Bridges have marked their presence in human civilization since its beginning. Earlier, bridges were very simple and made up of timber or small draws or swings which were hand operated. These bridges had less of a life span than the modern bridges which are more complex and made with durable materials. Although, bridges are found in many forms, movable bridges are a unique type of bridge. Movable bridges are a type of bridge which can be opened to allow passage to any waterborne vessel like big ships. Some of the popular movable bridges are drawbridges, Iron trusses, Bascules, Vertical lifts. Types of movable bridge • Vertical lifts – the bridge deck is raised to allow passage to any vessel • Bascules – vehicular deck moved from horizontal position to vertical position or near to vertical position. • Swings – Bridge deck pivots in the horizontal position creating two channels for vessel passage The dynamic nature of the these bridges and their location near the water bodies make them vulnerable to rusting and other micro damages therefore periodic inspection is very important in their functioning properlyand preservation. Movable bridge inspection are conducted every two years and are of typically two types: Routine inspection and in – depth inspection. Routine inspection are currently more about visual inspection for any cracks or damages or mechanical lubrication and includes some trial openings. It also includes a cursory instrumentation check to be sure the bridge is functioning properly. In depth Movable Bridge Inspection are a detailed evaluation of the physical and mechanical condition of the movable bridge. Conventional movable bridge inspection involves intrusive and destructive methods to quantify and document the deterioration level. At Infrastructure Preservation Corporation (IPC), we provide the most advanced non destructive and non intrusive technology for thorough condition assessment during routine or in – depth movable bridge inspection. Our advanced but easy to use technology allows the bridge inspector and other staff to evaluate the condition of movable bridge with utmost safety and without disturbing the ongoing traffic on bridge deck. Our movable bridge inspection methods conform to FHWA & ASHTO requirements and uses non destructive technologies such as Laser scanning, Magnetic Flux Leakage testing, electromagnetics, Acoustic imaging, Aerial imaging, Ground Penetrating Radar, Ultrasonics and infrared testing to collect accurate data about internal cracks, damage, minor or major deterioration from inside of the infrastructure. Moreover, data collected during routine inspection helps in locating issues before they become a danger to the public. IPC’s structural health monitoring for moveable bridges also allow for IPC to monitor issues prior to them becoming a problem or the bridge getting stuck and the public being inconvenienced. Moveable brides and drawbridges can be easily monitored by IPC’s Drawbridge Structural Health Monitoring Service. This service allows basic service like hydraulics, electronic and fluids so that they can be fixed before a drawbridge gets stuck.
