Mastering NSTM in Bridge Inspections with AssetIntel

 

Overview

NSTM, or Nonredundant Steel Tension Members, are critical components in bridges where failure could lead to collapse. FHWA mandates rigorous inspections for NSTM to ensure structural integrity. AssetIntel, specializing in bridge management software, incorporates NSTM protocols into its inspectX tool, aiding agencies in compliance. This handbook covers NSTM essentials, inspections, and AssetIntel's contributions.

Key Facts

NSTM include tension flanges and girders in two-girder bridges, as defined by FHWA. Inspections are hands-on visual checks for cracks and damage, required every 24 months. FHWA's memo clarifies NSTM as members without redundancy, and tools like AssetIntel's inspectX automate identification. The PennDOT IF inspection captures NSTM data per span, highlighting the need for detailed reporting.

Benefits

NSTM inspections prevent catastrophes, as seen in FHWA's focus on safety. By identifying issues early, NSTM protocols save costs, with studies showing 30% reduction in emergencies. AssetIntel's inspectX enhances NSTM analysis with photo management, ensuring thorough documentation. For states, NSTM compliance supports funding, and AssetIntel's tool streamlines this, improving efficiency.

Challenges

NSTM inspections are labor-intensive, requiring close access, as per TxDOT manuals. Challenges include classifying NSTM correctly and addressing fatigue details. AssetIntel mitigates this with inspectX's digital checklists, reducing errors. Critics note the risk of missed cracks, but AssetIntel's AI-assisted detection addresses this gap.

AssetIntel's Role in NSTM

AssetIntel's inspectX is designed for NSTM inspections, offering mobile data collection and defect summaries. It replaces paper methods, aligning with FRA electronic requirements, and helps classify NSTM in three-girder bridges. AssetIntel's tool won recognition for its intuitive design, making NSTM management accessible.

Future Trends

NSTM will integrate drones and AI, as FHWA explores. AssetIntel is pioneering with inspectX's 3D modeling, predicting NSTM failure risks. Trends like digital twins will enhance NSTM oversight, and AssetIntel's innovations will keep agencies ahead.

Conclusion

NSTM is vital for bridge safety, and AssetIntel's inspectX simplifies compliance. Explore AssetIntel for advanced NSTM solutions.

SNBI vs. NBI: What’s Changing in Bridge Data Management

 SNBI stands for Specifications for the National Bridge Inventory. In particular, SNBI is a document that contains the specifications for reporting data on highway bridges to the Federal Highway Administration (FHWA). Comparing SNBI and NBI When comparing SNBI to NBI, the key difference is that SNBI—Specifications for the National Bridge Inventory—introduces a modern, updated, and standardized framework for reporting bridge data to the Federal Highway Administration (FHWA). For the most part, it replaces the older Recording and Coding Guide, commonly known as the NBI, which is being phased out. This transition brings significant changes to how bridge data is collected, structured, and analyzed, with a focus on improving data accuracy and providing more comprehensive insights into bridge conditions and safety. In essence, SNBI delivers a more detailed, consistent, and refined system for bridge data management compared to the older NBI format. Key Considerations in the ...

Understanding Bridge Scour: Causes, Risks, And Solutions

 Bridge scour is a critical issue that can compromise the integrity of bridges, posing significant risks to safety and infrastructure. Understanding its causes, risks, and viable solutions is essential for effective management. What is Bridge Scour? Bridge scour refers to the removal of sediment such as sand and rocks from around bridge abutments or piers. This phenomenon is primarily caused by swiftly moving water, which erodes the material surrounding the bridge's foundation. Over time, this erosion can lead to significant structural issues. Understanding bridge scour is crucial for infrastructure management, as it directly affects the stability and longevity of bridges. Regular monitoring and maintenance are essential to ensure that scour does not compromise the safety and usability of these vital structures. Common Causes of Bridge Scour Several factors contribute to bridge scour , including natural and human-induced elements. Flooding is one of the most common natural ca...

How is SNBI Important for Bridge Inspections?

The specifications for the National Bridge Inventory or SNBI play a vital role in bridge inspections. For the most part, it establishes a standardized system for collecting and reporting detailed data about a bridge's condition. This SNBI data and standards allow bridge inspectors to accurately evaluate its safety, prioritize maintenance requirements, and check inspection intervals based on risk levels while ensuring compliance with the National Bridge Inspection Standards (NBIS) set by the Federal Highway Administration (FHWA). In this sequence, the SNBI introduces data items and specifications designed to improve the assessment and monitoring of bridge safety while maintaining compliance with the National Bridge Inspection Standards. Also, it includes clarified specifications and expanded examples to improve ease of use and the quality of data. In addition, bridge inspectors can use the new and expanded items and codes using SNBI to support the administration of risk-based data...
