hammers, or manual "hand-demolition" for delicate interior work. 2.
Bidding & Estimating Responsibilities Site Inspections: Walking the
site to identify "hidden" costs like shared structural walls with
neighbors or tight access that prevents large machinery use. Risk

soil contamination not shown on original blueprints. Labor
Production Rates: Calculating how many square feet a crew can clear
per day based on the structure’s complexity. Vendor Leveling:
Comparing quotes from waste haulers, landfills, and specialized
subcontractors to find the best price-to-reliability ratio. 3.
