Does anybody know where can I find a case study for prefabricated building system R & D centre? Thanks.

Thesis: Prefabricated building system
Hello Dickson,

One of the prefab systems that is genuinly picking up strength in India is the ferrocement precast elements (roofing channles, walling panels, beams, etc.).
One of the buildings has been design & constructed at Delhi in 1998-99. (I was the architect). We unfortunately could not make columns in ferrocement.
This system is very good for lightweight, moderate strength projects. This building was built at an R&D centre.
For ferrocement, a lot of work has been done in India.

Thanks Chitradeep Sengupta for the response. Can I know what are the main spaces required for the R & D centre that u mentioned to build prefabricated building components?

Hello Dickson,

Typically, you need the following in a R&D centre to function for the kind of pre-fabricated system that I mentioned:-

1. Design studio (for designing various pre-fab elements)

2. Production centre for producing pre-tested as well as post tested & approved products.

3. R&D lab for doing basic testing.

Each of these 3 units have varying degree of sophistication & complexity depending upon the requirement.

For example the production centre can vary from low scale production by manual production to high scale production by totally mechanised processes.

Similarly R&D centre can be just an enhanced field testing centre to a sophisticated lab equiped with the latest testing gadgets.

So whatever you do has do be based on actual requirements. These include:-
1. Technology or technologies tat you are looking to produce;
2. Scale of operation (includes market demand, etc.);
3. Quality of operation including variation in quality.

Once you know these, it is easy to work out what the centre will have, how much area it shall cover, etc.

Thanks again Chitradeep Sengupta, that information really helps me a lot, and I am also looking a new technology to produce an adjustable prefabricated building components, I was thinking maybe we can share the ideas later.

Can anyone tell me about prefabrication techniques usable in open planned workspaces prefarably quick to construct and flexible in space planning?

Dickson,
Ok.

Harish,
are you talking about partitions, false ceilings, modular furnitures, exhibition space furnitures..etc?

Hello Dickson,

You can try for prefabricated building system and R & D centre at Auroville (Pondicherry). There lot of work has been done and going on. You will find it at Centre for Scientific research (CSR).

Thanks Laxmikant Surve, I'll try to find from there too...

Dickson,

I believe that micro-concrete roofing tiles are available in Malaysia. Is it correct?

Dear Chitradeep Sengupta,

Sorry for late to reply, yes indeed I had heard about it, although I am not familiar about it, but I know Mr. Tony Barry is the agent of this technology, his email is "tbarry@evalueco.com".

Hi Dickson,

Thanx.

I too have used it in many of my buildings & I am supposed to be an expert in it.

hi Chitradeep Sengupta,

that's great, do you know what's the cost of it, is it heavy? can it be any other building components?

Hi Dickson,

MCR tiles are used for sloping roofs of various shapes. There are actually various designs of MCR tiles themselves. However most popular are the Pan & Roman tiles. Actual variants vary from country to country. I believe that in Malaysia & Phillipines, the `Roman' tiles are more popular, whereas in India, the `Pan' tiles are more popular. PRime constituents are stone aggregates, coarse sand or micro-aggregates, cement. These are supposed to be economical, however you need to ask Barry for exact costing at your place.

MCR tiles in India has stiff competition from one of its own Swiss predecessor. These are called mangalore tiles. These are basically baked clay tiles which are red in colour and look very good. They also have very good strength & have been in India since 17th century (probably brought by the Spaniards then).

These are light weight (between 2-4 kgs per piece depending upon size, etc.) roofing tiles for sloping roofs.

Dear Chitradeep Sengupta,

Thanks for the useful information; I'll ask Mr. Barry for further information.
