Latest Trends in High Rise Buildings / Skyscrapers Construction

Tall buildings past and present trendsSkyscrapers have been long part of urban cityscapes. They are typically found in busy and dense urban areas and are considered especially convenient for commercial and business areas.

Today, skyscrapers are an increasingly common sight where land is expensive, as in the centers of big cities, because they provide such a high ratio of rentable floor space per unit area of land.

History of High Rise

With our growing technological pace it is hard to imagine that the first skyscrapers were built in the 1880s! Although high rise apartments of over 10 stories have been found in Ancient Roman civilisations. The structural definition of the word skyscraper was refined later by architectural historians, based on engineering developments of the 1880s that had enabled construction of tall multi-story buildings. This definition was based on the steel skeleton as opposed to constructions of load-bearing masonry.

The American technological revolution of 1880 to 1890 saw a burst of creativity in architecture and civil structure technology. It produced a wave of new inventions that helped architects to build higher than ever before: Bessemer steel, formed into I-sections in the new rolling mills which enabled taller and more flexible frame design than the cast iron of the previous era; the newly-patented sprinkler head allowed buildings to escape the strict, 23-metre height limit, which was imposed to control the risk of fire; and the patenting of AC electricity allowed elevators to be electrically powered and rise to ten or more stories.

Need for High Rise

Reasons for taking the trend of constructing high rise buildingsAs urbanisation becomes a key aspect of modern living, the need for space is essential. Cities find it far more convenient to build vertically than to spread horizontally. This is a key factor in managing city infrastructure and makes it easier for the governing bodies to manage the demands of a growing population.

The design and construction of skyscrapers involves creating safe, habitable spaces in very tall buildings. The buildings must support their weight, resist wind and earthquakes, and protect occupants from fire. Yet they must also be conveniently accessible, even on the upper floors, and provide utilities and a comfortable climate for the occupants. The problems posed in skyscraper design are considered among the most complex encountered given the balances required between economics, engineering, and construction management.

Sustainability

In recent years the term Sustainability has turned from a trend to a necessity. Sustainability in the context of high rise buildings includes the built and natural environments, including the performance of structures, types of materials, construction practices, absolute minimal use of materials and natural resources, energy within the structure, and a holistically integrated building systems approach.

Sustainability covers economic benefit, resource efficiency, environmental protection and social development. Well developed building codes are now geared towards sustainability. It is common practice for local and central government to build committees to provide sustainability and environmental codes. These codes must keep in mind both sustenance and business in mind. The LEED certification is an internationally recognised green building standard that has found great acceptance around the globe.

Construction Jobs of the Future

Future of jobs in Australian construction industry‘Construction’ is an industry that has garnered tremendous growth over the last few years. Even in the periods where some of the other industries have faced pressure, there are no signs to suggest any slow down for this industry. The high rate of growth in the industry, in turn requires commensurate manpower to manage and drive this industry growth. This industry is creating more number of jobs than ever before. If you are in any way associated with this field, you are in luck!

Before we talk further about the kind of employment opportunities that construction industry can offer, let’s have a quick look at the sectors that it comprises.

The industry is broadly segregated in three main sectors:
  1. Building Construction
  2. Infrastructure Construction
  3. Industrial Construction

While the basics of the above three remain the same, work requirements, skill specialisations and employment opportunities differ across these sectors.

As the name suggests, Building Construction involves construction of residential or non-residential buildings. Residential construction includes building of houses/buildings from scratch, or carrying out small renovations such as addition of rooms in a house. The non-residential sector includes construction of commercial buildings such as offices, malls and marketplaces and institutional buildings like schools, colleges and other educational or vocational buildings.

The infrastructure construction sector covers the construction of highways, bridges, dams etc. Since the backbone of this sector is engineering, it is also referred to as heavy engineering sector. The infrastructure projects have a larger impact as they become a key impetus to the growth of an economy.

The third sector is the industrial sector. This includes construction of manufacturing plants, mills, chemical and power plants, refineries etc.

In the recent times, the requirement for construction workers has been on a rise. The construction industry can offer a wide array of job opportunities. From masons to carpenters, from civil engineers to construction managers, there are quite a few options available depending on your speciality of expertise.

With the increase in awareness about the construction process and the competition in the industry, construction agencies have become all the more important as they save the clients of most of the operational hassle involved in a construction project.

The changing market dynamics have also led to development of new construction methods and technologies. These aim at increasing the efficiency and performance and reduce environmental-damaging waste. These new methods have led to creation of new processes, which in turn has created many new construction jobs.

One such function that has come to the fore as a key one is that of a design team. The design team translates ideas, suggestions, requirements and design into reality. It can consists of architects, mechanical engineers, civil engineers, electrical and structural engineers, planning consultants, architectural consultants etc. Usually the property owners recruit their own design team. However, the incidence of agencies getting their own design teams to work on projects can also be seen quite often.

A construction project also requires people holding important roles such as construction managers, interior designers, accountants, mortgage bankers and cost engineers. Some of these functions are more salient in case of Infrastructure and Industrial construction projects.

There are many important semi-skilled or specialised construction jobs that you can look at. ProjectLink brings to you some of these options and their importance:

Essential Safety Equipment for Construction Workers

Basic personal protective equipment for construction workersEvery industry has its unique processes that involve both, humans and machines. All these processes pose some hazards which require unique safety measures. However, there are some risk factors that are common for all sectors. These risk factors can turn out to be life threatening, if proper precautions are not taken.

Construction and mining sites are no exception to the risk of hazards, be it huge or small. Though the industries have advanced their processes and with high technology, there is always a risk to human life at the sites. This makes it imperative for both, employers and employees to follow a strict protocol for safety precautions.

Here is a list of some of the basic personal protective equipment (PPE) for construction workers:

Eye and Face Safety Equipment

Wear protective eye and face gears to stay safe at workThe eyes and face are most sensitive parts of the body and hence they need utmost precaution at construction sites. Majority of eye injuries take place due to foreign particles, gasses or objects that get into the eyes while welding, cutting, grinding, nailing, working with concrete etc. Working at sites with extreme winds, sparks, smoke, or dangerous chemicals also requires high precautions and safety equipment.

The essential safety equipment may vary according to the kind of work one is assigned to. For instance, stringent safety measures need to be adhered to by people working in close vicinity of welding machines or any acidic substance. There are many safety gears available in market that are specifically designed to be used for certain tasks. Based on safety requirements of various industries, ProjectLink has listed out the top eyes and face protection gear to choose from.

Head Protection

Hard hats are essential to protect head from major injuriesConstruction worker or not, if you are even walking through a site while the work is in progress – you have to wear a hard hat. This is the most important and fundamental requirement for any construction site. At construction sites, there is always a risk of objects falling from heights, and causing serious injury to your head. The hard hat is a vital gear that shields workers or visitors from falling object and/or direct contact with any harmful material. These hats are also useful for a protection from rain, direct sun rays, and electric shock.

Predominantly these hard hats are made of high density polyethylene (HDPE) or advanced engineering resins, like, Ultem. They are capable of protecting person’s head from major injuries. Many of these hats also designed with accessories like face shield, hearing protection and ventilation to keep the wearer comfortable. Other advanced accessories that can be attached to these hats include, radio, walkie-talkies, mirrors, lights, cameras etc.

It is essential to keep these hard hats in good condition, and immediately replace them in case of any damage.
