The four key types of construction include residential, commercial, industrial and infrastructure, which cover almost all construction projects. The last type of construction is infrastructure and heavy construction, which encompasses the construction and improvement of railways, communications and roads, railroads to the surroundings of a city, or the construction of existing buildings. The four main types of construction include residential buildings, institutional and commercial buildings, specialized industrial construction, infrastructure, and heavy construction. Some other projects included in this type of construction include tunnels, bridges, roads, transit systems, drainage systems, and pipelines.
With the Type II construction, firefighters may consider opening skylights or resorting to natural ventilation. If firefighters are called to a Type 2 building, their top priority will be to ventilate the building to avoid a dangerous increase in temperature. This list is called the 5 types of building construction, the first follows the most stringent fire resistance requirements and the fifth follows the minimum. Each of the 4 main types of construction comes with its own regulations and requirements, so each building or structure is compliant, safe and functional.
Newer school buildings, shopping malls and newly renovated commercial structures often belong to this type of construction. Depending on the roof system, they can also rely on similar ventilation operations for Type III and Type IV constructions. But those who work in it know that the industry is still very organized, divided into specific types of construction and processes. The fire rating assigned to wood and other materials associated with Type IV and Type V construction often varies by thickness.
That said, many Type III buildings contain connected attics or horizontal empty spaces, making it more likely that a fire will spread. Type V construction requires other alternatives, including, but not limited to, positive pressure attacks. Each type of building construction is associated with different construction elements, each of which varies in terms of fire resistance. Type A refers to “protected buildings”, while type B exists in reference to “unprotected buildings”.
Type IV buildings are largely constructed of large pieces of wood, connected by metal plates and bolts.
