How AI and Machine Learning are transforming construction scheduling: A Case Study of Diaphragm Wall Duration Prediction in Singapore

October 2, 2025


🏗️ Raising Awareness: How AI and Machine Learning Are Transforming Construction Scheduling

Why Construction Needs a Smarter Forecasting Approach

Construction scheduling has long relied on deterministic methods—estimating durations based on fixed parameters like length, width, depth, or soil type. While these inputs offer a baseline, they often fail to reflect the complexity of real-world conditions. Factors such as panel geometry, site constraints, and sequencing interact in ways that traditional models can’t capture.

In an industry where delays can cascade into cost overruns and stakeholder friction, the need for data-driven, adaptive forecasting is more urgent than ever.


Applying Machine Learning to Real Construction Data

To demonstrate the potential of AI, I trained machine learning models using 1,095 actual records from diaphragm wall (Dwall) construction activities. Each record included the actual duration taken to complete a panel installation—making it a grounded and outcome-driven dataset.

The features used for prediction included:

  • Panel Length, Width, Thickness
  • Soil Type (numerically classified)
  • Substructure Length
  • Crew Size and Machine Type (constant across records)

Using Azure AutoML, I ran a regression experiment that tested multiple algorithms—including LightGBM, MaxAbsScaler + LightGBM, Boosted Decision Tree Regression, ElasticNet, and Extreme Random Trees—with ensemble stacking and hyperparameter tuning. The best-performing model was a MaxAbsScaler + LightGBM. A comparison of the best 2 models and the evaluation metrics as shown:

MetricBoosted Decision Tree RegressionMaxAbsScaler + LightGBMInterpretation
R² Score~0.150.262LightGBM explains 26.2% of the variance—significantly better at capturing patterns.
MAE (Mean Absolute Error)~1.831.89Both models have low average error; difference is negligible.
RMSE (Root Mean Squared Error)~2.742.92Slightly higher error for LightGBM, but acceptable given its better R².
Median Absolute Error~1.301.35Half of predictions are within ~1.35 units—both models are consistent.
MAPE (Mean Absolute Percentage Error)~31%32.68%LightGBM is off by ~33% on average—reasonable for construction forecasting.
Explained Variance~0.150.266LightGBM captures more variability in actual durations.
Spearman Correlation~0.380.443Stronger monotonic relationship with LightGBM—better for sequencing decisions.

Even with operational constants like crew size and machine type, the model successfully learned from geometric and geotechnical features. Panel Thickness and Soil Type emerged as key drivers of installation duration—highlighted through permutation-based feature importance.


What This Means for the Industry

Machine learning offers a leap forward in construction scheduling by:

  • Improving accuracy: Forecast durations based on real patterns, not assumptions
  • Enhancing transparency: Justify estimates with explainable models
  • Scaling insights: Apply models across different sites and configurations

For project managers, this means better resource planning and reduced risk buffers. For engineers, it opens the door to integrating predictive analytics into everyday workflows. And for stakeholders, it builds confidence in schedules grounded in data—not guesswork.


🤝 Collaborative Invitation

As a project manager and project control specialist with extensive experience in construction planning and execution, I believe the adoption of AI and machine learning in scheduling is not just a technical upgrade—it’s a strategic evolution.

I welcome collaboration with companies, developers, and industry professionals who are exploring how machine learning can enhance the prediction of project completion and improve scheduling accuracy. Whether you’re considering pilot studies, data integration, or full-scale deployment, I’m open to sharing insights and working together to build smarter, more resilient construction workflows.
