Industry Changes


New building products and techniques are continually being developed for the construction trades. Those who do framing and install walls and ceilings have benefited from research and development that have produced simplified ceiling, wall and floor installations. Drywall sheets have become larger but lighter and are easier to handle. The use of exterior studs has also made work less labor intensive. The introduction of lasers to the trade, including laser alignment systems has increased the efficiency and accuracy of layout lines. These new materials and techniques have given businesses more quality control of workmanship. Building codes have also been updated to reflect these improvements in products and techniques.

Over the next ten years, the employment outlook is considered to be excellent. The lack of trained and qualified Drywall and Lather technicians and the expected increased retirement rate in these trades over the next decade highlight the opportunities within the industry for good potential jobs. Demand should also be high for those who stay informed about new developments in this field.
