Focus of expert report

an expert report by defective workmanship describes the pathology detected, its technical origin, its relationship with the execution carried out and the necessary corrective measures. Where applicable, it also includes an economic assessment of the scope of the repair. The objective is to provide a solid technical basis to negotiate with the construction company, the promoter or the responsible parties involved in the work.

Coordination with lawyer

Legal aspects, such as the determination of responsibilities, the exercise of actions and legal deadlines, exceed the strictly expert scope. We recommend that you coordinate the report with a lawyer from the beginning, especially when a claim for LOE guarantees is raised.

For questions about claim deadlines, please also refer to the Legal issues section and the article on ten-year, three-year and annual warranty.
