Construction site and equipment prepared for start of work in Cologne, Germany (2017) Construction is a general term meaning the art and science to form objects, systems, or organizations, and comes from Latin constructio (from com- “together” and struere “to pile up”) and Old French construction, To construct is the verb : the act of building, and the noun is construction: how something is built, the nature of its structure.
- In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure, industrial facilities and associated activities through to the end of their life.
- It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning,
The construction industry contributes significantly to many countries’ gross domestic products (GDP). Global expenditure on construction activities was about $4 trillion in 2012. Today, expenditure on the construction industry exceeds $11 trillion a year, equivalent to about 13 percent of global GDP,

How would you describe the construction industry?
Abstract – Construction industry refers to the industrial branch of manufacturing and trade related to building, repairing, renovating, and maintaining infrastructures. It is a determinant of the country’s technological and technical advancement, often regulating the growth of the country’s infrastructural development that often directs to the country’s advancement in terms of sustainability assurance.
Unfortunately, the construction industry is one of the largest waste generating industries currently. This chapter explores some of the commonly produced waste in the construction industries along with their corresponding construction sources and hazards. And it also suggests approaches to ensure source-level minimization of such waste produced by construction industries.

What is a construction life cycle?
Phases of construction project management – As mentioned earlier in this piece, the five critical elements of a construction project management lifecycle are initiation, planning, implementation, performance and monitoring, and closing. Project owners and delivery teams looking to deliver full visibility, schedule control, risk reduction, and workforce collaboration are increasingly harnessing the power of construction project management software to achieve this, Efficiency, document management, and on-site management are just three construction components that can be implemented and monitored with high-performance software such as Oracle Aconex,
- When assessing both the value chain and the impact on the construction project management phases, this software can streamline and support project progress.
- After the initiation of the project, planning becomes a critical phase.
- When it comes to the value of integrated project management software, planning cannot be overstated as it allows divisions, management and stakeholders to stay connected and highlight any potential problems pre-launch.
With software such as the industry-leading Oracle platform, recording data during planning becomes simpler and can remain accurate in real-time. It is a case of the whole team being able to, quite literally, stay on the same page at every juncture of the project with schematic documentation.
- Another one of the construction project management phases, performance and monitoring, can be significantly improved and impacted by project management software.
- Measuring progress with software, in real-time, is not only effective in terms of cost but it also allows risk mitigation to be ongoing through construction reports that can be automatically generated.
This can be done with the frequency determined by the project manager, allowing the software to generate reporting documents available to all stakeholders, One of the main benefits of construction project management software comes at the closing phase of the construction lifecycle.
What is the main purpose of the construction industry?
The Construction industry is focused on the construction, demolition, renovation, maintenance or repair of building and infrastructure. It covers a wide range of services, from planning and surveying to structural construction to finishing services such as painting and decorating.
What is the main aim of the construction industry?
Why is construction important? – Construction is a vital industry, creating buildings and spaces that connect communities, providing jobs, and improving society.
What is the most important factor in the construction industry?
The ability to manage the business efficiently is the most important factor, particularly to deal with tightening competition. The ability to reduce costs and optimize efficiency are highly incorporated in the rating consideration.

What is type B in construction?
Standards and codes have been developed to ensure that all constructed objects such as buildings and furniture, conform to a minimum level of safety. The codes are designed to protect public health, safety, and general welfare as they relate to the construction and occupancy of buildings and structures.
The building code requires all building work comply with the code. Many of the specific standards and codes within Australia are controlled by the Australian Building Codes Board (ABCB), and the details and copies of the standards are available at the ABCB website, BCA building classes The BCA classifies buildings by their use.
A building may be made up of a number of classes if it has a mixed use. The BCA identifies the following building classes: Class 1a – a single dwelling or attached dwellings (eg a terrace, duplex, etc) where each dwelling is separated by a fire wall. Class 1b – one or more buildings that constitute a boarding house, guest house, hostel of small scale (ie not exceeding 12 persons or 300m2 in floor area).
- Class 2 – a building containing two or more dwelling units (eg flats, apartments).
- Class 3 – a residential building for a number of persons such as a large scale boarding house, guest house, hostel, the residential part of a hotel, motel, school, etc.
- Class 4 – a dwelling unit that is a part of a commercial use (eg a caretakers/managers flat).
Class 5 – an office building. Class 6 – a shop or other building where goods or services are retailed directly to the public. Class 7a – a car park building. Class 7b – a storage building or building where goods are wholesaled (eg a warehouse). Class 8 – a laboratory or a building where a process takes place (eg factory, workshop, etc).
- Class 9a – a health care building (eg a hospital, clinic, etc).
- Class 9b – an assembly building (eg community hall, sports hall, etc) Class 9c – an aged care building.
- Class 10a – a non-habitable building being a private garage, shed or the like.
- Class 10b – a structure (eg a fence, wall, mast, swimming pool, etc).
Building classes and the format of the BCA The BCA is split into two volumes. Volume One deals with buildings in Classes 2 to 9 and Volume Two, also known as the Housing Provisions, deals with buildings of Class 1 and 10. Volume One Volume One is split into nine sections with the first section containing administrative provisions, the remainder containing technical provisions.
Objectives – a statement that is considered to reflect community expectationsFunctional statements – statements of how a building achieves the objectivePerformance requirements – the level of performance a building solution must meet (ie the minimum standard)Building solutions – the way in which the performance requirements are met. The solution may be one that complies with the Deemed to Satisfy provisions or an alternate solution or a combination of both. The Deemed to Satisfy provisions are the ‘black and white’ solutions and if followed ensure compliance with the performance requirements. Alternate solutions allow for innovative design and use of materials and normally require certification by an expert in the particular field.
Section A: General Provisions – contains information such as definitions, how buildings are to be classified and the list of guidance documents such as Australian Standards that have been referenced by the BCA as Deemed to Satisfy solutions. Section B: Structure – requirements for the structural stability of the building including the structural resistance that materials and forms of construction must achieve against effects such as dampness, termites, water penetration, etc.
- Section C: Fire Resistance – requirements for the fire resistance of the building.
- This is to ensure that not only fire spread from one building to another is prevented but also a building maintains structural stability during a fire to allow for occupants to evacuate and the fire brigade to fight the fire.
This is achieved by separation distances between buildings, fire protection to external walls (including any openings such as windows) and the splitting up of the internal spaces of the building into separated compartments. It is important to understand the following terminology in relation to this section:
Type of construction – not to be confused with building class, this determines the level of fire resistance particular elements of the building must achieve. There are three types of construction, namely A, B and C, which are determined by the building’s class and rise in storeys. Type A includes buildings that have a higher risk such as high rise, high occupant buildings and is therefore the most fire resistant. Type C includes buildings that have a lower risk and is therefore the least fire resistant.
Fire source feature – this represents the potential location that fire may spread from or to. It is normally the external wall of another building on the same lot, a side or rear boundary or the far boundary of a road adjoining the lot. Boundaries are regarded as fire source features because the owner of one lot has no control over what is built on adjoining lots and there is potential for a building to be built up to the boundary on the adjoining lot.
Fire-Resistance Level (FRL) – measured in minutes, this is the resistance to the passage of fire an element of a building achieves. It consists of the criteria structural adequacy, integrity and insulation. For example, a 90/30/60 FRL represents an element that must achieve a fire resistance level of 90 minutes for structural adequacy, 30 minutes for integrity and 60 minutes for insulation.
Sole occupancy unit – this means a room or part of a building for occupation by one occupant to the exclusion of others.
Section D: Access & Egress – provisions relating to the number, size, type and separation of emergency exits, as well as the distance to an emergency exit. These provisions are determined by the building’s class, size of the building and the number of persons the building accommodates.
- The section also includes provisions relating to the accessibility of a building for people with disabilities.
- Section E: Services & Equipment – this section identifies the fire safety equipment that must be installed in a building.
- This equipment includes fire fighting equipment (eg fire hydrants, hose reels, portable fire extinguishers, etc), smoke hazard management (eg smoke detectors and alarms) and emergency lighting and signs.
The section also provides the requirements for lift installations when one is installed in a building. As a general rule all buildings require portable fire extinguishers to be installed. The provision of any other equipment is dependant on the size of the building.
Section F: Health & Amenity – the requirements for damp & weatherproofing, sanitary facilities, room sizes, light and ventilation and sound insulation. The number of sanitary facilities is dependant on the number of people the building accommodates. Provisions relating to sanitary facilities for people with disabilities are also included in this section.
The light and ventilation provision relates to both natural as well as artificial lighting and ventilation. Not all buildings are required to be provided with natural ventilation or lighting. Section G: Ancillary Provisions – this section contains requirements that affect structures that are ancillary to the main use of the building including minor structures (swimming pools, vaults, cool rooms), heating appliances (fireplaces, flues and chimneys) and atrium construction.
It also contains requirements for buildings constructed in alpine areas and bush fire prone areas. Section H: Special Use Buildings – the requirements specific to certain buildings such as theatres and public halls. Section I: Maintenance – the requirements for the maintenance of equipment in buildings.
_ Volume Two Volume Two is split into three sections, the first section containing administrative provisions, the second the performance provisions and the third the acceptable construction provisions. Section 1: General Provisions – this contains information such as definitions, how buildings are to be classified and the list of guidance documents such as Australian Standards that have been referenced by the BCA as Deemed to Satisfy solutions.
Section 2: Performance Provisions – this section is further split into five subsections entitled Structure, Damp & Weatherproofing, Fire Safety, Health & Amenity and Safe Movement and Access, Within each subsection the objectives, functional statements and performance requirements are stated. Section 3: Acceptable Construction – this section, also known as the Acceptable Construction Manual, contains the Deemed to Satisfy building solutions for Class 1 and 10 buildings.
The section is split into 11 subsections, namely Site Preparation, Footings & Slabs, Masonry, Framing, Roof & Wall Cladding, Glazing, Fire Safety, Health & Amenity, Safe Movement and Access, Additional Construction Requirements and Structural Design Manuals,

What is a 5 and 1 in construction?
5-over-1, also known as a one-plus-five, or a podium building, is a type of multi-family residential building commonly found in urban areas of North America, The mid-rise buildings are normally constructed with four or five wood-frame stories above a concrete podium (usually for retail or resident amenity space).
The name derives from the maximum permissible five floors of combustible construction (Type III or Type V) over a fire-resistive Type I podium of one floor for “5-over-1” or two floors for “5-over-2”, as defined in the United States-based International Building Code (IBC) Section 510.2. Some sources instead attribute the name to the wood framing of the upper construction; the International Building Code uses “Type V” to refer to non- fireproof structures, including those framed with dimensional lumber,
The style of buildings originated with the work of architect Tim Smith in Los Angeles, who took advantage of a change in construction code allowing the use of fire-retardant treated wood (FRTW) to construct buildings up to five stories. From this he saw that what became the “Five-Over-One” model would bring the construction costs down substantially, making a 100-unit affordable housing project financially viable.
