Approval Procedure Cycle.

Do you want cycle in every 20 years ?

Approval Procedure = Monopoly + Power - Transparency

We can Reduce Approval Procedure by Simple Bye-laws Power to Architect On line Procedure Sustainable Construction for at least 100 years maintenance free & Green Building for M.o.E.F. Approvals.

More People DieDue to more food

Than Less Food

More Buildings

Collapse

Due to Self Load

Although we have high strength concrete & steel then why are the beams, columns, slabs, of our Buildings NOT comparably of smaller size than (1:2:4:) M15 in olden days? & steel quantities reduced?

Are we designing Buildings to take care mostly of self load ??As of now about 90% self load takes care of only about 10% live load.Can the self load be reduced by hollow, light weight members?

R.C.C. Life…..50yrs.

Green Load bearing Houses Must Be Attractive Economical Eco Friendly Proven Simple Speedy Sturdy Sustainable

While Planning the Building it is more Appropriate To Work Out Which is the Most Suitable Construction Method and Plan as per the Technology. R.C.C., STEEL, PRECAST , RIB SLAB. Aluminum-ShutteringR.C.B. (Reinforced Concrete Block Masonry.)

Affordable Due To Optimum Planning Detailed Designing Detailing of each Joint Appropriate Technology

PLANNING

More common walls Least number of notches Least wall area / Floor area ratio Complete detailing for each member Minimum number of staircase Least common passages Least foot print & loading

10% More Carpet Area. So Most Affordable

LESS OFFSET, MORE COMMON WALLS

TOTAL COST WITH FINISHING For R.C.C. …….. Rs. 1000/- per Sqft.

For Aluminum Form ..Rs. 1200/- per Sqft. For R.C.B . ………Rs. 700/- per Sqft.

1) R.C.C. type of construction was taught by British & we are following Beam & Column type of construction for the last hundred years or so in India. 2) R. C. C. building needs repairs within 15 years of construction.Not that anything is wrong with R. C. C. but there is more scope to use inferior material & workmanship in R.C.C.& hence need for early repair. 

3) Our Forts, Old buildings, V. T. Station, Municipal Bldg., Palaces, Towers are generally constructed by Stone Masonry load bearing method & have stood since hundreds of years without any major repair work. 4) The same load bearing technology has been further developed in U.S.A. which is Speedy, Sturdy, Simple, Durable, Eco-Friendly which also saves 30% in construction cost & is called R.C.B./ Reinforced Masonry/ C.M.U.

Method Of Construction

Concrete block 8” X 8” X 16”

Ultimate strength = 40,000 Kg/block

As Air is freely available and Hollow Concrete Block is 50% hollow, if a structure is built by R.C.B. the cost of construction is slashed down.

In India 300 buildings have been designed by R.C.B. method in the past 30 years by us.

In the world millions of buildings have been built by this established & proven American technology in the past 90 years.

Note : By Optimized Plan get 10% more Carpet Area.

Advantages of R.C.B. Method. Economy : As steel, cement, formwork, concrete & Labor

required is almost half & due to simplicity of construction & speed, minimum saving is Rs. 300/- per sq. ft. Also by optimum planning for R.C.B. get up to 10% more carpet Area.

Speed: No heavy equipment needed on site, less formwork, less steel so construction is simple, speedier & hence economical.

Fire Resistant : Due to concrete block & 3.5" cover to steel, rusting is minimized & such buildings are fire resistant too.

Durable: Concrete blocks are attractive, durable and have excellent thermal, acoustic properties. No repair like R.C.C. is needed in every fifteen years.

Earthquake: Load bearing concrete blocks can be designed to be wind, earthquake resistant too. Up to 22 Storied.

Warranty: R.C.B. Method assured warrantee against heavy rain, flood, fire, storm, earth quake & all other natural calamities for at least 50 years.

Architecture: Ancient type of architectural elevation is also possible by R.C.B type of construction. Also R.C.B. is Environmental friendly too.

R.C.B. is Useful For

1) Retaining Wall2) Bridge Abutment3) Bridge Pier4) Highway Culverts

CONCLUSION Considering Durability, Speed, Simplicity, 30% Saving & 10% more Carpet Area. This Eco Friendly R.C.B. Construction is Particularly Suited For,

Housing, Slum Project, Transit Camp, Schools & Hospital, Hotel & Bungalow, Industrial Projects, Retaining Wall, Culverts etc.

REMARKS 1) For Affordability Architects/Engineers/Clients need to take a lot of efforts in Planning, Design, Detailing, & technology.2) The Architect / Engineer /Client must learn about Planning for the Technology first.3) Affordable structure is always green.4) Affordable does not mean cheap construction.5) By Optimum Planning we get 10% more Carpet Area.(Bonus to the Builders)
