Generational Shift in Construction using Inter-Locking Bricks in a PPP based model

Vaibhav Kukreja, Madhur Kukreja


Rapid urbanization is considered as the most significant activity of this generation. As urban population crosses about half the total population, it becomes imperative to analyse whether we are prepared to meet the challenges posed by urban migration.

More than 20 percent of India’s urban population live in slums. Popular cities such as Mumbai has more than half of its population living in slums or other unauthorized tenements. Unless suitable technologies and policies aimed at providing affordable housing are adopted, the situation might even get worse. The current approaches are too rigid, costly with little community participation. These approaches have only a minimal impact and we continue to wait for game changer ideas to solve this challenge at a larger scale.

Using inter-locking bricks can solve the issue to a larger extent. Uniqueness of this technology lies in bringing radical improvements in the construction parameters—time, cost, ease of construction and flexibility in design. These specially designed bricks have protruding tops and depressions at bottom. Stacking them on one-another creates locking mechanisms. This technology, coupled with vernacular building material, has the potential to bring down cost of construction. The material of the brick can vary with the local conditions of availability and temperature.

Whole project can be modelled on the lines of Public Private Partnership (PPP), wherein Government provides the land by regularising existing settlements and other municipal services, while private players can, through CSR initiatives, fund the material and logistics cost, making the whole model environmentally sustainable. About 40-50 percent cost reduction can be achieved through this method. This research paper substantiates its findings by using a slum in Bhopal as a case study.
