Case Study: Designing Electrical Distribution services for a high rise for N Rose Developers


High-rise buildings have difficulties not found in traditional low-rise buildings. For instance, with fires, the major cause in any building is electrical faults, which multiples in the case of high rises. This is because of longer egress distance and thus higher time taken to exit, complex evacuation strategies, challenges in accessibility to firefighters, etc.

Our Approach:

N Rose’s residential project, Heaven Plaza (Dahisar, Mumbai) is two-wings, each with a ground floor + 2 podium floors + 32 stories, for a total of 222 flats.

We foresaw that running 132/86 electrical cables in one vertical shaft across34  floors was a potential fire hazard, and so, we convinced the client to use bus ducts instead of traditional electrical cables. These are of high quality "F" class extruded epoxy insulation. We did this by providing detailed cost comparison and benefits, which helped them to take the right decision.

But that was not enough, we also had to take the approval of the electrical supply company and we worked quickly and closely with them as well as the liasoning agency to help the client get the required go ahead.

Benefits of bus ducts over traditional cables

Cables have long been a traditional means for power distribution in building services. But now, with rapid changes in technology occurring on a near daily basis, there was a requirement for an electrical system that can quickly adapt to these changes. And that is where busduct trunking comes in, as it is a modern, efficient, and cost-effective means of power distribution.

Benefits of busducts:

  1. The compact design allows for easy installation.
  2. Although the material cost of busduct trunkingis higher compared to cable, but when one considers thetotal cost of installation and labour as well as the time requirement, bus ducts provide a far superior solution for nearly the same price.
  3. The manpower requirement during the installation of busduct trunking is much lesser compared to cable installation.
  4. Metering at each floor opens up the space that would be required for the meter room at the ground level.


The Results: Bus duct trunking is a timesaving, cost-efficient, and safety enhancing alternative to electrical cabling and is now our, and our clients, preferred choice for high rises.
