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 Read more about 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.

In-Place Methods to Estimate Concrete Strength Using Rebound Hammer

Estimate Concrete Strength Using Rebound Hammer

[DISPLAY_ULTIMATE_SOCIAL_ICONS] 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 Read more about 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; Read more about The Future of Bridge Inspection[…]

How To Test Concrete Using Impact-Echo Method

4 NDT Methods for Concrete Imaging and Scanning

Concrete imaging and scanning has been an interesting topic for many materials and structural engineers, inspectors, as well as the owners. It helps identify and quantify sub-surface defects more efficiently, and comprehend the extent of damages. Different non-destructive testing methods have been developed for concrete imaging and scanning. In this article, we will review some Read more about 4 NDT Methods for Concrete Imaging and Scanning[…]

Non-Destructive Evaluation Bridge Abutments

How to Evaluate Bridge Abutments?

In a bridge structure, abutment refers to the substructure unit which supports the end of the structure (bridge span) and retains the approach fill (see Ontario Structure Inspection Manual). Abutments are commonly made of mass concrete, reinforced concrete, or wood. Usually, abutments consist of a number of components: + Foundation + Abutment wall + Ballast wall + Read more about How to Evaluate Bridge Abutments?[…]

Common Defects in Bridge Structures

The collapse of Ponte Morandi in Genoa, Italy (read more) and Florida International University pedestrian bridge (read more) have raised concerns about the safety and reliability of existing and new bridge structures. common Defects in bridge structures can affect the overall safety of the bridge structures. Different deterioration mechanisms can lead to major defects. Exiting infrastructure in Read more about Common Defects in Bridge Structures[…]

Quality Control of Concrete Piles

Quality control of concrete piles is a challenging task. Engineers, and contractors rely on experience and well-established procedures and test standards to verify the strength, and consistency of pile materials. Non-destructive testing help reveal potential defects that might have happened during pile casting (in the case of cast-in-place piles), or transportation and installation (in the Read more about Quality Control of Concrete Piles[…]
