WHY CON-STRUCT™?
Valmont® Structures Con-Struct™ Prefabricated Bridge Systems use proven materials, current design standards and new fabrication and construction techniques to reduce construction and maintenance cost, shorten construction time, increase quality and lengthen service life.
PROVEN PERFORMANCE
Cold-bent steel tub girders have been independently researched and tested by both Michigan State University and West Virginia University. Valmont Structures Con-Struct meets all AASHTO LRFD requirements and has been used and approved for both state D.O.T. and FHWA funded projects.
IBS FOR YOUR GRS
The Valmont Structures Con-Struct system is a perfect Innovative Bridge System (IBS) for your Geosynthetic Reinforced Soil (GRS) foundation. Our engineers ensure the elements are lightweight and can be built with concrete footings integral with the superstructure.
REDUCED COST
Because we partially assemble our system before shipping, our prefabricated bridges can be delivered and installed at less cost than that of conventionally constructed steel or concrete beam bridges.
FASTER CONSTRUCTION
Our superstructure can be erected and ready for traffic in a single day! Each unit is raised similar to that of precast concrete beams and designed for simple-span dead load and vehicular live load. Valmont Structures Con-Struct units are prefabricated with the final driving surface. Once placed, individual units can be secured together by a mechanical lateral steel connection or Ultra High Performance Concrete (UHPC) and opened to traffic.
REDUCED MAINTENANCE
The steel tub girder can be hot-dip galvanized, protecting the steel from corrosion and providing over 75 years of maintenance-free protection. That's not your average girder.
100 YEAR SERVICE LIFE
The concrete bridge deck is pre-compressed, further increasing the corrosion protection of the internal concrete reinforcement. Internal concrete reinforcement plus external galvanization and corrosion protection equals a service life we’re proud of, 100 years worth.
CONTROLLED CONSTURCTION
We eliminate field form, finish and curing by pre-casting the concrete deck. That deck is manufactured in a controlled casting environment, providing better quality and a more durable product for one of the most critical elements of the bridge.
SUPERIOR BRIDGE DECK
Our innovative fabrication process eliminates temperature and shrinkage cracks in the deck and provides superior protection of the underlying steel reinforcement. With Valmont Structures Con-Struct Prefabricated Bridge Systems, you can rest easy with a high-quality product.
