Construction Leadership by the Contractor with Documentation Support from the Investor

In the development of the transformer station, the contractor is tasked with overseeing all facets of the project, demonstrating expertise in compliance with electrical regulations and collaborative efforts with energy authorities. The investor simplifies their participation by supplying essential legal documentation, including land ownership certificates, necessary permits, and valid identification, each notarized and up-to-date. From the initial stages through to the finalization of the project, the contractor is dedicated to managing design, grid connection, and execution, all within a strategically scheduled 60-day timeline. This includes 45 days dedicated to preparation and 15 days of intensive construction

Financial Stages in Building a Transformer Station: Coordination Between Contractor and Investor

The payment structure for constructing a transformer station is divided into three distinct phases. The first payment occurs right after the contract is signed, providing the contractor with the funds necessary to begin the procurement and delivery of materials and equipment to the site. The second payment is made when the contractor notifies the investor of the delivery of the transformer, which then proceeds with its installation and initial operational steps. The final stage of the financial agreement culminates with the last payment, which is made once the transformer station is fully energized and all testing, undertaken jointly by the contractor and investor, has been successfully completed.

Client Support and Warranty Guarantee

After construction is completed, clients benefit from a one-year warranty, which reinforces the dependability of the project and bolsters their trust in its operational functionality.
