PermitGPT: A Unified Generative-AI Pipeline for Construction Hazard Forecasting, Permit Prediction, and Community Impact

PermitGPT is a generative‑AI framework that transforms unstructured construction permit descriptions into structured outputs for safety hazard identification, permit requirement specification, and community impact assessment. It aligns data from the NYC Department of Buildings, OSHA, and NYC 311 to create 90,000 prompt‑response pairs, fine‑tunes three open‑weight language models, and evaluates them on 2,833 test cases, reporting complementary performance across inference speed, lexical overlap, and semantic alignment. The study presents an initial AI‑assisted approach to construction governance and outlines future evaluation and validation directions.

Towards reliable multimodal disaster severity assessment through preference optimization and explainable vision-language reasoning

The paper introduces a two‑stage training framework that combines Supervised Fine‑Tuning (SFT) and Direct Preference Optimization (DPO) to improve multimodal disaster severity assessment. It creates two datasets—ReasoningSet for validated rationales and PreferenceSet for paired rationales—using a single Human‑in‑the‑Loop workflow. Experiments on InternVL‑3‑8B and LLaVA‑1.5‑7B show that SFT boosts classification accuracy and Macro‑F1, while DPO further enhances interpretability and alignment with human judgment.

POTracker: Optimizing Large Language Models for Standard-Compliant Power Outage Report Generation

arXiv:2606. 23533v2 Announce Type: replace Abstract: Recent large language models (LLMs) are good at general text generation, but it is still hard to use them for domain-specific data generation because the output must follow strict formatting and structural rules.

Grounded Normative Rule Generation with Structured Search

The paper introduces Grounded Normative Rule Generation (GNRS) and a new framework called GNRS-Search that uses Markov Chain Monte Carlo sampling to optimize a discrete And-Or Graph for rule synthesis. By separating operational feasibility from prose generation, the method localizes rule failures before final text creation. Evaluations on GNRS-Bench and RealCharter-Bench show significant improvements in rubric quality and executable metrics, demonstrating that the gains come from robust operational logic rather than stylistic tuning.

ConstructCIE: A Dataset for Extracting Causal Information from Construction Accident Narratives

ConstructCIE is a manually annotated dataset designed for extracting causal information from OSHA construction accident reports. It employs a hierarchical schema that categorizes accident types, causal factors, sub‑causal factors, and the supporting evidence spans. Experiments with supervised sequence taggers and instruction‑tuned large language models show strong performance on accident‑type prediction and broad causal recovery, yet precise span‑level extraction remains challenging, highlighting the need for better domain grounding and evidence extraction.
