Class Code: 6252

Per NCCI's Scopes Code Description:

Code 6252 is applied to specialist contractors engaged in all operations involving shaft sinking for bridge footings, piers or foundations. The operations involve the removal of earth from a hole with a relatively small diameter and usually from a considerable depth as compared with its diameter. To prevent cave-ins, wooden or steel sheeting may be driven into the shaft by hand or power apparatus. The classification contemplates these operations as well as any pile driving and concrete work connected herewith. Code 6252 also is applied to specialist contractors engaged in all operations involving pneumatic caisson work for bridge or pier foundations.

Pneumatic caissons are closed casings in which air pressure is maintained equal to the pressures of water or soil on the outside. The classification includes all employees working under air pressure, others engaged in or upon the caisson or the apparatus connected therewith as well as any pile driving, excavation, masonry or concrete work.

This classification also is applied to specialist contractors engaged in all operations involving non-pneumatic caisson work for bridge abutment, pier and underwater foundation construction up to the completion of the subbase or sub-foundation. The classification contemplates the driving of steel piling to the desired depth to form compartments of the required size and the removal of earth and water by clamshells or pumps. It also contemplates the pouring of concrete into the shell and the removal of the piling. Non-pneumatic caisson work in connection with dam or lock construction falls within the scope of this classification but only with respect to the construction, maintenance or removal of the caisson. Code 6252 additionally is applied to specialist contractors engaged in all operations involved in non-pneumatic cofferdam work. The cofferdam is a temporary structure to provide a dry work area for building bridge piers and foundations for dams, locks and other structures. The classification includes pile driving, excavation, masonry or concrete work up to the completion of the subbase or sub-foundation and the removal of the cofferdam. Non-pneumatic cofferdam work in connection with dam or lock construction applies only to the construction, maintenance or removal of the cofferdam.

Please refer to Code 5403 for extra-territorial premium determination guidelines that may be applicable to insureds that have operations outside their headquarters’ state.

State Addendum
Massachusetts Code 6252 is applied to all qualifying operations, regardless of whether or not the work completed is non-pneumatic.
