Class Code: 6006F
Per NCCI's Scopes Code Description:
Code 6006F includes all pile driving and the construction of all jetties, breakwaters, seawalls, groynes (rigid structures built out from a shore to protect the shore from erosion), dikes, revetments, bulkheads, wharfs, docks, and piers, etc., performed around all bodies of water whether navigable or not. A jetty involves substantially more construction than either a dike or a levee in that it must extend into a body of water. A jetty will extend from the shore out into the water and will be constructed of heavy timber cribbing filled with boulders or heavy stones. Frequently, a jetty built of stones or boulders will be topped off with an asphalt surface or with concrete.
The construction of a dike as included in Code 6006F involves operations in which an embankment of earth is thrown against the edge of the river. The embankment is frequently paved with loose stone. In addition to the stones, the embankment may be anchored by lumber or willow mattresses, which are laid against the surface of the dike and held down by stone or piling. Another type of construction involves the building of crib work, which may be filled in with stone or other types of fill to keep the embankment in place.
Revetment work involves a facing or sheathing or woven mattresses of willow, lumber, etc., that are usually anchored to piles driven a few feet above the mean low water line and extended out into the river as the work progresses. Ballast stones are placed on the graded dike slope from the top down into the water’s edge. This type of work is performed in the water from work barges for pile drivers, derrick barges, mat and weaving barges, stone barges, etc.
Code 6006F includes the construction or repair of all wharfs, docks, and piers performed around all bodies of water, whether navigable or not. Code 6006F includes floating docks that are attached to these structures, while floating docks used in boatbuilding or repair are separately rated to the appropriate boatbuilding code.
