What is the nature of the construction industry?

The construction industry is divided into three major segments. Construction of buildings contractors, or general contractors, build residential, industrial, commercial, and other buildings. Heavy and civil engineering construction contractors build sewers, roads, highways, bridges, tunnels, and other projects.

What are the main principles of construction?

The Five Construction Principles have been established so that the five elements: environmental protection, safety, speed, economy, and aesthetics, conform with a balanced regular pentagon.

What are two characteristics of a project?

Project Characteristics: Key elements that Define a Project
  • Projects have a clear and distinct piece of work.
  • Every project is slightly different and unique.
  • Projects are temporary activities.
  • Projects have a final delivery at the end.
  • Projects have a clear objective.

What are the 5 types of construction?

Buildings can be categorized into five different types of construction: fire-resistive, non-combustible, ordinary, heavy timber, and wood-framed.

What are the five primary sectors of the construction industry?

2562 The five primary sectors of the construction industry are residential, commercial, heavy civil, industrial, and environmental construction.

What are the types of construction industry?

The four major types of construction include residential building, institutional and commercial building, specialized industrial construction, infrastructure and heavy construction.
  • Residential Building. …
  • Institutional and Commercial Building. …
  • Specialized Industrial Construction. …
  • Infrastructure and Heavy Construction.

What is Type 3 construction?

TYPE III – This type of constructed building is also called a brick-and-joist structure by some. It has masonry-bearing walls but the floors, structural framework, and roof are made of wood or other combustible material; for example, a concrete-block building with wood roof and floor trusses.

What is meant by type of construction?

What does “type of construction” mean? Within the National Construction Code (NCC) Volume One (Section C – Fire Resistance) the ‘type of construction’, generally determines how much a building is expected to be resistant to a fire (including all building elements – structural members and non-loadbearing components).

What are the classification of building?

1) Agricultural buildings 2) Commercial buildings 3) Residential buildings 4) Educational buildings 5) Government buildings 6) Industrial buildings 7) Military buildings 8) Religious buildings 9) Transport buildings 10) Power plants Classification of buildings  Based on occupancy  Based on type of construction. 4.

What is Type 6 construction?

6): Risk with this type of construction have structural floors and roof and their supports that are of material such as precast or poured- in-place reinforced construction.

What is Podium construction?

Podium construction – alternately known as platform or pedestal construction – is a building typology characterized by a horizontal division between a lower ‘podium’ and an upper tower. The podium, which is typically made of concrete or steel, is crowned by multiple light wood-frame stories.

What is the difference between 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.

What is Type 2 construction?

Type 2 construction is typically found in new buildings and remodels of commercial structures. The walls and roofs are constructed of non-combustible materials. Specifically, walls are usually reinforced masonry or tilt slab, while roofs have metal structural members and decking.

What are the ISO construction types?

ISO defines six construction classes for commercial buildings
  • Construction Class 1 — Frame.
  • Construction Class 2 — Joisted masonry.
  • Construction Class 3 — Noncombustible.
  • Construction Class 4 — Masonry noncombustible.
  • Construction Class 5 — Modified fire resistive.
  • Construction Class 6 — Fire resistive.

What is a Class 6 fire rating?

Class 6: Fire-Resistive

Exterior bearing walls should be made of noncombustible materials, but exterior nonbearing walls can be of combustible materials. Fire-Resistive buildings are usually high-rise office buildings, condos or parking garages. Their fire-resistance rating is two hours or more.

What is a Class 2 fire rating?

A Class II rating is given if the spread of flame is no greater than 215mm in the first 1½ minutes and on overall spread of no more than 455mm.

Which type of construction is called ordinary construction?

Ordinary construction consists of masonry exterior load-bearing walls that are of non combustible construction. Interior framing, floors, and roofs are made of wood or other combustible materials, whose bulk is less than that needed to qualify as heavy-timber construction.

What is Type 5b construction?

Type V construction is a fairly broad classification. It uses any structural element constructed from a material permitted by the code. Most wood-frame structures, including one- and two-family residences, fall in this category.

What type of fire is Class A?

Class A: Ordinary solid combustibles such as paper, wood, cloth and some plastics. Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.

What is a Class A fire retardant?

Class A fire retardants have a flame spread rating of between zero and 25. These materials are effective against severe fire exposure. Class B fire retardants have a flame spread rating of between 26 and 75. These materials are effective against moderate fire exposure.

What are the classes of fire ratings?

The scale is divided into three classes. The most commonly used flame-spread classifications are: Class I or A, with a 0-25 FSR; Class II or B with a 26-75 FSR; and Class III or C with a 76-200 FSR.

What are the 5 Classification of fire?

Fire is divided into five classes (A, B, C, D, and K) that are primarily based on the fuel that is burning. This classification system helps to assess hazards and determine the most effective type of extinguishing agent.

What types of materials fuel a Class A fire?

Class A: Usually the most common type of fire, as they are caused by combustible solid materials. This includes everyday materials such as paper, refuse, cardboard, wood, fabrics, and other flammable solid fuel sources.

What is an example of a Class A fire?

Class A fires involve ordinary combustible materials, such as cloth, wood, paper, rubber, and many plastics. Extinguishers with an A rating are designed to extinguish fires involving these ordinary combustible materials.

What are the 3 elements of fire?

Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
