Interactive & Video Discount Package - Alaska Geotechnical and Ethics 24 PDH

This online engineering PDH interactive presentation provides an advanced numerical modelling approach to evaluate rock stability at bridge piers and abutments.

Riprap is one of the most common materials used to protect bridge abutment and pier foundations from scour. A key element of the design of riprap countermeasures is rock sizing, which is based on equations generally derived from simplified laboratory experiments.

This 1 PDH online interactive presentation is intended primarily for designers and engineers responsible for protecting bridge foundations.

This online engineering PDH interactive presentation provides a brief overview of the design and construction of Geosynthetic Reinforced Soil (GRS) abutments and the Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS).

Geosynthetic reinforced soil (GRS) consists of alternating layers of compacted fill and closely spaced geosynthetic reinforcement. The technology has many applications, with bridge support being the focus of this design and construction presentation. This presentation also includes several updates based on continued research conducted at the Federal Highway Administration’s Turner-Fairbank Highway Research Center, as well as user feedback resulting from the use of GRS in the construction of more than 300 bridges.

Revisions include additional details on the design, construction, quality assurance, in-service inspection, maintenance, and repair of the GRS-IBS, along with revised material specifications, site selection criteria, and hydraulic guidance.

This 4 PDH online interactive presentation is applicable to benefit owners, designers, and construction personnel interested in implementing this technology while realizing how to design and construct a GRS-IBS that will have an estimated service life of at least 100 years.

This online engineering PDH interactive presentation provides an overview of design and testing of laterally loaded deep foundations.

Lateral loads in deep foundations occur under various conditions. In some applications, such as noise walls or landslide stabilization, lateral loads are the principal design load. For bridge foundation applications, lateral loads must be fully considered in the design. In many cases, lateral loads control the diameter or width of the foundations.

This 4 PDH online interactive presentation is intended primarily for geotechnical and structural engineers and professionals who are interested in learning more about the selection, design, analysis, and testing of laterally loaded deep foundations.  

This online engineering PDH interactive presentation provides a brief guidance for the design and construction of post-grouted drilled shafts through cost-effective and appropriate use of post-grouting techniques.

Although post-grouting of drilled shafts has been performed for nearly four decades in Europe, there has been limited application of post-grouting in the United States. Post-grouting is typically accomplished using a grout delivery system that is incorporated into a drilled shaft during construction. However, concerns remain regarding the reliance on improved performance for post-grouted drilled shafts.

This presentation summarizes the current state of practice for post-grouting of drilled shafts in the U.S., documents the analyses and evaluations performed to evaluate alternative improvement mechanisms for PGDS, and describes the findings and recommendations developed based on the work performed. The presentation concludes with recommendations for future work needed to improve post-grouting practice for transportation infrastructure.

This 4 PDH online interactive presentation is applicable to civil engineers, construction and transportation planners, designers, and other technical professionals who are involved in the grout distribution services.

This online engineering PDH interactive presentation provides a brief overview on the selection of spread footings on soils to support highway bridge structures.

Foundations for bridges and their appurtenant structures such as retaining walls can be categorized as shallow or deep. The foundation specialist often chooses a deep foundation system because of a variety of reasons that include institutional culture and biases and/or lack of knowledge about rational methods for analysis and design. Based on the research of the Department of Transportation (DOT), a potential cost savings to the public of approximately $135 million was estimated, if one assumes that only 25% of the approximately 600,000 existing bridges in the United States were to use spread footings when they are replaced due to age or other reasons.

This presentation begins by discussing the primary obstacles to the wider use of shallow foundations on soils for highway bridges which often results in the indiscriminate use of costlier and more complex deep foundations. The presentation continues to discuss the Load and Resistance Factor Design (LRFD) methodology to demonstrate that spread footings may be an excellent foundation alternative for fast and low cost, low risk construction on competent native soils, improved in situ soils, and compacted engineered embankment fill materials. Spread footings are not always appropriate, and this presentation can help one identify those situations as well. Using documented performance data, this presentation also presents powerful concepts, such as the use of construction-point analysis and angular distortions, to demonstrate the benefits of using spread footings.

This 2 PDH online interactive presentation is applicable to geotechnical engineers, foundation design specialists, and technical staff who are interested in gaining a better understanding of the use of spread footings as a viable foundation alternative for all bridges.

This engineering online PDH video presentation will offer a thorough overview of modern soil improvement methods for engineers.

This course focuses on the critical role of improving soil conditions that often determine project success. Selecting the right method requires a solid understanding of available techniques and their unique characteristics. Also, this course covers essential methods including wick drains, deep compaction (like vibro-compaction and stone columns), grouting, and ground freezing. It also examines soil mixing and injection techniques such as permeation, compaction, jet grouting, and deep soil mixing.

This 2 PDH online video presentation is intended for civil, geotechnical, structural, and construction engineers as well as professionals seeking to expand their understanding of ground improvement methods.

This engineering online PDH video presentation will deliver a focused, practical overview of non-destructive testing in drilled shafts, designed to help engineers detect and address potential defects.

As critical foundation elements in large infrastructure projects, drilled shafts require precise construction and thorough monitoring to prevent costly issues. This presentation includes a brief history and evolution of drilled shafts, followed by a review of key construction methods and the root causes of common defects.

This video presentation will examine typical construction challenges such as misalignment, poor concrete placement, and other flaws affecting structural integrity. Defects will be categorized, and advanced non-destructive testing techniques like Crosshole Sonic Logging (CSL), Crosshole Tomography (CT), and Sonic Echo (SE) will be introduced. These methods allow for the accurate diagnosis of the drilled shaft without damaging the structure. It also outlines repair techniques and risk mitigation strategies aimed at improving quality control and long-term shaft performance.

This 2 PDH online video presentation is intended for civil, geotechnical, structural, and construction engineers as well as professionals seeking to enhance their understanding of drilled shaft construction and quality assurance through non-destructive testing.

This 2 PDH online video presentation presents the general laws of professional responsibility and ethics governing the practice of engineering in the Unites States.  

The first hour begins by looking at the general ethical expectations of professional engineers with practical applications for each followed by a series of disciplinary cases of engineers disregarding these ethical canons with their resulting professional penalties.

The second hour is all engineering-based ethical case studies selected to stimulate thought and encourage maximum interaction between participants and the presenter.

This 2 PDH online video presentation is intended for all US-licensed professional engineers who must prove continuing professional competency in engineering ethics as a condition of their license renewal.
