Easily recognized by firefighters, these buildings feature wooden walls and roof spans seen on barns, factories and old churches. Roofs are especially at risk for quick fires and self-sustaining spread resulting from generated heat and vapors. What are the 4 types of construction? Type 4: Heavy timber type Most of the buildings constructed before 1960 were heavy timber-type buildings. Heavy timber buildings have structures built of wood but, given the large size of the timbers, they can withstand fires for longer than light wood frame houses. Heavy-timber structural members - columns, beams, arches, floors and roofs - are unprotected wood with large cross-sectional areas. Table 1: Type of construction required. This was a common practice before 1960, which makes heavy timber construction so easy to spot. New construction can be further divided into single-family homes, multi-family homes (apartments), and condominiums. Type IV - Heavy timber construction with moderate levels of fire-resistant construction Type IV A/B/C - Mass timber construction, allowing mid-rise and high-rise construction from wood products. This classification includes buildings that have floors, roofs, exterior walls, and frames made of slow-burning or noncombustible materials. Also known as "ordinary" construction; has brick or block walls with a wooden roof or floor assembly which is not protected against fire. TYPE V-A--Protected Wood Frame (Commonly used in the construction of newer apartment buildings; there is no exposed wood visible.) Outside and structural materials be made from non-combustible or minimally combustible materials. Type IV construction utilizes large dimensional lumber for structural members and interior elements.

Exterior Walls*. Mass timber elements shall meet the fire-resistance-rating requirements of this section based on either the fire-resistance rating of the noncombustible protection, the mass timber, or a combination of both . Thus, the required type of construction in this case would be Type C. For roofs and flooring, heavy planks with a minimum thickness of six inches are required. Structural Frame 1 Hr. It is a type of construction where the exterior walls are of noncombustible material and the interior building elements are of solid or laminated wood without concealed spaces. These structures are manly used in manufacturing centers, churches, and/or schools. Classification 3: Noncombustible. Buildings having masonry-bearing walls, but with wood or other flammable materials for the floors, structural framework, and roof, such as a concrete-block building with a wood roof and floor trusses, are examples of this type of structure.

Specialized Industrial Construction. Structural Frame 2 Hr. 3. Exterior Walls* No fire resistance for structural frame, floors, ceilings, or roofs. Examples of Artificial construction materials are bricks, cement, steel, glass, and plastics, etc. Examples of type 1 are high-rises and hospitals. Old churches, factories, and barns typically fall under this category. The timber members are either solid or laminated, and they must fit dimensional requirements. Floor/Ceiling/Roof TYPE V-B--Unprotected Wood Frame (Examples of Type V-N construction are single family homes and garages.

While the type of business using the building often dictates the layout, all office buildings require construction necessities like bathrooms and fire escapes. Interior structures are made of solid or laminated wood with NO CONCEALED SPACES. For fire retardant-treated wood permitted in roof construction and nonloadbearing walls where the required fireresistance rating is one hour or less, see 780 CMR 603.2 and 2310.0. TYPE IV: Heavy Timber (Also known as "mill" construction; to qualify all wooden members must have a minimum nominal dimension of 8 inches.)
