Fixing things on time helps your tunnel boring machine work well. This means the machine does not stop often and stays safe from harm.
-
Fixing problems quickly keeps the project on track and safe. Fast fixes help you finish on time and make clients happy.
Yaw correction costs less than rework on TBM machine jobs
Labor and Material Savings
You notice the savings when you fix problems early. Yaw correction costs less than rework on TBM machine jobs because you do not waste labor or materials. If you correct the yaw of your tunnel boring machine right away, your crew keeps working forward. You do not have to remove and rebuild tunnel parts. You save concrete segments, steel reinforcements, and other supplies.
Let’s check a simple comparison:

Early correction uses fewer resources. Your project stays on schedule. You do not pay for extra shifts or overtime. You do not need to buy replacement materials. CEGC’s teams have seen these savings in tunnel machine projects in cities like Riyadh and Jakarta.
Tip: If you watch your TBM machine’s yaw and fix it quickly, you protect your money and your timeline.
Equipment and Downtime Reduction
You also keep your equipment safe. Yaw correction costs less than rework on TBM machine jobs because you cut downtime. If you fix the yaw early, your tunnel boring machine keeps moving. You do not have to stop the machine for long. You avoid damage from too many starts and stops.
Here is what happens if you wait to fix the problem:
-
You must stop the TBM machine.
-
You might hurt the cutterhead and drive systems.
-
You spend more time on repairs and checks.
-
You lose important production hours.
CEGC’s experience shows that fixing yaw early keeps machines running well. You use less fuel and fewer spare parts. You avoid expensive breakdowns. You finish your tunnel faster and safer.
Note: Every hour your TBM machine is not working, your project loses money. Early yaw correction keeps your tunnel boring machine moving and your team busy.
Yaw correction costs less than rework on TBM machine jobs in every way. You save labor, materials, equipment, and time. CEGC helps you with advanced monitoring tools and expert advice so you can make the right corrections at the right time.
Time & Risk in TBM Operations
Project Delays from Rework
You face real risks when you delay yaw correction on your tunnel boring machine. Rework often leads to project delays and higher costs. Many problems can cause these setbacks. Some of the most common reasons include:
-
Design errors. Inaccurate or incomplete drawings force you to stop and redo work.
-
Quality issues. Poor workmanship or bad materials mean you must fix mistakes before moving forward.
-
Utility conflicts. Hidden pipes or cables can block your path and require changes to your plan.
Each time you stop for rework, you lose valuable days. Your team must wait while you solve the problem. You may need to order new materials or bring in extra workers. These delays can push your project past its deadline and increase your budget.
Risk Reduction with Early Correction
You can avoid many risks by correcting yaw early. When you act fast, you keep your tunnel boring machine on track. Early yaw correction helps you stick to your schedule and finish your tunnel on time. You also reduce the chance of making more mistakes later.
Small errors can grow if you do not fix them right away. One small misalignment can lead to bigger problems down the line. By correcting yaw early, you prevent these issues from compounding. Your project stays safe, and your team works with confidence.
Yaw correction costs less than rework on TBM machine jobs because you control your risks and protect your timeline. You build trust with your clients and deliver better results.
Real-World Impact
Example: Savings from Yaw Correction
You save a lot when you fix yaw early. Picture working on a metro tunnel in Southeast Asia. Your team finds a small misalignment in the tunnel boring machine. You act quickly and fix the yaw. You do not stop the machine for long. You do not remove tunnel segments or call extra workers. The project stays on schedule. You finish the tunnel on time and save money.
Acting fast keeps your schedule safe and saves money. Your crew stays busy, and your tunnel machine keeps moving.
