Class Code: 5057
Per NCCI's Scopes Code Description:
Code 5057 applies to employers that perform iron or steel work not otherwise classified in the manual. The classification is confined principally to groundwork where no structural operations are involved. It applies to raising supporting beams and trusses on walls of masonry or concrete construction where such beams do not constitute a part of the steel structure.
It includes setting up iron or steel tanks that rest on the ground, similar to those found on tank farms operated by the petroleum industry. It also includes the erection of cylindrical tanks not resting on steel supporting framework—the type common to industrial plants and fuel and oil dealers. Code 5057 also applies to iron or steel work in connection with the installation of lock gates, blast furnaces, windmills, outside railings, and coal chutes and the placement of iron or steel fronts as alterations to existing buildings.
Welding operations, whether performed by principal or specialist contractors, are considered incidental to the main iron or steel work and should be classified on the same basis as such work.
Code 5057 is also assigned to iron or steel work in connection with building raising or moving operations. When no separation of payroll exists, the payroll for the entire building raising or moving operation must be assigned to Code 5703 or the highest rated classification that applies, whichever is greater.
Extra-Territorial Classification Guidelines:
The following material was developed by NCCI to be used as a guide by auditors and underwriters in the determination of premium for contracting (construction employers) with extra-territorial employments where no company guidelines have been established for this purpose. Construction classifications are indicated by the addition of a construction code symbol ( • ) next to the classification code number.
When a portion of the operations of an employer is insured by a monopolistic state fund, consider the special rules and requirements that may exist in such cases.
Related Operations Not Classified to Code 5057:
Certain Code 5057 operations are designated as “not otherwise classified” (NOC). These NOC operations apply to an employer only when no other classification more specifically describes the employer’s operations. The following is a representative list of operations somewhat related in nature to Code 5057 operations that are not assigned to Code 5057.
|Fence Installation and Repair—Metal, Vinyl, Wood, or Prefabricated Concrete Panel Fence Installed by Hand
|Iron or Steel—Erection—Construction of Dwellings Not Over Two Stories in Height
|Iron or Steel—Erection—Frame Structures
|Iron or Steel—Erection—Frame Structures Not Over Two Stories in Height
|Sheet Metal Work—Installation & Drivers
In addition to this representative list, review sources such as the alphabetical index in this manual to determine whether a classification other than Code 5057 or a classification other than a classification on the above list applies to the operations being reviewed for classification purposes.
CROSS-REF. CONCRETE OR CEMENT—DISTRIBUTING TOWERS—INSTALLATION, REPAIR OR REMOVAL & DRIVERS
(N/A MA, TX)
|Erection, repair, or removal of concrete or cement distributing towers by contractors as an incidental part of their construction work shall be included in the classification with which the work is associated.
CROSS-REF. CONSTRUCTION—ELEVATOR OR HOD HOIST INSTALLATION, REPAIR, OR REMOVAL & DRIVERS—IRON OR STEEL BUILDINGS OR STRUCTURES
(N/A FL, MA, OR, TX)
The following operations will be classified as:
|Construction—Elevator or Hod Hoist Installation, Repair, or Removal & Drivers—Concrete or Concrete-Encased Buildings or Structures
|Construction—Elevator or Hod Hoist Installation, Repair, or Removal & Drivers—Iron or Steel Buildings or Structures
|Construction—Elevator or Hod Hoist Installation, Repair, or Removal & Drivers—Masonry Buildings or Structures
|Construction—Elevator or Hod Hoist Installation, Repair, or Removal & Drivers—Piers or Wharves
|Construction—Elevator or Hod Hoist Installation, Repair, or Removal & Drivers—Wooden Buildings or Structures Including Those Designed for Dwelling Occupancy
CROSS-REF. OIL RIG OR DERRICK ERECTING OR DISMANTLING—ALL OPERATIONS—METAL
(N/A MA, TX)
|Includes the construction of foundations or structures and the installation of equipment.
Code 5057 also applies to specialist contractors who set up iron or steel components in connection with oil rigs or derricks at their customers’ drilling sites. It also applies to specialist contractors who handle equipment such as cranes or conveyors including double rail or monorail traveling cranes at their customers’ industrial plants. The operations include incidental fabrication required to make the systems fit properly; bolting, welding or riveting and hoisting into position. The classification does not include the installation and service of the operating mechanisms such as belts, chains, sprockets, gears, or motors.
CROSS-REF. SCAFFOLDING—CONCRETE OR CEMENT DISTRIBUTING TOWERS INSTALLATION, REPAIR OR REMOVAL
(N/A AZ, MA, OR, TX)
CROSS-REF. SCAFFOLDING—SCAFFOLD INSTALLATION, REPAIR OR REMOVAL—BUILT UP FROM THE GROUND—NOT SUSPENDED OR SWINGING TYPE
(N/A MA, TX)
The following describes scaffolding operations and their proper classification assignments:
|Scaffolding—Concrete or Cement Distributing Towers—Installation, Repair or Removal
|Scaffolding—Delivery of Materials Only—No Installation, Repair or Removal—All Employees & Drivers
|Scaffolding—Outrigger Scaffold Installation, Repair or Removal & Drivers
|Scaffolding—Scaffold Installation, Repair or Removal—Built Up From the Ground—Not Suspended or Swinging Type
|Scaffolding—Sidewalk Bridges Not Over One Story in Height
|Scaffolding—Suspended or Swinging Scaffold Installation, Repair or Removal & Drivers
CROSS-REF. VAULT CONSTRUCTION OR INSTALLATION
|Applies to fire or burglarproof vaults.
Code 5057 applies to specialist contractors who construct or install fire- or burglar-proof vaults. Flat steel plates and angles—properly drilled and ready for assembly, and steel doors are received from others. Usually the reinforced concrete shell is constructed by others and separately classified. However, if these specialist contractors undertake the vault work from beginning to end (i.e., constructing the shell; lifting the wall and ceiling plates into place; securing by bolting, welding or riveting; mounting the doors; and installing the safe deposit boxes), the entire operations would fall within the scope of this classification.
CROSS-REF. WRECKING—BUILDING OR STRUCTURES—NOT MARINE—ALL OPERATIONS—IRON OR STEEL BUILDINGS OR STRUCTURES
(N/A FL, MA, TX, WI)
|Includes salespersons and clerical at wrecking site.
Code 5057 applies to the wrecking of iron or steel buildings or structures.
