SAN FRANCISCO (KGO) -- Engineers are digging into the soil to find out why San Francisco's Millennium Tower is sinking.

The first of three holes will be bored into the bedrock and equipment will then be lowered into the holes to measure movement.

Engineers hope data will then show why the 58-story tower has sunk 16 inches and tilted two inches since it was completed in 2009.

Experts only expected it to settle four to six inches in all.

The data collected by the soil engineers could ultimately determine who's to blame and who could possibly be forced to pay millions to solve the problem.
