We drive on interstate, cross large bridges, and wait at complicated traffic signals. Even though we are constantly surrounded by the marvels of this nation’s construction and technology, few of us really understand all that is involved in the creation of the highways, interstates, traffic signals, bridges, and other parts of this country’s infrastructure.
Although we may catch a glimpse of a few construction workers jack hammering old sections of road or pouring concrete for the new repairs, few of us realize that beneath the surface of these above the ground tasks are a complicated and well designed system of excavation shoring devices that both ensure the integrity of the resulting structure, as well as protect the workers during the entire construction process.
The fact of the matter is excavation shoring design ins essential is essential to many projects. Although it is work that is unseen by the general public, excavation shoring design is constructed and in place before any temporary road construction project opens and before any temporary bridge construction occurs. Regulated by federal mandates, trenches range in size according to the kind of project they are used for, and every one of these open trenches requires some kind of shoring plan so that the project, and more importantly, the workers are protected. For instance, trenches five feet deep or greater require a protective system unless stable rock is the basis for the entire project. Trenches 20 feet deep or greater require a protective system be designed by a registered professional engineer or, as an alternative, be based on tabulated data that has been either prepared and/or approved by a registered professional engineer.
Although we are all impacted by the road and bridge construction projects that we encounter when we travel, few of us understand the reasons that many of these projects require the time and financial commitment that can last for months. Understanding, however, that structural shoring towers can increase safety by reducing the need for detours and closures when bridge work is in process means that temporary roadways are the key to keeping many projects going, even when unexpected weather can cause serious complications.
Of the 600,000 bridges in America, one in nine of the these are rated as structurally deficient. Given that the average age of the nation?s 607,380 bridges is currently 42 years it is likely that the process of excavation shoring design and trench box industries will have a major impact on the many successful and safe future renovation projects.
