What is a Type 2 building?
Type II Construction: Non-Combustible Similar to the Type 1 buildings, Type 2 buildings contain non-combustible walls, partitions, columns, floors, and roofs. Though these structures typically contain fire suppression systems, they are not often protected with fire-resistive coatings and are prone to collapse.
What is Type II 222 construction?
Type II construction can be further classified as protected— Type II (222) or Type I (111)—in which the structural members have some degree of fire resistance, either 2 hour or 1 hour, or unprotected—Type II (000)—in which the structural members have no fire resistance rating.
How do you classify a building type?
Buildings can be categorized into five different types of construction: fire-resistive, non-combustible, ordinary, heavy timber, and wood-framed.
- Fire-resistive Type I (IA and IB)
- Non-combustible Type II (IIA and IIB)
- Ordinary Type III.
- Heavy Timber Type IV.
- Wood-Framed Type V.
What is Type 1 and Type 2 construction?
Type 1: Fire-resistive: High-rise buildings made of concrete and protected steel. Type 2: Non-combustible: Newer buildings with tilt slab or reinforced masonry walls and a metal roof. Type 3: Ordinary: New or old buildings with non-combustible walls but a wood-framed roof.
What are the 3 types of construction?
The construction industry consists of three sectors: buildings, infrastructure and industrial. Residential and non- residential are the two main types of building construction.

What is construction Type 442?
Type I (442 or 332) — “Shall be those types in which the fire walls, structural elements, walls, arches, floors, and roofs are of approved noncombustible or limited-combustible materials.”

What is Type 4 construction?
Type IV construction (Heavy Timber, HT) is that type of construction in which the exterior walls are of noncombustible materials and the interior building elements are of solid or laminated wood without concealed spaces.
Does CH2’s design approach address the formal precepts of appropriate architecture?
So, in addition to answering the technical issues, does CH2’s design approach address the formal precepts of being appropriate architecture, as opposed to merely being good building? For me, the answer is an overwhelming yes.
What are building occupancy classifications?
Building occupancy classifications refer to categorizing structures based on their usage and are primarily used for building and fire code enforcement. They are usually defined by model building codes, and vary, somewhat, among them.
What is the CH2 public face?
CH2’s public face is the tall facade overlooking Swanston Street, one of Melbourne’s great public boulevards. It is entirely composed of timber vertical slats covering a fully glazed wall. These slats pivot vertically, opening and closing in response to the time of day and the angle of the sun.
