Trenching and Excavation

Trenching is an important aspect of many construction projects, mainly pipe laying projects for civil works, mining services, telecommunication projects and other related projects. The success of a trenching project is influenced by many factors, but the main one is the type of trenching method that will be adopted. Proper study and evaluation are required first and foremost before a suitable trenching method is used.

Methods of Trenching

Trenching can be done using one or a combination of different methods. Project managers, engineers and designers look at the cost, the type of infrastructure to be built and the government regulations in deciding which methods to use. Trenches can be done using the open cut system, where the trench is sloped to an angle.

Trenching can also be done using speed shoring, which uses beams to support the trench walls. Trenching projects can be done by building trench boxes where the workers can safely work in the trench. Other methods involve drilling H-pile with lagging shoring, interlocking steel piles and modular shoring. Not one method is superior to another. You need to evaluate them carefully to understand the pros and cons before deciding which technique to use.

Things to Consider When Excavating

Excavating for trenches is enormously complicated. There are many things to consider when designing trenches so as to ensure that they will operate as expected and that there will be no safety issues or structural issues afterwards.

Safety and environmental concerns may be the top consideration when planning and designing trenches. Although these considerations are not directly focused on construction, they can be a hindrance to the success of a project if they are not considered in the first place. Excavators must adhere to safety and environmental standards, such as what earthmoving specialist Dee Gees Bobcats is doing.

Cost is another big factor in determining how the trenching project will go. Selecting the right trenching method for a particular area will help keep the project cost to a minimum.

The physical conditions of the area should also be evaluated thoroughly. This will involve a complete study of the soil type and groundwater as well as the presence of any man-made structures underground. The method to use in trenching will be heavily influenced by the soil type and the presence of groundwater. For very hard and rocky areas, equally strong earthmoving equipment will be required.

Work and cost efficiency will be improved if the project manager manages to find a reliable contractor and plant hire. Dee Gees Bobcats can provide for all excavation and trenching solutions with its wide range of earthmoving machines. For more information on the company’s services, visit its website at
