Risks & Staging Best Practices

Consequences of Not Staging Spares

If you do not keep spares ready for your tunnel boring machines, you face big problems. Your project can stop for hours if you do not plan ahead. Every hour your machine is down can cost $260,000. If your tunnel stops for four hours, you lose more than $1 million. You might also have to pay fines and extra fees. The Bertha project was delayed for two years and got a $57.2 million fine because parts were missing. Unplanned downtime does not just cost money. It also puts your team in danger. When you hurry to fix things, accidents are more likely. If you use old parts for too long, you can break your machines. Broken machines can make the tunnel unsafe. You need to plan ahead so these things do not happen.

• Unplanned downtime makes your project cost more and take longer.

• Broken machines can make the tunnel dangerous.

• You could get fined or have to pay penalties.

• Your team is at risk when they fix things in a hurry.

• The tunnel work slows down and you lose control of your schedule.

Keep your spares organized so you can find them fast. Teach your team to check and change parts on a set schedule. Use a checklist to keep track of what you use and what you need to order.

Tip: Keep your most-used spares near the tunnel entrance. This saves time when you need to fix something and keeps your tunnel boring machines working.

You should also match your spare parts plan with your work and delivery plans. This helps you get new parts before you run out. If you wait too long to order, your machines might stop working.

Real-World Scenarios & Technical Solutions

Case Studies in Spare Staging
