Design almost finalized, decrease uncertainty
Contingency: 10% → $30 million - Building & Tunneling – $500 million
Excessive technical complexity and subsurface unknowns
Contingency: 12% → $60 million - Methods Set up & Commissioning – $100 million
Threat of apparatus delays or integration challenges
Contingency: 10% → $10 million
Complete Building Contingency: $150 million
