Hospital’s central court yard of 10 m x 19 m size has been covered by a single layer lamellar roof system. Cladding for the roof is multi walled polycarbonate sheets.

Rectangular closed tubes are used as roof vault members. Special nodal elements were designed and fabricated to achieve members in one plane for members intersecting at a node.

A perfect hinge connection has been used at the intersection of the vault roof and the supporting structure.
