The building materials are as follows: 2,500kg of cement, 1,500 litres of water, 5kg of gravel, 3,000 litres of earth and 100 tonnes of sand.
The cost is Rs 10,000 for a single slab, Rs 10 for the slab with the whole roof and Rs 10 to construct the whole building with the slab.
The roof pitch, which is also referred to as the foundation or base, is an integral part of the roof structure and has to be designed by an architect and is made from a combination of stone and concrete.
The roof pitch must be square and triangular and it must have at least three horizontal segments.
The vertical segments must be at least six metres in length.
The base of the structure is made of the concrete slab and the rest of the building is made out of the slab and cement.
It is also recommended that the slab be of a solid and flexible material.
In the past, the roof pitch was a very difficult construct to build and it was not uncommon to spend up to two months in a row to get the roof to a point where the foundations were ready.
With the advent of solar power, the cost of the foundation is falling and the cost per square metre has gone down.
The cost of roof pitches for a residential project in Mumbai has fallen to Rs 1.5 lakh.
A project with the base will cost Rs 1 crore.
However, the amount of cost is much lower for projects with the roof base.
A large slab will cost around Rs 10 crore, whereas a smaller slab will be around Rs 5 crore.
The project will be carried out in four phases.
The first phase is to lay the foundation and the second phase is for the roofing of the ground floor.
The third phase is the roof construction and the fourth phase is finishing the roof.
This project costs around Rs 4 crore.
A roofing project for a two-storey building, a three-storeys building, or a four-storeies building will cost about Rs 15 crore, Rs 12 crore, and Rs 17 crore respectively.
The construction cost for the project is also very expensive.
The contractor has to go through a lot of tests to ensure that the building can withstand the earthquake.
A major problem in the construction of a roof is that the roof is not made out entirely of cement.
This is because the concrete in the cement is brittle.
This means that the structure cannot hold up to the earthquake because the slab will break apart.
The contractors must therefore build a composite slab, which will hold up the structure in the earthquake and withstand the stress of the shaking.
The final cost of a rooftop project is about Rs 5 lakh.
To construct a roof, the contractor must go through the process of creating the structural foundation, the foundation material, the cement, the slabs, the base, the structural steel, the drainage system and the drainage lines.
The total cost of this project is around Rs 12 lakh.
The construction costs are not cheap.
There are different kinds of roof materials, like cement-concrete-lumber-sand-stone-concealed concrete and other materials.
The process of constructing the roof can take anywhere from three months to two years.
The concrete slab is also constructed in this time.
The foundation for the structure and the base for the building are also constructed.
The building is then completed.
The project is carried out for one building.
However it can be done for multiple buildings.
There is no limit to the number of units that can be constructed.
For instance, there are two two-story residential blocks with a base and roof.
It will cost between Rs 10 and Rs 25 crore for the two-level residential block and Rs 15 and Rs 20 crore for one-story building.
The whole building will then be completed in a day.
