Construction is an ever-evolving sector of human living. Thus, new skills, materials and styles keep coming up, and it is highly necessary for a person in the industry to keep abreast with them. There are new processes, technologies and ways of working. Construction and design firms seek dynamic people who are up-to-date and can execute projects profitably in the least possible amount of time. Hence, construction training and education are key.

It is true that there are a lot of people in the construction industry, however, only a handful of the crowd can boast of up-to-date training.

Modern construction is not about dirty and dangerous sites with hundreds of builders on scaffolds. It now involves harnessing technology to make things faster and easier. Materials like steel make this work out as steel parts can be more easily pre-designed for easier erection and assembly.


Steel frame is a technique in building in which a skeletal frame of vertical steel columns and horizontal l-beams, erected in a rectangular grid to support the roof, floors and walls of the building which are affixed onto the frame. This technique has facilitated the construction of skyscrapers.

The cross-section or profile of the columns is made of rolled steel shaped like an “L”. Both flanges on each column are thicker than the flanges on the beams for resistance against compressive stress in the steel frame building. Round and square tubular steel sections, often filled with concrete, could also be used. Bolts, threaded fasteners and rivets are used to connect the beams and columns together. The immense strength, flexibility and ductility of steel make it of great advantage in construction, as failure in steel frame structures is not sudden. Hence steel structures rarely collapse.

Nissen huts are prefabricated steel structures of corrugated steel used for military housing purposes. They are made from a metal sheets bent into half cylinders. The Nissen hut was first designed during the World War I by Major Peter Norman Nissen, an engineer and inventor, and used significantly during World War II. The Nissen hut is a perfect example of a building style that has stood the test of time and remained relevant through the years, howbeit with some improvements. The steel huts have several advantages and are still in use today as workshops, chapels, clubhouses and homes.

Steel frame buildings serve as:

  • High rise buildings: because of the strength, light weight and speed of construction of steel.

  • Industrial buildings: because of the low cost of large spans of steel.

  • Warehouse buildings: the same reason as above.

  • Temporary structures: because pre-designed steel beams can be quickly set up as well as taken down.
