Kahn’s Innovations

Kahn's complex may be credited with more than one innovations :

The scale of the building

The use of as caste concrete

The use of exposed brick masonry

Frankie pile foundation

were not attempted in Bangladesh before

The use of as Caste Concrete

the concrete surface bear the imprint of the structure

no paint and plaster was used to maintain the purity of the surface

The use of exposed brick masonry

disappoint Kahn the quality of the

brick(uneven in color , developed cracks , manufacturing defects)

but introduction of dry press moulding and furnace oil firing improve the brick quality considerably

not familiar with exposed brick masonry

but the local hard-working and willing learner s grasp it quickly

as a result the flattering and the pointing were more exacting standard demanding from them

Frankie pile foundation

Foundation:

Frankie Pile foundation was used

Constructed by Swiss Boring Company

Conclusion

The most interesting things is, there is not a single column in the

entire building. Hollow columns that are parts of space enclosures have been adapted as structural supports.

One of the important considerations in designing the building was protection from the sun and rain. The structure provides a visual impression or a majestic edifice. It avoided the conventional method of placing windows in the exterior and the disadvantages of monumental composition were removed by the provision of core walls with small gaps in between. Architecturally, the complex marks a distinct departure from the rest of the modern buildings in Dhaka.

Thank you all
