Works and/or services carried out in situ (on the. Customer's site) always require prior preparation and/or logistical arrangements to be organised by the Supplier whether before and/or during the execution of the works, and which are not always based on quotations or perceptible by the Customer. However, depending on the time spent and costs incurred, the Supplier may charge for such work provided that this is agreed before its intervention, or on the basis of the costs incurred in that intervention.
