Advances in technology over the past 25 years have drastically changed the construction industry. Construction had resisted many attempts to restructure it from a craft-oriented to a modular production line endeavor. Until recently, buildings and facilities were designed and built using methods similar to those used by the court of Louis XV for the furnishings at Versailles. Pieces were designed and constructed as unique items by a team of crafts people. Although this approach is still conceptually true in the building industry, repetition and automation at many levels of the construction process have been introduced to increase efficiency and improve quality and productivity.
