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

Non-Destructive Testing for Structural Condition Assessment

Non-Destructive Testing for Structural Condition Assessment

Structural Condition Assessment usually refers to the process of collecting observations and data about the existing condition of the structure through systematic and scientific methods. According to the Professional Engineers Ontario Guideline for “Structural Condition Assessment of Existing Buildings and Designated Structures” (PEO, Nov 2016), structural condition assessment are within the practice of professional engineering. This primarily fall in two categories: Preliminary assessment Detailed condition assessment Depending on the objectives… Read More »Non-Destructive Testing for Structural Condition Assessment

In-Place Methods to Estimate Concrete Strength Using Rebound Hammer

Estimate Concrete Strength Using Rebound Hammer

In-Place Test methods to estimate concrete strength has been extremely popular among engineers and inspectors involved in the field of structure inspection, evaluation and condition assessment. Various non-destructive methods have been developed by different researchers over the past few decades to assess in-place strength of concrete. The rebound hammer, developed by Ernst Schmidt, provides an inexpensive and quick method for nondestructive testing and evaluation of the hardness of concrete. In… Read More »Estimate Concrete Strength Using Rebound Hammer

the future of bridge inspection

The Future of Bridge Inspection

The Canadian Highway Bridge Design Code (S6-14, 2014) considers a service life of 75 years for newly constructed bridge. What does this mean in engineering terms? It means that the bridges of the future should have satisfactory performance, both durability and structural, during the proposed life-cycle. This can be quite challenging when we look closely; the environment and environmental loading (i.e. snow, freeze and thaw cycles, corrosion, earthquakes, etc.) can… Read More »The Future of Bridge Inspection

Practical Considerations in Pile Testing

  • by

Pile Integrity Testing (PIT) is a non-destructive testing method for evaluating the unknown length and integrity of piles and deep foundations. The basic concept behind the technique is determining the velocity (required) and force (optional) response of pile induced by an impact device (normally, a handheld hammer). Pile Integrity Testing works best for long structural component such as driven concrete piles, cast-in place concrete piles, concrete filled steel pipe piles, timber piles,… Read More »Practical Considerations in Pile Testing

Applications and Limitations of Pile Integrity Test

Applications and Limitations of Pile Integrity Test

  • by

Pile Integrity Test can be used to determine the integrity of piles. The method works best for long structural component such as driven concrete piles, cast-in place concrete piles, concrete filled steel pipe piles, timber piles, structural columns. The method works based on measuring and analyzing the velocity (required) and force (optional) response of pile. A hammer (regular or instrumented) is used to impact the pile surface and induce acoustic waves… Read More »Applications and Limitations of Pile Integrity Test

Reuse of existing piles and deep foundations

Reuse of Existing Piles – How NDT Can Help

Safety, reliability and satisfactory performance of structures require a well-planned maintenance program, as well as remedial actions in short and mid-term. Existing structures that are designed in accordance with older design codes or were built by older construction practices may need to be extensively repaired, rehabilitated, or replaced within the next few years. The remedial actions may include structural and/or foundation upgrade or replacement. Reuse of existing piles and foundations is… Read More »Reuse of Existing Piles – How NDT Can Help

Non-Destructive Evaluation of Unknown Foundations

Non-destructive evaluation of unknown foundations and piles has gained interest among engineers and researcher over the past few years. Latest research show the effectiveness of these methods in investigating the depth and quality of existing piles, as well as in the quality assurance of new construction. Piles are structural members made of timber, steel, or concrete. Piles are used to transfer the loads of a heavy superstructure (bridge, high rise… Read More »Non-Destructive Evaluation of Unknown Foundations
