Herculean task: Upgrading work being carried out on
the Komtar Geodesic Dome
KOMTAR’s iconic Dewan Tunku Geodesic Dome is undergoing a RM1.3mil major facelift, 25 years after it was built.

Komtar assemblyman Ng Wei Aik said the project is being carried out by the Penang Development Corporation (PDC) which manages the dome.

He said the upgrading works which started a month ago was scheduled to be completed in August.Ng said PDC appointed a contractor to carry out water proofing works on the dome.

“There were at least 10 spots leaking on the dome which were causing inconvenience to organisers during events, especially on rainy days.

“The contractor is using polyurea, a material used for roof coating, which can be applied to practically any surface as it can be moulded into any shape and size,” he said.

He also said the material fills gaps and holes and completely covers surfaces to prevent leakage.

Ng said by using polyurea, the contractor had given assurance of a 10-year warranty.

“The dome will definitely be restored to its former glory once the upgrading works are over,” he said.

The dome is a partial-spherical structure based on a pattern of circles called geodesics which intersect to form triangular elements.

These triangular elements spread the stress across the entire structure. It is based on a concept studied, developed and popularised by R. Buckminster Fuller.
