CON/SPAN® O-Series®

CON/SPAN® Bridge SystemsThe most optimized shape in the industry.

CON/SPAN’s innovative, economical design stands apart from any other system. Its distinctive arch action which utilizes fast, set-in-place construction, has been optimized, providing the ideal blend of hydraulic efficiency and structural capacity.

 

 

A legacy of innovative technologies blended into the optimized CON/SPAN O-Series

CON/SPAN Logo There are over 7,000 CON/SPAN B-Series installations since 1983. CON/SPAN Bridge Systems have been used by more state DOTs than any other system.

With a history of innovation and experience, Contech has taken precast buried bridge systems to the next level with the optimization of the CON/SPAN® O-Series™. Requiring less concrete per open area than any other precast buried bridge structure, the O-Series is the ideal blend of hydraulic efficiency and structural capacity. Spans range from 12’ to 65’.

 

Benefits of the CON/SPAN O-Series System:

  • Buried Bridge Structure - Reduces maintenance costs and lowers life cycle costs as there are no bridge deck or joints at the deck/roadway interface.
  • Modular Bridge System - Rapid installation results in reduced overall project costs, delays and detours.
  • Designed “Site Specific” - Meets your site needs in full compliance with AASHTO and AREMA design standards for highway and railway use.
  • Lighter piece weights or longer lay lenghts for most projects.
  • Outward horizontal reactions – one-sided keyway, reduced forming and grouting
  • Maximized clear span and clear distance between footings
  • PROVEN design methodology
  • Total reliabilty

Precast Bridges for Stream and Wetland Crossings

Precast Stream CrossingWhen environmental factors are a consideration, CON/SPAN O-Series and B-Series provide a natural choice because they offer clear spans from 12 to 65 feet with small footprints that minimize intrusion into natural areas. BEBO offers strength and stability, resulting in the largest precast arch spans available, allowing minimal impact to natural areas.

 


Precast Bridges for Pedestrian and Recreation Traffic Loads

Precast Bridge for Pedestrian CrossingCON/SPAN O-Series, B-Series and BEBO have been used in a variety of applications for pedestrian structures, including bike paths, ski tunnels under roadways, and golf courses. With an aesthetic appeal, these systems can provide access either over roadways or sensitive areas or under highways, even in high-fill applications.


Precast Structures for Bridge Rehabilitation

Precast Bridge RehabCON/SPAN O-Series, B-Series and BEBO bridge structures can cost-effectively and quickly be installed to support concrete bridges that exhibit deterioration in the concrete superstructure and upper portions of the abutments – utilizing the existing foundation. In most cases, in a single day, the bridge arches can be positioned leaving the existing beam bridge and abutments in place.


Precast Bridges for Bridge Replacement

Bridge ReplacementFor bridge replacement or Design Build projects, our Precast bridge systems can substantially reduce design and construction time, improve safety and ensure quality components for long-term performance.


Precast Bridges and Structures for Grade Separation

Precast Grade SeparationOur CON/SPAN and BEBO structures are commonly used for grade separations. These systems are strong enough to carry massive off-highway and railroad loads and are available in shapes to accommodate critical clearance boxes


Precast Bridges for Heavy Loading Applications

Precast Heavy LoadingCON/SPAN O-Series, B-Series and BEBO structures can easily accommodate Heavy Equipment Transport (HET) loading and maintenance requirements and set-in-place installation makes them a great solution for stream crossings.


Precast Structures for Mining Portals, Rail Tunnels and Conveyor Enclosures

Precast Rail TunnelOur durable CON/SPAN and BEBO structures can meet heavy duty demands for industrial or mining applications. CON/SPAN and BEBO structures can be adapted for use in tunnel applications or improving mine entrances. The arch shape is also ideal for supporting aggregate piles and can be designed to accommodate site specific openings and equipment requirements. Underpasses and overpasses can be designed using Cooper E-80 loading, and these prefabricated systems allow for fast installation and easily accommodate staged construction methods for busy, active railroad tracks.


Precast Structures for Culverts, Canals and Enclosures

Precast CulvertOur CON/SPAN O-Series, B-Series and BEBO structures provide a total set-in-place construction solution for culverts and stream enclosures.  

SS Credit 1 – Site Selection, 1 Point

Intent – Avoid the development of inappropriate sites and reduce the environmental impact from the location of a building.

Potential Contribution: Bridge and Structures

  • Long clear spans allow you to cross sensitive areas with little or no impact
  • Maintain a 50-foot buffer on either side of the waterway

SS Credit 2 – Development Density and Community Connectivity, 2-5 Points

Intent – Channel development to urban areas with existing infrastructure, protect greenfields and preserve habitat and natural resources.

Potential Contribution: Bridges and Structures
  • Connect people and services over roads, under rail crossings and across streams
  • Shorten walking distance to basic services
  • Provide aesthetic solutions

SS Credit 4.1 – Alternative Transportation, Public Transportation Access, 1-6 Points

Intent – Reduce pollution and land development impacts from automobile use.

Potential contribution: Bridges and Structures
  • Create bicycle trail connectivity - allowing alternative transportation mode
  • Create shorter, safer pedestrian access to public transit
  • Bring public transportation (i.e. railway) into a community with minimal impact to existing roads and grades

MR Credit 4 – Recycled Content, 1-2 Points

Intent – Increase the demand for building products that incorporate recycled content materials. The sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% (1 point) or 20% (2 points), based on cost, of the total value of the materials in the project.

Potential Contributions: Contech Concrete Structures
  • Many Contech vendors use recycled materials in their concrete mixes
  • Contact your local Contech representative for project specific information.
