The main reasons behind cracking is discussed. A systematic approach for evaluating the current condition of the beam is presented. Certain features of concrete cracks, such as the crack width and crack depth are… Read More »Non-Destructive Evaluation of Cracking in Concrete Beams

Monitoring of Ground-Borne Vibrations from Construction and Demolition

Ground-Borne Vibration can be a serious concern for any building or structure within or adjacent to a construction zone. These structures may be potentially impacted by vibrations emanating from construction activities such as demolition, compaction, excavation, blasting, pile-driving, and operating heavy earth-moving equipment. In extreme cases, the vibration can cause damage to adjacent buildings and create discomfort and annoyance for building occupants. This is a particular concern to heritage structures… Read More »Monitoring of Ground-Borne Vibrations from Construction and Demolition

Diagnostic Load Testing of Bridges

Bridge Diagnostic Load Testing

Load testing is a common practice among bridge engineers for the assessment of bridge safety and serviceability. Diagnostic load testing is one type of load test methods that can be used either as a means for estimating the load carrying capacity of an in-service bridge or as an acceptance test before the bridge is put into service [Olaszek et al, 2014]. This article provides a quick review to Diagnostic Load… Read More »Bridge Diagnostic Load Testing

On Site Evaluation of Concrete Strength - FPrimeC Solutions

5 Methods for On-Site Evaluation of Concrete Strength

On-site Evaluation of Concrete Strength is a main challenge in the condition assessment of existing infrastructure, or the quality control of new construction. Owners, maintenance managers of such existing concrete structures normally prefer non-destructive and non-intrusive methods to avoid further damage to an already struggling structure. In construction projects, switching to non-destructive means less intervention, shorter down-times, and saving money. However, all parties agree that the strength of concrete is… Read More »5 Methods for On-Site Evaluation of Concrete Strength

Smart Sensors for Structural Health Monitoring

Sensors for Structural Health Monitoring

With recent advancements in Sensor technology, Structural Health Monitoring (SHM) systems have been developed and implemented in various civil structures such as bridges, buildings, tunnels, power plants, and dams. Many advanced types of sensors, from wired to wireless sensors, have been developed to continuously monitor structural condition through real-time data collection. However, there are still a remarkable number of questions associated with the use of SHM sensors. For designing a… Read More »Sensors for Structural Health Monitoring

Non-destructive testing of concrete foundations

Non-destructive Testing of Concrete Foundations

  • by

Concrete foundations are a key component in every major structure. They provide the much-needed stability to structural systems, and/or heavy industrial equipment they are supporting. The foundation system and type depend heavily on the superstructure load, and soil properties. As a result, concrete foundations may appear in different shapes, and sizes. In general, foundations can be grouped as: Shallow foundations Deep foundations In reality, engineers might face a broad spectrum… Read More »Non-destructive Testing of Concrete Foundations

Cold Joints in Concrete Beams

Non-Destructive Evaluation of Cold Joints in Concrete

  • by

This technical note briefly discusses non-destructive evaluation of cold joints in concrete structures. We will review how structural engineers and quality control laboratories can utilize NDT methods to assess the quality and integrity of concrete on or around the cold joint. What is Cold Joint in Concrete? Cold joints in concrete primarily happen when there is a significant delay between different concrete pours. For examples, if there is an interruption… Read More »Non-Destructive Evaluation of Cold Joints in Concrete

Non-Destructive Testing of Wind Turbine Foundation

Non-Destructive Testing of Wind Turbine Foundation

Over the past decade, Canada has heavily invested in wind energy, increasing its annual capacity from nearly 2,000 MW in 2008, to 13,000 MW in 2019. That is enough to power approximately 3.3 million homes – 6% of our country’s electricity demand (Canadian Wind Energy Association, 2019). There are 299 wind farms operating from coast to coast, including projects in two of the three northern territories. While the quality control,… Read More »Non-Destructive Testing of Wind Turbine Foundation

Non-Destructive Testing for Detailed Bridge Condition Survey

Non-Destructive Testing for Detailed Bridge Condition Survey

The following article is a quick review of the most cost-effective and easy to implement non-destructive testing for detailed bridge condition survey. We were recently involved in a detailed bridge deck condition survey in Perth, Ontario. The main objective was to inspect and evaluate the existing condition of the bridge deck, identify surface and subsurface defects, and evaluate the corrosion activity. As one might expect, the scope of project leaves… Read More »Non-Destructive Testing for Detailed Bridge Condition Survey
