BLOG 16 - FABRICATION, ERECTION AND HYBRID CONSTRUCTION

 Steel fabrication, erection and hybrid construction

Fabrication:

In fabrication methods such as grinding, welding, cutting, bending, drilling, punching, burning or melting are involved.

High quality tools and Computer Numerical Controller equipment is also used.

Crucial steps and measures are needed to be done in this process.

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

Structures have to be specifically designed and fabricated before constructing and assembling them together.

 

Steel erection:

 Erection is done with the help of cranes or by jacking and lifting and placing components.

Bolted connections are done to keep the components secure and bracing is also done.

Structure alignment is essential by checking the column bases to be lined and levelled.

The process involves lifting and placing an exact position by connecting together.

Connections may be achieved by bolting, welding, and sometimes riveting.

Erections may be achieved by two techniques such as MEWP(Mobile Elevating Work Platforms) by Mobile crane and Tower cranes.

 

 Both of the above process require knowledge, high skills and practice and might be lengthy

 

Hybrid construction involves combining different materials or techniques in one structure like a combination of steel and wood in a concrete structure.

The exterior structure has been prevented by galvanizing coating or other waterproof membranes on it.

 This type of constructions has done through proper design strategies.  Linked hybrid by Steeven Holls and Brentwood station by Busby associates is a good example of hybrid constructions.

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...

BLOG- 8                                     STEEL , ALLOYS AND THEIR COMPARISON                                                               STEEL AND ALLOYS                                               An alloy is a blend consisting of metal and other elements. 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. Definition ALLOY :      A homogeneous mixture of a metal with other types of elements                       ...
