What Is Mivan Technology?

Factually, Mivan is an aluminium formwork system manufactured by Mivan Company Ltd, Malaysia in the year 1990. This innovative form of work is quite suitable for constructing houses in large volumes at a faster speed.

In technical terms, a huge number of houses can be constructed at much faster speed using Mivan shuttering as this system of formwork construction runs the structural system in one continuous pour. When the formwork is removed a high-quality concrete finish is shaped with precise tolerances and verticality which invalidates the need for additional plastering.

This construction technique involves 3 unique steps:

Setting Up The Wall Reinforcing Steel – This is used to provide structure to the building and support the concrete till they gain 50 percent of the essential strength. The aluminium formwork is cast around the factory-made steel mesh which is directly erected on the construction site.
Placement Of Aluminium Formwork – Along the wall reinforcing steel, prefabricated floor slabs, and room-sized walls are erected. The aluminium alloy slabs are very easy to handle and are also very precisely made. These are also pre-integrated with spaces for, windows, doors and ducts, other features like chajjas, staircases and façade panels are also integrated. The pin and wedge system is used to join these forms, these can be quickly dismantled once the concrete structure is ready.
Pouring Of Concrete – After the forms are cast, high-quality concrete is poured in which takes the shape and form of the cast. The cast is later removed to make way for a hard-concrete structure supported by wall reinforcing steel. These aluminium forms can be reused for nearly 250 times, which means minimum wastage from the construction site.

MIVAN is perhaps one of the most useful modern construction technologies introduced in the Indian markets. This technology is designed to permit rapid construction of several unit projects and surge efficiency.

Merits And Demerits Of Mivan Technology

Shortage of construction manpower and mounting costs has forced the developers to try new technologies. Considering Mivan, this technology is very well suited for high-rise buildings with typical floors saving time as well as money as compared to the conventional column beam construction methods. However, along with the advantages, this technology does scores on a few negatives too; let’s take a look at both merits and demerits of Mivan.

Merits Of The MIVAN Technology

Speed – Reduces the total turn around time by almost half when compared to conventional construction techniques.
Demands Less Labour – With a set procedure and checklists to follow, this technology minimizes the need for skilled labour and also eliminates activities like masonry and rendering activities which are labour intensive.
Seismic Resistant & Durable – The buildings are more seismic resistant and more durable.
Less Maintenance – Primarily with no construction joints and with free flow concrete used, this technology reduces the chances of seepage which further results in negligible maintenance.
Smooth Finish – Mivan construction ensures uniformity, hence all walls and slabs have a smooth finish which means additional plastering is not needed.
Higher Carpet Area – it gives the scope to take out more carpet area in comparison to traditional construction techniques.
Earthquake Resistant – More earthquake resistant structure and safer in case of a strong earthquake. This is because structures built using Mivan is a monolithic concrete structure which acts as a whole single strong unit.

Irrespective of so many attractive advantages, the demerits of this formwork cannot be ignored. Let’s take a look at them now:

Demerits Of The MIVAN Technology

Expensive – Aluminium formworks are much expensive than the conventional formworks.
Visible Finishing Lines – Because of small-sized components, the finished structure could have several finishing lines visible on the concrete surfaces.
Less Scope Of Alterations – Alterations or modifications are not possible as all the members are cast in RCC.
Demands Uniform Planning – This technology is comparatively expensive, to be cost-effective uniform planning as well as elevations are needed.

The New Age Construction Technology Mivan

Increasing number of builders have been already using this technology and many are following their footsteps. Change is foreseeable in the real estate industry. The new gen developers are giving the required thrust to these new construction technologies which in turn is providing the much-needed global shape to the construction industry. Today, more and more emphasis given to quality consciousness and timely delivery of projects giving motivation to the switch from conventional to innovative methods like Mivan. But again, such construction methods mean huge investments and are not feasible for small construction projects.

Some of the popular Indian developers using MIVAN technology are Shapoorjii Group, Oberoi, Lodha group, Golden Gate Bangalore, Marathon Group etc.

Procedure of MIVAN Formwork Construction:

The construction procedure of MIVAN formwork is similar to the traditional type of formwork. The following Process are involved in the MIVAN Construction:

1. Setting up the Wall reinforcing steel:

In this step, the wall reinforcing steel is used to form structure to the building, This reinforcement steel gives support to the concrete till it reaches 50% of designed strength. This steel mesh is Pre-casted in factory itself and can be easily erected on construction site.

2. Placing formwork:

As mentioned, MIVAN formwork is a ready-made one, Formwork is designed and manufactured in factory itself as per the required sizes of slabs, columns, beams, staircase and other structural elements of the buildings. By Pin and wedge system formwork is easily assembled on site. Formwork can be easily dismantled from the structure once the job is done.

3. Pouring concrete:

Once the formwork is placed, Freshly made concrete is poured inside the formwork to form the shape. Once the concrete gains required strength, the formwork is dismantled from the structure.

Simplicity – pin and wedge system in MIVAN aluminium formwork :

The beams are held in position by a simple pin and wedge system that passes through holes in the outside rib of each panel. The panels fit precisely, simply and securely and require no bracing.
