 FABRICATION, ERECTION AND HYBRID STRUCTURES

FABRICATION:

Fabrication is the process used to manufacture steelwork components that will, when assembled and joined, form a complete frame. 

The process of steel fabrication involves grinding, welding, cutting, bending, drilling, punching, burning or melting, and other general crafting methods using various high-quality tools and CNC equipment.

The entire steel fabrication process is systematic and requires the utmost planning, precision, and knowledge. Steel fabricators are well aware of all the crucial steps and measures that need to be taken care of in the fabrication process.

 Structural steel is usually fabricated to create structures like beams, trusses, hollow sections, angles, and plates.

ERECTION :

The erection of structural steelwork consists of the assembly of steel components into a frame on site. The processes involve lifting and placing components into position, then connecting them together. Generally, this is achieved through bolting but sometimes site welding is used. The assembled frame needs to be aligned before bolting up is completed, and the structure handed over to the principal contractor.

ERECTION CONSIDERATIONS:

  • establishment of the foundations and check if they are suitable and safe for erection 
  • to secure the components in place, bolted connections are made but are not fully tightened. Similarly, bracings are not fully secured.
  • Aligning the structure is essential, principally by checking that column bases are lined and leveled
  •  completion of all the bolted connections to secure and impart rigidity.


HYBRID CONSTRUCTION:

Hybrid construction is a combination of different materials or techniques to design a range of building types. 

ADVANTAGES:


  • Speed of construction
  • Prelim savings
  • Reduced on-site labor requirements
  • Enhanced Health and Safety with H&S measures being incorporated into products manufactured offsite
  • Better quality due to offsite manufacture
  • Reduction in temporary works and deliveries to site
  • Enhanced program monitoring from initiation of design through to completion of works on site giving certainty of project delivery.

Steel Erection, Fabrication and Hybrid construction -Blog 16

This blog is about how the steel sections are transported to the site, the issues involved with transportation, erection and fabrication along with the onsite constrains. TRANSPORTATION: The steel sections have to transported from the manufacturing site to the fabrication site and this becomes a tough task due to their size. Often large pieces cannot be transported in a single part, they are split or divided and shipped as two separate pieces or even as one piece to avoid damage or scratches. Temporary connections are made on the pieces to avoid damage and to keep the parts in place during transportation.     These parts are not transported in normal vehicles but require long trail vehicles to fit their length and size which again becomes a difficult task to turn around the corners of the road and at junctions     FABRICATION & ON SITE CONSTRAINS: Fabrication of steel on sites which are along the main road or at the corner site is very hectic as there is very...

Environmental impact of steel

Steel is important for construction,but it also affects the environment.The world produces a lot of steel over 240 kilos for every single person in the world every year .Steel production is one of the most energy consuming and CO2 emitting industrial activities in world. Environmental impact of steel production: Mining of iron ore : the main raw material for steel is iron ore is mined a year about 95 percent is used by the steel industry. The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide,carbon dioxide,carbon monoxide,sulfur dioxide from diesel generators,trucks and other equipment. The mining of iron ore also cause water pollution of heavy metals and acid that drains from the mines.Acid drainage can go on from thousand of years after the mining activitie...

Alloys are generally made for achieving properties like greater strength or resistance to corrosion. Steel is an alloy of iron. It mainly consists of iron with some small amounts of carbon.
