🚨 7 CONSTRUCTION MISTAKES THAT CAN INCREASE PROJECT COSTS
Construction mistakes can lead to rework, delays, disputes, and quality problems.
🔹 1. Using Outdated Drawings
This can result in work that no longer matches the approved design.
🔹 2. Poor Setting Out
Incorrect positions or levels can affect foundations, columns, walls, and services.
🔹 3. Skipping Inspections
Defects may become harder and more expensive to correct after work is covered.
🔹 4. Improper Material Storage
Moisture, contamination, or poor handling can damage materials.
🔹 5. Inadequate Documentation
Missing records can complicate approvals, progress tracking, and dispute resolution.
🔹 6. Poor Coordination
Conflicts between structural, architectural, and service installations can cause rework.
🔹 7. Unauthorized Design Changes
Changing structural or other specified work without proper review can compromise compliance and performance.
✅ How Can These Problems Be Reduced?
Use approved documents, plan inspections, communicate early, maintain records, and follow project procedures.
