4 Excavation Safety Factors to Consider

Safety is one of the most important factors in construction build projects. If you think about every single landmark, building, road, and bridge that are currently in your city, each and every one of these were once constructed. They were built with easy accessibility and durability in mind, and most importantly, with safety in mind. Safety involves each of the following considerations.

Safe excavation shoring methods
Excavation shoring methods are needed when a temporary support system is needed for a building. Sometimes the excavation shoring is sitting beneath water, such as with bridges, and sometimes it is on land. It usually involves removing a part of the earth to build the temporary structures. Either way, the temporary excavation allows workers to construct a safe building or bridge, while holding up the sides until it is finished. This increases safety for both the workers and the pedestrians who may still be using the bridge during construction.

OHSA currently defines an excavation as any man made cut, cavity, trench, or depression in the earth?s surface formed by earth removal. A trench is defined as a narrow underground excavation that is deeper than it is wide, and is no wider than 15 feet (4.5 meters). Excavations may vary beyond that to better meet the needs of the building or structure that is being built.

Safe excavation location
A lot of thought and consideration goes into the location of the excavation shoring methods. The construction propping system must be placed in a location that can safely hold the weight. Sometimes, a modular trench shield might be used. Trenches 5 feet (1.5 meters) deep or greater require a protective system unless the excavation is made entirely in stable rock. Trenches 20 feet (6.1 meters) deep or greater require that the protective system be designed by a registered professional engineer or be based on tabulated data prepared and approved by a registered professional engineer. The specific location and type of excavation or trench used will depend on the project and where it is being built at.

Safety when it comes to large excavation shoring projects
Sometimes, extremely large excavation shoring is needed to support much larger of projects. These excavation shoring methods differ from smaller to medium sized projects because the heavier the materials, the greater and more durable that the support needs to be. However, it is important to visit 619 Roofing website in order to know that there are limits in how deep the excavation shoring methods can go.

Earth excavation to a depth of 2 feet (0.61 m) below the shield is permitted, but only if the shield is designed to resist the forces calculated for the full depth of the trench and there are no indications while the trench is open of possible loss of soil from behind or below the bottom of the support system. These safety precautions are to protect both construction workers and the integrity of the planet. Too much excavation shoring could eventually harm the condition of the Earth.

Types of excavation shoring projects
Excavation shoring methods may be used for a variety of construction projects. Some of these projects include the build of a new bridge, new road construction over waterways, and the build of a new building that is partially supported by the ground underneath water. These types of projects require very specialized excavation methods and often require many months, sometimes years of design and planning.

OSHA puts safety as a top priority in the build of new construction projects. These safety precautions, including which excavation shoring methods to use, how far to excavate, and safety tools used are for the protection of workers, nearby residents, and even the planet. It is crucial that we protect the planet that we live on as we continue to build onto it.
