Current through Register Vol. 24-14, July 15, 2024
0201-01 Bridge, trestle, overhead crossing and viaduct:
				Construction, maintenance and repair
Applies to contractors engaged in the construction, maintenance
				or repair of bridges, trestles, overhead crossings and viaducts including the
				foundations and approaches. These types of structures provide a series of spans
				or arches, or a type of vertical and horizontal framework for a road or
				railroad passage over an obstacle such as a waterway, wide valley, other roads,
				or railroads. Work contemplated by this classification includes the
				construction of approaches, abutments, foundation supports, framework, and
				includes all concrete, iron or steel, timber, or carpentry work to completion
				of the project. The approach is the area of ground or roadway built up just
				before entering onto a structure such as a bridge or trestle. The abutments are
				the reinforced foundation supports at the end of the approach which will bear
				much of the weight for the structure. The erection of the structure usually
				begins at both ends of the approaches and abutments and gradually continues
				toward the center of the structure. This classification includes activities
				such as, but not limited to, the placement and securing of piles, beams and
				members by way of boom or crane, forming columns, piers and supports, tying
				reinforcing steel, set-up and tear down of forms, pouring and finishing of
				concrete, installing precast deck supports, decking slabs and nonstructural
				members, constructing the retaining walls, erecting iron railings, and the
				installation of suspension cables and cable clamps. This classification also
				includes shaft sinking, pile driving, caisson and cofferdam work as it is
				considered an integral part of the structure's foundation and support.
This classification excludes asphalt surfacing/resurfacing on
				roadways which is to be reported separately in classification 0210 and concrete
				paving which is to be reported separately in classification 0214.
Special note
:
Care
				should be exercised prior to assignment of this classification as the workers
				could be subject to federal laws covered by the Jones Act or by the U.S.
				Longshore and Harbor Workers Act. A detailed description of these acts can be
				found in classifications 0104 or 0202.
0201-04 Breakwater, jetty, levee: Construction,
				maintenance and repair
Applies to contractors engaged in the construction, maintenance
				or repair of a jetty, levee or breakwater. These types of barriers or
				embankments are very similar to a dike, but involve substantially more
				construction in that they usually begin away from the water and extend into a
				body of water and are sometimes used as protection for a harbor to prevent
				adverse currents from interfering with shipping. Work contemplated by this
				classification involves building, protecting and/or filling in an embankment or
				barrier of a river, harbor or other body of water. The predominant activity
				involves earth moving or placing of fill or other material. This classification
				includes, but is not limited to, clearing of land, excavation, filling, and
				grading and involves earth moving equipment such as, but not limited to, drag
				lines, graders, scrapers, bulldozers, and dump trucks. Materials include, but
				are not limited to, dirt, sand, stones or boulders, concrete piles, timber or
				heavy timber cribbing filled with stones or boulders. Often, the barrier or
				embankment being built is seeded or paved in part with asphalt, concrete, soil,
				or cement to assist in strengthening the structure.
This classification excludes pile driving operations in
				connection with jetty, levee and breakwater operations which are to be reported
				separately in classification 0202, and asphalt surfacing/resurfacing which is
				to be reported separately in the classification applicable to the work being
				performed.
Special note
:
Care should be
				exercised prior to assignment of this classification as the workers could be
				subject to federal laws covered by the Jones Act or by the U.S. Longshore and
				Harbor Workers Act. A detailed description of these acts can be found in
				classifications 0104 or 0202.
0201-05 Bulkhead retaining walls: Construction,
				maintenance and repair, riprapping - All water hazard
Applies to contractors engaged in the construction, maintenance
				or repair of a bulkhead. A bulkhead is a wall or embankment constructed to
				protect against potential problems such as earth slides, erosion of banks
				alongside water, or excessive increases in the water level. Work contemplated
				by this classification involves building, protecting and/or filling in a wall
				or embankment of a river, harbor or other body of water, or other areas of
				land. The predominant activity involves earth moving or placing of fill or
				other material. This classification includes, but is not limited to, clearing
				of land, excavation, filling, and grading. Equipment used by contractors
				subject to this classification includes, but is not limited to, drag lines,
				graders, scrapers, bulldozers, and dump trucks. Materials include, but are not
				limited to, dirt, sand, stones, boulders, concrete piles, timber or heavy
				timber cribbing filled with stones or boulders. Often, the wall or embankment
				being built, or if it already exists, is seeded or paved in part with asphalt,
				concrete, cement, or soil to assist in strengthening the structure. This
				classification includes riprap work which is a loose assemblage of broken
				stones erected in water or on soft ground. Such stone serves as a fill-in
				material to assist with the building of a dike, levee, or bulkhead.
This classification excludes pile driving operations in
				connection with bulkhead construction operations which is to be reported
				separately in classification 0202, and asphalt surfacing/resurfacing which is
				to be reported separately in the classification applicable to the work being
				performed.
Special note
:
Care should be
				exercised prior to assignment of this classification as the workers could be
				subject to federal laws covered by the Jones Act or by the U.S. Longshore and
				Harbor Workers Act. A detailed description of these acts can be found in
				classifications 0104 or 0202.
0201-06 Concrete culverts; aluminum, steel, or other
				types of culverts over 12 feet
Applies to contractors engaged in the construction or placement
				of concrete culverts or other types of culverts greater than twelve feet in
				diameter. A culvert is a sewer or drain running under a road, embankment, or
				structure such as a bridge. Culverts can be made of material such as, but not
				limited to, concrete, aluminum, and galvanized steel. Their primary purpose is
				to channel excess water away from the road, embankment, or structure to assist
				in preventing water damage or flooding. Work contemplated by this
				classification includes excavation, laying of sand or gravel, placement of
				culverts, and filling in the site.
0201-08 Tunnels and approaches
Applies to contractors engaged in the construction of tunnels
				and approaches including the lining, cofferdam work, shaft sinking, and well
				digging with caissons. A tunnel is a passage through or under a barrier to be
				used as a roadway, railway or pedestrian walkway. The approach is the area of
				ground built up before the entrance of a tunnel or similar type of structure.
				Work contemplated by this classification includes, but is not limited to, the
				construction of approaches, shaft sinking, caisson and cofferdam work, boring,
				the framework or lining, and all concrete, iron or steel, timber, and carpentry
				work to completion of the project. In some instances, the initial phase of a
				tunnel project may require that the approaches and abutments be put in place.
				This may involve extensive excavation and fill work depending on how uneven the
				terrain is with the proposed tunnel entrances. The abutments are the reinforced
				foundation supports at the end of the approach and will bear much of the weight
				at the tunnel entrances. Most often, the abutments will consist of metal beams
				or concrete with reinforced steel, that are placed vertically, horizontally or
				at an angle into the ground. The boring of the tunnel may include the removal
				of earth, rock and water with mechanical equipment, drilling and boring
				machines, rock drills and chippers, explosives, well drilling with caissons,
				and the need for pumps and drains piped to the outside of the bore.
				Occasionally, a cofferdam is erected which is a temporary structure from which
				water can be pumped or sucked to provide a dry work area during construction of
				the structure. Once the structural support is complete, the cofferdam is taken
				apart and removed. As the bore progresses steel I-beams are placed and
				horizontal beams or solid bar stock are bolted or welded for support. Shielding
				the bore between the I-beams requires bolting or welding steel plates to the
				beams. This is followed by filling the gaps between the face of the bore and
				the shielding with sand or concrete grout. Some tunnels will then be lined with
				concrete, steel or tile, and lighting, ventilation and drains may be
				installed.
This classification excludes underground mining operations
				which are to be reported separately in classification 1702, and asphalt
				surfacing/resurfacing or concrete paving which is to be reported separately in
				the classification applicable to the work being performed.
0201-09 Diking, N.O.C.
Applies to contractors engaged in the construction of dikes not
				covered by another classification (N.O.C.). A dike is a type of protective
				barrier or embankment which keeps a body of water such as a river in its proper
				channel and prevents the erosion of banks. Work contemplated by this
				classification involves building up and/or protecting the embankment. This
				classification includes, but is not limited to, earth moving work, assemblage
				of loose stone or rock, placement of sandbags or concrete piles, fill dirt or
				broken pieces of concrete, or building of crib work which may be filled in with
				stone or other types of fill. This classification also applies to diking or
				ditching work in connection with oil spill clean-up such as alongside a river
				bank or other shoreline.
This classification excludes pile driving operations which are
				to be reported separately in classification 0202.
Special note
:
Care should be
				exercised prior to assignment of this classification as the workers could be
				subject to federal laws covered by the Jones Act or by the U.S. Longshore and
				Harbor Workers Act. A detailed description of these acts can be found in
				classifications 0104 or 0202.
