The criteria for bridge inspection include elements that define the safety and load capacity of the bridge, elements that define secondary bridge components and other elements created by independent bridge construction agencies. Examples of minimum elements that define safety and load capacity include construction of decks, girders, abutments, slabs and columns. The main secondary bridge components are protective coatings and paintings.Continue Reading
Licensed bridge inspectors consider the safety of the bridge by measuring its ability to sustain expected weights. The load capacity of the bridge dictates the maximum weight of vehicles allowed to use it. Inspectors check the way a construction company structures its decks, girders, slabs, abutments and columns. The load capacity determines the type of material used for construction of bridges.
Most local authorities and bridge inspection companies have their preferred materials to be used by construction companies. There are specific levels required for bridge coatings. Coatings are important because they reduce the amount of moisture infiltration into the bridge structure. Bridge construction companies also include their own elements of construction in addition to the ones specified by inspection bodies. Bridge inspection manuals allow such inclusions to enhance flexibility for the bridge owners. Changes can be made depending on the owner's preferences. However, any element included by the bridge owner must be in line with the bridge construction regulations.Learn more about Branches of Government
