INTRODUCTION Mivan technology is a fast-paced construction

technique by using aluminium formworks. Mivan is an aluminum formwork system developed by a European construction company.

In 1990, the Mivan Company Ltd. from Malaysia started manufacturing these formwork systems.

To facilitate fast construction, early removal of forms. Mivan Formwork 3

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 OF MIVAN FORMWORK  Fast construction is assured and is particularly suitable for large magnitude construction of respective nature at one project site. Construction carried out by this system has exceptionally good quality with accurate dimensions for all openings i.e., doors & windows. .Concrete surface finishes are good to receive painting directly without plaster.

System components are durable and can be used several times without sacrificing the quality or correctness of dimensions and surface.  As all the walls are cast monolithic and simultaneously with floor slabs requiring no

further plasters finish. Therefore the time required in the conventional method for construction of walls and plastering is saved.

5

LIMITATIONS OF MIVAN FORMWORK It requires uniform planning as well as uniform elevations to be cost effective. 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. The formwork requires number of spacer, wall ties etc. which are placed @ 2ft c/c; these produce problems such as seepage, leakages during monsoon. Services after completing become slightly difficult.

CONCULSION OF CASESTUDY  It’s well known that the Mivan Technology reduces the cost of construction from above analysis, hence the technology is useful to the construction company and builder.  MIVAN formwork played a vital role in the construction of the project. The project

was completed not only on stipulated period of time but also paid off with its attributes. Speedy & quality dwelling units were provided to the people of low income groups at very reasonable costs. MIVAN is a definitely future of this ever

growing construction industry with lots of project still awaiting its touch of excellence. 12

SUMMARY  Civil engineers not only build but also enhance the quality of life. Their creativity and technical skill help to plan, design, construct and operate the facilities essential to life. It is important for civil engineers to gain and harness the potent and versatile construction tools.  MIVAN serves as a cost effective and efficient tool to solve the problems of the mega housing project all over the world. MIVAN aims to maximize the use of modern construction techniques and equipments on its entire project.  Thus it can be concluded that quality and speed must be given due consideration with regards to economy. Good quality construction will never deter to projects speed nor will it be uneconomical. 13
