Built to perfection

The new Nivea plant in Gujarat, with its accurate design specifications, has been built to perfection.

Beiersdorf AG, parent company of Nivea and one of the world´s leading international skin care companies, has over 130 years of experience in skin care. The company, with one of the world´s most modern skin research centres, offers innovative and high-quality cosmetic products. It wanted to set up its first manufacturing plant in India for a range of creams and lotions at Gujarat Industrial Development Corporation at Sanand. Nivea awarded the contract for design, manufacture, supply and erection of the 10,397 sq m industrial building to Tata BlueScope Building Solutions with performance-based bonus. The project, scheduled in the monsoon season, was to be completed in mutually agreed time frame.

Key project requirements
The major requirements of the projects included

  • 10 years leak-proof warranty.
  • 48.0 clear span to facilitate process requirements.
  • On-time project completion without compromising quality, safety and leak-proof performance.

Challenges
The project faced several challenges such as:

  • Ensuring a long term leak-proof roof performance with 80 number of openings in the roof for fixing of turbo vents and with skylights in 4 per cent of the total area.
  • Completion of the project in mutually agreed schedule during the monsoon season.

Leak-proof Roof System
Considering all the project requirements, the project team proposed a BUTLER® Building System with MR-24® Roof system - the best leakproof solution available for critical industrial applications.

Side Laps

  • Involves 3600 double lock seaming of side lap. 180 degree is seamed at site by Roof Runner® to achieve a greater leak-proof assurance.
  • Pre-punched purlins for fixing of roof clips helps in better alignment of side laps, faster installation and superior aesthetics.

Roof Clip

  • 32.5 mm clip movement of in both directions abolishes roof expansion joint till 250 ft of panel length.
  • Centering arrangement in Roof Clip ensures thermal movement in both directions.
  • Triangular bar with thin cadmium coating in clip assembly helps in reducing friction and provides greater sensitivity to thermal movement.

End Lap Design

  • Pre-punched panels ensures tighter and neater end laps.
  • Splice position exactly above purlin ensures that the joint does not weaken due to foot traffic.
  • Only two MR-24® panels are joined at end laps and staggered end lap splices helps in reducing chances of leakages.

Roof Curbs

  • Internal flange design of curb conceals fasteners with curb that helps in eliminating the possibility of leaks.
  • Diverter flashings at Roof Curbs prevents ponding on the high side of the roof curbs.
  • Curbs are secured to roof sheet and not to purlins, this ensures uninhibited thermal movement of entire roof system.
