Sinking Building_Location: New York, New York
Building Description: 300-foot cathedral under construction
Problem: Construction is halted because soil is too soft
Task: Decide whether it's possible to continue building the cathedral
Budget: Less than $1 million


Special Notes: "What a mess! The soil is soft as clay in some places and rock-hard in others. If you build a cathedral here, the structure will sink into the earth and tilt like the Leaning Tower of Pisa!"
-- Geotechnical Engineer

Is it possible to continue building the cathedral? Decide which option makes the most sense for this situation.

 Don't build the cathedral here. It's too unsafe.    Inject a chemical glue to make the soil hard    Dig deeper, until you reach stable, solid ground
Stop building the cathedral.
