Full Answer

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.
