Key challenges Drywall is a new concept for T2 Cities in India and most partitions and walls are done using conventional brick and masonry. Driving the acceptance of Drywall as a viable construction option and utilizing the same in bringing innovation in the Design and execution part was a key achievement. Drywall with 1 hr & 2 hr fire rating and STC of 52dB level was achieved which is inline with international standards. Wet area being highly humid environment, Gyproc FCB were used and Shaft wall with 2hr Fire rating, Core Board, FR and FRMR boards was used to overcome the challenge. On time completion was another challenge for the project which was achieved through careful planning of resources – man and material, as well as usage of DW tools for improved productivity.

Key achievements Shaft walls first of a kind in a T2 city of India. Joint working by SG team & Contractor with Developer team from Design to Completion. Complete solution offering of Gyproc System (Drywalls, ceilings) Sliding door solution using MS pipes with MR & Plain Boards for Toilet Areas Performance beyond regulatory requirement (Fire rating - 2 hrs. STC - 52dB) Optimum utilization of resources to reduce wastage & efficient site handover
