Cost Optimisation for Sprinkler Design for an Office Fit-out

During a fit-out project, the base builder had already installed sprinkler piping and sprinklers, but a subsequent interior design change required a false ceiling to be added, increasing the ceiling height by over 800 mm. According to local fire codes (NBC Part 4 and IS 15105), additional sprinklers were needed above the ceiling void to maintain compliance. However, resizing the existing sprinkler header pipes to accommodate these additional sprinklers was not a viable option due to logistical and cost constraints.

The challenge was how to add sprinklers without disrupting the already-installed piping system. Our solution was to employ extended coverage sprinklers with a K11.2 factor. These advanced sprinklers provided the required coverage for the ceiling void without needing to resize the header pipes. While the cost of these sprinklers was slightly higher than standard options, it was a far more cost-effective solution compared to the significant expense and disruption caused by resizing the piping system.

The solution was designed, installed, tested, and successfully commissioned, ensuring full compliance with fire safety codes. The result met the client's requirements while ensuring the sprinkler system functioned optimally.

By leveraging innovation in fire safety design, we were able to deliver a cost-effective, efficient solution that adhered to safety standards, ensuring a successful outcome for both the project and the client.
