The 3 Most Common Deep Foundation Integrity Test Methods

Pile Integrity Tester deep foundation Kansas City

Successful projects all start with planning and design, end with construction, and include quality programs for every step. For successful deep foundation projects, that means quality control and assurance to validate design assumptions and determine if the deep foundation was installed as planned. To do this we perform integrity testing, which is a set of nondestructive tests that assist engineers as they evaluate the in-place condition of a deep foundation. What are the most used test methods for deep foundation integrity testing? Braun Intertec performs integrity tests most often on drilled, deep foundations since the act of driving a pile...

Deep Foundations Integrity Testing Webinar: An Undervalued Quality Assurance Test

Deep Foundations Integrity Testing Webinar

Deep foundations provide the key support for most heavy structures but how can you confirm your newly installed foundations will function as specified? The answer often is integrity testing, a critical, yet underutilized, test method for projects with deep foundations. Integrity testing is valuable for any kind of deep foundation project which can include, high rises, bridges, transmission poles/towers as well as docks and wharfs. These projects often present numerous factors which can influence the type of integrity test best suited for the project from soil resistance, material properties (strength, density, etc.), reinforcement within the deep foundation, and the length...

Structure Support On Laterally Swept Piles

Load Testing

Anyone who has observed a significant number of piles has seen that, inevitably, the pile is not perfectly straight after driving. In spite of the best efforts of contractors, there are a whole host of reasons for piles to end up out-of-plumb or to have a curve, sometimes referred to as pile sweep. For two, recent projects with numerous swept pile, the available research was determined to be limited in application given the investigated pile sizes, lengths and measured sweep. As a result, the project team chose to perform static load testing to evaluate the ultimate resistance of the swept...

Deep Foundations Part II: Proving Their Strength

35W Bridge Construction

In Part 1 of our blog series we discussed the different types of deep foundations and some of what goes into their design. Once a deep foundation system is selected and load requirements are determined, the process of constructing them begins. In this post, we will focus on quality control and integrity testing related to deep foundations. Successful deep foundation projects include quality programs to validate the design assumptions and determine if the contractor can install the deep foundation as planned. For most projects, the quality program is structured around two distinct operating procedures: observations and testing. Observations Observations have been a part...
