AI-TCN-RiskMap: An AI-Driven Construction Management Framework

AI-TCN-RiskMap: An AI-Driven Construction Management Framework A Temporal Convolution and Risk Map–Integrated Model for Dynamic Construction Management Overview AI-TCN-RiskMap is a unified construction management framework that integrates Temporal Convolutional Networks (TCN) with a Temporal Risk Mapping Strategy (TRMS) to support time-dependent risk prediction, dynamic decision-making, and spatial–temporal safety analysis in construction projects. This framework is based on the study “An AI construction management model integrating temporal convolution and risk map construction strategies.” It provides a complete artificial-intelligence-driven pipeline for processing construction time-series data, modeling spatial site conditions, generating risk maps, and enabling intelligent strategies for schedule, cost, and safety management. The model offers interpretability, efficiency, and high adaptability across different construction scenarios, enabling more proactive and data-driven construction planning. Features ● Temporal Convolutional Risk Management Model (TCRMM) TCRMM uses multi-layer temporal convolutions to extract dynamic dependencies in construction time-series: Resource usage Schedule progress Equipment operation signals Delay indicators It implements the temporal mapping function described in Eq. (1) and the enhanced multi-layer structure in Fig. 2, enabling robust learning of long-range project dependencies. ● Hybrid Adaptive Attention Mechanism (HAAM) HAAM integrates: Multi-head temporal self-attention Channel-wise adaptive gating Normalization and residual connections This mechanism enhances temporal feature representation, improving prediction accuracy for delay risk and productivity fluctuations (Section 3.3). ● Risk Map Construction Module The model builds a time-aware and region-aware spatial risk map, using: A risk evolution formulation (Eq. 9–12) Per-region risk estimators Spatio-temporal fusion of features Iterative refinement This allows early detection of spatial hotspots, unsafe zones, or areas with abnormal operational patterns. ● Temporal Risk Mapping Strategy (TRMS) TRMS is a high-level strategy combining: Multimodal encoding of temporal + spatial inputs Region-wise risk regression Graph Propagation Layer for cross-region influence modeling Multi-step iterative refinement The method aligns with the temporal and spatial update framework illustrated in Fig. 6. ● Decision Adjustment Mechanism Using a learnable adjustment function γ(pt, rt) (Eq. 5), the model dynamically tunes decisions based on predicted risk levels, enabling more realistic schedule/cost predictions under uncertain conditions. Model Architecture The complete model integrates two subsystems: 1. TCRMM (Temporal Convolutional Risk Management Model) Processes global temporal sequences: Multi-layer temporal convolutions Hybrid adaptive attention Temporal risk estimation Risk-adjusted predictions 2. TRMS (Temporal Risk Mapping Strategy) Processes per-region features: Temporal and spatial feature encoders Region-wise risk regression Graph propagation for cross-region refinement Final construction-risk map The integrated pipeline outputs both temporal predictions (e.g., productivity, costs) and spatial risk distributions (risk maps). Datasets The framework was evaluated on four datasets—representing industrial-grade construction data—with both temporal and spatial modalities: ● Construction Project Temporal Data (CPTD) Time-series of construction progress, productivity, equipment operation, materials flow. ● Risk Assessment Maps (RAM) Spatial distributions of operational risks collected from real construction sites. ● Temporal Convolution Analysis in Construction (TCAC) Sequential operational metrics used for TCN modeling and temporal feature extraction. ● AI-Based Construction Strategy Models (AICSM) Strategy-level datasets including multi-stage decisions, resource plans, and delay annotations. These datasets enable evaluating both temporal prediction and spatial risk estimation, supporting the integrated framework proposed in the study. Evaluation The experimental evaluation covers: ● Temporal Prediction Metrics MAE RMSE R² Score MAPE ● Risk Map Metrics Risk MSE High-Risk Mitigation Rate (HRMR) Cross-region correlation consistency ● Model Efficiency Parameters, FLOPs, runtime Inference latency across CPU/GPU devices ● Baseline Comparisons Compared against: Standard TCN LSTM and GRU Transformer-based sequence models Classical safety-risk assessment models Key Findings TCRMM significantly improves temporal accuracy under long-dependency scenarios. TRMS improves spatial risk prediction, especially in cross-region correlated areas. Integrated model outperforms all baselines in both temporal prediction and spatial risk mapping. High efficiency and stable performance across all four datasets. Applications AI-TCN-RiskMap can be directly applied to: Construction schedule prediction Cost deviation estimation Safety-risk hotspot detection Resource allocation optimization Multi-region spatio-temporal decision-support Early-warning systems for construction sites Intelligent construction strategy planning The framework is suitable for smart-construction platforms, BIM-integrated systems, and digital-twin-based monitoring. Future Work According to the study’s outlook: Real-time deployment with lightweight temporal models Extension to multimodal inputs such as images, sensor data, and IoT streams Incorporation of reinforcement learning for adaptive strategy selection Large-scale construction knowledge-graph integration Cross-project transfer learning On-site robotic construction coordination These directions aim to enhance adaptability, scalability, and decision-making intelligence.
