NEW BRIDGE DESIGN
INSPECTION & REHABILITATION
Corven Engineering works with Owners, Contractors, and other Engineers or as a part of a larger integrated team to produce complete concrete bridge designs. We design complex concrete post-tensioned and cable-stayed bridge bridges from foundations to superstructures. Contract Drawings and Specifications are developed in accordance with proven details and methodologies, kept current by knowledge gained from our other core work areas. Our experience includes delivering bridge designs in a variety of delivery formats including design-bid-build, design-build, and other innovative methods.
Understanding the condition of existing prestressed concrete bridges is key to controlling their safe operation. Corven Engineering has specialized experience in the condition evaluation of post-tensioning tendons. We often partner with local engineers with excellent traditional inspection resources to evaluate complex post-tensioned bridges.
Extending the useful life of existing bridges is an important component of meeting future transportation needs. Innovative post-tensioning solutions can enhance load carrying capacity and extend bridge life. Diligent analytical re-creation of as-built bridge conditions in accordance with original construction and condition changes over time helps us develop cost-effective rehabilitation solutions.
We also work with Contractors during construction to provide needed construction engineering services related to complex bridges. Typical construction engineering services for segmental bridges include time-dependent construction analyses, casting and erection manuals, precast segment geometry, and temporary works. Our CADD Technicians are highly experienced and provide the best in integrated shop drawings for precast segments.
Our team highly values opportunities to advance the technology of prestressed concrete bridges. We have worked with the Federal Highway Administration (FHWA) and State DOT’s to further design methodologies, construction details, specifications, and inspection procedures. Of special importance is our focus on increasing the durability of post-tensioned bridges.
The Engineers and Technicians at Corven Engineering have worked on the design and construction of significant cable-stayed bridges. This includes bridges with both concrete and steel superstructures. John Corven has participated in or directed the design of 9 cable-stayed bridges, 5 of which have been constructed. The nature of these bridges requires the complex analyses, specialized design, and proven detailing provided by our staff.
