Civil works may require the property owner to do some excavation to prepare the ground for the houses. Whether you are in Australia or anywhere across the globe, choosing the right excavation method will end up saving your time and money.
Unlike some decades ago, when it was hard to get the right method, it has now become very easy to get an excavation method that suits your needs and preferences. Thanks to the advanced level of technology in our modern world.
Civil workers and other experts should carry out thorough excavation research before deciding to use any excavation method. It is good to note that not every excavation method can be used in any civil works.
That’s why we are going to take you through some of the factors that excavation companies in research check for to determine the kind of excavation method. So let’s get started.
Factors to Consider when Choosing the Excavation Method
1. The water table
Well, every site in Australia has to be measured of the groundwater before the excavation process commences. If the water table is high, then the excavators will find themselves in a hard situation. One of the major problems that experts find themselves in is having some water-filled trenches as they excavate. To overcome the problem, they have to use some dewatering pumps to pump the water out of the trench. So how high or low the water table is, determines the kind of groundwater.
2. The size of the project
How huge the project is to determine the technique and the method of excavation the civil workers should use. If the project is going to take place in a small area, then you have to use an excavation method that fits the area. For example, when carrying a relatively medium-sized excavation, you cannot use some excavation methods like the sequencing method. However, this method could be essential for larger projects.
3. The subsoil
Have you ever asked yourself why experts have to do some survey before deciding on the type of excavation to apply in a site? The reason is simple. They want to determine the type of subsoil in the region. If the subsoil is soft, then the kind of excavation to be used will be light. That should tell you that some excavation methods like the shoring method can never be used in a site where you have subsoil. It is, therefore, advisable to hire an expert to research how compact the soil is.
4. The conditions that surround the site
Some sites are surrounded by buildings and other residential places. In case the site is not in an open field, the contractor may decide to avoid some explicit excavation method. If some heavy excavation methods are used, then there is a possibility of the surrounding buildings collapsing. That can be an extra cost to the contractors and site owners.
5. Costs
How much budget have you set aside to do the job? Well, this is another major factor that should not be ignored if the right excavation method is to be deployed. The more complex the method is the more likelihood of digging deeper into your wallet. The costs could be determined by the surrounding sites, the type of excavation method one is planning to use, and the size of the project. However, the site owner should stick within his or her set budget. Besides, they should have interaction with various contractors to choose the best that meets their needs.
