Commissioning is the process of planning, documenting, scheduling, testing, adjusting, verifying, and training, to provide a facility that operates as a fully functional system per the Owner’s Project Requirements. The goal of the Commissioning Process is to enhance the quality of the delivered project by focusing the design and construction team on the Owner’s goals for a functional and energy efficient building. The earlier a Commissioning Provider is involved in the project process the greater the chance there is for the Commissioning Provider to influence corrections without increased costs later.General engineering d.o.o. grew out of commissioning. Checking the most important parts of high and medium voltage plants and their commissioning through the commissioning process requires a broad knowledge of energetics as well as specialist knowledge in the field of protection. Gen.E engineers have tested and commissioned hundreds of plants in more than 50 countries.
