3105-06 Concrete blocks, bricks, poles, piles, tiles and beams manufacturing

Applies to:

Businesses engaged in the manufacture of concrete blocks, bricks, poles, tiles, and beams.

This classification does not apply to the manufacture of these products when done by construction contractors for use in the construction project.

Work activities and processes include, but are not limited to:

• Receiving raw materials from others. Raw materials include sand, gravel, cement, cinders, aggregates, mesh wire, rods, and, in some cases, plastics.

• Mixing raw materials with water.

• Feeding the mixture of raw materials and water into molds or forming machines.

• Inserting heavy mesh wire or rods into the molds for strength.

• Steam drying the formed products.

• Placing dried products in the yard for curing.

• Shipping products.

Exclusions:

• Worker hours engaged in the production of raw materials are reported separately in the applicable mining, quarrying, or excavation classification;

• Worker hours engaged in installation or erection of products manufactured under this classification are reported separately in the classification applicable to the work being performed;

• Manufacturing concrete sewer and irrigation pipes, septic tanks, and concrete products not classified elsewhere is classified in 3105-07;

• Manufacturing statuary and ornamental items from plaster or concrete is classified in 3509;

• Manufacturing brick or clay products is classified in 3501.

Special note: This classification differs from classification 3509 "statuary or ornament manufacturing" in that products manufactured in classification 3105 are rough, do not require perfect finishes, and are generally for construction use; products manufactured in classification 3509 are for decorative purposes, are usually lighter weight, and have smoother or more perfect finishes than the concrete products manufactured in classification 3105.
