Geo-Structural Instrumentation and Monitoring: Safeguarding Structures and Enhancing Performance
Geo-structural instrumentation and monitoring play a crucial role in ensuring the integrity, safety, and performance of various structures subjected to geotechnical and environmental forces. This presentation aims to provide an in-depth understanding of the significance of geo-structural instrumentation and monitoring and its impact on the design, construction, and maintenance of structures.
The discussion explores a range of instruments utilized for geo-structural monitoring, including inclinometers, strain gauges, settlement plates, extensometers, and load cells. These instruments enable the measurement and analysis of critical parameters, providing valuable insights into the behavior and performance of structures under varying loads, ground conditions, and environmental influences.
Moreover, the presentation delves into the benefits of geo-structural monitoring. By continuously monitoring and analyzing structural response and ground behavior, project stakeholders can detect potential issues in real-time, evaluate design assumptions, optimize structural performance, and implement timely remedial measures. This proactive approach significantly reduces the risk of structural failures, ensures safety, and minimizes maintenance costs throughout the structure's lifespan.
Case studies will be presented to illustrate the practical applications of geo-structural instrumentation and monitoring in various types of structures, including bridges, tunnels, high-rise buildings, and retaining walls. These case studies highlight the successful identification of structural deficiencies, the evaluation of design assumptions, and the implementation of effective maintenance strategies, resulting in improved structural performance and enhanced public safety.

Innovative Approaches to Bridge Inspection, Load Rating and Repair
Most states have a comprehensive bridge management program that requires all bridges to be routinely inspected by a qualified team and that findings are properly reported. The CT Department of Transportation (CTDOT) Bridge Inspection Program will be discussed as well as the requirements to qualify for Project Manager, Deputy Project Manager, QA/QC Engineer, Team Leader, Assistant Team Leader, etc. During a bridge inspection, there may be findings which cause concern such as changes in existing structural conditions from deterioration, cracks, or vehicle impact damage. Inspection teams are tasked with clearly recording field data with enough information for load rating engineers to model and evaluate the deficiencies. Specialized software is used to model and determine the bridges current load carrying capacity. These results will help to allocate resources for bridge rehabilitation, repair, or replacement. Examples of bridges to be discussed include the Whitestone Suspension Bridge, the Jamestown-Verrazano Post-Tensioned Segmental Bridge, and a RI bridge that was closed due to inspection findings and subsequently repaired.

Enhancing Structure Inspection with Advanced Technology
AI Engineers, Inc. (AIE) has been performing conventional structure inspection for over 30 years. For the past 7 years, innovative technology like unmanned aerial systems (UAS/drones), light detection and ranging (LiDAR) scanning, and wireless monitoring sensors have been utilized on evaluation projects to supplement our inspection team’s efforts. AIE has now formed strategic partnerships to bring together engineering, computer vision, deep learning, and artificial intelligence (AI) to safely monitor infrastructure assets, minimize the risk of failure, prioritize repairs, and optimize infrastructure spending. These insights are delivered in the form of annotated 3D models, orthomosaic images, summary tables, and granular reporting. The process is also repeatable, allowing changes in the structure to be tracked over time. In addition, the data is ready to be leveraged for the industry’s push towards digital delivery by creating detailed bridge information models (BrIM), building information models (BIM), and other digital asset management resources.

Division Street Bridge Demolition – Rural Challenges
In September 2019, the Division Street bridge over the scenic Housatonic River in Great Barrington, MA was closed, much to the dismay of local residents and business owners, in response to safety concerns. Shortly before the closure, the Massachusetts Department of Transportation delivered a bridge rating report to the Town of Great Barrington, and the findings were clear…zero rating of multiple roadway framing members. Over the next few years, funding was pursued and a bid package was developed to resolve the closure. A contract was awarded in the spring of 2022 to replace the existing superstructure with a temporary modular truss system. The first challenge, of course, was to devise the removal of the existing 138’-0” truss span, without the typical benefit of temporary supports along its length. One of the contract’s key restrictions was “No work will be permitted in the water between the delineated bank lines”. An innovative Construction Engineering approach was conceived: deploy large scale bridge demolition means and methods in a rural environment.
