The first [[hut (dwelling)|huts]] and shelters were constructed by hand or with simple tools. As [[cities]] grew during the [[Bronze Age]], a class of professional [[Artisan|craftsmen]], like [[bricklayer]]s and [[Carpentry|carpenters]], appeared. Occasionally, [[Slavery|slaves]] were used for construction work. In the [[Middle Ages]], the artisan craftsmen were organized into [[guild]]s. In the 19th century, steam-powered machinery appeared, and later, diesel- and electric-powered vehicles such as [[Crane (machine)|cranes]], [[excavator]]s and [[bulldozer]]s.

[[Fast-track construction]] has been increasingly popular in the 21st century. Some estimates suggest that 40% of construction projects are now fast-track construction.<ref>Knecht B.
