What is Mivan Formwork?

Mivan is an aluminium formwork system developed by a European construction company. In 1990, the Mivan Company Ltd. from Malaysia started manufacturing these formwork systems. Today, more than 30,000sqm of formwork from Mivan Co. Ltd. is used across the world. There are a number of buildings in Mumbai that are being constructed with the help of the Mivan system, that has proven economical as well as satisfactory for the overall Indian construction environment. One of the architectural examples is XRBIA which uses MIVAN system to achieve its dream of “A House for Every Indian”

The technology has been used extensively in Europe, Gulf Countries, Asia and other parts of the world. Mivan technology is suitable for constructing large number of houses in a short span of time using room size forms to construct walls and slabs in one continuous pour on concrete. In this system of formwork construction, cast–in–situ concrete wall and floor slabs cast monolithic provides the structural system in one continuous pour. To facilitate fast construction, early removal of forms can be achieved by hot air curing / curing compounds. Large room sized forms for walls and floor slabs are erected at site. These strong and sturdy forms are fabricated with accuracy and are easy to handle. The concrete is produced in RMC batching plants under strict quality control and convey it to site with transit mixers.

The frames for windows, doors and ducts for services are placed in the form before concreting. Staircase flights, façade panels, chajjas and jails etc. and other pre-fabricated items are also integrated into the structure. This proves to be a major advantage as compared to other modern construction techniques. High quality Mivan Formwork panels ensure consistency of dimensions. On the removal of the formwork mould a high quality concrete finish is produced to accurate tolerances and verticality. The high tolerance of the finish means that, no further plastering is required.

Uses of Mivan Formwork:

  • 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 aluminium forms
  • Fitting and erecting the portion of shuttering
  • Carrying out concreting of the walls and slabs together

Advantages:

  • Mivan formwork requires relatively less labour
  • More seismic resistance
  • Increased durability
  • Lesser number of joints and reduced leakages
  • Higher carpet area
  • Smooth finishing of wall and slab
  • Uniform quality of construction
  • Negligible maintenance
  • Faster completion

Limitations:

Even though there are so many advantages of Mivan formwork the limitations cannot be ignored. However the limitations do not pose any serious problems. They are as follows:

  • Because of few small sizes finishing lines are seen on the concrete surfaces
  • Services after completing become slightly difficult due to the small width of components
  • It requires uniform planning as well as uniform elevations to be cost effective
  • The formwork requires number of spacer, wall ties etc. which are placed @ 2ft c/c; these produce problems such as seepage, leakages during monsoon
  • Due to box-type construction, contraction cracks are likely to appear
  • Heat of hydration is high due to shear walls
  • It is rigid in design once placed, as any alteration becomes tough later
