Old light fittings were replaced with LED lamps.
DBs and control panels were replaced to ensure
adherence to current standards and to improve layout
and ensure general conformance and maintainability.
The old CO 2 gas suppression system in Block C
(protecting the main genset plant room and the diesel
day tank room) was replaced with an environmentally
friendly and safe Novec system from 3M (Sevo
Systems), with all components complying with SANS,
UL, and ISO standards.
General fire detection and protection were improved.
More breathing sets and suits were provided, fire
escapes were added, and the fire detection system was
upgraded to accommodate the new plant-room layout.
A walkway was installed on the roof of Block A to
make access to scientific instruments easier and safer.
Wind tunnel tests were conducted to ensure that the
walkway would not have negative effects such as
dumping of snow on the leeward side.
A new safety net was installed at the cliff edge.
The entire building and systems were modelled in Revit.
