Intended Audience: Civil Engineers, Managers and Construction Practitioners


Get the basic and advanced skills to support excavation projects including the best practices for the construction and installation of Secant Pile Walls and Scurry Walls. This online course is an excellent opportunity to sharpen your skills for designing, managing and constructing successful excavation projects. The media rich content includes photos and videos of major excavation projects, many associated with the post 9/11 reconstruction of lower Manhattan, and is presented by a recognized construction industry expert, Irwin Weinbaum. H.R.3684 - Infrastructure Investment and Jobs Act 11/15/21 The Bipartisan Infrastructure Act will rebuild America’s roads, bridges and rails, expand access to clean drinking water, ensure every American has access to high-speed internet, tackle the climate crisis, advance environmental justice, and invest in communities that have too often been left behind. Now that funds are available, the challenge is to develop the workforce necessary to successfully execute this ambitious program. We have compiled eighteen one-hour classes focused on the basic means and methods of constructing Infrastructure Projects. The media rich content demonstrates   construction details common to a wide variety of projects and will be invaluable to designers, builders and owners and help to insure successful outcomes.
