Is it time to transform your Newport Beach property? Excavations are major undertakings that need to be done right. Let's check out the basics for an effective undertaking.
Safety is absolutely crucial on an excavation site due to the high risk factor of heavy machinery and material, as well as the hidden hazards of collapsing ground, subsurface plumbing and electrical cables. Hitting them can be a disaster. Their position needs to be located on a diagram and then labeled with stakes on the excavation site first and foremost.
Hand tools will need to be used when in proximity to underground infrastructure. A combination of precision and strength is needed to excavate large areas effectively. If you are a homeowner, your contractor will know what areas they can use heavy machinery for and where they need to do the hard work with hand tools.
Other major safety considerations involves keeping dirt, materials, and machinery away from the edges of the excavation sites. If these become too heavy the sides can collapse and potentially injure workers, as well as cause project delays. A qualified landscape contractor will have procedures in place to prevent this, and any other dangers, from occurring.
Survey the Lay of the Land
Before an excavation begins the land must first be surveyed. Hills and slopes need to be taken into consideration, as well as obstructions like rocks and trees. The area for the site also needs to be measured and laid out to the highest accuracy. A low level of accuracy in this step can lead to costly re-excavations or re-leveling.
Test the Soil
Certain soils may not be compatible with the job. It may need to be treated before the digging begins or an area with different soil may need to be located to accomodate the project. The reason for this is that certain soils cannot support heavy structures effectively. Other types of soil can be strongly affected by expansion or compaction due to water conditions or temperature.
If you're excavating for the foundations of an outdoor building or another important structure, corrective measures must be taken to eliminate the risk of ground destabilization, or a delay in proceeding due to drainage issues.
Removal of Groundwater
Certain areas of your site can be affected by large amounts of wastewater. In this case, a pump line will need to be drilled into the excavation area. If not removed, the water can cause chaos by flooding the worksite.
One method to manage this is to excavate the deepest area first. From then on groundwater will run straight down to this area where it can be pumped out. If the shallowest area gets excavated first, this can cause water to constantly flood the work area as workers move deeper and deeper.
The evidence of groundwater depends largely on your property’s location. A professional will be able to determine the water table for your area, and what effect this will have on deep excavation projects.
Removal of Soil
If you’re undertaking a large scale project, such as pool construction, this can require moving massive amounts of dirt. A large area for this excess must be located and be free of any obstructions. Excavation equipment can then be used to remove the dirt. The volume of ground extracted during such a project is often underestimated by homeowners, and requires periodic removal while the job is in progress.
