How Long Does Core Drilling Take? 3 Key Factors That Determine the Timeline

When planning construction or renovation projects, clients often ask: “How long will core drilling take?” While timelines vary, three critical factors determine the duration:

1. Project Scale Directly Impacts Work Hours

• Small-scale tasks (e.g., 2-3 HVAC holes for homes) typically take 2-3 hours.
• Large projects (e.g., 100+ rebar holes on construction sites) may require 3-5 days.
  Pro Tip: For every 10 additional holes in standard concrete walls, expect a 30% increase in total drilling time.

2. Depth Doubles Time for Every 10cm Increase

• Common household holes (15-30cm depth): 15-30 minutes per hole.
• Specialized deep drilling (1m+ depth): 2+ hours per hole.
  Critical Note: For reinforced steel layers or complex concrete structures, use a phased drilling approach to protect equipment and boost efficiency.

3. Hidden Factors That Delay Progress

• Workspace constraints (narrow areas reduce efficiency by 40%)
• Equipment quality (professional core drills work 3x faster than handheld tools)
• Material hardness (reinforced concrete takes 50% longer than brick walls)
• Operator expertise (experienced technicians save 20% time by predicting rebar locations)

Pre-Project Checklist for Faster Completion
① Provide accurate utility line blueprints
② Conduct pre-drilling hardness tests
③ Clear 2 meters of workspace around drilling areas

Case Study: Drilling 10 holes (30cm depth) takes professional teams 2 hours less than unskilled crews. Teams using infrared positioning systems avoid damaging hidden pipes, eliminating rework delays.
