TRANSMISSION SERVICES

Transmission Engineering design requires innovation and creativity. Our team of experienced engineers and designers have expertise in overhead and underground transmission projects with voltages ranging from 34.5kV-345kV.

​

At Tier 1 we offer a complete range of Transmission engineering and design services for all aspects of line extensions, rebuilds, and major transmission additions to deliver the highest quality products at reasonable costs to our valued clients.

​

We strive to support all phases of a project cycle from conceptual design studies through final engineering, design and project management services, providing recommendations for transmission lines and related equipment best suited to the development of the transmission system, consistent with economic balance, investment efficiency, and reliability criteria.
