Ontario Structural 30 PDH Discount Package 2

This engineering online PDH course will provide an overview on the evaluation of tunnel systems and the associated components. The components explored in this chapter include the typical personnel involved, supplemental inspection and testing methods, risk-based assessments, priority classification, and basic cost estimating. Information is also provided on load rating.  

Evaluations are normally performed after the inspection data is received. Sound engineering judgment is used to evaluate the consequences of tunnel system or component failure in terms of overall safety, service level, and costs. In some instances, supplementary inspections and testing may be needed where data is lacking. Risk assessment techniques should include strategies for deploying, operating, maintaining, upgrading, and disposing of tunnel system components in a cost-effective manner.

This 2 PDH online course is applicable to civil and structural engineers, as well as design and construction personnel involved with the evaluation process of tunnel systems.

This online engineering PDH course provides guidance on the design and construction of conduits, culverts, and pipes, as well as design procedures for trench/embankment earth loadings, highway loadings, railroad loadings, surface concentrated loadings, and internal/external fluid pressures.

In general, reinforced concrete conduits, culverts and pipes are used for dams, urban levees, and other levees where public safety is at risk or substantial property damage could occur. Corrugated metal pipes are acceptable through agricultural levees where conduits are 900-mm (36-in.) diameter and where levee embankments are not higher than 4 m (12 ft) above the conduit invert. Inlet structures, intake towers, gate wells, and outlet structures are usually concrete. However, corrugated metal structures may be used in agricultural and rural levees.

This 4 PDH online course is applicable to civil, structural and geotechnical engineers, as well as design and construction personnel involved with the design and installation of conduits, culverts and pipes.

This engineering online PDH course will provide an overview on the inspection of tunnel systems and the associated components.

This course focuses on developing safety inspections for highway tunnels. Some of the essential requirements of the NTIS are summarized to include the responsibilities of the tunnel inspection organization, qualifications of inspection personnel, inspection procedures and practices, and the different types of tunnel inspections. This course also explores health and safety issues for inspectors, inspection equipment, typical tunnel defects, owner defined elements, critical findings, and condition ratings. A glossary of selected terms and a list of references is also included at the end.

This engineering online PDH course will provide an overview on effective maintenance considerations of tunnel systems and the associated components.

An effective maintenance program helps reduce costs, decrease the number of tunnel closures, increase public safety, and ensure adequate levels of service. To maximize efficient use of resources and minimize costs, maintenance programs should be optimized. When large-scale repairs and upgrades are implemented, these projects are typically referred to as tunnel rehabilitation.

This online engineering PDH course provides basic information on the capabilities of sonar technologies in performing underwater bridge inspections and its benefits in supplementing dive inspectors to improve inspections.

The requirements for underwater bridge inspection procedures using divers are well documented within the U.S. However, some bridge inspectors and owners have increasingly been supplementing dive inspections with acoustic imaging technology to enhance inspection quality, increase safety, increase efficiency, and improve documentation of findings. This trend has accelerated, in part, because of advancements in sonar technology. The trend has also accelerated because site conditions adverse to dive inspections—such as limited underwater visibility, high velocity currents, submerged debris, and extreme water depths—exist at many bridge sites.

Because these adverse conditions can limit a diver’s ability to inspect a bridge below water, many states are investigating the use of sonar technologies for underwater bridge substructure inspection. FHWA provides overall guidance for these inspections and recognized the need for a comprehensive evaluation of the capabilities of sonar technologies for this important activity. In this study, a range of sonar technologies are evaluated in a variety of underwater conditions to determine how these technologies can be effectively used in conjunction with or independently of divers.
