Key KPIs for TBM Performance

You must watch the right numbers to manage tunnel machines on long drives. KPIs show how well the tunnel boring machine works and help you make choices. When you set clear KPIs, you can keep costs low, work faster, and protect your money. The most important KPIs for TBM tunnel boring machine projects are advance rate, utilization, cutterhead wear, cost per meter, ground settlement, face pressure, alignment, and grade accuracy. These numbers help you fix problems like settlement, face instability, cutter wear, alignment mistakes, and logistics. CEGC gives tunnel machine solutions that help you reach your building goals and work better.

Advance Rate and Utilization

Advance rate tells you how fast your tunnel boring machine moves through the ground. Utilization shows how much time your TBM machine works compared to when it stops. You must track both numbers to see tunnel performance and how well your project is going. Advance rate depends on penetration rate and utilization factor. Penetration rate changes with ground type and machine strength. Utilization depends on your crew, tools, and ground. When you raise utilization, you finish projects faster and earn more money.

Watching advance rate and utilization helps you find delays and work better. You can use numbers to change your plan and keep your project moving.

Study

Findings

Flyvbjerg (2006)

Optimism bias and strategic misrepresentation cause cost overruns. Technical reasons are often overlooked.

Miranda Sarmento and Renneboog (2017)

Technical reasons are major contributors to cost overruns.

Love and Ahiaga-Dagbui (2018)

Cost underestimation impacts transport infrastructure projects. Accurate risk assessment is important.

You must use these KPIs to stop cost overruns and protect your money. CEGC’s tunnel machine solutions help you track advance rate and utilization with good data.

Cutterhead Wear and Cost per Meter

Cutterhead wear changes how well your tunnel boring machine works and how much your project costs. You must check cutterhead wear to plan repairs and control cost per meter. Studies show cutterhead wear rates change with ground type. Hard rock uses up cutters faster and needs more repairs. Coarse soils wear tools less than fine soils. Glacial ground can cause high wear and many replacements. You must use tunnel machine data to plan checks and replacements.

Watching cutterhead wear lets you find strange patterns early. Real-time data and prediction models help you plan repairs and stop downtime. You protect your cutterhead and save money.

When you track cutterhead wear and cost per meter, you make your tunnel work better and faster. CEGC’s TBM tunnel boring machine and Microtunnelling Machine solutions give repair-focused plans and cutterhead designs you can change.

Ground Settlement and Face Pressure

Ground settlement and face pressure are important KPIs for tunnel building in cities. You must keep settlement safe to stop surface damage and claims. International rules set the highest allowed subsidence at 30 mm. Many projects aim for settlements between 5 and 13 mm and volume loss between 0.3% and 0.63%. You must check face pressure to stop tunnel collapse or blow-out.

Parameter

Limit

Maximum Allowable Subsidence

30 mm

  • Maximum settlements range from 5 to 13 mm.

  • Volume loss stays between 0.3% and 0.63%.

Face stability checks are needed for safety. Low face pressure can make soil fall in. High face pressure can cause blow-out. Careful face pressure keeps your tunnel safe.

You must use these KPIs to protect your project and money. CEGC’s tunnel machine solutions have closed-mode face support and ground protection systems for safe building.

Alignment and Grade Accuracy

Alignment and grade accuracy are important KPIs for tunnel building. You must keep your tunnel boring machine on the right path and grade to stop extra work and utility problems. Small steering mistakes can grow during long drives and cause project failures. You must use guidance systems and real-time data to stay accurate. CEGC’s tunnel machine solutions have strong structures and guidance system integration for good performance.

Watching alignment and grade accuracy helps you finish your project well. You work faster, lower risk, and protect your money. When you use clear KPIs, you make better choices and reach your building goals.

KPI Tracking and Improvement Strategies

KPI Tracking and Improvement Strategies

Defining and Measuring KPIs

You should set clear KPIs before starting a tunnel project. KPIs help you see how well your tunnel boring machine works. Digital tools can track these numbers for you. Building Information Modelling shows how your tunnel affects the world, money, and people. You need to pick sustainability KPIs when you plan and watch them as you build. You can use Project Information Models first, then switch to Asset Information Models later. This helps you run and fix the tunnel after it is built. Using materials again and saving energy lowers your tunnel’s carbon footprint. Digital tools give you facts so you can make good choices at every step.

  • Use BIM to link all parts of your tunnel project.

  • Pick KPIs for sustainability when you plan.

  • Watch KPIs live while you build.

  • Change from PIM to AIM for long-term tunnel care.

  • Try to reuse materials and save energy.

KPIs help guide your tunnel project from start to finish. You can use them to do better work and protect your money.

Data Collection and Monitoring

You need to collect data and watch your tunnel project to keep things on track. Automated systems give you real-time information about tunnel boring machine performance. Real-time jacking insights let you see important numbers right away. Automated reports save time and keep everyone in the loop. Monitoring and alarming systems mix ground data with tunnel machine data for a full picture. These tools help you spot problems early and fix them fast.

  • Real-time jacking insights show how your tunnel is going.

  • Automated reports keep your team in the know.

  • Monitoring and alarming systems make things safer and better.

Automated data collection makes tunnel building safer and more steady. You can use these tools to keep your project and money safe.

Benchmarking and Performance Analysis

You need to compare your tunnel project to industry standards to see how you are doing. Benchmarking helps you find ways to build better and protect your money. You can use tables to track tunnelling costs, production rates, and asset costs. Collect old data about cost, schedule, and performance. Use standard templates to make data collection easy and the same every time.
