by There are several types of bridges and more are being developed every year. The types of bridge inspection included in the report below were developed by industry professionals. The information from these types of reports can save the insurance company millions and dollars that would be spent if a similar claim was later reviewed and found to be justified.
Types of Bridge Inspection The types of bridge inspections commonly utilized by insurance investigators include structural, hydrostatic, hydro-pump, structural stability, and material testing. All of these types of inspections must be performed in compliance with the regulations set forth by the Insurance Policyholder’s Benefit Program (IPBP). These types of bridge inspections may also be utilized to assist in the detection of problematic conditions that could develop into major problems later on.
What Does a Bridge Inspection Involve? A thorough examination is performed by an inspector in order to identify any potential dangers to the integrity of a structure or the location of a site. Typically, the inspector performs an inventory and a physical examination of the structure or location. This inventory is conducted both inside and outside of the structure. The inventory is used by the insurance provider as well as the inspector to determine the types of conditions that exist and which ones are most prevalent.
When performing this inspection, the inspector uses visual examination, testing, and access equipment to determine the condition of the location as well as the integrity of the infrastructure. This allows the inspector to pinpoint weak points and damaged areas. The inspector may also use visual and electronic means to detect problems and issues. The results of the inspections are often used as part of the basis for determining whether or not to deny or approve a structure or location for use. If conditions require additional attention due to deterioration or damage, these types of inspections become even more important.
Types of Bridge Inspections The main types of bridge inspections include Visualstatic, Volumetric, Asbestos, Hydrostatic, and Non-precast. Each type requires specific practices for the specific location. Most bridges are typically manufactured from either steel or concrete. However, there are some exceptions, including precast bridge foundations and certain pier foundations. In the event that a structure is susceptible to weathering, cracks, corrosion, or other damage, a visual inspection of the exterior and interior cannot verify these issues without further bridge inspection.
A bridge inspection is generally performed by a company that is licensed by the Department of Transportation (DOT) to perform such inspections. DOT does not license private inspectors, but many private inspectors are trained in the use of modern equipment, such as computer Aided design (CAD) software. To protect both the public and the individual who may be placing his or her life on the line by using this type of specialized equipment, DOT has established stringent regulations. Bridge inspections must be performed according to these guidelines to maintain both the integrity and safety of the infrastructure.
One of the most important components to a bridge inspection is the visual inspection of the steel and supporting equipment. This inspection must include a thorough examination of welds, fatigue, and any other signs of possible corrosion. The inspector should also check for gaps and openings in the foundation wall and surrounding structures. All of this information is used to determine whether further action is warranted and if the equipment, such as a crane, is safe to use.
Before a structure is deemed safe to use, the inspector performs an actual inspection. In this inspection, he or she uses a special camera equipped to detect flaws in the materials being used. If a visual inspection identifies material concerns, the inspector then recommends a specific course of action to correct the problem. There are two types of bridge rating; standard and maximum. For a structure to pass both tests, the engineer or architect needs to thoroughly discuss the situation with the customer.
