RISMachine Learning-Based Risk Analysis for Construction Worker Safety from Ubiquitous Site Photos and Videos
Publisher: ASCE
Abstract: This paper proposes a new method for single-worker severity level prediction from already collected site images and video clips. Onsite safety observers often assess workers’ severity levels during construction activities. ...
Hydrostatic and Cyclic Pressure Testing of Small-Scale Composite Pipes and Vessels
Publisher: ASCE
Abstract: In this study, overlapped biaxial and seamless twill carbon fiber pipes and vessels were manufactured. Steel pressure vessels were repaired with flexible twill and biaxial fabric. The pipes and vessels were subjected to ...
Improved Mixed-Mode Bending Test Apparatus through Analytical Modeling and Finite-Element Optimization for Improved Characterization
Publisher: ASCE
Abstract: The compliance of the mixed-mode bending (MMB) test fixtures can influence the interlaminar fracture toughness measurements for different mixed-mode ratios in an unpredictable way. The purpose of this article is to introduce ...
Visual and Virtual Production Management System for Proactive Project Controls
Publisher: ASCE
Abstract: Current construction still suffers from significant schedule delays and budget overruns due to inefficient and retroactive project controls programs. This paper developed a visual and virtual project control system that ...
Evaluation of Multiclass Traffic Sign Detection and Classification Methods for U.S. Roadway Asset Inventory Management
Publisher: American Society of Civil Engineers
Abstract: Frequent analysis and updating the condition of traffic signs and mile markers are among the most important aspects of a highway asset management system. Today’s practices mainly involve manual data collection and analysis, ...

Cost-Estimating Model for Rubberized Asphalt Pavement Rehabilitation Projects
Publisher: American Society of Civil Engineers
Abstract: There are nearly 4,800,000 km (3,000,000 miles) of paved roads and 80,000 km (50,000 miles) of paved highways in the United States, many of which are in poor condition and approaching the end of their design life. To upgrade ...
Three-Dimensional Thermography-Based Method for Cost-Benefit Analysis of Energy Efficiency Building Envelope Retrofits
Publisher: American Society of Civil Engineers
Abstract: Recent research efforts to improve energy modeling and diagnostics for existing buildings have focused on devising methods based on digital photogrammetry or three-dimensional (3D) laser scanning and thermal imagery. Prior ...
