A preliminary audit is required for an objective assessment of the current state of the facility before starting work. Over many years of work, we have come to the conclusion that with a 95% probability, after the start of work under the contract, nuances about which there was no information before and which can sometimes be of a critical nature will emerge. In this regard, after receiving all the information possible at a remote stage, we will definitely conduct our own audit for an internal assessment, which helps us to do our work efficiently and within the specified time.
