Steel structures can be erected speedily, the predictability and accuracy of steel components speeds up the process and allows follow-on trades to get to work sooner.

This delivers time savings in the build programme compared to a concrete frame. In fact, speed of erection is often one of the main criteria for selecting steel.


- Faster construction, more control over the project’s time flow.

- More efficient project management

- Steel can be assembled efficiently and quickly in all seasons.

- Prefabrication speeds up the assembly, steel structure buildings can be erected in a matter of weeks rather than months with a 75%-time reduction compared to traditional on-site construction.

Steel is one of the most generally utilized materials of construction time. Without steel, the structure does not make a definite while seismic tremors like earthquakes happen. Steel structures are susceptible to various ecological conditions.

There are a few properties wherein concrete designs are preferred over steel. The utilization of steel is consistently expanding everywhere globally in development projects and civil engineering-related fields.

The utilization of steel in development building became a common practice, the weight of the structure material and the forces of gravity and pressure defined the endurance, chance of stability in structure, and its architectural possibilities.

In many inner-city projects, it is also important to reduce disruption to nearby buildings and roads. Short construction periods lead to savings in site preliminaries, earlier return on investment and reduced interest charges. Time related savings can easily amount to between 3% and 5% of the overall project value, reducing the client’s requirements for working capital and improving cash flow.

Structures that need to be built quickly should be designed of prefabricated components as much as possible. While being functionally efficient, it would also meet erection effectiveness requirements. The process effectiveness of a structure is a degree of feasibility of its manufacture, transportation, and erection with minimum consumption of materials, labour, and other resources.

The erection effectiveness is ease of erection with minimum consumption of labour, time, and other means. Characteristic of erection effectiveness are an efficient pre-assembly of structures, relatively equal weights of erection units, high degree of prefabrication and accuracy of manufacture, and last but not the simplicity of butt joints and provision of fastening devices.

Erecting structural steelwork for building construction takes place in a dynamic, changing environment where there are many hazards and risks.

Proper and timely planning and coordination are the most effective ways to manage those hazards and risks. Projects involving structural steel construction have four main stages where risks to health and safety need to be considered:

- Design,

- Fabrication,

- Transport,

- Erection

The erection of component structures involves preparatory and main stages.

The preparatory stage includes transportation, storage, and pre-assembly, whereas the main stage of the erection work comprises preparation for lifting, lifting, and temporarily fastening structures, grouting joints and applying anticorrosion coats. Schematic of erection work organization

It is important to ensure that challenging steel structures are matched with strong fabrication capabilities.

As much as possible of all fabrication processes should be carried out in the fabrication yard. Relevant and crucial equipment such plasma cutting, and robotic machinery are available to maximize productivity and realize the highest degree of quality, accuracy, speed, and safety in cutting, shaping, holing, welding, bending, and joining work.

Some fabrication equipment is best numerically controlled. It may be important to ensure a genuine seamless CAD/CAM environment, by linking computer-aided design and detailing (CAD) directly to the factory floor numerically controlled machinery computers (CNC).

Steel structures must be well-treated through the following processes:

- Surface preparation.

- Corrosion protection by galvanizing or painting work.

- The hot-dipped galvanized coating is applied for harsh environments
