The present online engineering course provides an excellent opportunity to sharpen your skills and knowledge of how to design, manage and constructing successful cut and cover tunnels for infrastructure projects. The media rich content includes photos and videos of major projects, many associated with the post 9/11 reconstruction of lower Manhattan, and is presented by a construction industry expert, Mr. 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.
