IV. Timeline and Payment

The timeline for implementing the project is an important factor that determines the success and reliability of the service. For the construction of the 160KVA – 22/0.4kV transformer station, the preparation and organization time for construction is 30 days. The specific construction time is as follows:

– Preparation Time: During this phase, tasks such as planning, designing, preparing materials, and organizing the site will be carried out. The expected time to complete these stages is 30 days.

– Construction Time: Once all materials are ready, the construction of the transformer station begins and is expected to last for 15 days. This includes the installation and connection of the necessary equipment for the station to operate.
