I don't understand the pretend secrecy. Why not just state openly they're rebuilding or expanding the bunker? Wouldn't it be obvious from the high number of trucks coming and going from the area (even if disguised within a shed) that significant excavation is occurring, or that a significant amount of steel and concrete is then being added?

It didn't take long for people to link a growing mound of spoil on a nearby golf course (East Potomac Golf Links) to excavations occurring at the White House.[1] A few simple volume calculations, and/or truck movement counts, is all one would seemingly need to estimate the size of the new bunker.

USD$300m also doesn't buy much of anything underground, especially at top secret military bunker pricing. Look at the cost of typical rail tunneling projects (much simpler and more efficient construction) for rough comparison.
