Generalizable spatial and shape features are extracted, and surrogate models are refined through Shapley Additive Explanations (SHAP) interpretation and validation with two engineering cases. The method reduces the data acquisition complexity and reliance on experience in the design process, thereby improving automation in the design workflow. Its universality makes it broadly applicable to airbag mold ice-shell buildings in northeastern China. Applied to a representative combined shuttle-shaped ice-shell architecture, the method reveals climatic coupling relationships and dominant design parameters, including long-axis length, support length, and orientation.

This paper demonstrates and validates a scan area planning method that minimizes differences between planned and measured interpoint spacings, achieving sub-millimeter accuracy. Using this approach, point clouds of bridge pier infrastructure were collected over two years to track cracks, spalling, and reinforcement corrosion. The results revealed a 47.2% reduction in the diameter of the exposed reinforcement and a 37.1% increase in the vertical crack width, indicating significant structural deterioration.

Existing techniques like Paver Mounted Thermal Profilers and Intelligent Compaction Technologies quantify thermal non-uniformities and density differentials. In this paper, an alternative protocol was developed using unmanned aerial vehicle (UAV) assisted aerial infrared (IR) image data. A deep-learning object detection model was developed to identify the location of the paved mat and rollers in each thermal image using the YOLOv8 model. The developed framework was used for various sites visited in 2023 and 2024. Three quantification metrics for thermal segregation—Differential Range Statistic (DRS), Thermal Segregation Index (TSI), and Mat Temperature Differential Matrix (MDM)—are compared across all sites’ thermal images. A case study based on data from an experimental site is presented, and two lanes were monitored for roller movements. Compaction metrics such as the overall roller pass counts, roller speed, and insufficient roller passes based on the bottom quantile data were obtained from the developed protocol. The presented framework successfully identifies and maps the roller movements while calculating the thermal segregation and compaction metrics. When processed in the field during construction, the metrics can give near-real-time insights into the mat’s non-uniformities during paving. This developed protocol can provide actionable feedback to the contractors/agencies on the job site and help improve overall consistency in the quality of construction.</div></div>","PeriodicalId":8660,"journal":{"name":"Automation in Construction","volume":"180 ","pages":"Article 106498"},"PeriodicalIF":11.5,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145046634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
