BLD has conducted numerous projects consisting of the construction and/or reconstruction of various roadways as well as extensive associated drainage improvements. These projects often consist of reinforced concrete as well as asphalt-concrete pavements in addition to curbs, gutters, sidewalks, driveways and other surface features. Associated drainage improvements involving widening and extensions of open drainage canals and ditches, as well as various improvements for subsurface drainage pipes and catch basins, such as installation of new pipes and relocation of existing pipes, are also commonly done.
