It has been difficult throughout the years to find material that lasts longer than marble, but at the same time is soft enough to be cut to size. For this reason, sculptors have used marble for busts and statues, most sculptures are made of marble.

Terrazzo was developed as a building material by the Venetians in the 1500s.
The diversity of jobs this creates lets skilled workers work on newly-build buildings and other re-modeled establishments. Generally materials are already prepared and ready for use in its operation. It takes only a few required skills on cuttings and polishing for the applicators to do the assignment. Picking up and carrying is generally done by helpers, as well as task of cement-mixing and mortar jobs. With the extra help the worker is able to do their work more efficiently to assure a superior outcome.
Title and terrazzo are used mainly on interior building surfaces, while marble is used primarily as exterior facing. Machine hoists aid in lifting large marble blocks. When setting- up the marble installation, there is a prior laying-out system that must be done by assigned workers. With the application of special plaster that backs the material strongly, the marble is set in its proper position. Piece by piece, the marble is placed firmly following a traced design for a more precise arrangement. A special grout is attached into various edges and joints between the pieces of the marble with a slightly indented pattern that forms a great work of art.
Terrazzo workers lay a base of fine, dry concrete, leveling this with a straight edge. They then place metal strips wherever there is to be a joint or where design or delineations are to be made. The metal stripping is embedded in the first course of concrete. Then the terrazzo workers pour the top course of concrete, a mortar containing marble or granite chips, and roll and level it. Different colored stone chips are used to color whatever pattern has been planned for the finished floor. In a few days, after the concrete has hardened the floor is ground smooth and polished.

The apprenticeship programs in each of these trades usually consist of hundreds of hours or a span of years for on the job training and related classroom instruction. During this time, the apprentices learn how to use the tools of their particular trade plus blueprint reading, layout work, basic mathematics, and shop practice. The booming construction industry creates thousands of diversity opportunities to the community. Young people still in school obtain work as laborers. The work includes mixing mortar, carrying, lifting, and cleanup work and other things that your crew members might need you to do.
