Blog - 16 : Erection and Hybrid construction

Fabrication and Erection:

  • Steel fabrication and erection is a lengthy process and it require more skills, knowledge and practice.
  • The erection of structural steelwork consists of the assembly of steel components in a frame on site. 
  • The processes involve lifting and placing components into position then connecting them together. 
  • Generally this process is achieved through bolting but sometimes site welding is done.


Erection issues:

  1. Incomplete, poorly coordinated and managed.
  2. Work complexity issues on the design.
  3. Significant quantity variation from original estimation.
  4. Slow drawing approval or significant drawing changes.
  5. Increased scope of work due to design changes and revisions.
  6. Cancellation or suspension of the work issues.

Hybrid Construction:

  • Hybrid construction is combination of steel and Concrete to form a quick, robust and safe form of construction that benefits from the advantages of both types of construction.

Benefits: 

  • Speed of construction
  • Saving in total construction cost.
  • Reduced on site labor requirements.
  • Better Health and Safety Because of products being manufactured offsite.
  • Better quality due to offsite manufacture.
  • Reduction in temporary works and deliveries to site

Spin wheel making

 SPIN WHEEL ACTIVITY  Isn't it boring to learn things in the usual way? How about learning it all through some fun activity !!! The spin wheel is very easy to make just by following few steps.  Materials required for making the spin wheel  Pens/ pencils Papers Scissors/ cutter  Glue Compass Ruler Pin/ thread The following are the 3 simple steps I followed in making the spin wheel :  Step 1 The papers shall be cut into 3 circles with required measurements. Step 2 Write necessary information in all the circles according to the spin.  Step 3 Arrange the circles in order and tie it using thread or just pin it.  The spin wheel is ready to be played with.  - Nandhini P

Hybrid

  Glass and Steel Construction: Glass with a density comparable to reinforced concrete presents modulus of elasticity almost equal to that of aluminium. Glass is several times weaker in tension than in compression. The fracture pattern of glass is highly dependent on residual stress. Annealed float glass breaks into large fragments whereas fully tempered glass presents high fragmentation and breaks into small pieces which does not affect post-breakage strength. Metal enforced glass beams: Comparing the load-bearing capacity of different glass beams in four configurations of glass strips: layered laminated, laminated segmented and laminated reinforced glass, Veer   has proved that even small amount of steel bonded to tensile side of a glass beam improves the post-breakage performance of the beam significantly. Carbon and glass fibre reinforced glass beams: A carbon fibre strip was bonded to the bottom edge of a glass beam with a structural adhesive. The main role of th...
