TheUndergroundAmmunition Facility Story
The demand for space @ home…
extends to military landuse…
especially for ammunition storage
because land needs to be sterilised as safety buffers
Seletar East Ammo Depot had to go, to make way for other development

The search for a new ammo depot site started…

“Where could we find space?”
Beginning of a dream…
The answer could be right here!
“Could we go underground?”
Selecting Mandai quarry…
Selecting Mandai quarry…Excellent granite rock quality
Selecting Mandai quarry…The quarry offers easy access underground
Creating large rock caverns
Minimisinglanduse
Developing a safe and operationally efficient facility
Key challenges faced…
Addressing major technology gaps
Optimising rock cavern space
Bridging the technology gap
NATO UK ESTC US DoD
Technology review…Existing safety standards too conservative
Comprehensive technology development…
Numerical modeling
on rock cavern design and construction…
Rock engineering studies
and to validate the UAF safety design
Ground shock tests
Small-scale tests
and to validate the UAF safety design

Groundbreaking in 1999…
and the rock excavation begins
The construction…Drilling

Shotcreting
Some interesting factsThe granite is 220 million years old (Triassic Period)Granite is 6 times stronger than concrete
Some interesting factsTotal length of drill holes for blasting: 3,000 kmAmount of explosives used for rock blasting: 4,000 tons
Some interesting factsNumber of blasts: 5,560Number of rock bolts: 60,000
Our achievements
A state-of-the-art ammunition storage facility
Land savings…up to 90% compared to aboveground storage,
and 300ha land saved, equivalent to ½ of Pasir Ris New Town
New explosives storage safety standards…
incorporated into NATO safety manual
