Overview
The construction of large bridges and related infrastructure, often in crowded urban or sensitive areas, demands specialized construction systems and expertise. STRUCTURAL TECHNOLOGIES / VSL, along with our global network of equipment, gantries, and engineering support, is dedicated to developing unique solutions tailored to your project’s requirements.
No matter the complexity or challenges of a project, STRUCTURAL TECHNOLOGIES / VSL has a proven track record of delivering customized engineered solutions. We specialize in lifting, lowering, and sliding precast segments precisely into place or constructing massive cast-in- place cantilevers.
STRUCTURAL TECHNOLOGIES is the exclusive manufacturer of VSL post-tensioning products and construction systems in the United States. Our manufacturing facilities in the United States are certified by PTI’s Plant Certification Program to ensure the highest quality fabrication of materials.
Engineered Solutions for Cast-in-Place or Precast Bridge Construction
No matter how complex or demanding a project may be, STRUCTURAL TECHNOLOGIES / VSL offers a long history of customized engineered solutions to lift, lower, and slide precast segments to precise locations or to construct massive cast-in-place cantilevers.
Improve Quality, Efficiency and Safety
Our team works with you to develop project-specific construction methods that promote highly efficient rates of construction, while constantly improving the safety and quality control measures to meet ever-changing job requirements.
Single Source Provider
Our line of post-tensioning systems – including specialty and heavy lifting equipment, engineering services, and technical support for installation provide a single-source solution for your project.
Modular Form Travelers
Designed for balanced cantilever concrete brides, STRUCTURAL TECHNOLOGIES / VSL’s form traveler system is an economical and efficient construction method. It incorporates a robust framework that minimizes deflections during concrete placement. We engineer these highly adaptable systems for a variety of segment lengths, depths and structure.
Precast Segmental Construction Methods
STRUCTURAL TECHNOLOGIES has extensive experience erecting various types of precast bridge structures. Our capabilities include utilizing launching girders, beam launchers, and lifting frames capable of positioning precast beams behind, below, or in parallel to the erection system.
Methods utilized for precast segmental construction include:
Balanced Cantilever Erection
with Launching Gantries
Span by Span Erection
with Launching Gantries
Precast Beam
Method
Full Span
Precast Method
Incremental Launching Method
For straight or continuously curved bridges, STRUCTURAL TECHNOLOGIES employs an efficient incremental launching method to reduce construction costs and accelerate project timelines. Segments are cast in a dedicated casting bed at the bridge abutment, connected sequentially, and launched using VSL hydraulic jacks. We provide comprehensive equipment, engineering, reinforcing materials and experienced crews for this innovative approach.
