As a developer, you are ultimately responsible if the contractor fails to comply with the rules of the game to use certified products, as you are the developer who will hand over the proper documentation and certificate at the end of the survey to obtain final proof from the building board and thus gain access to the building.
Although there are developers who will argue that "it is the contractor's responsibility to resolve the situation if it turns out that the product is incorrectly documented", we certainly believe that you as a developer will not be particularly happy if it turns out that your tenants cannot move in to their homes, or that the companies that were going to open their business in the shopping centre cannot do so, because the entrepreneur, the developer used products that are not certified and thus need to be replaced before access can be granted. As a builder and manager of the construction site, you are ultimately responsible for the building's fire protection, and in the long run the operator who will have to deal with maintenance costs.
Choosing wood panels with incorrect documentation can be very expensive, and choosing wood panels treated regardless of method (impregnation/paint) without durable properties is a very poor investment and complete waste of money.
