Domes and Sky light roofing adds architectural value to the building. Building domes is in vogue right since olden times, palaces used to be built with domes made of artistic facades together with brick mortar, which is predominant especially during Moghul regime. Apart from architectural value, domes provide excellent day lighting, cutting down substantially on the power cost. Modern day sky light roofing are built entirely with glasses, supporting panels occupy least space, allowing entire light to pass through. The sight of sky from within the building provides a feeling of nature, especially creates a good work or home atmosphere. It is very eco-friendly also on the other hand.’

The Dome was designed to exhibit the looks of a Lotus flower, which had MS structure formed as the base and support for the whole work considering the strength of the material, and had consumed around 40 MT of MS material alone for the work. Aluminium frame was used in one vertical and one horizontal, which formed bed for the glasses. Safety glasses formed as the design exhibitor. Weight of a single frame with the glasses is close to 75 kilos and 69 such glasses have been used for the whole work, which is as good as 4.5MT of materials.

Adequate care had been taken to design the Aluminium support frame in terms of design and thickness. Glasses used were 23.04milimetre triple glass and was double laminated. A thicker glass was chosen for the bottom layer to support the weight of the two upper layer glasses. Enough tests had been carried out to check the strength of the glasses to bear the wind and other pressures.

The main challenge of the game was the ground clearance of the whole dome which is 30 meters. Unifab had carried out the job without using scaffolding due to work constraints. Specialized tapes and sealants have been used for the whole structure to stay as water and sound proof. The glasses have been chemically coated to make it allow minimum heat to pass through. The structure is designed in such a way that it allows the maximum light. The dome would definitely appeal for its architectural class.
