Transmission & Distribution Engineering
Structural engineering, design and detailing for the steel poles, lattice towers, and line systems that carry critical power.
SANPEC brings transmission-line engineering and a sustainability-minded approach to steel structures, line design, structural optimization, reinforcement, and foundation work. The work is organized around reliability, constructability, lifecycle value, and the requirements of real transmission programs.
Why it matters
Built around the source-site commitment to reliable and resiliency-based design for transmission structures.

Define the line condition
Clarify the structure, corridor, loading, component, lifecycle, and delivery requirement.
-
Engineer the system
Apply structural analysis, design, detailing, reinforcement, and foundation considerations.
-
Validate the decision
Connect the work to testing, specifications, inspection, and material evidence where relevant.
-
