Surveying during bridge construction has many facets requiring professional judgment and expertise. For form work, offset lines are more important than basic center lines. Edges of girders must meet abutments and piers. Settlement and deflection of falsework and permanent camber must be figured into elevations. Close control must be exercised during the entire construction of a bridge. Permanent reference points are important in case the bridge suffers settlement or earthquake.
