Bridges are usually built to provide people with a convenient method to commute and cross an obstacle like a river or a chasm or any structure artificial or natural. As traffic increases and thereby increasing the load a bridge will need to be assessed and periodically inspected so to make minor repairs and allow the department of transportation to allocate assets to keep our bridges in top shape. |
Nowadays, bridges are a magnificent work of engineering and a representative of a country’s advancements in the field of architecture. In fact, people know many countries due to their marvelous bridges. Built to bear burden and open commerce routes and help a country build their economy, what if one of these bridges collapse or fail to serve their purpose? The answer is simple – when bridges fail in their purpose, they pose a serious risk to life and to a nation’s economy. People are late to work, goods are late to market, exports slow and an economy can be brought to its knees if enough of its infrastructure fails.
This is one reason why Bridge Inspections are taken so seriously by countries all over the world. Although the US has been slow to adopt new methods many countries now employ modern technology and robotics to inspect their infrastructure. Using highly advanced nondestructive testing methods, bridge inspectors analyze the structural and functional aspects of bridges. Structurally deficient and functionally obsolete bridges are closed noticed to limit their load for public use until they are restored and tested as being safe for the expected traffic load.
Functional aspects of bridges are determined by its geometry and layout, which must meet current highway design trends to meet modern traffic requirements. It must be designed with future area growth and weather conditions in mind.
A number of tests are performed to determine the structural integrity of bridges. A negative test triggers a concern and the passage is declared not fit public use. Negative test results can appear due to various reasons:
• A bridge stuck by a vehicle
• In case of fire and natural calamities like excessive rain, flood, etc.
• Prolonged use resulting in the deterioration of structural components of a bridge
• Use of poor grade material and components
A bridge inspector relies on the technological innovations to assess and evaluate a bridge, as well as prepares a report on the structural and safety components of the bridge. In case the deterioration has reached dangerous levels, immediate repair is suggested and the passage may be closed for use to perform the necessary repair.
Bridge inspection companies like IPC – Infrastructure Preservation Corporation – can perform complex bridge inspections using nondestructive methods to produce a detailed conditional assessment report. Their work is of great help in evaluating current infrastructure utilizing modern technology and robotics as well as preventing further deterioration by taking appropriate steps in response to a damage report. Bridge inspection services by IPC are characterized by their patented robotic nondestructive assessments of our infrastructure.
