Take a trip down to the SG Defence Exhibition at Marina Bay Sands and you will see this beautiful map of Singapore’s soil/rock composition. Essentially the darker the colour, the harder the rock is. Taking that into account, the Defence Community has studied and developed the Underground Ammunition Facility in Mandai. See below;
With the years gained in digging through granite, protecting and building the facility against internal explosions, we can safely say the defence technology community has know a few knowledge in building tough underground facilities. Now, these knowledge can be used vice versa, in helping the Singapore Armed Forces build safer and stronger underground operational facilities against external threats and out of public eyes.
The UAF is part of the SG Defence Exhibition now on at Marina Bay Sands, till 8 Nov 2016. Admission is free.
