What Langston builds as a utility contractor
Underground utility construction is one part of a broader utility scope. As a utility contractor, we build the civil, structural, and security work across substation, water, data center, and transportation sites.
Site and underground utilities
Water, sewer, storm drainage, and site utility trenching, built as part of the civil package on utility and industrial sites.
Substation civil and foundations
Pads, foundations, control-building shells, and yard site work. The electrical scope stays with the utility and its contractor.
Water and wastewater structures
Treatment structures, tanks, and pump-station work for water and wastewater utilities.
Structural concrete and steel
Cast-in-place concrete and structural steel to ACI 318, AISC 360, and AWS D1.1.
Physical security and NERC CIP-014
Perimeter fencing, walls, gates, and CIP-014 hardening for substations and critical-infrastructure sites.
One utility contractor, start to finish
A single prime contract from site and foundations through structures and physical security.
Why utilities choose Langston
