporary buildings is the acquisition cost less depreciation, i.e. the value of the property on that date.

When renovating, you should not forget that construction works may cause damage to the existing building. The existing building can be involved in the insurance contract being concluded, if the damage arising from construction is not compensated under the insurance contract belonging to the owner of the building. In addition to the aforementioned property insurance, liability insurance can be provided in the contract as well as the cost pertaining to overtime and night-time work due to the need to speed up work following a loss event.

Depending on the nature of the construction work, the contract may include a specific object of construction or works which are performed within a defined period of time, usually within one year. Usually "major" construction works are insured based on the object and "minor" construction works are insured pursuant to the principle of annual insurance. How to define "major" and "minor" is left for each company to decide.
