Pillar Removal in Load-bearing Home

I need advice on how to properly and safely remove some pillars in my house, which could potentially be load-bearing. An architect has assessed the situation, but they did not provide concrete guidelines for the project, which is where your expertise comes in.

Ideal Skills/Experience:
• Structural engineering or architecture background
• Experience with residential structures and renovations
• Knowledge of proper safety measures and protocols

This project does not currently have the necessary materials or equipment, so any recommendations or guidance in that aspect would be immensely appreciated.
