Application in Affordable Housing Segment

  • Monolithic Concrete Construction Technology with Aluminum Form work – Construction Methodology
  • Mivan Shuttering Construction Technology

Mivan Shuttering is a fast-paced construction technology which offers strength and durability to a building by use of Aluminum Framework System.

With a growing focus on affordable homes and housing for all, there is increasingly emphasizing on the use of new and innovative construction techniques. One such technology is Mivan Shuttering which is being promoted for its ability aid mass construction activity. Its use is being promoted in India to realize the most ambitious government scheme – Housing For All by 2022.

Mivan Technology reduces the construction time by almost the half in comparison to conventional practices. It minimizes the need of skilled labour and completely eliminates the labour intensive activities such as masonry and rendering.

On the structural front, the technology makes the buildings more seismic-resistant and durable, since there are lesser number of joints, the building faces reduced leakages, hence requiring negligible maintenance.

There is uniformity in the Mivan construction and the walls and slabs, have a smooth finish. Moreover, the Technology gives the scope to take out more ‘carpet areas’ in comparison to conventional technologies.

USE OF MIVAN FRAMEWORK

  • 3S- System of construction – SPEED, STRENGTH & SAFETY
  • Column and beam construction are eliminated
  • Walls and Slabs are cast in one operation
  • Specially designed, easy to handle light-weight pre-engineered aluminum forms
  • Fitting and erecting the portion of shuttering
  • Carrying out concreting of walls and slabs together

ADVANTAGES

  • Mivan formwork requires lesser labor
  • More seismic resistance
  • Increased durability
  • Lesser number of joints and reduced leakages
  • Higher Carpet Area
  • Smooth finishing of walls and slabs
  • Uniform quality of construction
  • Negligible maintenance
  • Faster completion
  • More than 250 to 300 repetitions (reuse)
  • Fire resistant for two hours
  • Fast track construction technologies
  • Total units is made up of concrete which is stronger, durable and Solar Heat Resistant
  • Forms can be custom made to the requirements
  • Reduced cycle time
  • Better quality control at the site as lesser material mobilization at site
  • Cost effective
  • Plastering can be completely avoided
  • Forms can be placed in position even with the semi-skilled
  • Aluminum forms though costly works out to be cheaper with more number of repetitions

Fire Rating

As height of the building exceeds 15 m, then 2 hours fire rating is considered in the analysis and design of proposed structure.

Foundation

Conventional type of foundation such as ‘wall strip foundation’ / ‘Raft foundation’ based on soil conditions and safe bearing capacity of soil will be used.

RCC is the primary material used in this type of monolithic construction. Walls are designed as shear walls using limit state method as per the standard design equations given in IS 13920 and IS 456. Slabs are being designed as per IS 456. Element thickness (walls, slabs and beams) are chosen based on fire rating and structural requirements. Limit state of strength is used for the structural design of various elements of the housing units. Limit state of serviceability (stability, cracking and defection) will be used for ascertain durability criteria.

RCC is intended to be used in the proposed project guidelines confirming to the IS456, IS1390, IS 875, IS 1893 are followed to design the structure.

LIST of SOFTWARE

NISA/CIVIL Version 16 (Numerically Integrated Elements for System Analysis) developed by M/S Cranes Software International or ETABS will be used to analyze and design the proposed structure.

Wall Thickness (External) = 160 mm
Wall Thickness (Internal) = 100 mm
Slab Thickness = 125 mm/110 mm

 

GUIDELINES

1. IS 456: Plains and reinforced concrete codes of practice

3. IS 875 (Part 2): code of practice for design loads (other than earthquake) For buildings and structures Part 2, imposed loads
4. IS 875 (Part 3):   Code of practice for design loads (other than earthquake loads) for building and structures Part 3, Wind loads
5. IS 1893: Criterion for Earthquake Resistant Design of structures – Part 1, General Provision and Buildings
6. SP 16: Design Aids for Reinforce Concrete to IS 456- 1978
7. SP 34: Handbook on Concrete Reinforcement & Detailing
8. IS 13920: Ductile Detailing of Reinforced Concrete Structures Subject to Seismic forces.
