Excavation Steps followed by Construction Companies

Before you can start building, much work goes on behind the scenes done by construction and excavating companies. Excavation is the very first phase in the building process and one of the most critical stages. Excavation construction is not always straightforward and is not usually cheap, but it is an essential step to ensure the longevity of your buildings. Excavation is necessary for a solid foundation on which the building erection process will take place.

What Is Excavation Construction?

Excavation is the process of using tools, machinery, or explosives to move items like dirt, rock, or other materials. It is part of the earthwork, trenching, wall shafts, tunneling, and subterranean. Exploration, environmental rehabilitation, mining, and building are all critical uses for excavation. It is essentially used in the construction industry. Excavation construction provides foundations for buildings, reservoirs, and highways. The processes involve various techniques, including trenching, digging, dredging, and site development. These operations will need specialized skills, tools, and machines to complete the work correctly. Your project and the items you need to construct will determine the method you employ.

The excavation steps include:

  • Surveying ground and top levels
  • Marking the boundaries of the building
  • Setting corner benchmarks
  • Dressing the loose soil
  • Excavation to the approved depth
  • Marking up the cut-off level
  • The construction of dewatering wells and interconnecting trenches
  • The construction of protection drains

The Starting Point

Excavation construction begins once a plan has been approved. The excavator will look up your authorized design and drawings to determine where to dig. The digging depth will be determined by several things, including the type of foundation and whether or not there will be a crawl space or basement. Whatever form of foundation you pick, it will almost certainly require cement footers. The depth of your footers will be determined by the foundation you pick. In the sections below, we will look at a few different foundation types and how they affect excavation in construction.


As the name implies, a slab is the most basic foundation type. When you build on a slab foundation, you will have a lot of alternatives and variables to work with. You must ensure that your slab foundation will withstand the elements in your area, such as satisfying frost mitigation criteria. Such requirements can drive the cost to the point where it is more cost-effective to construct a basement or crawlspace.

Crawl Space

Crawl spaces have recently been one of the most popular possibilities widely backed by excavating companies. To protect the foundation from frost, you will need at least 30 inches of excavation in your crawl space. If you are building in the mountains, a minimum of 36 to 40 inches is usually required. Crawl spaces are frequently assumed to bring significant cost savings when building a home. This is not the case because most of the excavation expense is spent transporting the equipment to the job site and getting it started, followed by carrying everything away. It will not affect the final cost if you have to excavate an extra 4 to 6 feet.


The most common type of foundation is a basement. It offers a robust foundation system as well as additional storage space. Full basements, garden levels, and walkouts are the three basic types of basements. Excavation steps of a complete basement cost more than the other forms of foundations. When the cost of the basement is compared to the cost of the other choices, it becomes clear that the basement offers the best value for money.

How Long Does It Take?

Remember that several factors influence the time it takes to dig your project site, and times might vary significantly. On the other hand, completing the excavation construction steps for a foundation can take anything from 3 to 4 days to 3 weeks. In most cases, a 10-foot over-dig is the worst-case situation. This is more likely to happen in places with huge stones or if you get trapped in clay.


When dealing with massive projects, excavation demands expertise, talent, and attention to detail since it lays the groundwork for the entire project. Professional excavating companies like Helms Construction employ modern procedures, equipment, and machinery to guarantee that the project is done correctly. We ensure the greatest possible outcome when implementing the excavation steps.
