Structural Steel

Fabrication QA

Structural Steel

ON-SITE has maintained a strong position in the construction industry through its Quality Assurance inspection of both fabricated and erected structural steel as they relate to High-Rise, Single Story, Pre-Engineered Buildings, Sports Complexes, Exposition Centers, and Large Bridge Spans.

Special steel fabrications for Dams, such as large radial gates, fish screens, crane and hoisting equipment, penstocks are in our catalog of successfully completed inspection assignments.

ON-SITE routinely provides inspection during fabrication and erection of Structural Steel Bridges of varying type, size and complexity. Among the types of bridges we have provided Quality Assurance inspection includes Plate Girder, Box Girder, Truss, Pre-Stressed Concrete structures, Arch and Cable Stayed. Our staff is equally experienced in the inspection of Pilings, Bearings, Overhead Sign Structure’s, Lighting Standards, Guard Rails and Expansion joints.

To illustrate our contemporary experience with the provision of quality assurance services associated with the fabrication and erection of structural steel ON-SITE presents the following Project Profile capsules of current projects and previous project experience.
