Excavations and earthworks

Excavation and earthmoving services in an industrial context

Excavations and earthworks consist of operations of removal and subsequent transportation of materials to environmental restoration plants, treatment plants, or inert landfills.
Handling involves the phases of moving and shaping the terrain, often carried out as part of construction projects, civil engineering, road works, and similar activities.

Thanks to our highly qualified staff and a significant fleet of vehicles, we are able to provide a complete excavation and earthworks service, directly managing all phases of the planned interventions. 

The excavations we carry out

Building excavation works are not all the same and require different procedures.

Regardless of the size of the excavation to be carried out, it is important to distinguish between cutting excavation and embankment excavation.
We carry out these operations using machinery such as tracked excavators, wheeled/crawled mechanical shovels, bulldozers, or other specific equipment depending on the type of excavation.

We deal with excavations for the subsequent construction of foundations, basements, irrigation channels, artificial lakes, and similar works.

Furthermore, we also perform selective point excavations, even in areas defined as " remediation areas ". These are very complex and articulated interventions, necessary to eliminate sources of contamination or polluting substances, or to reduce the concentrations of the same present in the soil, subsoil, and groundwater. This is a strategic operation that allows:

  • recovering areas compromised by contamination phenomena;
  • eliminating potential risks to the environment and human health.

The aim of these interventions is to bring the concentrations of pollutants below the risk threshold (CSR)/Contamination (CSC), and consequently requalify the territory. 

Earthworks: types of intervention

The types of interventions are multiple. Among the most common are: 

  • Excavation
    It includes the removal of soil, rocks, and other materials to create or modify ground surfaces, through the use of excavators, bulldozers, backhoes, and other machinery.
  • Leveling
    It consists of eliminating irregularities in order to create a uniform surface. - Soil compaction: It is carried out to increase the density of the soil and make it more resistant. This activity is performed with the help of compaction rollers and vibrating plates.
  • Excavation
    It is carried out for the construction of foundations, drainage networks, gas pipes, water pipes, and other services.
  • Soil consolidation
    It is performed to improve the stability of the soil and reduce the risk of landslides and settlements.
  • Preparation of land for agriculture
    It involves preparing the soil for sowing, removing any obstacles, and leveling the surface.

How do we operate

We have an internal technical structure dedicated to detailed planning of interventions in accordance with Legislative Decree 81/2008. Our Technical Office is responsible for the preliminary analysis of each phase of the work, starting from the site setup, and prepares safety operational plans with related supporting graphic materials.

In order to minimize risks both in terms of safety and the environment, each site is thoroughly studied to be able to preliminarily and effectively address any issues, allowing for real-time resolution of any potential interferences.

Before starting an excavation and earthmoving, it is necessary for all parties involved (with particular reference to the Employer) to clearly assess certain aspects:

  • the purpose for which the excavation must be carried out;
  • the presence of underground services and/or overhead lines;
  • the presence of structures adjacent to the area to be excavated;
  • the activities that will have to be carried out within it;
  • the dimensions of the works to be carried out within the excavation and their location;
  • the nature and consistency of the soil;
  • the presence of any space-time constraints;
  • the need/possibility to carry out the excavation at different times, thus limiting the time of open excavations;
  • the means available for excavation activities;
  • the possibility of storing part or all of the resulting material within the construction area and eventually defining and ensuring that its placement does not create risks for the workers;
  • the availability of adequately trained and trained personnel, with specific reference to earthmoving machinery. On this point, there are two relevant figures that operate before and during the execution of the work:
    • The Safety Coordinator in the Design Phase, who verifies the existence of safety conditions before the start of the work;
    • The Safety Coordinator in the Execution Phase, who monitors the continuity of such conditions during the execution of the work.

At the beginning of the work, certain provisional measures must also be prepared, always aimed at protecting the workers: prevention and guarantee measures already developed during the design phase, following the previously prepared Safety and Coordination Plan.

Only after defining all the necessary aspects to operate safely, can the actual excavation activities begin.

Fleet of vehicles

In the handling of excavation materials on construction sites, mechanical shovels and crawler excavators are used; the soil is normally loaded onto 4-axle work vehicles and in special cases onto dump trucks.

Let's give some examples:

  • Crawler excavator Hyundai HX235ALCR
  • Crawler excavator Hyundai HX300ANL
  • Crawler excavator Hyundai HX220NL
  • Crawler excavator Hyundai R520LC-9
  • Crawler excavator Hyundai R450LC-7
  • Crawler excavator Volvo EC235DNL
  • Wheeled loader Komatsu WA 430-6
  • Wheeled loader Komatsu WA 389-8
  • Wheeled loader CAT 972M
  • Wheeled loader DOOSAN DL350-5
  • Dynapac CA362D roller

Some examples

Wide section excavation and subsequent transport for environmental restoration
Wide-section excavation with selective picking of the soil and heterogeneous materials, for accumulation in platforms inside the construction site
Spot excavations for water pipeline

For the management of excavation materials, we adopt solutions that are compatible with the environment, with a focus on circular economy.

Excavations referred to as "earth and rock from excavation" (used for the construction of roads, concrete structure foundations, underground parking, etc.) involve the production of a significant quantity of materials for which, in most cases, a sustainable management is provided, mainly aimed at reusing resources within the scope of environmental requalification projects for disused quarry sites.

Once extracted, the excavation materials undergo checks and analyses to verify that the parameters meet the identified requirements for the protection of human health and the environment.
Thanks to our internal Analysis Laboratory, we determine the analytical characteristics of the soil for its subsequent management. This classification of excavation materials allows us to identify the best conditions for their reuse and, consequently, to reduce the amount of waste to be disposed of.

This passage is of great relevance for companies that, thanks to our consultancy, have the opportunity to leave a positive impact on the environmental protection process, as well as to save considerable economic losses.
