Mivan is basically an aluminium formwork system developed by one of the construction company from Europe. In 1990, the Mivan Company Ltd from Malaysia started the manufacturing of such formwork systems.
The technology has been used extensively in other countries such as Europe, Gulf Countries, Asia and all other parts of the world. MIVAN technology is suitable for constructing large number of houses within short time using room size forms to construct walls and slabs in one continuous pour on concrete.This facilitates fast construction, say two flats per day. All the activities are planned in assembly line manner and hence result into more accurate, well – controlled and high quality production at optimum cost and in shortest possible time.
In this system of formwork construction, cast – in – situ concrete wall and floor slabs cast monolithic provides the structural system in one continuous pour. Large room sized forms for walls and floors slabs are erected at site. These forms are made strong and sturdy, fabricated with accuracy and easy to handle. They afford large number of repetitions (around 250). The concrete is produced in RMC batching plants under strict quality control and convey it to site with transit mixers.
The frames for windows and door as well as 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.
The method of construction adopted is no difference except for that the sub – structure is constructed using conventional techniques. The super–structure is constructed using MIVAN techniques. The integrated use the technology results in a durable structure.
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.
