It has been attempted in the past and the recent endeavour by an architect in Mysuru has further improved the earlier ideas.

28bgp-greensens_26_2637392eWe are now living in an age of innovation where the old order is continuously being replaced by the new. Should this sound like a great time, let us remind ourselves the fact that such an age will also be a time of both gains and losses. Large number of time-tested ideas like courtyards and hot air ventilation are rarely found today, despite them being valid even now. However, there is hope in many other items of works, which are still popular, despite being practised in an improvised version.

In many ways, improvisation is also a part of innovation, yet by retaining the original at a conceptual mode, we see our past flowing into the present. The change is more gradual when we effect better finished and more efficiently managed products and services. Many such improvisations happen during construction at site mostly thought out by the project team; as such do not get documented for wider dissemination. Lack of professional efforts to collate the best practices within us compounds this lacuna, hence the potential to upgrade our methods and skill sets gets largely lost.

Lintels can be a good case to illustrate. In the past, the support above any opening like a door, called as lintel, was achieved by stone, wood, door frame itself or totally avoided by having an arch. With RCC lintels being the order of the day even in small villages now, it is time to relook at it.


One option is to revive the past with stone lintels and another could be to avoid them except where needed absolutely, choosing to do cut lintels. In many cases due to site conditions or earthquake considerations, we may need them to run all around the walls at 7 ft. height.

roviding the necessary shuttering, casting, curing and de-shuttering means slowing down the project; letting cement water flow down defacing the wall below and face tricky situations in some cases on the external side of the wall. If the lintel could be precast on ground to be placed on wall top, the task gets much easier.

Each piece has to be cast to the exact wall length needed; junctions between two pieces has be resolved to provide continuity; placement of all the pieces needs to be secure and aligned.

What if we can go one step further in improvising the idea? Let us pre-cast the U-shaped lintel channels on ground, cut them to fit wall lengths, lift and place them on wall tops securely with rich mortar base.

The channel itself acts like the lintel; hence reinforcement rods can be considered only where required. Once the channels are filled with the required mortar mix and cured, further wall work can resume without much delay.

Pre-casting the lintel has been attempted in the past and the recent attempts by architect Rajesh Jain in Mysuru has improved the earlier ideas. There will be further scope too, as long as we wish to better a product.
