The Emerging Infrastructure Crisis MITIGATING THE EMERGING INFRASTRUCTURE CRISIS As you know, building and maintaining bridges today requires dealing with unprecedented challenges: • Population growth Higher traffic loads Corrosive pollution Aging infrastructure Hightlighted by the recent Morandi Bridge collapse in Genoa, an increasing list of global bridge ‘health problems’ threaten public safety. In short, public infrastructure investments have not kept pace with advances in architecture, scientific engineering, data communications, and urbanization. We’re helping change that. “At our...

Aging infrastructure Emerging Trends for Bridge Durability MAIN ISSUE: AGING INFRASTRUCTURE Although the bridges of the ‘60s and ‘70s were built to last 100 years, the reality of wear and tear means that bridges need a lot more care in the last 30 years of their life. We need cost-effective ways to lower: • Risks to assets and public safety Maintenance expenditures Repair and strengthening costs It’s Time to Fix America’s Aging Bridges Out of the 614,000 US bridges circa 40% are more than 50 years old and almost 10% need significant maintenance or replacement. On average, 188 million...

A New Bridge-Lifespan Approach Data-backed services specific to the age, size, and requirements of your bridge. DYWIDAG has been engineering bridge technology since 1880. Microsoft has been processing data since 1975. Together we’re researching ways to improve infrastructure through smart city technology. Safer bridges through inspections and technology A safe bridge is always under surveillance. Using robotic inspections of stay cables and advanced monitoring schemes for the entire bridge structure, we track and model structural and environmental phenomena. The demand on infrastructure is...

Advanced-life phase AN APPROACH DESIGNED FOR EACH LIFE PHASE ADVANCED LIFE PHASE: 10 YEAR SERVICE EXAMPLE From the first monitoring system, to the challenges of aging infrastructure, we support you through all phases of the bridge lifespan. New-life phase Early-life phase Tracking the bridge’s status from it’s very first sensor pulse. Early-life bridges need to settle into their environment. We learn how your bridge behaves (compared to its intended design) and identify any lingering issues or needed modifications. We study your bridge’s interaction and behaviour through regular inspections...
