Mivan framework system Vs Conventional method of construction:

The Mivan framework system compared with the Conventional system is something that everyone one must know about.

 So, for the people who don’t know what either of the topics are... The conventional method of construction is the Brickwork method. This method has been used for a very long time! Hence it is called the Conventional method of construction. Now, when we speak about the Mivan method of Construction... It is the advanced way of construction for the modern world.

  While using the conventional method of construction the cost of getting the job done was very high as it took longer to construct and because of which labour cost also increased. The speed of development in case of conventional construction for one floor is about 21 days when you compare the same with Mivan method of construction is just a mere 7 days. 

 Now, when we talk about even quality... With conventional systems the strategy for development is ordinary so there is a very ordinary quality of work. With the Mivan method of construction there is superior quality of construction due to in-stu throwing of the entire structure and transverse division done in constant operation. 

  When we talk about the maintenance required for conventional systems... It is really Very high as it requires regular repairs of mortars of the wall, painting of internal and external walls due to water leakage when we compare the Mivan system of construction the maintenance is almost negligible as there is superior concrete used that requires almost no repairs. Even if we compare the quality of finish the Mivan system gives you an excellent finish in which putting is not required... With conventional systems the finish is very bad and for that reason putting is required.

 Even the safety features that come with the Mivan system of construction is superior as it is much more resilient to earthquakes as compared to the conventional methods of construction. Also, if you ever plan on changing the floor without expelling the props it is possible with Mivan and not with conventional methods of construction. 

We can conclude by saying that the Mivan construction system has all the elements needed for meeting the demand for efficient and sustainable housing. Quite a few properties these days have chosen this method of construction in India itself! 

Mivan Formwork erection process:

·        Placement of Aluminium Formwork

·        Mivan formwork is majorly used in the places where the whole structure is made of concrete.

·        All formwork is cleaned and coated with approved real agents.

·        The wall reinforcing steel is placed with the floor slab.

·        Along with the wall reinforcing steel, prefabricated room-sized walls panels and floor slab panels are erected.

·        Plumb, level, and dimensions are checked.

·        The aluminium alloy slabs are accurately made as per the required sizes.

·        Spaces for windows, ducts, doors and other features such as staircases, façade panels, and chajjas are also integrated into these structures.

The forms are then joined together using the pin and wedge system, which can be dismantled quickly after the concrete structure is made.

2. Pouring of concrete.

·        After casting the forms, high-quality concrete is poured.

·        This concrete takes the form and shape of the cast.

·        At least two operatives should be on standby during concreting for checking pins, wedges and wall ties as the pour is in progress.

·        Special attention to be given while pouring concrete for dislodging of pins/wedges, slipping of props or overspill of concrete at openings.

3. Striking of Framework.

·        Normally all formwork can be struck after 12 hours of concreting.

·        First, the wall formwork is struck down, followed by deck formwork.

·        The removed formwork is cleaned with scrapers and wire brushes as soon as they are struck.

·        Once cleaned, it is transported and stacked properly for the next use.

Speaking about the features of the Mivan Framework...

1. Load Carrying Capacity... The load-carrying capacity of Mivan formwork is 7-8 Tonnes per square meter. Mivan formwork is lightweight and weighs around 18-20 kg per meter square.

2. Striking Time... The striking time of vertical (wall) formwork is 12 hours after concreting or when concrete strength has reached 2N/mm2 and horizontal (deck) formwork is 36 hours after concreting or when concrete strength has reached 10N/mm2.

3. Durability... As the panels of Mivan formwork are made of structural grade aluminium alloy, they are very durable and sturdy. A single component can be repeated around 200 times.

4. Cycle Time High speed of construction can be achieved by this system that means faster completion of the project. Approximately, the times required to cast floor is 7 days with the use of Mivan formwork

There are several advantages of builders going the Mivan way. A few of them would be: High-quality formwork ensures consistency of dimensions.

·        On removal of the mould, a high-quality concrete finish is produced to accurate tolerances and verticality.

·        The total system forms the complete concrete structures.

·        Custom designed to suit project requirements.

·        Unsurpassed construction speed.

·        Panels can be reused up to 250 time

·        It can be erected using unskilled labour.

As there are advantages it would be to follow the laws of nature for it to have disadvantages as well... a few of the concealed services become difficult due to the small thickness of components.

·        It requires uniform planning as well as uniform elevations to be cost-effective.

·        Modifications are not possible as all members are caste in RCC.

·        The large volume of work is necessary to be cost-effective i.e., at least 200 repetitions of the forms should be possible at work.

·        The formwork requires a number of the spacer, wall ties, etc. which are placed @ 2 feet c/c; these create problems such as seepage, leakages during monsoon.

·        Due to box-type construction shrinkage cracks are likely to appear.

·        The heat of hydration is high due to shear walls.

Affordable housing projects were given a major boost this year in the Union Budget 2017-18. Since the affordable housing sector is the most incentivized segment for both developers and buyers, many reputed developers are now launching projects in the affordable segment. More than 10 million affordable houses are expected to be built in rural India by 2019. This is a huge opportunity to showcase the value of Mivan technology.

roperty prices fluctuate due to a complex interplay of economic, demographic, governmental, and social factors. Understanding these dynamics can help stakeholders make more informed decisions.
